Impaired lysosomal processing of beta2-microglobulin by infiltrating macrophages in dialysis amyloidosis. (1/1787)
BACKGROUND: Macrophages may participate in amyloid fibril formation by processing the protein precursor. Although this theory seems to apply for amyloidosis, in which proteolytic cleavage is a prerequisite for amyloid fibril formation, it has not been demonstrated for beta2-microglobulin (beta2m) amyloidosis. We aimed to establish the role played by macrophages in beta2m amyloidosis. METHODS: We used a double immunogold electron microscopy technique, including mouse antihuman CD68, rabbit antihuman beta2m, amyloid P component, and lysosome-associated membrane protein (LAMP-1) antibodies. Differential density labeling studies of beta2m and amyloid P component were performed extra- and intracellularly to assess protein processing by macrophages. RESULTS: The cells surrounding amyloid fibrils were found to be mostly CD68 positive, suggesting that they were of monocyte-macrophage lineage. Intracellular accumulation of amyloid fibrils was also observed; these fibrils were constantly surrounded by LAMP-1-linked gold particles, demonstrating that intracellular beta2m was almost exclusively lysosomal. The rough-surface endoplasmic reticulum was not labeled by beta2m antibody, suggesting that there was no active synthesis of beta2m by the cells. As a marker of endocytosis, protruded cytoplasmic processes in close relation with the intracellular accumulations of beta2m amyloid fibrils were observed. No difference in density labeling (extracellular vs. intracellular) was observed for beta2m, whereas intracellular P component labeling was significantly decreased. CONCLUSIONS: All of these data are strongly suggestive of phagocytosis and not synthesis of amyloid fibrils by macrophages. Further, they demonstrate an impaired lysosomal processing specific for beta2m, as other compounds of the amyloid fibrils (P component) are significantly cleared. (+info)The heparin/heparan sulfate-binding site on apo-serum amyloid A. Implications for the therapeutic intervention of amyloidosis. (2/1787)
Serum amyloid A isoforms, apoSAA1 and apoSAA2, are apolipoproteins of unknown function that become major components of high density lipoprotein (HDL) during the acute phase of an inflammatory response. ApoSAA is also the precursor of inflammation-associated amyloid, and there is strong evidence that the formation of inflammation-associated and other types of amyloid is promoted by heparan sulfate (HS). Data presented herein demonstrate that both mouse and human apoSAA contain binding sites that are specific for heparin and HS, with no binding for the other major glycosaminoglycans detected. Cyanogen bromide-generated peptides of mouse apoSAA1 and apoSAA2 were screened for heparin binding activity. Two peptides, an apoSAA1-derived 80-mer (residues 24-103) and a smaller carboxyl-terminal 27-mer peptide of apoSAA2 (residues 77-103), were retained by a heparin column. A synthetic peptide corresponding to the CNBr-generated 27-mer also bound heparin, and by substituting or deleting one or more of its six basic residues (Arg-83, His-84, Arg-86, Lys-89, Arg-95, and Lys-102), their relative importance for heparin and HS binding was determined. The Lys-102 residue appeared to be required only for HS binding. The residues Arg-86, Lys-89, Arg-95, and Lys-102 are phylogenetically conserved suggesting that the heparin/HS binding activity may be an important aspect of the function of apoSAA. HS linked by its carboxyl groups to an Affi-Gel column or treated with carbodiimide to block its carboxyl groups lost the ability to bind apoSAA. HDL-apoSAA did not bind to heparin; however, it did bind to HS, an interaction to which apoA-I contributed. Results from binding experiments with Congo Red-Sepharose 4B columns support the conclusions of a recent structural study which found that heparin binding domains have a common spatial distance of about 20 A between their two outer basic residues. Our present work provides direct evidence that apoSAA can associate with HS (and heparin) and that the occupation of its binding site by HS, and HS analogs, likely caused the previously reported increase in amyloidogenic conformation (beta-sheet) of apoSAA2 (McCubbin, W. D., Kay, C. M., Narindrasorasak, S., and Kisilevsky, R. (1988) Biochem. J. 256, 775-783) and their amyloid-suppressing effects in vivo (Kisilevsky, R., Lemieux, L. J., Fraser, P. E., Kong, X., Hultin, P. G., and Szarek, W. A. (1995) Nat. Med. 1, 143-147), respectively. (+info)Colchicine inhibition of the first phase of amyloid synthesis in experimental animals. (3/1787)
Colchicine was found to inhibit the first phase of casein-induced synthesis of murine amyloid. When mice were treated with colchicine during the first 7 days of an amyloid induction regimen or when colchicine was given to the donor mice in a transfer model, the amyloidogenic stimulus of casein was blocked completely. Amyloid synthesis was however, not interrupted by the administration of colchicine during the last 7 days of the casein regimen nor by colchicine treatment of recipient mice in a transfer model. (+info)Cells with clonal light chains are present in peripheral blood at diagnosis and in apheretic stem cell harvests of primary amyloidosis. (4/1787)
In primary systemic amyloidosis, small numbers of bone marrow plasma cells secrete monoclonal light chains that form extracellular fibrils (amyloid) in various organs. Evidence limited to a few cases suggests that rare clonal elements can also be found in the peripheral blood (PB), and this may be relevant in PB stem cell autotransplantation. Since up to 40% of amyloid clones do not synthesize heavy chains, in order to detect tumor cells with high specificity and sensitivity we developed a seminested allele-specific oligonucleotide polymerase chain reaction for tumor light chains. Clone-related sequences were detected in DNA and/or cDNA from the PB cells of eight of 10 patients at diagnosis and from apheretic collections of three of four cases undergoing PB progenitor autotransplantation. Since there are experimental data suggesting that circulating tumor cells may be involved in the growth of the amyloidogenic clone and may be chemoresistant, these findings are relevant to the use of leukapheresis purging strategies for PB progenitor autotransplantation in amyloidosis. (+info)The degrees of plasma cell clonality and marrow infiltration adversely influence the prognosis of AL amyloidosis patients. (5/1787)
BACKGROUND AND OBJECTIVE: Primary amyloidosis is a lethal form of plasma cell (PC) dyscrasia characterized by deposits of monoclonal immunoglobulin light chains that cause organ dysfunction. In contrast to multiple myeloma, the amyloid clone is typically indolent and of small size, and marrow PC clonality is not always apparent. This is generally investigated by analyzing the light chain isotype ratio in bone marrow PC. We investigated whether the degree of PC infiltration (PC%) and clonality (PC isotype ratio) affected survival in 56 consecutive patients with primary amyloidosis. DESIGN AND METHODS: PC% was determined by morphologic examination. Immunofluorescence microscopy was used to determine the PC light chain isotype ratio. Statistical analysis was carried out using Cox regression models. RESULTS: The degrees of PC clonality and infiltration were inversely correlated with survival (PC isotype ratio, p = 0.001; PC%, p = 0.008). The two variables were weakly correlated (p = 0.02; r = 0.3). Bone marrow PC isotype ratio demonstrated a powerful independent prognostic value at multivariate analysis when analyzed together with congestive heart failure (the major known negative prognostic factor) and PC%. k/l ratio cut-off values of 0.2 (l patients, p = 0.022) and 16 (k patients, p = 0.03) discriminated two groups with a similar number of patients and significantly different survivals. INTERPRETATION AND CONCLUSIONS: PC clonality and marrow infiltration are important parameters that influence prognosis, presumably because they reflect the amount of pathogenic light chain synthesis. (+info)Organ-specific (localized) synthesis of Ig light chain amyloid. (6/1787)
Ig amyloidosis is usually a systemic disease with multisystem involvement. However, in a significant number of cases amyloid deposition is limited to one specific organ. It has not been determined if the Ig light chain (LC) amyloid precursor protein in localized amyloidosis is synthesized by circulating plasma cells with targeting of the amyloid fibril-forming process to one specific organ, or whether the synthesis of Ig LC and fibril formation occurs entirely as a localized process. In the present study local synthesis of an amyloid fibril precursor LC was investigated. Amyloid fibrils were isolated from a ureter that was obstructed by extensive infiltration of the wall with amyloid. Amino acid sequence analysis of the isolated fibril subunit protein proved it to be derived from a lambdaII Ig LC. Plasma cells within the lesion stained positively with labeled anti-lambda Ab and by in situ hybridization using an oligonucleotide probe specific for lambda-LC mRNA. RT-PCR of mRNA extracted from the tumor and direct DNA sequencing gave the nucleotide sequence coding specifically for the lambdaII amyloid subunit protein, thus confirming local synthesis of the LC protein. (+info)Histological characteristics of sternoclavicular beta 2-microglobulin amyloidosis and clues for its histogenesis. (7/1787)
BACKGROUND: The pathogenesis of beta 2-microglobulin amyloidosis (A beta 2m) has yet to be fully elucidated. METHODS: We describe the distribution and extent of A beta 2m deposition and macrophagic infiltration in cartilage, capsule, and synovium of sternoclavicular joints obtained postmortem from 54 patients after 3 to 244 (median 46) months of dialysis. Twenty-four nonuremic patients served as a control group. The diagnosis of amyloidosis (A) rested on a positive Congo Red staining (typical birefringence) and that of A beta 2m on positive immunostaining of the A deposits with a monoclonal anti-beta 2m antibody. The size of A deposits was measured. RESULTS: A beta 2m was detected in 32 (59%), and non-beta 2m amyloid (Anon beta 2m) was detected in an additional 8 (15%) of the 54 dialyzed patients. A beta 2m deposits were present in the cartilage of all A beta 2m (+) patients (100%). They were localized solely in the cartilage in 27% of the cases, either as a thin patchy layer or as a continuous thicker layer (identified as stage I). A beta 2m was additionally present in the capsule and/or synovium without macrophages in 27% of the cases (identified as stage II). The correlation between the size of cartilaginous deposits and dialysis duration (P = 0.02) as well as with the prevalence (P = 0.03) and size of capsular deposits (P = 0.02) suggests that stage II is a later stage of A deposition. Clusters of macrophages were detected around capsular and synovial amyloid deposits in 46% of the cases (identified as stage III). The longer duration of dialysis in those with stage III as well as the relationship between the size of the A beta 2m deposits and the prevalence of macrophagic infiltration suggests that stage III is the last stage of A beta 2m deposition. Marginal bone erosions were observed in 9 out of 12 patients with stage III deposits. Their size was correlated with that of cartilaginous deposits (P = 0.01). Among the 24 control patients, Anon beta 2m was detected in 12 patients (cartilage 100%, capsule 8%, synovium 30%). CONCLUSIONS: The earliest stage of A beta 2m deposition occurs in the cartilage. A beta 2m subsequently extends to capsule and synovium. These two first stages do not require macrophage infiltration. Macrophages are eventually recruited around larger synovial or capsular deposits in the final stage. Marginal bone erosions develop in this late stage. (+info)Morphological, histochemical, immunohistochemical, and ultrastructural characterization of tumors and dysplastic and non-neoplastic lesions arising in BK virus/tat transgenic mice. (8/1787)
To study the role in AIDS pathogenesis of the human immunodeficiency virus type 1 (HIV-1) Tat protein, a transactivator of viral and cellular genes, we generated transgenic mice with a recombinant DNA containing BK virus (BKV) early region and the HIV-1 tat gene, directed by its own promoter-enhancer. DNA hybridization revealed that the transgene is stably maintained in all organs of transgenic mice as a tandem insertion in a number of copies ranging from 5 to 20 per cell. In addition, tat and BKV RNA were expressed in all tissues. Transgenic mice developed three types of lesions: 1) tumors, 2) hyperplastic and dysplastic lesions, and 3) non-neoplastic lesions. Tumors of different histotypes, such as lymphomas, adenocarcinomas of skin glands, leiomyosarcomas, skin squamous cell carcinomas, hepatomas, hepatocarcinomas, and cavernous liver hemangiomas, developed in 29% of transgenic animals. The majority of tumors were malignant, invasive, and producing metastases. Conversely, tumors of only two histotypes (lymphomas and adenocarcinomas of skin glands) appeared in control mice. Hyperplastic and dysplastic lesions were more frequent in transgenic than in control mice and involved the skin or its adnexes, the liver and the rectum, indicating multiple targets for the activity of the transgene. Pyelonephritis, frequently complicated with hydronephrosis, inflammatory eye lesions, and amyloid depositions represented the most frequent non-neoplastic lesions detected in transgenic mice. Many of the pathological findings observed in this animal model are comparable to similar lesions appearing in AIDS patients, suggesting a relevant role for Tat in the pathogenesis of such lesions during the course of AIDS. (+info)Amyloidosis is a medical condition characterized by the abnormal accumulation of insoluble proteins called amyloid in various tissues and organs throughout the body. These misfolded protein deposits can disrupt the normal function of affected organs, leading to a range of symptoms depending on the location and extent of the amyloid deposition.
There are different types of amyloidosis, classified based on the specific proteins involved:
1. Primary (AL) Amyloidosis: This is the most common form, accounting for around 80% of cases. It results from the overproduction and misfolding of immunoglobulin light chains, typically by clonal plasma cells in the bone marrow. The amyloid deposits can affect various organs, including the heart, kidneys, liver, and nervous system.
2. Secondary (AA) Amyloidosis: This form is associated with chronic inflammatory diseases, such as rheumatoid arthritis, tuberculosis, or familial Mediterranean fever. The amyloid fibrils are composed of serum amyloid A protein (SAA), an acute-phase reactant produced during the inflammatory response. The kidneys are commonly affected in this type of amyloidosis.
3. Hereditary or Familial Amyloidosis: These forms are caused by genetic mutations that result in the production of abnormal proteins prone to misfolding and amyloid formation. Examples include transthyretin (TTR) amyloidosis, fibrinogen amyloidosis, and apolipoprotein AI amyloidosis. These forms can affect various organs, including the heart, nerves, and kidneys.
4. Dialysis-Related Amyloidosis: This form is seen in patients undergoing long-term dialysis for chronic kidney disease. The amyloid fibrils are composed of beta-2 microglobulin, a protein that accumulates due to impaired clearance during dialysis. The joints and bones are commonly affected in this type of amyloidosis.
The diagnosis of amyloidosis typically involves a combination of clinical evaluation, imaging studies, and tissue biopsy with the demonstration of amyloid deposition using special stains (e.g., Congo red). Treatment depends on the specific type and extent of organ involvement and may include supportive care, medications to target the underlying cause (e.g., chemotherapy, immunomodulatory agents), and organ transplantation in some cases.
Familial amyloidosis is a genetic disorder characterized by the buildup of abnormal protein deposits called amyloid fibrils in various tissues and organs throughout the body. These abnormal protein deposits can cause damage to the affected organs, leading to a variety of symptoms.
There are several types of familial amyloidosis, but the most common type is transthyretin-related hereditary amyloidosis (TTR-HA). This form of the disorder is caused by mutations in the TTR gene, which provides instructions for making a protein called transthyretin. Transthyretin is a transport protein that helps move thyroid hormones and vitamin A around the body. In TTR-HA, mutations in the TTR gene cause the transthyretin protein to misfold and form amyloid fibrils.
Symptoms of familial amyloidosis can vary widely depending on which organs are affected. Commonly affected organs include the heart, kidneys, nerves, and gastrointestinal tract. Symptoms may include:
* Heart problems such as arrhythmias (irregular heartbeat), heart failure, or cardiac conduction abnormalities
* Kidney problems such as proteinuria (protein in the urine) or kidney failure
* Nerve damage leading to numbness, tingling, or pain in the hands and feet, or autonomic nervous system dysfunction affecting digestion, bladder function, or blood pressure regulation
* Gastrointestinal problems such as diarrhea, constipation, nausea, vomiting, or abdominal pain
Familial amyloidosis is typically inherited in an autosomal dominant manner, meaning that a child has a 50% chance of inheriting the mutated gene from a parent with the disorder. However, some cases may be due to new (de novo) mutations and occur in people without a family history of the disorder.
Diagnosis of familial amyloidosis typically involves a combination of clinical evaluation, genetic testing, and tissue biopsy to confirm the presence of amyloid fibrils. Treatment may involve medications to manage symptoms, as well as liver transplantation or other experimental therapies aimed at reducing the production of abnormal proteins that form amyloid fibrils.
Amyloid is a term used in medicine to describe abnormally folded protein deposits that can accumulate in various tissues and organs of the body. These misfolded proteins can form aggregates known as amyloid fibrils, which have a characteristic beta-pleated sheet structure. Amyloid deposits can be composed of different types of proteins, depending on the specific disease associated with the deposit.
In some cases, amyloid deposits can cause damage to organs and tissues, leading to various clinical symptoms. Some examples of diseases associated with amyloidosis include Alzheimer's disease (where amyloid-beta protein accumulates in the brain), systemic amyloidosis (where amyloid fibrils deposit in various organs such as the heart, kidneys, and liver), and type 2 diabetes (where amyloid deposits form in the pancreas).
It's important to note that not all amyloid deposits are harmful or associated with disease. However, when they do cause problems, treatment typically involves managing the underlying condition that is leading to the abnormal protein accumulation.
Serum Amyloid A (SAA) protein is an acute phase protein produced primarily in the liver, although it can also be produced by other cells in response to inflammation. It is a member of the apolipoprotein family and is found in high-density lipoproteins (HDL) in the blood. SAA protein levels increase rapidly during the acute phase response to infection, trauma, or tissue damage, making it a useful biomarker for inflammation.
In addition to its role as an acute phase protein, SAA has been implicated in several disease processes, including atherosclerosis and amyloidosis. In amyloidosis, SAA can form insoluble fibrils that deposit in various tissues, leading to organ dysfunction. There are four subtypes of SAA in humans (SAA1, SAA2, SAA3, and SAA4), with SAA1 and SAA2 being the most responsive to inflammatory stimuli.
Prealbumin, also known as transthyretin, is a protein produced primarily in the liver and circulates in the blood. It plays a role in transporting thyroid hormones and vitamin A throughout the body. Prealbumin levels are often used as an indicator of nutritional status and liver function. Low prealbumin levels may suggest malnutrition or inflammation, while increased levels can be seen in certain conditions like hyperthyroidism. It is important to note that prealbumin levels should be interpreted in conjunction with other clinical findings and laboratory tests for a more accurate assessment of a patient's health status.
Immunoglobulin light chains are the smaller protein subunits of an immunoglobulin, also known as an antibody. They are composed of two polypeptide chains, called kappa (κ) and lambda (λ), which are produced by B cells during the immune response. Each immunoglobulin molecule contains either two kappa or two lambda light chains, in association with two heavy chains.
Light chains play a crucial role in the antigen-binding site of an antibody, where they contribute to the specificity and affinity of the interaction between the antibody and its target antigen. In addition to their role in immune function, abnormal production or accumulation of light chains can lead to various diseases, such as multiple myeloma and amyloidosis.
Familial Mediterranean Fever (FMF) is a hereditary inflammatory disorder that primarily affects people of Mediterranean ancestry, including populations from Turkey, Armenia, Arab countries, and Jewish communities from the Middle East. It is caused by mutations in the MEFV gene, which provides instructions for making a protein called pyrin or marenostrin.
The main features of FMF include recurrent episodes of fever, serositis (inflammation of the membranes lining the abdominal cavity, chest cavity, or heart), and polyserositis (inflammation affecting multiple serous membranes simultaneously). The attacks usually last between 12 and 72 hours and can be associated with severe abdominal pain, joint pain, and skin rashes.
The diagnosis of FMF is based on clinical criteria, family history, and genetic testing. Treatment typically involves the use of colchicine, an anti-inflammatory medication that helps prevent attacks and reduces the risk of long-term complications such as amyloidosis, a condition characterized by the buildup of abnormal protein deposits in various organs.
Early diagnosis and treatment of FMF are essential to prevent complications and improve quality of life for affected individuals.
Amyloid neuropathies are a group of peripheral nerve disorders caused by the abnormal accumulation of amyloid proteins in the nerves. Amyloid is a protein that can be produced in various diseases and can deposit in different organs, including nerves. When this occurs in the nerves, it can lead to damage and dysfunction, resulting in symptoms such as numbness, tingling, pain, and weakness in the affected limbs.
There are several types of amyloid neuropathies, with the two most common being:
1. Transthyretin (TTR)-related hereditary amyloidosis: This is an inherited disorder caused by mutations in the TTR gene, which leads to the production of abnormal TTR protein that can form amyloid deposits in various organs, including nerves.
2. Immunoglobulin light chain (AL) amyloidosis: This is a disorder in which abnormal plasma cells produce excessive amounts of immunoglobulin light chains, which can form amyloid deposits in various organs, including nerves.
The diagnosis of amyloid neuropathies typically involves a combination of clinical evaluation, nerve conduction studies, and tissue biopsy to confirm the presence of amyloid deposits. Treatment options depend on the underlying cause of the disorder and may include medications, chemotherapy, stem cell transplantation, or supportive care to manage symptoms.
Congo Red is a synthetic diazo dye that is commonly used in histology and pathology for stainings and tests. It is particularly useful in identifying amyloid deposits in tissues, which are associated with various diseases such as Alzheimer's disease, type 2 diabetes, and systemic amyloidosis.
When Congo Red binds to amyloid fibrils, it exhibits a characteristic apple-green birefringence under polarized light microscopy. Additionally, Congo Red stained amyloid deposits show a shift in their emission spectrum when excited with circularly polarized light, a phenomenon known as dichroism. These properties make Congo Red a valuable tool for the diagnosis and study of amyloidosis and other protein misfolding disorders.
It is important to note that Congo Red staining should be performed with care, as it can be toxic and carcinogenic if not handled properly.
Familial amyloid neuropathies are a group of inherited disorders characterized by the accumulation of abnormal deposits of amyloid proteins in various tissues and organs of the body. These abnormal deposits can cause damage to nerves, leading to a peripheral neuropathy that affects sensation, movement, and organ function.
There are several types of familial amyloid neuropathies, each caused by different genetic mutations. The most common type is known as transthyretin-related hereditary amyloidosis (TTR-HA), which is caused by mutations in the TTR gene. Other types include apolipoprotein A1-related hereditary amyloidosis (APOA1-HA) and gelsolin-related amyloidosis (AGel-HA).
Symptoms of familial amyloid neuropathies can vary depending on the type and severity of the disorder. Common symptoms include:
* Numbness, tingling, or pain in the hands and feet
* Weakness or loss of muscle strength in the legs and arms
* Autonomic nervous system dysfunction, leading to problems with digestion, heart rate, blood pressure, and temperature regulation
* Carpal tunnel syndrome
* Eye abnormalities, such as vitreous opacities or retinal deposits
* Kidney disease
Familial amyloid neuropathies are typically inherited in an autosomal dominant manner, meaning that a child has a 50% chance of inheriting the mutated gene from an affected parent. Diagnosis is usually made through genetic testing and confirmation of the presence of amyloid deposits in tissue samples.
Treatment for familial amyloid neuropathies typically involves managing symptoms and slowing the progression of the disease. This may include medications to control pain, physical therapy to maintain muscle strength and mobility, and devices such as braces or wheelchairs to assist with mobility. In some cases, liver transplantation may be recommended to remove the source of the mutated transthyretin protein.
Cardiomyopathies are a group of diseases that affect the heart muscle, leading to mechanical and/or electrical dysfunction. The American Heart Association (AHA) defines cardiomyopathies as "a heterogeneous group of diseases of the myocardium associated with mechanical and/or electrical dysfunction that usually (but not always) exhibit inappropriate ventricular hypertrophy or dilatation and frequently lead to heart failure."
There are several types of cardiomyopathies, including:
1. Dilated cardiomyopathy (DCM): This is the most common type of cardiomyopathy, characterized by an enlarged left ventricle and impaired systolic function, leading to heart failure.
2. Hypertrophic cardiomyopathy (HCM): In this type, there is abnormal thickening of the heart muscle, particularly in the septum between the two ventricles, which can obstruct blood flow and increase the risk of arrhythmias.
3. Restrictive cardiomyopathy (RCM): This is a rare form of cardiomyopathy characterized by stiffness of the heart muscle, impaired relaxation, and diastolic dysfunction, leading to reduced filling of the ventricles and heart failure.
4. Arrhythmogenic right ventricular cardiomyopathy (ARVC): In this type, there is replacement of the normal heart muscle with fatty or fibrous tissue, primarily affecting the right ventricle, which can lead to arrhythmias and sudden cardiac death.
5. Unclassified cardiomyopathies: These are conditions that do not fit into any of the above categories but still significantly affect the heart muscle and function.
Cardiomyopathies can be caused by genetic factors, acquired conditions (e.g., infections, toxins, or autoimmune disorders), or a combination of both. The diagnosis typically involves a comprehensive evaluation, including medical history, physical examination, electrocardiogram (ECG), echocardiography, cardiac magnetic resonance imaging (MRI), and sometimes genetic testing. Treatment depends on the type and severity of the condition but may include medications, lifestyle modifications, implantable devices, or even heart transplantation in severe cases.
Beta-2 microglobulin (β2M) is a small protein that is a component of the major histocompatibility complex class I molecule, which plays a crucial role in the immune system. It is found on the surface of almost all nucleated cells in the body and is involved in presenting intracellular peptides to T-cells for immune surveillance.
β2M is produced at a relatively constant rate by cells throughout the body and is freely filtered by the glomeruli in the kidneys. Under normal circumstances, most of the filtrated β2M is reabsorbed and catabolized in the proximal tubules of the nephrons. However, when the glomerular filtration rate (GFR) is decreased, as in chronic kidney disease (CKD), the reabsorption capacity of the proximal tubules becomes overwhelmed, leading to increased levels of β2M in the blood and its subsequent appearance in the urine.
Elevated serum and urinary β2M levels have been associated with various clinical conditions, such as CKD, multiple myeloma, autoimmune disorders, and certain infectious diseases. Measuring β2M concentrations can provide valuable information for diagnostic, prognostic, and monitoring purposes in these contexts.
Serum Amyloid P-component (SAP) is a protein that is normally present in the blood and other bodily fluids. It is a part of the larger family of pentraxin proteins, which are involved in the innate immune response, meaning they provide immediate defense against foreign invaders without needing to adapt over time. SAP plays a role in inflammation, immune complex clearance, and complement activation.
In the context of amyloidosis, SAP binds to misfolded proteins called amyloid fibrils, which can deposit in various tissues and organs, leading to their dysfunction and failure. The accumulation of these amyloid fibrils with SAP is a hallmark of systemic amyloidosis.
It's important to note that while SAP plays a role in the pathogenesis of amyloidosis, it is not directly responsible for causing the disease. Instead, its presence can serve as a useful marker for diagnosing and monitoring the progression of amyloidosis.
Nephrotic syndrome is a group of symptoms that indicate kidney damage, specifically damage to the glomeruli—the tiny blood vessel clusters in the kidneys that filter waste and excess fluids from the blood. The main features of nephrotic syndrome are:
1. Proteinuria (excess protein in urine): Large amounts of a protein called albumin leak into the urine due to damaged glomeruli, which can't properly filter proteins. This leads to low levels of albumin in the blood, causing fluid buildup and swelling.
2. Hypoalbuminemia (low blood albumin levels): As albumin leaks into the urine, the concentration of albumin in the blood decreases, leading to hypoalbuminemia. This can cause edema (swelling), particularly in the legs, ankles, and feet.
3. Edema (fluid retention and swelling): With low levels of albumin in the blood, fluids move into the surrounding tissues, causing swelling or puffiness. The swelling is most noticeable around the eyes, face, hands, feet, and abdomen.
4. Hyperlipidemia (high lipid/cholesterol levels): The kidneys play a role in regulating lipid metabolism. Damage to the glomeruli can lead to increased lipid production and high cholesterol levels in the blood.
Nephrotic syndrome can result from various underlying kidney diseases, such as minimal change disease, membranous nephropathy, or focal segmental glomerulosclerosis. Treatment depends on the underlying cause and may include medications to control inflammation, manage high blood pressure, and reduce proteinuria. In some cases, dietary modifications and lifestyle changes are also recommended.
Paraproteinemias refer to the presence of abnormal levels of paraproteins in the blood. Paraproteins are immunoglobulins (antibodies) produced by plasma cells, which are a type of white blood cell found in the bone marrow. In healthy individuals, paraproteins play a role in the immune system's response to infection and disease. However, in certain conditions, such as multiple myeloma, monoclonal gammopathy of undetermined significance (MGUS), and Waldenstrom macroglobulinemia, plasma cells produce excessive amounts of a single type of paraprotein, leading to its accumulation in the blood.
Paraproteinemias can cause various symptoms depending on the level of paraproteins present and their impact on organs and tissues. These symptoms may include fatigue, weakness, numbness or tingling in the extremities, bone pain, recurrent infections, and kidney problems. In some cases, paraproteinemias may not cause any symptoms and may only be detected during routine blood tests.
It is important to note that while paraproteinemias are often associated with plasma cell disorders, they can also occur in other conditions such as chronic inflammation or autoimmune diseases. Therefore, further testing and evaluation are necessary to determine the underlying cause of paraproteinemia and develop an appropriate treatment plan.
Tracheal diseases refer to a group of medical conditions that affect the trachea, also known as the windpipe. The trachea is a tube-like structure made up of rings of cartilage and smooth muscle, which extends from the larynx (voice box) to the bronchi (airways leading to the lungs). Its primary function is to allow the passage of air to and from the lungs.
Tracheal diseases can be categorized into several types, including:
1. Tracheitis: Inflammation of the trachea, often caused by viral or bacterial infections.
2. Tracheal stenosis: Narrowing of the trachea due to scarring, inflammation, or compression from nearby structures such as tumors or goiters.
3. Tracheomalacia: Weakening and collapse of the tracheal walls, often seen in newborns and young children but can also occur in adults due to factors like chronic cough, aging, or connective tissue disorders.
4. Tracheoesophageal fistula: An abnormal connection between the trachea and the esophagus, which can lead to respiratory complications and difficulty swallowing.
5. Tracheal tumors: Benign or malignant growths that develop within the trachea, obstructing airflow and potentially leading to more severe respiratory issues.
6. Tracheobronchial injury: Damage to the trachea and bronchi, often caused by trauma such as blunt force or penetrating injuries.
7. Congenital tracheal abnormalities: Structural defects present at birth, including complete tracheal rings, which can cause narrowing or collapse of the airway.
Symptoms of tracheal diseases may include cough, wheezing, shortness of breath, chest pain, and difficulty swallowing. Treatment options depend on the specific condition and its severity but may involve medications, surgery, or other interventions to alleviate symptoms and improve respiratory function.
Kidney disease, also known as nephropathy or renal disease, refers to any functional or structural damage to the kidneys that impairs their ability to filter blood, regulate electrolytes, produce hormones, and maintain fluid balance. This damage can result from a wide range of causes, including diabetes, hypertension, glomerulonephritis, polycystic kidney disease, lupus, infections, drugs, toxins, and congenital or inherited disorders.
Depending on the severity and progression of the kidney damage, kidney diseases can be classified into two main categories: acute kidney injury (AKI) and chronic kidney disease (CKD). AKI is a sudden and often reversible loss of kidney function that occurs over hours to days, while CKD is a progressive and irreversible decline in kidney function that develops over months or years.
Symptoms of kidney diseases may include edema, proteinuria, hematuria, hypertension, electrolyte imbalances, metabolic acidosis, anemia, and decreased urine output. Treatment options depend on the underlying cause and severity of the disease and may include medications, dietary modifications, dialysis, or kidney transplantation.
Macroglossia is a medical term that refers to an abnormally large tongue in relation to the size of the oral cavity. It can result from various conditions, including certain genetic disorders (such as Down syndrome and Beckwith-Wiedemann syndrome), hormonal disorders (such as acromegaly), inflammatory diseases (such as amyloidosis), tumors or growths on the tongue, or neurological conditions. Macroglossia can cause difficulties with speaking, swallowing, and breathing, particularly during sleep. Treatment depends on the underlying cause but may include corticosteroids, radiation therapy, surgery, or a combination of these approaches.
Amyloidogenic proteins are misfolded proteins that can form amyloid fibrils, which are insoluble protein aggregates with a characteristic cross-beta sheet quaternary structure. These amyloid fibrils can accumulate in various tissues and organs, leading to the formation of amyloid deposits. The accumulation of amyloidogenic proteins and the resulting amyloid deposits have been associated with several neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and Huntington's disease, as well as systemic amyloidoses.
In Alzheimer's disease, for example, the amyloidogenic protein is beta-amyloid, which is produced from the proteolytic processing of the amyloid precursor protein (APP). In Parkinson's disease, the amyloidogenic protein is alpha-synuclein, which forms the main component of Lewy bodies.
It's important to note that not all misfolded proteins are necessarily amyloidogenic, and not all amyloid fibrils are associated with disease. Some amyloid fibrils can have functional roles in normal physiological processes.
Melphalan is an antineoplastic agent, specifically an alkylating agent. It is used in the treatment of multiple myeloma and other types of cancer. The medical definition of Melphalan is:
A nitrogen mustard derivative that is used as an alkylating agent in the treatment of cancer, particularly multiple myeloma and ovarian cancer. Melphalan works by forming covalent bonds with DNA, resulting in cross-linking of the double helix and inhibition of DNA replication and transcription. This ultimately leads to cell cycle arrest and apoptosis (programmed cell death) in rapidly dividing cells, such as cancer cells.
Melphalan is administered orally or intravenously, and its use is often accompanied by other anticancer therapies, such as radiation therapy or chemotherapy. Common side effects of Melphalan include nausea, vomiting, diarrhea, and bone marrow suppression, which can lead to anemia, neutropenia, and thrombocytopenia. Other potential side effects include hair loss, mucositis, and secondary malignancies.
It is important to note that Melphalan should be used under the close supervision of a healthcare professional, as it can cause serious adverse reactions if not administered correctly.
Bence Jones protein is a type of immunoglobulin light chain that can be detected in the urine or blood of some patients with certain diseases, most notably multiple myeloma. It's named after Henry Bence Jones, a 19th-century English physician who first described it.
These proteins are produced by malignant plasma cells, which are a type of white blood cell found in the bone marrow. In multiple myeloma, these cancerous cells multiply and produce abnormal amounts of immunoglobulins, leading to the overproduction of Bence Jones proteins.
When these proteins are excreted in the urine, they can cause damage to the kidneys, leading to kidney dysfunction or failure. Therefore, the detection of Bence Jones protein in the urine can be a sign of multiple myeloma or other related diseases. However, it's important to note that not all patients with multiple myeloma will have Bence Jones proteins in their urine.
A biopsy is a medical procedure in which a small sample of tissue is taken from the body to be examined under a microscope for the presence of disease. This can help doctors diagnose and monitor various medical conditions, such as cancer, infections, or autoimmune disorders. The type of biopsy performed will depend on the location and nature of the suspected condition. Some common types of biopsies include:
1. Incisional biopsy: In this procedure, a surgeon removes a piece of tissue from an abnormal area using a scalpel or other surgical instrument. This type of biopsy is often used when the lesion is too large to be removed entirely during the initial biopsy.
2. Excisional biopsy: An excisional biopsy involves removing the entire abnormal area, along with a margin of healthy tissue surrounding it. This technique is typically employed for smaller lesions or when cancer is suspected.
3. Needle biopsy: A needle biopsy uses a thin, hollow needle to extract cells or fluid from the body. There are two main types of needle biopsies: fine-needle aspiration (FNA) and core needle biopsy. FNA extracts loose cells, while a core needle biopsy removes a small piece of tissue.
4. Punch biopsy: In a punch biopsy, a round, sharp tool is used to remove a small cylindrical sample of skin tissue. This type of biopsy is often used for evaluating rashes or other skin abnormalities.
5. Shave biopsy: During a shave biopsy, a thin slice of tissue is removed from the surface of the skin using a sharp razor-like instrument. This technique is typically used for superficial lesions or growths on the skin.
After the biopsy sample has been collected, it is sent to a laboratory where a pathologist will examine the tissue under a microscope and provide a diagnosis based on their findings. The results of the biopsy can help guide further treatment decisions and determine the best course of action for managing the patient's condition.
"Acinonyx" is a genus name that refers to a single species of big cat, the cheetah. The correct medical definition of "Acinonyx" is:
* Acinonyx jubatus: a large, slender wild cat that is known for its incredible speed and unique adaptations for running. It is the fastest land animal, capable of reaching speeds up to 60-70 miles per hour. The cheetah's body is built for speed, with long legs, a flexible spine, and a non-retractable claw that provides traction while running.
The cheetah's habitat ranges from the savannas of Africa to the deserts of Iran. It primarily hunts medium-sized ungulates, such as gazelles and wildebeest. The cheetah's population has been declining due to habitat loss, human-wildlife conflict, and illegal wildlife trade. Conservation efforts are underway to protect this iconic species and its habitat.
Immunoglobulin lambda-chains (Igλ) are one type of light chain found in the immunoglobulins, also known as antibodies. Antibodies are proteins that play a crucial role in the immune system's response to foreign substances, such as bacteria and viruses.
Immunoglobulins are composed of two heavy chains and two light chains, which are interconnected by disulfide bonds. There are two types of light chains: kappa (κ) and lambda (λ). Igλ chains are one type of light chain that can be found in association with heavy chains to form functional antibodies.
Igλ chains contain a variable region, which is responsible for recognizing and binding to specific antigens, and a constant region, which determines the class of the immunoglobulin (e.g., IgA, IgD, IgE, IgG, or IgM).
In humans, approximately 60% of all antibodies contain Igλ chains, while the remaining 40% contain Igκ chains. The ratio of Igλ to Igκ chains can vary depending on the type of immunoglobulin and its function in the immune response.
Gelsolin is a protein that plays a role in the regulation of actin, which is a major component of the cytoskeleton in cells. The gelsolin protein can bind to and sever actin filaments, as well as cap their plus ends, preventing further growth. This regulation of actin dynamics is important for various cellular processes, including cell motility, wound healing, and the immune response.
There are two forms of gelsolin in humans: plasma gelsolin, which is found in blood plasma, and cytoplasmic gelsolin, which is found in the cytoplasm of cells. Plasma gelsolin has been shown to have anti-inflammatory properties and may play a role in protecting against sepsis and other inflammatory conditions.
Mutations in the gene that encodes gelsolin can lead to various genetic disorders, including familial amyloidosis, Finnish type (FAF), which is characterized by progressive nerve damage and muscle weakness.
Factor X deficiency, also known as Stuart-Prower factor deficiency, is a rare bleeding disorder that affects the body's ability to form blood clots. It is caused by a mutation in the gene that provides instructions for making coagulation factor X, a protein involved in the coagulation cascade, which is a series of chemical reactions that lead to the formation of a blood clot.
People with factor X deficiency may experience excessive bleeding after injury or surgery, and they may also have an increased risk of spontaneous bleeding, such as nosebleeds, heavy menstrual periods, and joint bleeds. The severity of the condition can vary widely, from mild to severe, depending on the level of factor X activity in the blood.
Factor X deficiency can be inherited or acquired. Inherited forms of the disorder are caused by mutations in the F10 gene and are usually present at birth. Acquired forms of the disorder can develop later in life due to conditions such as liver disease, vitamin K deficiency, or the use of certain medications that interfere with coagulation.
Treatment for factor X deficiency typically involves replacement therapy with fresh frozen plasma or recombinant factor X concentrates to help restore normal clotting function. In some cases, other treatments such as antifibrinolytic agents or desmopressin may also be used to manage bleeding symptoms.
Genetic skin diseases are a group of disorders caused by mutations or alterations in the genetic material (DNA), which can be inherited from one or both parents. These mutations affect the structure, function, or development of the skin and can lead to various conditions with different symptoms, severity, and prognosis.
Some examples of genetic skin diseases include:
1. Epidermolysis Bullosa (EB): A group of disorders characterized by fragile skin and mucous membranes that blister and tear easily, leading to painful sores and wounds. There are several types of EB, each caused by mutations in different genes involved in anchoring the epidermis to the dermis.
2. Ichthyosis: A family of genetic disorders characterized by dry, thickened, scaly, or rough skin. The severity and symptoms can vary widely, depending on the specific type and underlying genetic cause.
3. Neurofibromatosis: A group of conditions caused by mutations in the NF1 gene, which regulates cell growth and division. The most common types, NF1 and NF2, are characterized by the development of benign tumors called neurofibromas on the skin and nerves, as well as other symptoms affecting various organs and systems.
4. Tuberous Sclerosis Complex (TSC): A genetic disorder caused by mutations in the TSC1 or TSC2 genes, which control cell growth and division. TSC is characterized by the development of benign tumors in multiple organs, including the skin, brain, heart, kidneys, and lungs.
5. Xeroderma Pigmentosum (XP): A rare genetic disorder caused by mutations in genes responsible for repairing DNA damage from ultraviolet (UV) radiation. People with XP are extremely sensitive to sunlight and have a high risk of developing skin cancer and other complications.
6. Incontinentia Pigmenti (IP): A genetic disorder that affects the development and growth of skin, hair, nails, teeth, and eyes. IP is caused by mutations in the IKBKG gene and primarily affects females.
7. Darier's Disease: An inherited skin disorder characterized by greasy, crusted, keratotic papules and plaques, usually located on the trunk, scalp, and seborrheic areas of the body. Darier's disease is caused by mutations in the ATP2A2 gene.
These are just a few examples of genetic skin disorders. There are many more, each with its unique set of symptoms, causes, and treatments. If you or someone you know has a genetic skin disorder, it is essential to consult with a dermatologist or other healthcare professional for proper diagnosis and treatment.
A fatal outcome is a term used in medical context to describe a situation where a disease, injury, or illness results in the death of an individual. It is the most severe and unfortunate possible outcome of any medical condition, and is often used as a measure of the severity and prognosis of various diseases and injuries. In clinical trials and research, fatal outcome may be used as an endpoint to evaluate the effectiveness and safety of different treatments or interventions.
Multiple myeloma is a type of cancer that forms in a type of white blood cell called a plasma cell. Plasma cells help your body fight infection by producing antibodies. In multiple myeloma, cancerous plasma cells accumulate in the bone marrow and crowd out healthy blood cells. Rather than producing useful antibodies, the cancer cells produce abnormal proteins that can cause complications such as kidney damage, bone pain and fractures.
Multiple myeloma is a type of cancer called a plasma cell neoplasm. Plasma cell neoplasms are diseases in which there is an overproduction of a single clone of plasma cells. In multiple myeloma, this results in the crowding out of normal plasma cells, red and white blood cells and platelets, leading to many of the complications associated with the disease.
The abnormal proteins produced by the cancer cells can also cause damage to organs and tissues in the body. These abnormal proteins can be detected in the blood or urine and are often used to monitor the progression of multiple myeloma.
Multiple myeloma is a relatively uncommon cancer, but it is the second most common blood cancer after non-Hodgkin lymphoma. It typically occurs in people over the age of 65, and men are more likely to develop multiple myeloma than women. While there is no cure for multiple myeloma, treatments such as chemotherapy, radiation therapy, and stem cell transplantation can help manage the disease and its symptoms, and improve quality of life.
