Molecular cloning and epitope analysis of the peanut allergen Ara h 3. (1/860)
Peanut allergy is a significant IgE-mediated health problem because of the increased prevalence, potential severity, and chronicity of the reaction. Following our characterization of the two peanut allergens Ara h 1 and Ara h 2, we have isolated a cDNA clone encoding a third peanut allergen, Ara h 3. The deduced amino acid sequence of Ara h 3 shows homology to 11S seed-storage proteins. The recombinant form of this protein was expressed in a bacterial system and was recognized by serum IgE from approximately 45% of our peanut-allergic patient population. Serum IgE from these patients and overlapping, synthetic peptides were used to map the linear, IgE-binding epitopes of Ara h 3. Four epitopes, between 10 and 15 amino acids in length, were found within the primary sequence, with no obvious sequence motif shared by the peptides. One epitope is recognized by all Ara h 3-allergic patients. Mutational analysis of the epitopes revealed that single amino acid changes within these peptides could lead to a reduction or loss of IgE binding. By determining which amino acids are critical for IgE binding, it might be possible to alter the Ara h 3 cDNA to encode a protein with a reduced IgE-binding capacity. These results will enable the design of improved diagnostic and therapeutic approaches for food-hypersensitivity reactions. (+info)Involvement of tachykinin receptors in sensitisation to cow's milk proteins in guinea pigs. (2/860)
BACKGROUND: There is growing evidence for a pivotal role for tachykinins in gut neuroimmune interactions. AIMS: To determine whether NK1, NK2, and NK3 tachykinin receptors are involved in milk protein induced allergic sensitisation. METHODS: Eight groups of 12 Dunkin-Hartley guinea pigs (250-300 g) were used. Four groups were sensitised to milk proteins for three weeks. During this period, these animals were injected intraperitoneally each day with NK1 (SR 140333; 0.3 mg/kg), NK2 (SR 48968; 5 mg/kg), or NK3 (SR 142801; 5 mg/kg) receptor antagonist or vehicle. The fifth group had water available instead of milk and was used as a non-sensitised control. The three other groups received the NK receptor antagonists for three weeks but were not sensitised to milk proteins. RESULTS: Sensitised animals treated with NK1 and NK3 receptor antagonists had both lower IgE and IgG serum titres, evaluated by passive cutaneous anaphylaxis, and lower specific IgG serum titres, determined by enzyme linked immunosorbent assay (ELISA), than vehicle treated animals. Sensitisation induced an increase in intestinal mast cell number which was abolished by treatment with the NK1 receptor antagonist. Antigenic challenge-induced jejunal hypersecretion was also blocked by treatment with the NK1 receptor antagonist. CONCLUSION: In guinea pigs, NK1 and NK3 but not NK2 receptors are involved in sensitisation to cow's milk. However, NK1 but not NK3 receptor antagonists abolish both the hypermastocytosis induced by food allergy and the hypersecretion induced by antigenic challenge, suggesting different roles for NK1 and NK3 receptors in the mechanisms of sensitisation to beta-lactoglobulin. (+info)Dental surgeons with natural rubber latex allergy: a report of 20 cases. (3/860)
Latex allergy is becoming a major occupational health issue and dental surgeons are at risk from becoming sensitized to natural rubber latex. A study was conducted to investigate risk factors and glove-related symptoms reported by dentists with natural rubber latex allergy. Twenty dentists, who had undergone serological or dermatological testing for a Type I allergy to latex, were identified from a questionnaire survey. Risk factors investigated were: gender, years in clinical practice, exposure to latex gloves, atopic history and food allergy. The majority of dentists (75%) gave an atopic history. Glove-related adverse reactions ranged from cutaneous to systemic manifestations. All twenty dentists reported itching of the hands in response to latex gloves. One respondent was unable to continue in dental practice because of her glove-related allergies; nineteen dentists were able to continue by using synthetic, non-latex gloves. (+info)Acute liver injury that followed food-dependent exercise-induced anaphylaxis. (4/860)
We describe an unusual case of acute liver injury that followed food-dependent exercise-induced anaphylaxis (FDEIAn). A 45-year-old man who experienced anaphylactic shock induced by postprandial exercise and took alcohol that night was admitted the following day to our hospital because of general fatigue. Laboratory examinations revealed elevated hepatic enzymes (aspartate aminotransferase (AST) 6,110 IU, alanine aminotransferase (ALT) 4,178 IU). He had two similar episodes in the past. We speculated that acute liver injury in this case might be induced by interaction of anaphylactic shock and alcohol. (+info)Allergen mimotopes in food enhance type I allergic reactions in mice. (5/860)
BIP1is a murine IgG antibody capable of enhancing the IgE binding to Bet v 1, the major birch pollen allergen. We have previously generated a mimotope of BIP1, designated Bet mim 1, from a constrained phage display peptide library. We demonstrated that oral immunization of BALB/c mice with the Bet mim 1 mimotope resulted in the induction of Bet v 1-specific IgG. The aim of this study was to test the influence of such an oral immunization with Bet mim 1 on a subsequent type I allergic response to Bet v 1. Phages displaying Bet mim 1 or control mimotopes, or PBS alone, were delivered to BALB/c mice by intragastric gavages prior to systemic sensitization with recombinant Bet v 1 and Al(OH)(3), an adjuvant inducing preferentially IgE antibody responses. Only mice fed with Bet mim 1-phages displayed substantially enhanced type I allergic skin reactivity to Bet v 1, as compared to mice pretreated with control mimotopes or PBS. A gastric digestion assay indicated that Bet v 1 and its homologue from apple, Mal d 1, were degraded within seconds under physiological conditions. In contrast, phage-displayed mimotopes were resistant to digestion. Our data indicate that allergen mimics in the diet that resist digestion, can induce allergen specific IgG able to enhance an allergic response. We therefore conclude that sensitization via the oral route may represent a mechanism for aggravating type I allergic reactions, probably leading to an earlier onset of symptoms even at lower allergen dosage. (+info)Characterisation of immune mediator release during the immediate response to segmental mucosal challenge in the jejunum of patients with food allergy. (6/860)
BACKGROUND: Food allergy is a common complaint among patients with a broad spectrum of abdominal and extra-abdominal symptoms that must be distinguished from other more common non-immunological food intolerances. AIMS: To investigate whether human intestinal hypersensitivity reactions are associated with detectable release of inflammatory mediators from activated cells, which may serve as a biological marker of true allergic reactions. PATIENTS/METHODS: In eight patients with food allergy and seven healthy volunteers, a closed-segment perfusion technique was used to investigate the effects of jejunal food challenge on luminal release of tryptase, histamine, prostaglandin D(2), eosinophil cationic protein, peroxidase activity, and water flux. RESULTS: Intraluminal administration of food antigens induced a rapid increase in intestinal release of tryptase, histamine, prostaglandin D(2), and peroxidase activity (p<0.05 v basal period) but not eosinophil cationic protein. The increased release of these mediators was associated with a notable water secretory response. CONCLUSIONS: These results suggest that human intestinal hypersensitivity reactions are characterised by prompt activation of mast cells and other immune cells, with notable and immediate secretion of water and inflammatory mediators into the intestinal lumen. Analysis of the profile of markers released into the jejunum after food provocation may be useful for the objective diagnosis of food allergy. (+info)Characterization of a core alpha1-->3-fucosyltransferase from the snail Lymnaea stagnalis that is involved in the synthesis of complex-type N-glycans. (7/860)
We have identified a core alpha1-->3-fucosyltransferase activity in the albumin and prostate glands of the snail Lymnaea stagnalis. Incubation of albumin gland extracts with GDP-[(14)C]Fuc and asialo/agalacto-glycopeptides from human fibrinogen resulted in a labeled product in 50% yield. Analysis of the product by 400 MHz (1)H-NMR spectroscopy showed the presence of a Fuc residue alpha1-->3-linked to the Asn-linked GlcNAc. Therefore, the enzyme can be identified as a GDP-Fuc:GlcNAc (Asn-linked) alpha1-->3-fucosyltransferase. The enzyme acts efficiently on asialo/agalacto-glycopeptides from both human fibrinogen and core alpha1-->6-fucosylated human IgG, whereas bisected asialo/agalacto-glycopeptide could not serve as an acceptor. We propose that the enzyme functions in the synthesis of core alpha1-->3-fucosylated complex-type glycans in L. stagnalis. Core alpha1-->3-fucosylation of the asparagine-linked GlcNAc of plant- and insect-derived glycoproteins is often associated with the allergenicity of such glycoproteins. Since allergic reactions have been reported after consumption of snails, the demonstration of core alpha1-->3-fucosylation in L. stagnalis may be clinically relevant. (+info)Alternative treatments for rheumatoid arthritis. (8/860)
Conventional treatments for rheumatoid arthritis (RA) present a number of problems, in terms of both safety and efficacy. A number of different alternative therapies have been studied, including dietary modifications, nutritional supplements, botanicals, and antibiotics. While the response to these treatments is variable and often unpredictable, some patients have shown dramatic improvement or even complete and long-lasting remission. Moreover, alternative therapies, with the exception of antibiotics, have a low incidence of adverse effects. Consideration of these treatment options has the potential to benefit many patients with RA. (+info)Food hypersensitivity is an umbrella term that encompasses both immunologic and non-immunologic adverse reactions to food. It is also known as "food allergy" or "food intolerance." Food hypersensitivity occurs when the body's immune system or digestive system reacts negatively to a particular food or food component.
Immunologic food hypersensitivity, commonly referred to as a food allergy, involves an immune response mediated by immunoglobulin E (IgE) antibodies. Upon ingestion of the offending food, IgE antibodies bind to the food antigens and trigger the release of histamine and other chemical mediators from mast cells and basophils, leading to symptoms such as hives, swelling, itching, difficulty breathing, or anaphylaxis.
Non-immunologic food hypersensitivity, on the other hand, does not involve the immune system. Instead, it is caused by various mechanisms, including enzyme deficiencies, pharmacological reactions, and metabolic disorders. Examples of non-immunologic food hypersensitivities include lactose intolerance, gluten sensitivity, and histamine intolerance.
It's important to note that the term "food hypersensitivity" is often used interchangeably with "food allergy," but it has a broader definition that includes both immunologic and non-immunologic reactions.
Medical definitions for "milk hypersensitivity" include:
1. The American Academy of Allergy, Asthma & Immunology (AAAAI) defines milk hypersensitivity as an abnormal immune response to one or more proteins found in cow's milk. This reaction can be either an immediate immunoglobulin E (IgE)-mediated allergy or a non-IgE-mediated cow's milk protein intolerance (CMPI).
2. According to the American Academy of Pediatrics (AAP), milk hypersensitivity is an adverse reaction to milk proteins, which can be either an immunoglobulin E (IgE)-mediated allergy or a non-IgE-mediated immune response, causing gastrointestinal symptoms.
3. The Merck Manual defines milk hypersensitivity as an abnormal reaction to one or more proteins in cow's milk, which can manifest as immediate IgE-mediated allergic reactions or delayed non-IgE-mediated reactions, causing various gastrointestinal and skin symptoms.
In summary, milk hypersensitivity is a broad term that encompasses both immune-mediated allergic reactions (IgE and non-IgE) to cow's milk proteins, leading to various clinical manifestations affecting the gastrointestinal system, skin, or respiratory tract.
Immunoglobulin E (IgE) is a type of antibody that plays a key role in the immune response to parasitic infections and allergies. It is produced by B cells in response to stimulation by antigens, such as pollen, pet dander, or certain foods. Once produced, IgE binds to receptors on the surface of mast cells and basophils, which are immune cells found in tissues and blood respectively. When an individual with IgE antibodies encounters the allergen again, the cross-linking of IgE molecules bound to the FcεRI receptor triggers the release of mediators such as histamine, leukotrienes, prostaglandins, and various cytokines from these cells. These mediators cause the symptoms of an allergic reaction, such as itching, swelling, and redness. IgE also plays a role in protecting against certain parasitic infections by activating eosinophils, which can kill the parasites.
In summary, Immunoglobulin E (IgE) is a type of antibody that plays a crucial role in the immune response to allergens and parasitic infections, it binds to receptors on the surface of mast cells and basophils, when an individual with IgE antibodies encounters the allergen again, it triggers the release of mediators from these cells causing the symptoms of an allergic reaction.
Delayed hypersensitivity, also known as type IV hypersensitivity, is a type of immune response that takes place several hours to days after exposure to an antigen. It is characterized by the activation of T cells (a type of white blood cell) and the release of various chemical mediators, leading to inflammation and tissue damage. This reaction is typically associated with chronic inflammatory diseases, such as contact dermatitis, granulomatous disorders (e.g. tuberculosis), and certain autoimmune diseases.
The reaction process involves the following steps:
1. Sensitization: The first time an individual is exposed to an antigen, T cells are activated and become sensitized to it. This process can take several days.
2. Memory: Some of the activated T cells differentiate into memory T cells, which remain in the body and are ready to respond quickly if the same antigen is encountered again.
3. Effector phase: Upon subsequent exposure to the antigen, the memory T cells become activated and release cytokines, which recruit other immune cells (e.g. macrophages) to the site of inflammation. These cells cause tissue damage through various mechanisms, such as phagocytosis, degranulation, and the release of reactive oxygen species.
4. Chronic inflammation: The ongoing immune response can lead to chronic inflammation, which may result in tissue destruction and fibrosis (scarring).
Examples of conditions associated with delayed hypersensitivity include:
* Contact dermatitis (e.g. poison ivy, nickel allergy)
* Tuberculosis
* Leprosy
* Sarcoidosis
* Rheumatoid arthritis
* Type 1 diabetes mellitus
* Multiple sclerosis
* Inflammatory bowel disease (e.g. Crohn's disease, ulcerative colitis)
Drug hypersensitivity is an abnormal immune response to a medication or its metabolites. It is a type of adverse drug reaction that occurs in susceptible individuals, characterized by the activation of the immune system leading to inflammation and tissue damage. This reaction can range from mild symptoms such as skin rashes, hives, and itching to more severe reactions like anaphylaxis, which can be life-threatening.
Drug hypersensitivity reactions can be classified into two main types: immediate (or IgE-mediated) and delayed (or non-IgE-mediated). Immediate reactions occur within minutes to a few hours after taking the medication and are mediated by the release of histamine and other inflammatory mediators from mast cells and basophils. Delayed reactions, on the other hand, can take several days to develop and are caused by T-cell activation and subsequent cytokine release.
Common drugs that can cause hypersensitivity reactions include antibiotics (such as penicillins and sulfonamides), nonsteroidal anti-inflammatory drugs (NSAIDs), monoclonal antibodies, and chemotherapeutic agents. It is important to note that previous exposure to a medication does not always guarantee the development of hypersensitivity reactions, as they can also occur after the first administration in some cases.
The diagnosis of drug hypersensitivity involves a thorough medical history, physical examination, and sometimes skin or laboratory tests. Treatment typically includes avoiding the offending medication and managing symptoms with antihistamines, corticosteroids, or other medications as needed. In severe cases, emergency medical care may be required to treat anaphylaxis or other life-threatening reactions.
A medical definition of 'food' would be:
"Substances consumed by living organisms, usually in the form of meals, which contain necessary nutrients such as carbohydrates, proteins, fats, vitamins, minerals, and water. These substances are broken down during digestion to provide energy, build and repair tissues, and regulate bodily functions."
It's important to note that while this is a medical definition, it also aligns with common understanding of what food is.
"Hate" is not a medical term. In a psychological or emotional context, hate can be described as an intense or passionate dislike, hostility, or prejudice against something or someone. It can lead to negative emotions, behaviors, and attitudes that can have serious consequences for both physical and mental health. Chronic hatred can contribute to stress, anxiety, depression, and even cardiovascular disease. However, it is not a medical diagnosis or condition.
I'm sorry for any confusion, but "Social Media" is a term related to communication technologies, particularly websites and applications that enable users to create and share content or to participate in social networking. It is not a medical concept or term, and therefore, it does not have a medical definition. If you have any questions about medical terms or concepts, I'd be happy to help with those!
In psychology, the term "ego" is used to describe a part of the personality that deals with the conscious mind and includes the senses of self and reality. It is one of the three components of Freud's structural model of the psyche, along with the id and the superego. The ego serves as the mediator between the unconscious desires of the id and the demands of the real world, helping to shape behavior that is socially acceptable and adaptive.
It's important to note that this definition of "ego" is specific to the field of psychology and should not be confused with other uses of the term in different contexts, such as its use in popular culture to refer to an inflated sense of self-importance or self-centeredness.
I am not a medical professional, but I can tell you that there is no specific medical definition for "blogging." Blogging is a general term used to describe the act of creating and maintaining a blog or weblog. A blog is a website that contains regularly updated entries, typically written in an informal or conversational style.
Blogging has become a popular way for people to share their thoughts, experiences, and expertise on various topics, including health and wellness. Some healthcare professionals also use blogs as a platform to provide medical information, advice, and updates to their patients and the general public. However, it is essential to note that any medical information obtained from blogs should not replace professional medical advice, diagnosis, or treatment.
To my knowledge, there is no widely accepted medical definition for "social networking." However, in the context of public health and medicine, social networking often refers to the use of online platforms or tools that allow users to create and maintain virtual connections with others, share information and resources, and participate in interactive communication. These activities can have various impacts on individuals' health behaviors, attitudes, and outcomes, as well as broader population health.
"Animals, Zoo" is not a medical term. However, it generally refers to a collection of various species of wild animals kept in enclosures or exhibits for the public to view and learn about. These animals are usually obtained from different parts of the world and live in environments that attempt to simulate their natural habitats. Zoos play an essential role in conservation efforts, education, and research. They provide a unique opportunity for people to connect with wildlife and understand the importance of preserving and protecting endangered species and their ecosystems.
I'm sorry for any confusion, but "universities" is a term that refers to institutions of higher education and research, and it is not a medical term. A university typically offers undergraduate and postgraduate programs leading to the award of degrees such as bachelor's, master's, and doctoral degrees.
If you have any questions related to medicine or healthcare, I would be happy to try to help answer them for you.
