  • CD23 was positive in 16% of the cases (all CD5 negative and all CD40 positive). (aacrjournals.org)
  • CD23 and CD40 expression seems to be prognostically favorable in DLBCL. (aacrjournals.org)
  • De plus, nos résultats montrent pour la première fois une implication du CD40 homodimère dans l'induction du CD23 par le biais du TLR4. (umontreal.ca)
  • Therefore, the first conditional rule for ICT response is the successful MHC-dependent presentation of tumour antigen in the format of peptides to T-cell receptors (TCR), which results in the generation of a clonally expanded population of anti-tumour effector lymphocytes, as shown in the wheel diagram of Fig. 1 (orange, Stages 1-3). (nature.com)
  • In humans, the MHC is called the human leukocyte antigen (HLA) system and is located on the short arm of chromosome 6, near the complement genes. (medscape.com)
  • Polymorphisms of the genes CTLA4, PTPN22, CD40, and PPARG and their roles in Graves' disease: susceptibility and clinical features. (cdc.gov)
  • Early reports dubbed increases in B cell antigen sensitivity a "neuraminidase effect," ( Cowing and Chapdelaine, 1983 ) and recent evidence has ascribed this phenomenon to sialic acid acting as a negative regulator of immune cell interactions ( Bagriacik and Miller, 1999 ). (frontiersin.org)
  • This assay has high sensitivity and excellent specificity for detection of human CD40/TNFRSF5. (assaysolution.com)
  • The expression of CD40 is diverse. (wikipedia.org)
  • AT-hook transcription factor AKNA is reported to coordinately regulate the expression of CD40, which may be important for homotypic cell interactions. (thermofisher.com)
  • CD40 expression correlated with bax but not with bcl -2 expression. (aacrjournals.org)
  • Expression of both CD40 and CD27 was found to be significantly higher in low- than in high-risk patients as defined by standard clinical risk parameters such as age and white blood cell count. (eur.nl)
  • Of note, high CD40 expression particularly protected against late relapse. (eur.nl)
  • Thus very high expression of CD40 on BCP-ALL blasts is an independent prognostic marker indicative of superior relapse-free survival that may in part be due to CD40- dependent death receptor up-regulation. (eur.nl)
  • Cyclosporin A inhibits CD40 ligand expression in T lymphocytes. (bdbiosciences.com)
  • Expression of JC virus T-Antigen in a multiple sclerosis patient with a Glioblastoma multiforme. (lsuhsc.edu)
  • In the presence of the surface antigen, higher doses of NP resulted in the up-regulated expression of IFN-α, suggesting a robust anti-viral effect (Supplementary Fig. (enlibio.com)
  • Additionally, CD40 is important for T cell-B cell interactions. (biolegend.com)
  • The meeting was organized into 7 sessions on such topics as genetic and cellular mechanisms of carbohydrate immunity, carbohydrate antigens for vaccines, and new tools for studying carbohydrates. (cdc.gov)
  • ELISA: Human CD40/TNFRSF5 ELISA Kit (Colorimetric) - These standard curves are provided for demonstration only. (assaysolution.com)
  • The results obtained demonstrate the benefits of this strategy owing to the small quantity of antigens required to activate the immune system, with or without an adjuvant, and its ability to trigger a lasting cellular and humoral and immune response. (businesswire.com)
  • No significant cross-reactivity or interference between human CD40/TNFRSF5 and analogues was observed. (assaysolution.com)
  • CD40 Ligand has been shown to induce cytokine production and tumoricidal activity in peripheral blood monocytes. (thermofisher.com)
  • Upon antigen stimulation they rapidly upregulate glycolysis and oxygen to produce high levels of ATP and nucleotides required for cell proliferation and effector functions. (nih.gov)
  • The remaining member of TRAF4 family, namely TRAF4, positively regulates CD40 signalling, but interacts with CD40 indirectly. (wikipedia.org)
