WebFeb 15, 2004 · In particular, in lymphocytes it has been well documented that MHC class II molecules serve as signal-transducing receptors. MHC class II molecules can transduce signals via their cytoplasmic tails into activated T lymphocytes, which results in protein kinase C (PKC) membrane translocation and inositol phosphate (IP) accumulation. WebThe effect of nicotinamide on the cytokine-induced MHC class II expression and pancreatic beta-cell death was also studied. Methods: Immunocytochemistry, flow cytometry and RNase protection assay were used to study MHC class II expression. Immunoblotting was done to study downstream signals of IFN gamma.

In a normal adaptive immune response, only around 0.0001% of T-cells are activated. In contrast, superantigen exposure can activate up to 30% of the T-cell pool, leading to severe pathologies following infection ( 6, 7 ). crystalline dry cleaners

"WebCytokines are a category of signaling molecules that mediate and regulate immunity, inflammation and hematopoiesis. Cytokines are produced throughout the body by cells of diverse embryological origin. Cytokine is a general name; other names are defined based on their presumed function, cell of secretion, or target of action. " - Cytokine induction human mhc class ii
