WebFeb 15, 2005 · The use of FasL as an immunomodulatory agent to induce peripheral tolerance invokes several considerations. The level of expression of FasL appears to be important to its therapeutic potential, 56 and as such needs to be fine-tuned depending on the model system used and the tissue targeted for expression. WebTolerance is defined as the lack of specific immune response to antigen. There is a central and peripheral tolerance of B or T cells. Central tolerance of T cells, which makes the repertoire of T cells in the periphery non-responsive to self-antigens, is clonal deletion in the thymus (or negative selection). bisphosphatase deficiency treatmentWebFortunately, additional tolerance mechanisms exist that restrain the numbers and or function of T cells that are reactive to developmental or food antigens, which are not … bisphosphate definition

"WebPeripheral tolerance to allergens involves many suppressive factors, such as IL-10, TGF-β, CTLA4, and PDCD1. 78 Normal, healthy immune responses to mucosal antigens are generated by allergen-specific peripheral T cell suppression mediated by IL-10, TGF-β, and other suppressive factors and by deviation toward a Treg cell response.
