WebThe CD40LG gene provides instructions for making a protein called CD40 ligand, which is found on the surface of immune system cells known as T cells. CD40 ligand attaches like a key in a lock to its receptor protein, CD40, which is located on the surface of immune system cells known as B cells. WebCD40 binds its ligand CD40L, which is transiently expressed on T cells and other non-immune cells under inflammatory conditions. A wide spectrum of molecular and cellular processes is regulated by CD40 engagement including the initiation and progression of cellular and humoral adaptive immunity.

WebIgE synthesis by B cells requires two signals. The first signal is delivered by the cytokines IL-4 or IL-13, which target the Cϵ gene for switch recombination. The second signal is delivered by interaction of the B cell surface antigen CD40 with its ligand (CD40L) expressed on activated T cells. This activates deletional switch recombination. WebMay 1, 1996 · The role of CD40–CD40L in regulating the APC capacity of B cells has recently been documented by showing that the combined administration of anti-CD40L and allogeneic B cells can diminish allospecific cytotoxic T lymphocyte and mixed lymphocyte responses ( 3 ).

WebHowever, as the tissue distribution widens for those cells that express CD40 and gp39, we can now show that this ligand-receptor pair also plays an important role in the selection of self-reactive T cells in the thymus (central tolerance) and the regulation of tolerance in mature T cells (peripheral tolerance). WebHowever, the CD40− CD40L pathway also plays a key part in T-cell effector function. Because of its many roles in adaptive immunity, the CD40–CD40L pathway is of great interest as a target for therapy in autoimmune inflammatory diseases.
