Mechanism of action

Cyclosporine binds to cyclophilin and the resulting complex inhibits calcineurin, a serine/threonine phosphatase essential for dephosphorylating NFAT (nuclear factor of activated T cells). This prevents NFAT translocation to the nucleus and subsequent IL-2 and other cytokine gene expression, thereby suppressing T-cell mediated immune responses. It is a non-selective immunosuppressant used primarily in transplantation and autoimmune conditions.
