Product Description
Antibiotic. Potent immunosuppressor. Widely used after organ transplantation. Binds to cytosolic proteins of the cyclophilin family. Cyclosporin A-cyclophilin complexes block protein phosphatase 2B (PP2B; calcineurin), a key enzyme in T cell activation. As a result of the calcineurin inhibition, cyclosporine A blocks various cellular processes such as activation of T cells and expression of several lymphokines (especially IL-2). Inhibits cytochrome c release from mitochondria. Inhibits nitric oxide (NO) synthesis.
