| Biochem/physiol Actions: | A fungal metabolite possessing potent immunosuppressive properties. It inhibits the T-cell receptor signal transduction pathway via the formation of cyclosporin A−cyclophilin complex that inhibits calcineurin (protein phosphatase 2B). Inhibits nitric oxide synthesis induced by interleukin 1α, lipopolysaccharides and TNFα. Can block cytochrome c release from mitochondria. |
| Biochem/physiol Actions: | Cyclosporin A has been shown to inhibit the functioning of several nuclear proteins involved in T-cell activation at the level of mRNA transcription. It forms a complex with its intracellular receptor cyclophilin, which can then bind to calcineurin, a Ca2+ - and calmodulin-dependent protein phosphatase, inhibiting its enzymatic activity. It was found to suppress the replication of hepatitis C virus genome in cultured hepatocytes. |
| Biochem/physiol Actions: | Potent immunosuppressant; inhibits nitric oxide synthesis induced by interleukin 1α, lipopolysaccharides and TNFα; blocks cytochrome c release from mitochondria. |
| General description: | Chemical structure: peptide |
| General description: | Cyclosporin A is a fungal metabolite with immunosuppressive properties. Cyclosporin A is a non-polar cyclic oligopeptide produced by the fungus Tolypocladium inflatum. It is a potent immunosuppressive agent, affecting primarily T-lymphocytes. |
