Summary
The discovery of cyclosporine (CsA) enabled critical advances in transplantation, providing unique insight into the molecular mechanisms of cell signaling and immunological activation, introducing pharmacological monitoring and concentration-controlled therapy, and dramatically improving the safety and success of clinical transplantation. Inhibition of molecular events downstream of the trimolecular complex comprising cyclophilin, calcineurin A, and calcineurin B selectively inhibits T cell activation through dephosphorylation of the NFAT (nuclear factor of activated T cells). Related actions of CsA are now recognized in the replication of HIV and other viral diseases, providing novel insights to antiviral therapy. CsA has a narrow therapeutic index and complex metabolism, governed by genes encoding cytochrome P450 pathways and the ATP-binding cassette transporter P-glycoprotein, which determine absorption, distribution, metabolism, and excretion of CsA. Therapeutic monitoring and sparse-sample prediction are widely employed to optimize clinical utilization and mitigate its numerous drug–drug interactions. CsA has revolutionized clinical transplantation and forever changed outcomes and expectations in this field.
