| Research Abstract |
The steroid receptor (SR) complex contains FKBP51 and FKBP52, which bind to tacrolimus (TAC) and cyclophilin 40, which in turn binds to cyclosporine (CYA); these influence the intranuclear mobility of steroid-SR complexes. Pharmacodynamic interactions are thought to exist between steroids and calcineurin inhibitors (CNIs) on the SR complex. We examined the effect of CNIs on steroid sensitivity. We examined the steroid sensitivity of mixed culture with both methylprednisolone (MPSL) and CNIs in 30 healthy subjects.and MPSL and cortisol sensitivity were examined before and after CNI administration in 23 renal transplant recipients.
Steroid sensitivity increased with both TAC and CYA. Furthermore, TAC had a greater effect on increasing sensitivity. Thus, concomitant administration of CNIs and steroid can increase steroid sensitivity. However, we could not have demonstrated the action mechanism, though we are resolving the action mechanism, using Jurkat cell knockdown FKBP51 with SiRNA
