Suppression of Allograft Fibrosis by Regulation of Mammalian Target of Rapamycin-Related Protein Expression in Kidney-Transplanted Recipients Treated with Everolimus and Reduced Tacrolimus
BACKGROUND Although renoprotective effects of everolimus (EVR) in kidney transplantation (KTx) have been widely reported, its pathophysiological mechanism remains unclear. MATERIAL AND METHODS We compared changes in eGFR (ΔGFR, ml/min/1.73 m²) and the ratio of the fibrotic area in biopsy specimens (ΔFI,%) from 3 months to 3 years after KTx between the EVR+ group (EVR addition and Tac reduction early after KTx, n=32), and the EVR- group (normal Tac without EVR, n=28). We also immunohistochemically evaluated mTOR-related protein expression. RESULTS ΔGFR and ΔFI in the EVR+ vs. EVR- groups were -0.27±6.8 vs. -9.8±12.8 (p
