摘要

Kidney transplantation is the preferred therapy for kidney failure. The leading cause of graft loss is chronic allograftnephropathy (CAN). We hypothesize that Interleukin-13 (IL-13), protective against acute kidney graft rejection, isinvolved in CAN. In mouse kidney allografts, we observe after 2 weeks signs of interstitial inflammation progressing tovasculitis. By 6 weeks, CAN is manifest. IL-13 is overexpressed in allografts versus isografts (p<0.01) throughout thepost-transplant course. Concomitantly, we detect markers of fibrogenesis and epithelial-mesenchymal transition. To explorethis phenomenon, kidney proximal tubular epithelial cells were cultured with IL-13. Within 6 hours, we show increasedproliferation compared to untreated cells (p<0.01), occurring through activation of IL4Rα/JAK3 and Stat6 andblocked by anti-IL-13 monoclonal antibody. This is the first report of IL-13 inducing a specific biological activity in kidneyepithelial cells with a possible role in the damage control machinery, indicating its potential as a biomarker and therapeutictarget.
