Interleukin (IL)-10 is an anti-inflammatory factor that suppresses renal fibrosis and improves renal function in CKD rats. IL-20 belongs to the IL-10 family; therefore, we sought to determine whether IL-20 is involved in CKD. CKD patients at stage five expressed significantly higher IL-20 in serum than controls. Immunohistochemical staining demonstrated that more IL-20 protein was expressed in the kidney tubular-epithelial cells, mesangial cells, and immune cells of CKD rats with a 5/6 nephrectomy. The lung, liver, and heart tissue of CKD rats also overexpressed IL-20. Thus, we treated two tubular epithelial cells, TKPTS and M-1 cells, with IL-20 to study its effects on CKD. IL-20 treatment induced apoptosis in these cells via caspase-3 activation. Incubating IL-20 with rat interstitial fibroblasts, NRK-49F cells, upregulated TGF-beta1 production, one key inducer for renal fibrogenesis. Therefore, IL-20 injured renal epithelial cells and induced fibroblasts to produce TGF-beta1 that hastened the progression of CKD.
