چکیده
|
Mesangial cells are the main source of renal interstitial fibrosis in diabetic nephropathy (dn). interferon-γ (ifn-γ) is a key cytokine that may play a potential therapeutic role in reducing fibrosis. here,we focus on the effects of ifn-γ on human mesangial cells (hmcs) treated with high glucose. this study shows that ifn-γ phosphorylates stat1,suppresses hmc proliferation,and downregulates mrna and protein levels of transforming growth factor-β1 (tgf-β1) and connective tissue growth factor (ctgf) in hmcs treated with high glucose. the regulation of p-stat1 could change hmc proliferation and the expression of fibrotic cytokines tgf-β1 and ctgf in hmcs. these data indicate that ifn-γ could activate stat1 to suppress the increase in tgf-β1 and ctgf synthesis in hmcs induced by high glucose. this paper may lead to new therapeutic treatments of dn. copyright © 2011 by institute of pharmacology polish academy of sciences.
