Web22 aug. 2003 · Hepatology 2002 TLDR Results indicate that leptin is profibrogenic in activated HSCs and can signal via the Jak‐Stat pathway, and up‐regulation of leptin signaling in liver injury could contribute to enhanced fibrogenesis, particularly in states in which leptin levels are high. 381 PDF WebInhibition of Arg1 in activated HSCs efficiently inhibited collagen production but not cell proliferation. HSC activation is accompanied by a switch of arginine catabolism from iNOS to Arg1. Inhibition of Arg1 decreases collagen synthesis. Therefore, we conclude that Arg1 can be a therapeutic target for the inhibition of liver fibrogenesis.
