Interferon gamma decreases hepatic stellate cell activation and extracellular matrix deposition in rat liver fibrosis
G S Baroni, L D'Ambrosio, P Curto, A Casini, R Mancini, A M Jezequel, A Benedetti – 1 May 1996 – Interferon gamma (IFN‐γ) inhibits in vitro the activation of hepatic stellate cells (HSC), the primary extracellular matrix‐producing cells in liver fibrosis. This study was undertaken to determine in vivo the effect of IFN‐γ in the rat model of liver fibrosis induced by dimethylnitrosamine (DMN), where HSC activation represents an early response to cell injury. Rats were killed after 1 or 3 weeks of treatment with DMN, IFN‐γ, DMN + IFN‐γ, or saline.
