Studies also have shown that type 2 immune response can promote the development and progression of liver fibrosis, thereby promoting the activation of HSCs by producing IL-10, Arg-1, Ym1, and Fizz1 (Liu et al., 2004) whereas pro-inflammatory mediators such as iNOS could inhibit the activation or induce the apoptosis of HSCs (Allen and Sutherland, 2014; Pine et al., 2018). The gene discussed is IL10; the disease is Hepatic fibrosis.
