However, iNKT cell‐produced IL‐4 could induce HSCs membrane protein GARP expression to promote liver fibrosis through TGFβ activation.[182] These findings suggest a shift in the pro‐fibrotic and anti‐fibrotic roles of iNKT cells across distinct stages of liver fibrosis, which may account for their cellular heterogeneity. The gene discussed is TGFB1; the disease is Hepatic fibrosis.
