In some studies, TLR2 knockout enhances NASH in murine NASH models induced by methionine–choline‐deficient diet, accompanied by elevated expression of inflammatory and fibrosis markers, suggesting a protective role of TLR2‐mediated signals (Szabo et al, 2006; Rivera et al, 2010). The gene discussed is TLR2; the disease is metabolic dysfunction-associated steatohepatitis.
