Shirai et al. also suggested that the interactive effect between Ang II and LPS-TLR4 played a pivotal role in liver fibrosis development in nonalcoholic steatohepatitis, which may be through activation of myeloid differentiation factor 88 (MyD88), NF-κB and TGF-β expressions. The gene discussed is AGT; the disease is Hepatic fibrosis.
