The interaction between immune cells and hepatic stellate cells (HSCs) can modulate the development of hepatic fibrosis. It can also regulate hepatic fibrosis and liver cirrhosis caused by excessive deposition of extracellular matrix (ECM). This article reviews the action mechanism of immune cells on liver fibrosis and the effect of

Astragalus membranaeus

and its active components on immune cells. In-depth study of interaction between immune cells and HSCs on the pathogenesis of liver fibrosis

and the regulatory effect of

Astragalus membranaeus

and its active components on immune mechanism will provide new insights in the treatment of liver fibrosis.
