In this study, HFHCCC diet was used to induce NASH liver fibrosis, with the stage of F1-2, and KCs cells were observed in the liver tissue of mice at 24 weeks The significant recruitment of neutrophils and the recruitment and release of pro-inflammatory cytokines, chemokines and colony-stimulating factors, but CD4+ T cells, CD8+ T and other adaptive immune-related cells and cytokines did not change significantly before and after the HFHCCC diet modeling, which is also basically consistent with the results of human research. The gene discussed is CD4; the disease is Hepatic fibrosis.
