Lipid-induced granules in hepatocytes alleviate liver fibrosis

C)-modified mRNA of pro-fibrotic hepatokine tissue inhibitor of metalloproteinase 2 (Timp2) and its reader Y-box binding protein 1 (YBX1) were recruited into LIGs, thereby inhibiting Timp2 mRNA translation and consequently feedback suppressing liver fibrosis. Moreover, LIGs were identified in human MASLD livers and exhibited reverse correlation with fibrosis progression. Therefore, we identified a new granule in steatotic hepatocytes and elucidated its role in restraining liver fibrosis.
