In this issue of Nature Metabolism, Wang et al. identified a non-apoptotic caspase-8 function in metabolic dysfunction-associated steatohepatitis (MASH), in which hepatocyte-derived caspase-8 induces meteorin, which in turn activates hepatic stellate cells (HSCs) to drive fibrosis. This function reveals a potential therapeutic target to directly address fibrosis and reduce the progression of metabolic dysfunction-associated steatotic liver disease (MASLD).
