Abstract

Choi et al. show that chronic alcohol consumption induces CYP2E1-mediated reactive oxygen species (ROS) production by hepatocytes, which is compensated by GSH generation through xCT-mediated uptake of cystine. The parallel release of glutamate stimulates mGluR5 on hepatic stellate cells (HSCs) to produce 2-AG, which, in turn, activates CB₁R on neighboring hepatocytes to induce de novo lipogenesis.
