M2 Kupffer cells promote M1 Kupffer cell apoptosis: A protective mechanism against alcoholic and nonalcoholic fatty liver disease

These data uncover a novel mechanism regulating the M1/M2 balance that relies on apoptotic effects of M2 KCs towards their M1 counterparts. They suggest that promoting M2-induced M1 KC apoptosis might prove a relevant strategy to limit alcohol- and high fat-induced inflammation and hepatocyte injury.
