Fat accretion in a subpopulation of hepatocytes as a strategy to protect the whole liver against oxidative stress and lipotoxicity.
Résumé
: Fatty liver can be induced by obesity, some drugs and alcohol intoxication. In this liver lesion, lipid accumulation can involve only some hepatocytes but the significance of this cell-to-cell heterogeneity is unknown. In a recent work, Dr Pol et al. propose that high-fat hepatocytes could protect the cell population against oxidative stress and lipotoxicity.
