The study shows that liver X receptors, which are regulators of cholesterol, fat and inflammatory gene expression, also control the fibrosis-making cells of the liver, known as hepatic stellate cells. In chronic liver injury (due to excess fat, for example), stellate cells become activated and launch an inflammatory and fibrotic cascade that can eventually result in liver fibrosis. Liver X receptors, when stimulated, “turn on” several hundred genes that have been shown to suppress these inflammatory processes.
The researchers noted in an experiment involving mice that after replicating chronic liver injury, mice without liver X receptors had dramatically more liver fibrosis than normal mice.
