Abstract

Toxic bile acids facilitate Fas and tumor necrosis factor-associated apoptosis-inducing ligand (TRAIL) death-receptor oligomerization and activation. Bile acid modulation of death-receptor signaling is multifactorial and includes trafficking of Fas to the cell surface, enhancing TRAIL-R2/DR5 expression, and suppression of function of cFLIP, an antiapoptotic protein modulating death-receptor function. Because bile acid-associated death receptor-mediated apoptosis is a common mechanism for cholestatic hepatocyte injury, inhibition of death receptors and their cascades may prove useful in attenuating liver injury during cholestasis.
