Toll-like receptor activation suppresses ER stress factor CHOP and translation inhibition through activation of eIF2B
2012
Endoplasmic reticulum (ER) stress and activation of the unfolded protein response inhibits de novo protein translation and activates CHOP. However, the long-term induction of these pathways in response to prolonged ER stress would be detrimental. Tabas and colleagues now reveal a mechanism through which Toll-like receptor signalling suppresses CHOP activation and promotes protein translation, thus allowing cells to adapt to persistent ER stress.
