Endoplasmic reticulum stress, PrP trafficking, and neurodegeneration.

摘要

In this issue of Developmental Cell, Rane et al. report a cellular pathway to link PrP(Sc), via ER stress and the activation of a preemptive quality control process, to neurodegeneration in a PrP-dependent manner. This pathway puts together several pieces in the puzzle of the relationship between PrP(Sc) and brain damage and may in part explain the mechanism of prion neurodegeneration.
