ER strikes again: Proteostasis Dysfunction In ALS

EMBO J. 2016 Apr 15;35(8):798-800. doi: 10.15252/embj.201694117. Epub 2016 Mar 11.

Abstract

The precise contribution of endoplasmic reticulum (ER) chaperone protein disulfide isomerase (PDI) variants in human amyotrophic lateral sclerosis (ALS) patients to the pathogenesis of ALS remained unclear. In the present study, Woehlbier et al (2016) demonstrated that these PDI variants are capable of altering motor neuron morphology, impairing the expression of synaptic proteins, and compromising neuromuscular junction (NMJ) integrity.
