The Sigma-1 Receptor at the Crossroad of Proteostasis, Neurodegeneration, and Autophagy

Trends Neurosci. 2020 Feb;43(2):79-81. doi: 10.1016/j.tins.2019.12.002. Epub 2020 Jan 6.

Abstract

Neurodegenerative diseases are linked to dysfunctional proteostasis and disturbed autophagy. Here, we discuss how the sigma-1 receptor (Sig-1R) may act at the intersection of this interaction, as loss-of-function mutations of this unique chaperone are associated with defective autophagy and its pharmacological activation induces autophagic activity.

Keywords: ALS; ER; autophagy; neurodegeneration; sigma-1 receptor.
