STINGing the brain: S-nitrosylation drives neuroinflammation in Alzheimer's disease.

Abstract

Neuroinflammation is a major secondary driver of Alzheimer's disease (AD). In this issue of Cell Chemical Biology, Carnevale et al.1 demonstrate that S-nitrosylation of the cyclic GMP-AMP synthase (cGAS) stimulator of interferon genes (STING) pathway sustains pathological neuroinflammation in AD, identifying a promising therapeutic target for this devastating disease.
