Glucose hypometabolism gates tau-dependent necroptosis.

Abstract

Tau pathology closely tracks neuronal loss in Alzheimer's disease, but how phosphorylated tau becomes lethal has remained unclear. Chen et al. identify a dual-hit mechanism: glucose hypometabolism removes a protective A20-mediated brake on necroptosis while phosphorylated tau scaffolds RIPK1 activation, driving tau-associated neuronal death.1.
