Alternative model for Alzheimer’s neurodegeneration

GluN3A knockout mouse: Alternative model for Alzheimer's neurodegeneration
GluN3A (in the diagram, NR3) is an inhibitory subunit within NMDA receptor assemblies, which function as glutamate-gated cation channels. GluN3A is a key regulator of neuronal activity and calcium homeostasis in both early and late life. Credit: Emory University

In recent debate over the FDA’s approval of the Alzheimer’s drug aducanumab, we’ve heard a lot about the “amyloid hypothesis.” In that context, it’s refreshing to learn about a model of Alzheimer’s neurodegeneration that doesn’t start with the pathogenic proteins amyloid or Tau.

Instead, a new paper in Alzheimer’s & Dementia from Emory neuroscientist Shan Ping Yu and colleagues focuses on an unusual…
