Brain resilience switch: CgA protein shields against Alzheimer's symptoms in mice

UCSD researchers identify chromogranin A (CgA) as a key driver linking amyloid-beta/tau pathology to cognitive decline: mice lacking CgA still develop Alzheimer’s brain changes but remain cognitively sharp, revealing innate resilience mechanisms and a potential preventive target, though human confirmation and safety considerations are needed, and some authors have industry ties.

Stress protein linked to resilience against Alzheimer's decline, study finds

Researchers report a 40-gene pattern that distinguishes normal aging, symptomatic Alzheimer's, and a resilient state, and identify Chromogranin A (CgA) as a stress-related protein that links cellular stress to Tau tangles. In mice, removing CgA reduced Tau buildup and preserved memory, especially in females, suggesting resilience pathways can sustain cognition despite brain damage. While promising, these findings are in animals and must be validated in humans, with resilience markers potentially guiding early prevention.
