Cancer Signals Could Help the Brain Fight Alzheimer's, Mouse Study Finds

TL;DR
A mouse study shows tumors releasing cystatin-C into the bloodstream can cross the blood-brain barrier, bind amyloid-beta, and activate microglia via Trem2 to clear plaques, sometimes improving memory in Alzheimer’s-like mice. While intriguing, these results are in animals and it's unknown whether humans would experience a similar protective effect; researchers are exploring therapies that mimic this mechanism without cancer.
