health π§ New brain research targets Alzheimer's with immune protein mod
A research team discovered that modulating the immune protein PD-L1 can restore brain immune balance in Alzheimer's disease. This work was done by Taeyoung Park et al at Sungkyunkwan University and Yonsei University College of Medicine. The study, published on September 21, 2026, used Alzheimerβs disease mouse models. Blocking PD-L1 restored impaired microglial function and reduced abnormal neuronal hyperactivity. This suggests brain immune modulation could be a new therapeutic route for the disorder. π§
