Effector CAR T-Cells for Treatment of Alzheimer’s Disease

Tech ID: T-020995

Published Date: 5/14/2025

Value proposition: Using CAR T-cells to treat Alzheimer’s disease and other neurodegenerative diseases through Ab-specific activation.

Technology Description

While CD4+ (helper or effector) T-cells play complex roles in the pathophysiology of Alzheimer’s disease (AD), they are one of the main responding cell subpopulations to neurodegenerative conditions. Inspired by a strategy similar to chimeric antigen receptor (CAR)-based cancer treatments, researchers at Washington University in St. Louis have developed a prototype of CAR T-cells for the treatment of Alzheimer’s disease.

CAR receptors effectively respond in vivo and can recognize their peptides. Engineered CAR T-cells are highly specific to CD4 with minimal CD8 infiltration (bottom left). When injected into mice, in CAR-T cell treated groups (right side), Ab plaques are significantly reduced (bottom right, top) alongside a reduction in microgliosis (as measured by Iba1, bottom right, bottom).
