By equipping these cells with a chimeric antigen receptor (CAR), scientists enabled them to specifically target and clear beta-amyloid plaques, the toxic protein deposits that accumulate in brain tissue and drive neurodegeneration. In mouse trials, a single injection prevented plaque formation in young healthy rodents and reduced existing plaque levels by half in older mice. While the approach is still being refined to minimize side effects and must be evaluated for human safety, it holds promise both as a preventive measure and as a treatment at various stages of Alzheimer\u2019s. The same technology may eventually be adapted for cancer therapy by reprogramming the cells to target tumor markers.<\/p>\n<hr>\n<p>Alzheimer\u2019s disease (AD) is the leading cause of dementia and is characterized by progressive amyloid accumulation followed by tau-mediated neurodegeneration. Despite advances in anti-amyloid immunotherapies, important limitations remain, highlighting the need for new therapeutic strategies. Here, we introduce anti-amyloid chimeric antigen receptors expressed in astrocytes (CAR-A) and validate their function <i>in vitro<\/i>. We show that two CAR-A designs reduce amyloid and associated pathology after plaque formation and prevent early plaque deposition <i>in vivo<\/i>. Single-nucleus RNA sequencing shows that CAR-A treatment induces a distinct glial response to amyloid pathology involving coordinated activity of astrocytes and microglia. Each construct additionally elicits distinctive, receptor-specific effects in astrocytes or microglia.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at Washington University in St. Louis have developed a novel cell therapy for Alzheimer\u2019s disease using genetically modified astrocytes \u2014 the brain\u2019s most abundant cells.
