Rapamycin increases Alzheimer’s-associated plaques in mice, study finds

Researchers at UT Health San Antonio found that rapamycin causes an increase in beta-amyloid protein plaques in mouse models, contradicting its potential benefits. However, a novel method to decrease plaques was discovered by deleting the Tsc1 gene from microglia, leading to increased Trem2 levels and decreased plaques.
