Treg-microglia crosstalk in Alzheimer's disease: stage-dependent dynamics, molecular mechanisms, and translational challenge

3 weeks 1 day ago
Alzheimer's disease (AD) is characterized by amyloid-beta (Aβ) deposition, tau hyperphosphorylation, and chronic neuroinflammation. Emerging evidence from preclinical models suggests that aberrant immune crosstalk between regulatory T cells (Tregs) and microglia may contribute to disease progression, though its precise role in human AD remains to be fully elucidated. In rodent models, Tregs have been shown to cross the blood-brain barrier and, through cell-contact-dependent mechanisms and...
