Stage-specific roles of clonally expanded CD8+ T cells in regulating
amyloid pathology in Alzheimer’s disease models
"...Expanded TCR-expressing CD8+ T cells preferentially infiltrate the brain, exacerbating plaque deposition. Moreover, brain-infiltrating CD8+ T cells impair microglial transition into disease-associated states, suppressing amyloid clearance via CCL5-CCR5 signaling. Pharmacological blockade of CCL5 attenuates amyloid deposition, whereas CCL5 administration aggravates pathology. Notably, T cell depletion at later disease stages
exacerbates amyloid pathology, suggesting a temporal shift in their function"...
