Dataset Summary
TitleBeneficial effect of ACI-24 vaccination on microglial phenotypes in an amyloidosis mouse model
DescriptionAmyloid-beta (Aβ) deposition is an initiating factor in Alzheimer´s disease (AD). Microglia are the brain immune cells that surround and phagocytose Aβ, but their phagocytic capacity declines in AD. This is in agreement with studies that associate AD risk loci with genes regulating phagocytic function. Immunotherapies are currently pursued as therapeutic strategies against AD and there are increased efforts to understand the role of the immune system in ameliorating AD pathology. Here, we evaluated the effect of the Aβ targeting ACI-24 vaccine in preventing the AD pathology in an amyloidosis mouse model. ACI-24 vaccination elicited a robust and sustained antibody response in APPPS1 mice with an accompanying reduction of Aβ plaque load, amyloid plaque-associated ApoE and dystrophic neurites as compared to non-vaccinated controls. Furthermore, plaque-associated microglia had the tendency to be more activated post vaccination. The lower Aβ plaque load triggered by vaccination with ACI-24 was in concordance with the bulk transcriptomic analysis that revealed a reduction in the expression of several disease-associated microglial signatures. Accordingly, plaque-distant microglia displayed a more ramified morphology, supporting beneficial effects of the vaccination on bulk microglial phenotypes. Our study demonstrates that administration of the Aβ targeting vaccine, ACI-24, triggers protective microglial responses that translate into a reduction of AD pathology suggesting its use as a safe and cost effective AD therapeutic intervention.
