Restoring microglial and astroglial homeostasis using DNA immunization in a Down Syndrome mouse model
Using DNA Immunization to Restore Support Cell Balance in a Down Syndrome Mouse Model

Abstract
Vaccination against the Aβ fragment improved cognitive and behavioral abilities in Ts65Dn mice, a model for Down Syndrome.
- Anti-Aβ vaccination led to the production of antibodies and facilitated the removal of Aβ from brain regions.
- Reduced neurodegeneration was observed in vaccinated mice, alongside restoration of healthy microglial and astroglial cell functions.
- Vaccinated Ts65Dn mice showed enhanced performance in spatial-learning tasks and reduced typical motor hyperactivity.
- Short-term memory abilities were restored in vaccinated mice, suggesting potential cognitive benefits.
- The findings may indicate that individuals with Down Syndrome could benefit from early immunotherapy targeting Aβ.
