Abstract Decrease in adult neurogenesis has been described to correlate with Alzheimer’s disease (AD) progression, and we have previously demonstrated a causal link between Amyloid-beta oligomers (AβOs) accumulation in adult neural stem cells (NSCs) and reduced SVZ neurogenesis in AD at pre-symptomatic stage. Here we investigated if AβOs targeting in the dentate gyrus of young AD mice can rescue adult hippocampal neurogenesis (AHN) and recover AD-related memory deficits. Using a disease modifying gene-therapy approach to neutralize intracellular natural-occurring AβOs in the hippocampal progenitors, we could rescue proliferation and differentiation deficits of AD-NSCs in vitro and AHN-related memory deficits in vivo. These data indicate neurogenesis as a model of AD deficits leaded by intracellular AβOs and provide AβOs gene-immunotargeting exploitable as an innovative therapeutic intervention to counteract disease onset and progression.
