Hippocampal neural stem cell exosomes promote brain resilience against the impact of tau oligomers

1 year ago
A promising therapeutic intervention for preventing the onset and progression of Alzheimer's Disease (AD) is to protect and improve synaptic resilience, a well-established early vulnerability associated with the toxic effects of oligomers of Aβ (AβO) and Tau (TauO). We have previously reported that exosomes from hippocampal neural stem cells (NSCs) protect synapses against AβO. Here, we demonstrate how exosomes can also shield against TauO toxicity in adult mice synapses, potentially benefiting...

Microglial mechanisms drive amyloid-beta clearance in immunized patients with Alzheimer's disease

1 year ago
Alzheimer's disease (AD) therapies utilizing amyloid-β (Aβ) immunization have shown potential in clinical trials. Yet, the mechanisms driving Aβ clearance in the immunized AD brain remain unclear. Here, we use spatial transcriptomics to explore the effects of both active and passive Aβ immunization in the AD brain. We compare actively immunized patients with AD with nonimmunized patients with AD and neurologically healthy controls, identifying distinct microglial states associated with Aβ...
