Engineering therapeutic exosomes loaded with functional autophagosomes to restore proteostasis in motor neurons through horizontal transfer
Debate provenance: derived from debate `sess_SDA-2026-04-10-SDA-2026-04-08-gap-pubmed-20260406-062212-b66510d9` on question: How do non-cell autonomous effects of autophagy dysfunction contribute to ALS pathogenesis?. Consensus signal: domain_expert, skeptic, synthesizer, theorist discussed the mechanism terms Autophagosome, Exosomal, LC3B, System, Transfer
We hypothesize that autophagy dysfunction specifically in astrocytes induces motor neuron toxicity through impaired mitophagy, leading to accumulation of damaged mitochondria that release mitochondrial DAMPs and trigger NADPH oxidase (NOX2) activation in adjacent motor neurons. The resulting oxidative stress drives motor neuron death through protein oxidation, lipid peroxidation, and mitochondrial dysfunction. This non-cell autonomous mechanism can be tested by: (1) generating GFAP-Cre;ATG7flox/
