Mitochondrial stress in human microglia rewires metabolism, disrupts neuronal communication, and promotes senescence.
Three things to remember
- Mitochondrial proteotoxic stress depletes S-adenosylmethionine and remodels lipids in microglia.
- UPRmt activation triggers inflammatory signaling and impairs proteostasis in human brain models.
- Disrupted microglial communication accelerates senescence and neurodegeneration in organoids.
