NLRP3-mediated glutaminolysis controls microglial phagocytosis to promote Alzheimerโ€™s disease progression How NLRP3 impacts Alzheimerโ€™s disease (AD) is unclear. McManus etย al. find that NLRP3 is located at mitochondria where it regulates microglial metabolism. Depletion or chronic pharmacological inhibiti...

I am thrilled to share our latest article that has been published in @cp-immunity.bsky.social. We describe a new role for NLRP3 outside of its #inflammasome complex, where it can regulate microglial #metabolism & key metabolites that affect the epigenetic landscape(1)

Microglia degrade Alzheimerโ€™s amyloid-beta deposits extracellularly via digestive exophagy Jacquet et al. shows that microglia use digestive exophagy to engage large Aฮฒ deposits that cannot be phagocytosed, forming acidic extracellular compartments on the aggregates into which lysosomal enzymes are exocytosed. The PI3K-AKT pathway modulates this process. Microglia also exocytose intralysosomal undigested fibrillar Aฮฒ toward extracellular aggregates, potentially contributing to plaque growth.
