Dr Róisín McManus @roisinmcmanus.bsky.social · Feb 3

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)

NLRP3-mediated glutaminolysis controls microglial phagocytosis to promote Alzheimer’s disease progression

How NLRP3 impacts Alzheimer’s disease (AD) is unclear. McManus et al. find that NLRP3 is located at mitochondria where it regulates microglial metabolism. Depletion or chronic pharmacological inhibiti...

Five days of indulging in chocolate bars, crisps and other junk foods can lead to lingering changes in brain activity, a study shows1. The resulting brain patterns are similar to those seen in people who have obesity.
