#InflammasomePower! 💥New paper alert💥 How is NLPR3 primed & activated in chronic non-communicable inflammatory diseases? With @oceanedufies.bsky.social &co we show that chronic exposure to oxPAPC drives NRF2 activation that primes & activates NLRP3 sustaining #atherosclerosis in mice & humans! 👇👇👇
Chronic sensing of host-derived lipids is an all-in-one signal that primes and activates NLRP3.
Activation of the NLRP3 inflammasome leads to the production of bioactive interleukin (IL)-1β fostering atherosclerosis. The current dogma is that NLRP3 must be first primed by microbial stimuli, know...

#EpigeneticPower! 💥 #NewPaperAlert! We show @cp-immunity.bsky.social that endogenous oxidized lipids decide whether host survives or dies during #sepsis, #ARDS, or Staph infection! Ox lipids bind & inhibit #AKT, boosting inhibitory H3K27 methylation via EZH2 & blocking #IL10!
Epigenetic silencing of interleukin-10 by host-derived oxidized phospholipids supports a lethal inflammatory response to infections
