#ThatIsTheQuestion Post-translational modifications of NLRP3: to prime or not to prime? Thrilled to have had the opportunity to write this review with @lozanzi.bsky.social 🤩! We discuss how PTMs coordinate during priming to control NLRP3 stability, location & partners. tinyurl.com/35dy5rcc

#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 Upon pathogen detection, phagocytes trigger immunity. This process induces tissue stress and the formation of host-derived molecules that further tune immune responses. We show that host-derived oxidized phospholipids accumulate upon microbial encounter, epigenetically suppress IL-10, and exacerbate harmful inflammation. Thus, targeting oxPLs represents a therapeutic strategy to treat deranged inflammation after infection.

Epidermal ZBP1 stabilizes mitochondrial Z-DNA to drive UV-induced IFN signaling in autoimmune photosensitivity ZBP1 and mitochondrial Z-DNA drive autoimmune photosensitivity via cGAS-STING activation.

#InterferonFriendOrFoe?! Klein @kahlenberglab.bsky.social &co show Science Immunology that UV drives mitochondrial Z-DNA to induce type I & III IFNs in keratinocytes. IFN-I upregulates ZBP1 that binds Z-DNA activating cGAS-STING to boost IFNs, photosensitivity & inflammation in #Lupus skin!
