#ImmunometabolismPower! Excited to share our review @cp-cellchembiol.bsky.social with super-talented @tristramryan.bsky.social about the activity of immunometabolites of the #TCA #Krebs cycle working as metabolic damage-associated molecular patterns #metaDAMPs in health & disease!

I'm so delighted to share that I have been awarded a K99/R00 from NIH/NIAID to study the priming and activation mechanisms of NLRP3 against inflammatory diseases 🥳 !! This would never have been possible without the amazing mentoring and support from Ivan @lozanzi.bsky.social !!

#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 oxidi...

Online now: Epigenetic silencing of interleukin-10 by host-derived oxidized phospholipids supports a lethal inflammatory response to infections
dlvr.it
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.

#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!

#WeekendRead! #WeAreWhatWeEat! Lesbats, Garaude &co show @nature.com that macrophages recycle phagocytosed bacteria to fuel their metabolism but that dead, compared to live, bacteria still feed macrophages but reduce the induction of ROS & the secretion of IL1b! www.nature.com/articles/s41...

Leaving Boston in a few days after a productive time in the Zanoni Lab at @bostonchildrens.bsky.social and Harvard Medical School. Huge thanks to Ivan @lozanzi.bsky.social and the whole lab for their support and inspiration. I will miss you all! Excited to keep working together on cool science! 🤩
