#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.

Many thanks to you and your team @sunnyshinlab.bsky.social for your contribution. It was a pleasure working with you!

Many thanks for your insightful chapter Mikel!

We hope you find our new book informative and inspiring for your #immunometabolism studies!

In this new book, we and leaders in the field summarize the recent history of the ever-growing field of immunometabolism, the current state of the field, and future directions including the generation of new therapies harnessing and targeting immunometabolism.

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!

Pleased to share our latest paper in Science Advances on myeloid cell ‘trained hypercoagulability’! 🚀 Project led by @aislingrehill.bsky.social - huge thanks to our collaborators & funders @tcddublin.bsky.social @researchireland.bsky.social CHI and HRB Ireland tinyurl.com/df4fsrrx

Macrophages recycle phagocytosed bacteria to fuel immunometabolic responses - Nature Phagocytosed bacteria can serve as an alternative nutrient source for macrophages, influencing their metabolic and immune responses through the recycling of microbial components, with the process regu...

#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! 🤩
