My (little) take on how metabolism regulates neutrophil development and functions and why it should be studied more. Happy if it is helpful to anyone interested!

I’m happy to share our latest work on tumour necrosis! During my time in the @megeblad.bsky.social lab, we found that tumour necrosis is not a passive phenomenon secondary to tumour growth, but an active phenomenon driven by neutrophils and NETs! Thread below: (1/13)

Neutrophils actively induce tumour necrosis, driving vascular occlusion, pleomorphic necrosis and metastasis.

#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...

Amitava Sinha via the @preprintclub.bsky.social‬ wrote a nice Journal Club article on a preprint by from the Angelo lab @stanfordmedicine.bsky.social that describes spatial immunometabolic zonation in tuberculosis granulomas: www.nature.com/articles/s41...
Spatial immunometabolic zonation in tuberculosis granulomas - Nature Reviews Immunology
A preprint by McCaffrey and Delmastro et al. delineates distinct immunometabolic zones of tuberculosis granulomas and reports that hypoxia is a key driver of immune subversion.
