We’re excited to report work led by postdoc Jennifer Porat in the lab, finding that DNA accumulates on the surface of living cells and that the secreted extracellular protein DNASE1L3 can modulate its levels on B and T cells. With a new twist for ATAC-seq as well www.biorxiv.org/content/10.1...

DNASE1L3 surveils mitochondrial DNA on the surface of distinct mammalian cells

The extracellular space is a critical environment for discriminating self versus non-self nucleic acids and initiating the appropriate immune responses through signaling cascades to relay information ...

#WeekendRead! #ImmunometabolismPower! Formiga, Sokol &co show @cp-cellhostmicrobe.bsky.social that #microbiota derived cadaverine 🧟‍♂️ controls macrophage metabolism & gut inflammation. Low 🧟‍♂️ activates NRF2 promoting OXPHOS & homeostasis, while high 🧟‍♂️ drives glycolysis & intestinal inflammation 🔥 !!

Immunometabolic reprogramming of macrophages by gut microbiota-derived cadaverine controls colon inflammation

#Microbiota #FriendOrFoe? Our own @bostonchildrens.bsky.social Chatila, Benamar &co show @cp-immunity.bsky.social that #gut microbiota drives Notch3+ Tregs which migrate to brain & interacts with microglia becoming Th17 cells, subvert CNS resident neuropetide-responsive Tregs, supporting MS/EAE!

Notch3 destabilizes regulatory T cells to drive autoimmune neuroinflammation in multiple sclerosis

Benamar et al. demonstrate that Notch3+ Treg cells are increased in multiple sclerosis and in EAE. They are induced in the gut by microbiota and translocate to the CNS to degenerate into pathogenic Th...

What a fantastic day to start the Immunobiology of #PRRs Symposium in beautiful Lausanne! Much looking forward to being part of an amazing line up of speakers, & to presenting a brand new story on a 100-year old protein whose function remains poorly understood! 😉

#WeekendRead! #MicrobiotaPower! Jang, Jung &co show @natmetabolism.nature.com that dietary fibre protects against dietary fructose-driven insulin resistance & liver steatosis via promoting fructose utilization by small intestine microbiota & favoring anti-oxidant responses in the liver!

Dietary fibre-adapted gut microbiome clears dietary fructose and reverses hepatic steatosis - Nature Metabolism

The dietary fibre inulin is shown to promote fructose catabolism by the small intestinal microbiome, thereby mitigating fructose-induced hepatic lipogenesis and steatosis.

#InterferonPower! Li, Park &co show @cp-immunity.bsky.social that IL-15 negatively regulates CD103 expression on CD8 T cells allowing formation of effector T cells & that engagement of CD103 on CD8 T cells by E-cadherin+ dendritic cells is necessary to drive memory formation via type I IFNs & IL-12

Integrin CD103 expression in naive CD8+ T cells promotes cytokine-driven acquisition of memory phenotype and effector function

Integrin CD103 mediates memory T cell tissue residency by binding E-cadherin-expressing epithelial cells, but why CD103 is also expressed on circulating naive CD8+ T cells has been unclear. Li et al. ...
