Excited to share new work by Guli Agirman + co that identifies a direct mechanism linking gut microbial imidazole propionate to stress! 🧠🦠 Btw this image was made by Nano Banana Pro 🍌. First time I've gotten a model to accurately generate a science graphic 🤯 authors.elsevier.com/a/1mA5M6t8JE...

Happy to share this paper in final form rdcu.be/eH8tj, with more info on neuronal responses and potential mechanism of actions! The results suggest that there is neural interoception of microbial metabolic state 🧠🦠 We hope they can inspire more work in this area!

5/5 Awardee @chuchuzhang.bsky.social explores how different body states (eg, pregnancy) may change what neurons sense & how they respond. Her work may lead to new ways to address nausea associated w/ pregnancy🤰 & chemo.

It was an honor to highlight this fantastic work by Cheng and Venkatesh et al of the Gordon lab. Many thanks to them, and to Francis Chandra for doing all the heavy lifting on this Spotlight! @cp-cellchembiol.bsky.social
Great highlight by Chandra and @pipethero.bsky.social on recently published work by my colleague @flash-point.bsky.social (from his postdoc work) on endocannabanoids produced by specific members of the gut microbiota that likely impact host satiety/appetite. @isbscience.org

Delighted to share work by Kristie Yu, Celine Son, & co showing that selective fructan metabolism by the gut microbiome can contribute to host associative learning of dietary preference, even when it comes to choosing between diets with the same perceptual salience (and macronutrient composition!)
