Raes Lab

Last Friday, we had the pleasure of attending the very first Belgian Microbiome Network Symposium in Antwerp!

Huge shoutout to @ruvaur.bsky.social, Sarah Ahannach and Ludovica Marinelli for organizing this great new initiative and bringing the community together!✨

Host factors dictate gut microbiome alterations in chronic kidney disease more strongly than kidney function - Nature Microbiology A covariate-aware analysis reveals that microbiome changes in the gut of patients with chronic kidney disease are better explained by intestinal transit time than by kidney function.

Big congrats to our colleague @krukowskihubert.bsky.social
on the Nature Microbiology paper linking gut transit time and diet to CKD microbiome changes. Another step in microbiome research!🧫

Probiotic-mediated modulation of gut microbiome in students exposed to academic stress: a randomized controlled trial - npj Biofilms and Microbiomes npj Biofilms and Microbiomes - Probiotic-mediated modulation of gut microbiome in students exposed to academic stress: a randomized controlled trial

Exams = stress. 📚 Our new study shows that a probiotic strain (L. rhamnosus CNCM I-3690) modulated the gut microbiome during academic stress, with ties to lower anxiety.
