What if microbiota-derived choline mediators trigger visceral hypersensitivity in IBS?
@JulienPujo @Bercik_Collins investigated mechanisms involved in mice on a phosphatidilcholine-enriched diet

This week, the Implementation Committee and CAG National Office staff met to formally kick off planning for the 2026 CDDW-CLM Conference! @Hookeyl @Bercik_Collins @StuartJ_
Timely discussions — especially as we mark World #DigestiveHealth Day 2025! #WDHD2025 #NourishToFlourish

We're excited to showcase even more trainees next week at a student organized symposium
Farncombe trainees will host visiting PhD students from Wageningen University & Research @WUR #Toxicology group for presentations, posters, and networking!
Registration is open until monday!

Honoured to be part of the @Bercik_Collins and have the privilege to be mentored by Dr. Collins!!
Congratulations to Dr. Steve Collins, well deserved recipient of the American Gastroenterological Association BCID Mentor of the Year award. A huge honour for an academic giant. @AmerGastroAssn @DDWMeeting @McMasterU @Farncombe_GI @CanGastroAssn @getgutsycanada Wonderful reviews by Elena Verdu, Premsyl Bercik and Bruce Vallance.

A lot of what looks like microbial engraftment after FMT might actually be noise. Using placebo sequencing and culture-enriched metagenomics, we sort signal from noise. Our latest from the Surette lab: nature.com/articles/s41467-0…

I’m excited to have contributed to an important article in @Nature about the global impact & trends of IBD. Understanding the evolution of IBD across epidemiologic stages enables healthcare systems to better anticipate the future worldwide burden of IBD. nature.com/articles/s41586-0…

We are honoured to bestow the Distinguished Service Award to Dr. Wallace MacNaughton — one of two recipients for 2025. Thank you for your invaluable contributions the CAG and the GI field! #CAGawards2025
A new paper from @Bercik_Collins accepted and published after many, many years of work in BBI. It's great news. @KraimiNarj27924 Vivek Philip @Farncombe_GI @Giada_DePalma Chiko Shimbori and all collaborators.

Fantastic talk by Dr. Madhusudan Grover @mgrover_gi from @MayoClinic on the role of proteases in post-infectious IBS at today's noon rounds. Great to see the trainees so engaged!
I’m honored to have my work selected for an oral presentation in the CAG student paper prize and to have received a CAG postdoctoral award. It was a great congress to foster collaboration for my final year of the postdoctoral fellowship. @cddwclm2025 @Bercik_Collins @MacDeptMed

Great pleasure to present at GI Research topics 2025 @cddw_clm. A lot of interactions. Now than ever…the importance of #communicating #science. Thank you. @VeroGirouxPhD, chair, for the invite. @UM_RadyFHS @um_research @umanitoba @Research_MB

A new study published in @Nature reveals how enterochromaffin (EC) cells contribute to chronic pain in #IBS and #IBD. The research identifies two types of EC cells that trigger pain signals, paving the way for more targeted treatments. medicalxpress.com/news/2025-…

Our manuscript on sex in #IBD is online @NatRevGastroHep 🥳
Using my prior experience with grad reading courses @UAlberta_FoMD, @JEGhia PhD student Diane Tshikudi & I helped launch @UM_Immu IMMU7090 & Diane's exceptional classwork resulted in publication!

📢#Serotonin Lovers
🚨Fascinating study ⏩Topological segregation of stress sensors along the gut crypt–villus axis‼️
👉Spatiotemporal dynamics of gut serotonin @Nature 🆕🔥
🎯Topological segregation of serotonergic #Enterochromaffin cell functionality along the mucosal architecture constitutes a mechanism for the #surveillance, #maintenance & #protection of gut #integrity under diverse physiological condition🙌
⏬Dive into to learn more about💡
✅Crypt & Villus Enterochromaffin Cells are Distinct Stress Sensors in the Gut
✅Two modes of serotonin release
🎯Villus EC cells release serotonin along with ATP, which activates nerve pathways that send pain signals to the brain🧠⚡️
🎯Crypt EC cells exhibit a tonic low-level mode that activates epithelial serotonin #5HT4 receptors to modulate basal ion secretion & a stimulus-induced high-level mode that activates #5HT3 receptors on sensory nerve fibres✨
