Excited to share our new study in Cell Host & Microbe!

We show that bacteria in human saliva and the small intestine can metabolize peanut allergens, reducing IgE binding and anaphylaxis.

Patients with higher peanut tolerance harbor more of these microbes. 1/2

Microbiota impact peanut allergy

Saliva & jejunum harbor peanut-degrading bacteria(Rothia) that metabolize immunodominant PN allergens. Mice colonized w/Rothia show ⬇️anaphylaxis & allergic patients w/better PN tolerance have ⬆️abundance of these bacteria

Congrats to Dr. @LiamERondeau from @LabCaminero for winning the Junior Investigator Award! 🦠

Tryptophan is an essential amino acid found in protein-rich foods and cruciferous vegetables 🥦. Dr. Rondeau highlighted the protective role of microbial tryptophan metabolism in mouse models of IBD, with potential applications in dietary interventions in IBD care.

Microbial metabolism of food allergens determines the severity of IgE-mediated anaphylaxis @R_JimenezSaiz @LiamERondeau @Elisaaasm @cam

[Caminero Lab @LabCaminero]

These findings highlight the potential of targeting microbial proteolytic activity or PAR2 signaling to alleviate inflammation in IBD patients. #IBDResearch #Microbiome #GutHealth @VerduLab @BrunaBLuz (5/5)

🧪NEW PAPER ALERT🧪

Check out our paper in Gut Microbes that sheds light on the role of proteolytic bacteria in inciting inflammation during #colitis, led by @LiamERondeau, the lab's first grad student @FarncombeGI @McMasterU #IBD
Check it out here👇

Using gnotobiotic and conventional mouse models, we demonstrate that proteolytic microbes that activate PAR2 expand during inflammation, thus worsening colitis through a PAR2-mediated feedback loop. (⅘)
