Cannabinoid receptor 1 activity promotes microbial dysbiosis by stimulating the oxygen-dependent expansion of Enterobacteriaceae

Mary K. Mitchell, Mikayla A Carty, Nayeli L Snow…·Melissa Ellermann

This study shows that CB1 receptor activation promotes microbial dysbiosis by stimulating oxygen-dependent expansion of Enterobacteriaceae, leading to exacerbated colitis.

Human gut commensal Alistipes timonensis modulates the host lipidome and delivers anti-inflammatory outer membrane vesicles to suppress colitis in an Il10-deficient mouse model

Ethan A. Older, Mary K. Mitchell, Andrew Campbell…·Jie Li

This study shows that Alistipes timonensis colonization in Il10-deficient mice delays colitis by altering the host lipidome and delivering anti-inflammatory outer membrane vesicles containing immunomodulatory lipids.
