Fighting intestinal infections with the body’s own endocannabinoids — ScienceDaily

Endocannabinoids, signaling molecules produced in the body that share features with chemicals found in marijuana, can shut down genes needed for some pathogenic intestinal bacteria to colonize, multiply, and cause disease, new research led by UT Southwestern scientists shows.

The findings, published online today in Cell, could help explain why the cannabis plant — the most potent part of which is marijuana — can lessen the symptoms of various bowel conditions and may eventually lead to new ways to fight gastrointestinal infections.

Discovered in 1992, endocannabinoids are lipid-based neurotransmitters that play a variety of roles in the body, including regulating immunity, appetite, and mood. Cannabis and its derivatives have long been used to relieve chronic gastrointestinal conditions, including irritable bowel syndrome and inflammatory bowel disease. Studies have shown that dysregulation of the body’s endocannabinoid system can lead to intestinal inflammation and affect the makeup of gut microbiota, the population
