Cleveland Clinic researchers have discovered a new bacterium that weakens the immune system in the gut, potentially contributing to certain inflammatory and infectious gut diseases.
The team identified the bacterium, Tomasiella immunophila (T. immunophila), which plays a key role in breaking down a crucial immune component of the gut’s multi-faceted protective immune barrier.
Identifying this bacterium is the first step to developing new treatments for a variety of inflammatory and infectious gut diseases. These conditions, including inflammatory bowel disease, Crohn’s and ulcerative colitis, are associated with decreased levels of secretory immunoglobulin A (SIgA), an antibody that protects mucosal surfaces.
