Gut bacterial lectins as a path to new live therapies for inflammatory bowel disease

Characterization of lectins to understand human microbiome functions and develop live biotherapeutics

NIH-funded research Icahn School of Medicine at Mount Sinai · NIH-11321561

What this research studies

Researchers will study a protein made by common gut bacteria (Cbeg5) to learn how it influences immune cells that live in the gut. They will use lab-grown human immune cells, animal models, and analysis of human microbiome samples to map which cells and pathways are affected. The team will test whether delivering this protein or bacteria that produce it can reduce gut inflammation in models of inflammatory bowel disease. They will also search the microbiome for other bacterial lectins that might similarly affect human immune responses.

Who could benefit from this research

Good fit: People with inflammatory bowel disease (Crohn’s disease or ulcerative colitis) who are interested in microbiome-based treatments would be the most relevant candidates.

Not a fit: People without gut inflammatory conditions or those seeking an immediate approved therapy are unlikely to benefit from this early-stage research.

Why it matters

Potential benefit: Could lead to new microbiome-based live therapies that reduce harmful gut inflammation in people with IBD.

How similar studies have performed: Other microbiome-based and live biotherapeutic approaches have shown promise in lab studies and early clinical trials, but using bacterial lectins like Cbeg5 as a therapy is a newer and largely untested idea.
