Official title: The role of microbiota specific T cells in Inflammatory Bowel Disease

Funded at Icahn School of Medicine at Mount Sinai · NIH-11340316 · Data updated 2026-11-12

A doctor-science team will study how the body's T cells that recognize gut microbes relate to inflammatory bowel disease in people and in a humanized mouse model.

Who could benefit from this research

Could help

Adults with Crohn’s disease or other inflammatory bowel diseases who are being considered for anti-IL-23 therapy and healthy controls.

Less likely to help

Patients not eligible for anti-IL-23 therapy or those without access to advanced sequencing studies may have no direct benefit.

What this research studies

This project will use cutting-edge single-cell RNA and TCR sequencing to track T cell types and clonotypes over time in people with Crohn's disease who do or don’t respond to anti-IL-23 therapy, compare them with healthy controls, and study similar processes in humanized mice. By following how these T cells change before and after colitis induction, researchers aim to identify specific TCRs and cell states linked to disease activity. The findings could guide the development of targeted, antigen-specific therapies for IBD. The work combines patient samples and advanced animal models to map immune responses at high resolution.

Why it matters

Potential benefit: If successful, this could lead to precision therapies that target disease-causing T cells in IBD, potentially reducing reliance on broad immunosuppressants.

How similar studies have gone: Previous similar approaches identified antigen-specific antibodies and T cell patterns in autoimmune diseases, suggesting this strategy could reveal actionable targets in IBD.
