How gut immune cells respond to foods and gut bacteria

Intestinal CD4 T cell responses to dietary and microbial antigens

NIH-funded research Rockefeller University · NIH-11262922

What this research studies

You will hear about research that examines specialized immune cells (CD4+ T cells) living in the gut lining and the tissue beneath it. Scientists track which parts of foods or bacteria these cells recognize by mapping their T‑cell receptors and following how individual cell clones expand or shrink. The team is also trying to find the gut T cells that specifically respond to food proteins and to understand how oral tolerance develops. Much of the work uses laboratory models and tissue or cell samples handled at Rockefeller University to connect antigen specificity with cell function.

Who could benefit from this research

Good fit: People with inflammatory bowel disease, unexplained intestinal inflammation, or suspected food allergies would be the most relevant candidates for related participation or sample donation.

Not a fit: Patients with non-immune structural GI problems or conditions unrelated to gut immune responses are unlikely to receive direct benefit from this research.

Why it matters

Potential benefit: If successful, this work could reveal specific gut immune targets to prevent or treat food allergies and inflammatory bowel diseases.

How similar studies have performed: Prior research established that CD4+ and regulatory T cells shape gut tolerance, but identifying food‑specific intestinal T cells and their clonal dynamics is relatively novel.
