How bile acids and the FXR receptor control immune cells in the gut

The regulation of gut macrophage’s function by the bile acid receptor FXR

NIH-funded research University of Wisconsin-Madison · NIH-11353870

This project will learn how bile acids and their receptor FXR change gut immune cells in people with inflammatory bowel disease who are at risk for colitis-associated colorectal cancer.

What this research studies

From my point of view as a patient, the team wants to understand how bile acids and the FXR receptor shape the behavior of gut macrophages, the immune cells that watch over the intestine. They will use lab-grown cells and 3-D gut models plus animal experiments to recreate inflammation and early cancer changes and to track FXR signaling. The researchers will also study how damaged gut lining and ongoing inflammation upset bile acid balance and weaken FXR responses. Ultimately they aim to map how gut macrophages, FXR, and other cell types interact during colitis-associated colorectal cancer development.

Who could benefit from this research

Good fit: Ideal candidates would be people with ulcerative colitis or other long-standing inflammatory bowel disease who are at increased risk for colitis-associated colorectal cancer.

Not a fit: People without inflammatory bowel disease or those with typical sporadic colorectal cancer are less likely to benefit directly from this specific line of research.

Why it matters

Potential benefit: If successful, this work could point to new ways to detect or treat inflammation-linked colon cancer in people with long-standing IBD.

How similar studies have performed: Prior research has linked bile acids and FXR to gut health, but defining how FXR controls gut macrophages during colitis-associated cancer is a more recent and relatively novel area.
