How gut immune cells and microbes affect colorectal cancer

Innate lymphoid cell regulation of the host-microbiota interactions in cancer

NIH-funded research Weill Medical Coll of Cornell Univ · NIH-11161618

This project looks at whether a type of gut immune cell helps control gut bacteria to slow colorectal cancer and make immunotherapy work better.

What this research studies

If you have colorectal cancer, this research looks at immune cells called ILC3s in the gut to see how they control the bacteria living there and affect tumor growth. The team will analyze tumor tissue and stool from patients and use laboratory models to track how ILC3s change during cancer and during immunotherapy. They will test whether restoring normal ILC3-microbiota interactions can reduce inflammation, slow tumors, and improve responses to checkpoint inhibitors. The goal is to find new treatment strategies or markers to help decide who will benefit from immunotherapy.

Who could benefit from this research

Good fit: Ideal candidates would be people with colorectal cancer who can provide tumor tissue and stool samples, especially those receiving or planning to receive immunotherapy.

Not a fit: People without colorectal cancer or patients whose cancers are unrelated to gut microbiota interactions are unlikely to gain direct benefit from this project.

Why it matters

Potential benefit: If successful, this work could lead to new ways to boost immunotherapy and slow colorectal cancer by targeting gut immune cells or the microbiota.

How similar studies have performed: Prior human and animal studies show gut microbes influence immunotherapy responses, but targeting ILC3-driven host-microbiota pathways is a newer approach with promising early data.
