Preventing and repairing gut injury after bone marrow transplant

Cellular and Molecular Studies of Bone Marrow Transplant

NIH-funded research Icahn School of Medicine at Mount Sinai · NIH-11191449

Lab discoveries about how the immune system damages gut stem cells are being turned into new treatments to help people with severe gut graft-versus-host disease after an allogeneic bone marrow transplant.

What this research studies

You would be part of a program that studies why the intestine is so badly harmed by immune attacks after a donor bone marrow transplant and how to help it heal. Researchers are focusing on intestinal stem cells and key molecules like the mitochondrial enzyme SDHA and the signaling protein RIPK1 to understand how damage happens and how to restore regeneration. The work combines lab models with analysis of patient gut biopsies and shared clinical cores. Promising lab findings are being moved into Phase 2 clinical trials that patients may join to test therapies aimed at protecting or repairing the gut.

Who could benefit from this research

Good fit: Ideal candidates are people who have had an allogeneic hematopoietic cell (bone marrow) transplant and are developing or have acute gastrointestinal graft-versus-host disease or are at high risk for it.

Not a fit: People without GI involvement after transplant, those with unrelated medical conditions, or patients who do not meet trial safety criteria may not benefit or be eligible.

Why it matters

Potential benefit: If successful, this work could reduce severe gut GVHD, lower deaths after transplant, and allow more patients to safely receive curative allogeneic transplants.

How similar studies have performed: Related laboratory studies and early-phase clinical work have shown some promising approaches to protect gut stem cells, but effective treatments for steroid-resistant GI GVHD remain limited.
