Targeting VLDLR to prevent both GvHD and leukemia relapse
Funded at Washington University · NIH-11339890 · Data updated 2026-11-12
A new approach using the VLDLR target aims to prevent graft-versus-host disease while keeping the anti-leukemia effects after allogeneic stem cell transplantation.

Who could benefit from this research
✓Could help
Patients who are candidates for allogeneic hematopoietic cell transplantation and at risk for GvHD or leukemia relapse.
✕Less likely to help
Patients not undergoing allo-HCT or those with conditions not related to GvHD or relapse may not benefit.
What this research studies
This project explores a way to separate the good graft-versus-leukemia effect from the harmful graft-versus-host disease in people who receive donor stem cell transplants. Using a genome-wide CRISPR screen, researchers identified VLDLR as a potential target to block GvHD without losing GvL. The work combines animal studies and human data to test how blocking VLDLR affects T cells and transplant outcomes. If successful, this could lead to therapies that reduce transplant complications and improve relapse control.
Why it matters
Potential benefit: If successful, patients could experience fewer transplant-related complications and better long-term control of leukemia.
How similar studies have gone: Preclinical work and early human data suggest methods to separate GvHD from GvL, but this specific VLDLR-targeting approach is novel.
