Apoptotic donor white cells to help kidney transplant tolerance
Official title: Apoptotic Donor Leukocytes to Promote Kidney Transplant Tolerance
Funded at University of Minnesota · NIH-11311943 · Data updated 2026-11-12
A new approach tests giving a few donor immune cells that are dying off, along with short-term immune drugs, to help kidney transplant patients accept a transplant long-term.

Who could benefit from this research
✓Could help
Ideal candidates are people with living-donor kidney transplants who could benefit from reduced or tailored immunosuppression.
✕Less likely to help
Patients with conditions not related to transplant tolerance or those unable to undergo the proposed cell therapies may not benefit.
What this research studies
This project builds on prior work in monkeys showing that two small infusions of donor leukocytes, combined with brief immunosuppression, can create lasting transplant tolerance. In kidney transplant models, researchers will use high‑dimensional immune profiling to understand how the regimen works and to refine the protocol for safety and effectiveness. The study aims to translate these findings into a clinically usable approach that could reduce long-term immunosuppression needs for living donor kidney recipients. The work is conducted at the University of Minnesota with a focus on mechanisms, efficacy, and steps toward human application.
Why it matters
Potential benefit: If successful, this strategy could lead to safer, longer-lasting kidney transplant tolerance with less immunosuppression.
How similar studies have gone: Previous nonhuman primate studies showed durable tolerance; this project seeks to translate that success to a kidney transplant setting.
