Scientists collect blood samples to unlock secrets of immune rebuilding after transplant

NCT ID NCT02129543

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study collects blood samples from up to 700 people, including stem-cell transplant patients and their donors, to understand how the immune system recovers after transplant. Researchers will analyze immune cells and T cell subsets to learn about immune reconstitution and graft-versus-host disease. No treatments are being tested; the goal is to gather information for future research.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If successful, this research could help doctors understand how to improve immune recovery after stem-cell transplants, potentially leading to better outcomes for patients.
What could go wrong
This is an observational study, not a treatment trial. It collects samples for research, so there is no direct benefit to participants. The findings may not lead to new therapies for many years.
