How transplanted organs and bodies can speed up or slow down aging

Understanding Interorgan Communication Through Heterochronic Organ Transplantation

NIH-funded research Brigham and Women's Hospital · NIH-11299011

This project looks at whether organs from older or younger donors change the biological aging of the transplanted organ and the recipient, which could matter for people getting organ transplants.

What this research studies

From a patient's view, researchers want to know if receiving an older or younger organ changes how your body or the graft ages. They will use age-mismatched transplants in lab models and examine tissues and blood for molecular aging markers, immune changes, and signs of senescent cells. The team will connect these lab findings with clinical transplant scenarios by working with transplant clinicians and analyzing patient-relevant data. Their measurements include biological age biomarkers and functional outcomes to understand risks and potential protective strategies.

Who could benefit from this research

Good fit: Ideal candidates are people listed for or having received organ transplants who can provide clinical data or biological samples and attend follow-up at participating centers.

Not a fit: People who do not need organ transplants or whose conditions are unrelated to transplant biology would not directly benefit from this project.

Why it matters

Potential benefit: If successful, this work could help doctors reduce rejection, improve donor–recipient matching, and protect patients' long-term health by addressing organ aging.

How similar studies have performed: Previous animal studies, including preliminary work from this team, show donor and recipient age can change organ biology, but applying these findings to human care is still largely untested.
