What this research studies

This research brings together teams to study why older transplant recipients react differently to donated organs compared with younger people. Scientists will look at immune cells (like T and B cells), antibodies, and supporting tissue cells to understand age-related changes that drive rejection or inflammation. The work combines lab studies on cells and tissues with samples and data from transplant patients to connect basic findings to real-world care. The aim is to identify age-specific targets that could lead to different immunosuppression or protective approaches for older patients.

Who could benefit from this research

Good fit: Ideal candidates would be older adults who are waiting for or have received an organ transplant and who are willing to provide medical information and biologic samples.

Not a fit: People without a need for organ transplantation or who are much younger may not directly benefit from the age-focused findings in this project.

Why it matters

Potential benefit: Could lead to transplant treatments adapted for older adults that lower rejection risk and reduce harmful side effects of current drugs.

How similar studies have performed: Prior research shows the immune system changes with age, but age-specific transplant strategies are largely untested and this program builds on emerging evidence.
