Understanding Organ Rejection After Transplant Using Tiny Organ Models
Vascularized liver-heart on-a-chip modeling antibody-mediated rejection and tolerance of allografts
This project aims to create miniature organ models to better understand why some transplanted organs are rejected by the body's immune system.

What this research studies
Organ transplantation offers a new lease on life for many, but it often requires lifelong medication to prevent the body from rejecting the new organ. Even with these medications, some patients develop donor-specific antibodies that can lead to a serious problem called antibody-mediated rejection, causing the transplanted organ to fail. This project will develop a new 'organ-on-a-chip' technology, combining tiny liver and heart models, to study how these antibodies cause rejection. By creating these advanced models, we hope to uncover the specific ways antibodies harm transplanted organs.
Who could benefit from this research
Good fit: This foundational research is relevant to patients who have received or may receive organ transplants, particularly those at risk for or experiencing antibody-mediated rejection.
Not a fit: Patients not involved in organ transplantation or related conditions would not directly benefit from this specific research.
Why it matters
Potential benefit: If successful, this work could lead to a deeper understanding of organ rejection, potentially helping to identify patients at higher risk and develop new ways to prevent or treat rejection without relying solely on lifelong immunosuppression.
How similar studies have performed: While organs-on-a-chip models exist for various human organs, this project is novel in its aim to specifically model antibody-mediated rejection in a multi-organ system.
