At a Glance

More than 25,000 kidney transplants are performed annually in the United States. However, 92,000 individuals remain on the kidney transplant waitlist. Repeat transplants often have worse health outcomes, so preventing graft failure after the first transplant is crucial. Acute rejection (AR) is a major cause of failure, but there is still a lack of understanding of its causes and reliable, noninvasive ways to detect it. This study aims to better understand the pathophysiology of AR and identify noninvasive biomarkers. Modification of donor-derived cell-free DNA (dd-cfDNA) presents a promising target for early diagnosis and supports the development of more effective therapies.
