Chronic Rejection Series: Heart Cardiac Allograft Vasculopathy

Cardiac allograft vasculopathy (CAV) is a leading contributor to late allograft failure, mortality, and morbidity after heart transplantation. The prevalence of moderate to severe CAV over time has not changed significantly, and CAV remains an important contemporary consideration in post–heart transplantation management. The diagnosis and surveillance of CAV include both established and emerging invasive and noninvasive modalities, with a growing interest in understanding microvascular function and coronary physiology.

CCL22-expressing Stem Cell–derived Islet Grafts Recruit Regulatory T Cells in Mice

Cell therapy using human donor or stem cell–derived islets (SC-islets) to replace lost insulin-producing beta (β) cells holds great promise for type 1 diabetes. Recruiting regulatory T cells (Treg) through chemokine signaling could mitigate allo- and autoimmune attack on transplanted β-cells, potentially obviating the need for immunosuppressants. We hypothesized that SC-islets genetically engineered to secrete the chemokine C-C motif chemokine ligand 22 (CCL22) would attract Treg to the site of transplantation and may ultimately prolong graft survival.

Prolonged Skin Graft Survival and Histocompatibility in Highly Inbred Miniature Swine

Pigs are potential organ donors for humans. Some proposed xenotransplant tolerance regimens require genetically identical cells from different animals (eg, juvenile bone marrow and mature organs or tissues). We therefore sought to develop a highly inbred line of miniature swine for this purpose. The aim of this study was to test histocompatibility in a new subline of highly inbred miniature swine.

Optimizing Kidney Allograft Years: Underutilization of Pediatric Donors

The Kidney Donor Profile Index (KDPI) score drives kidney allocation in the United States for both adult and pediatric donors, despite the calculation being primarily derived from adult donor data. A KDPI of ≤20% is considered to have the longest graft survival potential and is typically prioritized for recipients who have a low Estimated Posttransplant Survival (EPTS) score. Using KDPI to assess pediatric donor quality may underestimate graft survival and result in underutilization of these kidneys for recipients with a low EPTS score.

The first ‘across the bridge’: Man who received experimental pig kidney transplant now has a human organ

Jan. 17 - One year ago, Tim Andrews was among the world’s first recipients of a genetically modified pig kidney. Now, he is the first in that small group of pioneers to go on to receive a human kidney

Odorico Lab Awarded Fall Research Competition Grant to Study How Engineered Stem Cell-Derived Islets Evade the Immune System

With the help of a new one-year, $70,000 grant from UW’s Fall Research Competition that will support the effort of Odorico lab member and Cellular and Molecular Biology PhD student Caterra Leavens, Odorico’s team will be extending their research into the immune evasive stem cell-derived islets they developed by studying exactly how these islets are able to avoid recognition and attack by the immune system.

A surgeon’s bold idea kept a newborn alive 16 months while she waited for a heart transplant

Jan 22 - Dr. Cleveland knew he needed a creative solution for Aaliyah to survive long enough to receive a donor heart. To come up with a plan, he consulted with a congenital heart surgeon at his hospital, someone he deeply trusted and respected: Dr. David Cleveland, his father. The resulting plan involved altering the anatomy of Aaliyah’s heart to create a path for blood to get to her lungs and body without going through her ventricles. This way, she would need just one VAD until she could get a transplant.

Bridge to Life wins FDA De Novo for transplant liver perfusion system

Jan 22 - Bridge to Life has received FDA De Novo clearance for its VitaSmart hypothermic oxygenated perfusion (HOPE) system for liver transplantation.=

Mistrust Fuels Drop in Deceased Organ Donations, Kidney Transplants

Jan. 16 - New federal data in the United States reviewed by the Kidney Transplant Collaborative show that 116 fewer kidney transplants were performed last year than in 2024. While that difference may seem small, experts are troubled by the decline.

Lab-grown kidney works in animals

Jan. 16 - As part of the research effort to develop lab-grown human organs to aid the study of kidney diseases and to mitigate the world transplant organ shortage, scientists have successfully produced the most sophisticated, bio-engineered kidney organoid to date. The newly created kidney organoid was successfully transplanted into mice, where it functioned and produced urine.

Invasive Fungal Disease in Transplantation: Prevention in a Shifting Landscape

Jan. 13 - nvasive fungal diseases remain a major cause of morbidity and mortality in patients undergoing transplant, with shifting epidemiology, emerging resistance, and geographic variation underscoring the urgent need for improved surveillance, prevention strategies, and antifungal stewardship.

MicroRNA Tests Eyed for Flagging Heart Transplant Rejection

Jan. 13 - The noninvasive diagnosis of allograft rejection after heart transplantation may be on the horizon, according to findings from the GRAfT cohort study. MicroRNA sequencing results, based on blood samples obtained at the time of an endomyocardial biopsy (EMB), were found to flag acute cellular rejection (ACR) and antibody-mediated rejection (AMR) after heart transplantation, according to Palak Shah, MD, MS.
