We describe two cases of hyperacute humoral rejection of living related kidney grafts despite negative pretransplantation T- and B-lymphocyte flow cytometric crossmatches and blood group identity. Retrospectively, antiendothelial IgG antibodies were detected on a panel of umbilical cord cells in the first case, and IgM antibodies against donor endothelial precursor cells were detected using a new endothelial cell crossmatch kit in the second case. Standard crossmatch methods using donor lymphocytes failed to detect these pathogenic antibodies and did not predict the danger of hyperacute rejection.

The human leukocyte antigen (HLA) system plays a critical role in transplant immunology, influencing outcomes through various immune-mediated rejection mechanisms. Hyperacute rejection is driven by preformed donor-specific antibodies (DSAs) targeting HLAs, leading to complement activation and graft loss within hours to days. Acute rejection typically occurs within six months post-transplantation, involving cellular and humoral responses, including the formation of de novo DSAs.

Recently, oncolytic virus (OV) therapy has shown great promise in treating malignancies. However, intravenous safety and inherent lack of immunity are two significant limitations in clinical practice. Herein, we successfully developed a recombinant Newcastle disease virus with porcine α1,3GT gene (NDV-GT) triggering hyperacute rejection.

A 31-year-old male patient with a history of sickle cell disease (SCD) with stage V chronic kidney disease (CKD) presented for a deceased donor kidney transplant. During surgery, the transplanted kidney showed mottling and limited cortical flow, raising concerns for an intraoperative sickle cell crisis versus hyperacute rejection. Postoperative imaging revealed decreased vascularity, and the patient was treated with RBC exchange.

Vascularized composite allotransplantation (VCA) represents a clinical challenge for transplant therapy, as it involves different tissues with unique immunogenicity. Even when receiving immunosuppressive therapy, they are more vulnerable to severe hypoxia, microvascular damage, and ultimately the rejection or chronic graft dysfunction after transplantation. This study aimed to develop a surgical protocol for VCA of the ear in a porcine biomodel in the absence of immunosuppression, maintaining the in vitro co-culture of the allograft and assessing their relationship with allograft survival.

Based on promising results obtained in primate models, pioneers in the US have now started to explore the new frontier of genetically-edited pig-to-human transplantation. The recent transition of xenotransplantation into clinical medicine has included transplants in brain-dead subjects and the compassionate use of xenotransplants in living recipients without options for allotransplantation. While the barrier of hyperacute rejection seems to be successfully overcome by gene editing of donor pigs, the occurrence of accelerated rejection could pose significant limitations to the success of the procedure.
