Stuart Johnston Knechtle

William R. Kenan, Jr. Distinguished Professor of Surgery
Surgery, Abdominal Transplant Surgery

Overview


During my career as an academic surgeon, I have had the privilege of leading and/or participating in a diverse portfolio of hypothesis-driven research projects.  These projects have centered on the immunology of surgery and transplantation, including both cellular and antibody-mediated immune responses.  During my training I studied the response of hyper-sensitized recipients to allogeneic liver transplantation, and am currently studying means of reducing immunologic memory that might allow more successful transplantation in sensitized recipients.  This immune response involves pathways of coagulation, antibody-mediated rejection, and cellular rejection and current work in my lab involves these three pathways.  The other major focuses of my work have been co-stimulation blockade and immune cell depletion as approaches to immunologic unresponsiveness or tolerance.  My research group has been involved in translational and clinical research to develop these mechanistic tools for the benefit of human organ transplant recipients.

Journal Article Am J Transplant · October 22, 2025 Antibody-mediated rejection (AMR) remains a significant barrier to successful outcomes in both allo- and xenotransplantation. In this study, we investigate the efficacy of a novel recombinant endopeptidase, IceMG, which simultaneously cleaves IgG and IgM i ... Full text Link to item Cite

Transforming the logistics of liver transplantation with normothermic machine perfusion: Clinical impact versus cost.

Journal Article Liver Transpl · June 1, 2025 Normothermic machine perfusion (NMP) facilitates the utilization of marginal liver allografts. It remains unknown whether clinical benefits offset additional costs in the real-world setting. We performed a comparison of outcomes and hospitalization costs f ... Full text Link to item Cite

The Role of Sleep Apnea in Postoperative Neurocognitive Disorders Among Older Noncardiac Surgery Patients: A Prospective Cohort Study.

Journal Article Anesth Analg · January 1, 2025 BACKGROUND: Obstructive sleep apnea is associated with increased dementia risk, yet its role in postoperative neurocognitive disorders is unclear. Here, we studied whether the severity of untreated obstructive sleep apnea is associated with the severity of ... Full text Link to item Cite
