Dr. Chris Nguan
Manager, Kidney Transplantation and Immunology Center
The Centre for Kidney Transplantation and Immunology is a leader in advancing kidney transplantation through cutting-edge research, clinical innovation, and a commitment to equity in access and allocation. With expertise spanning immune function, diagnostics, and therapeutics, the Centre collaborates with key provincial partners to improve transplantation outcomes across British Columbia. Research focuses on understanding immune responses, microbiome influences, and novel therapeutic approaches, including ex-vivo graft modification and xenotransplantation. By integrating artificial intelligence and machine learning, the Centre continues to refine transplantation processes, driving innovation and ensuring long-term graft survival for patients.
The Center for Kidney Transplantation and Immunology is centrally positioned to provide core competence in all facets of Immune function, diagnostics and therapeutics. In the domain of Kidney Transplantation, our investigators include clinicians in urologic transplantation and nephrology, transplant pharmaceutical sciences, transplant infectious disease and critical care, amongst others. Through strong collaborations, these translational efforts are supported by the Provincial HLA lab located in Vancouver General Hospital, the Provincial Kidney Care Pharmacy, the Provincial Renal Agency, and BC Transplant Society. The Kidney Transplant Program is a Provincial Program administered by PHSA and covers all 5 Regional Health Authorities where the central transplant centers are located at VGH and SPH in Vancouver. Therefore, patients from all over the British Colmbia and beyond are provided critical clinical services at VGH, where they are then offered participation in many studies and trials which involve this core Research Center.
Our work seeks to continue to determine the mechanistic elements underlying the immune system’s response to foreign antigen which determine the fate of transplanted allogenic cells, tissues and organs into human patients. As well, there are many influencing factors on the immune system which have come to be recognized as increasing importance, which alter the phenotypic milieu and interactions between self and non-self tissues. These include the microbiome, the intrinsic nonself commensal organisms that live within and are extrinsic to, the human body which intimately affect how we perceive, process and react to the outside world, the rise of glyco-reactive species on the surface of cells which have been demonstrated to have increasing importance in allorecognition and which appear to be amenable to experimental manipulation.
Artificial intelligence and Machine Learning techniques are increasingly used in the domain of Kidney Transplantation, given the extreme complexities of accounting for input donor and organ variables, procurement and logistics, implantation complications and hemodynamics, recipient baseline factors and the influence of immune suppression and residual immune reactivity on outcomes. With success rates greater than 95% and standard 20 year graft survival outcomes, incremental gains come with continuous ML derived insights into optimizations along the chain of care. The center continues to develop and refine AI and machine learning methods to analyse the rich data intensive environment which is kidney transplantation and immunology.
