Abstract
In the past decade, an explosion in the number of high-throughput tools for the measurement of different cellular products has occurred. These tools have the potential to further our understanding of human disease and this development has facilitated the identification of new biomarkers in all areas of medicine. In the field of solid organ transplantation, two different areas have developed: the use of biomarkers to predict allograft tolerance for the identification of patients who can be weaned from immunosuppressive therapy, and biomarkers for the prediction of allograft rejection, so that parenchymal damage can be prevented before it becomes irreversible. In this Review, we discuss the development of biomarkers that are indicative of transplant tolerance. Identifying patients in whom donor-specific tolerance has developed would constitute a major advance in the care of organ transplant recipients. This ability would allow the minimization or even the withdrawal of immunosuppressive therapy in selected patients, thus reducing the number of adverse effects and costs, and optimizing long-term graft outcomes. The routine clinical use of these biomarkers, once validated, would bring to the fore the possibility of personalized medicine.
