PD-L1 May Serve as a Biomarker for Chimerism-Induced Tolerance in Kidney Transplant Recipients
A. Merchak,¹ A. Khalil,¹ A. Chhabra,¹ J. Leventhal,² S. Ildstad.¹
¹University of Louisville, Louisville, KY; ²Northwestern Memorial Hospital, Chicago, IL.
Durable chimerism is currently the most reliable biomarker of donor specific tolerance. Identifying and validating other predictive biomarkers is therefore a high priority. Since 2009…
