Hepatitis C virus–specific CD8+ T cells restricted by donor HLA alleles following liver transplantation
George M. Lauer – 22 June 2005 – By necessity, human liver transplantation is performed across HLA barriers. As a result, intracellular infection of the allograft presents a unique immunologic challenge for the recipient's immune system. In this study, we describe the presence of HLA‐A2‐restricted, hepatitis C virus (HCV)‐specific CD8+ T cells in liver transplant recipients in whom the allograft is HLA‐A2 positive and the recipient is HLA‐A2 negative. These memory‐effector T cells are recipient derived and recognize HCV peptide uniquely in the context of HLA‐A2.
