Subversion of effector CD8+ T cell differentiation in acute hepatitis C virus infection: the role of the virus.

In a companion study, we showed a dichotomy between the expansion of central memory (CCR7(+)) hepatitis C virus (HCV)-specific CTL and the incomplete memory effector differentiation in patients with acute HCV infection. Indeed, effector cells were unable to perform immediate functions, despite expressing the tissue-homing phenotype of effector memory cells… (More)
