  • a Characteristics of 14 patients with detectable HCV-tetramer-positive CD8+ T cells are shown. A total of 56 patients were tested for significant frequencies of HCV-tetramer-positive CD8+ T cells. *, alanine aminotransferase (ALT) levels from an early and a late time point are shown for patients with acute HCV infection. **, patients were tested with a pool of all available HLA-A2-restricted tetramers because of the low frequencies of HCV-specific CD8+ T cells. GE, genome equivalents; ID, patient identification number; tp, pooled tetramers. M, male; F, female.

  • b Liver biopsies were analyzed using the Desmet classification (expressed as degree of inflammation/degree of fibrosis).
