The CD8 preimmune repertoire is defined as the set of circulating antigen-specific T CD8 lymphocytes that have not been activated yet by their cognate antigen. Because those cells are very rare, they have not been evaluated in humans. We developed a tetramer-based enrichment protocol that allowed for the first time direct detection and enumeration of those rare naive antigen-specific CD8 T cells in healthys. We then used this tool to characterize the CD8 preimmune repertoire in patients with chronic hepatitis C viral infection. We found that their naive CD8 T cells are dysregulated, being hypersensitive to TCR signals, and with increased proportions of memory-phenotype (MP) cells in inexperienced populations. These perturbations are reversi...
