Analysis of costimulatory and memory cell‐surface markers in chronic HCV, vaccinated, and SR volunteers. (A,B) Thawed PBMCs were costained with MHC class II tetramers and anti‐CD127 and ‐CD28 antibodies in chronic HCV patients, vaccinated volunteers at different trial time points, and in SR persons. (C) Proportion of tetramer⁺ cells expressing Tcm, Tem, Temra, and Tscm phenotype in the same cohorts. All tetramer staining and phenotyping were performed ex vivo. Error bars represent the SEM. Only statistical differences are shown.
