FIG. 5.

Expression of CD127 and KLRG1 on HCV-specific CD8⁺ T cells in blood and liver. (A) CD127 expression and (B) KLRG1 expression on HCV-specific CD8⁺ T cells derived from blood (PBMCs) or liver tissue (IHL) from chronically infected patients. Each circle represents one patient. Corresponding PBMC and IHL data from the same patient are connected by lines. Mean values are indicated by bars. The P value was calculated using a standard Student t test. Individual plots of patients C4 and C18 (CD127) as well as C5 and C6 (KLRG1) are shown below.
