Figure 5. Strong correlation between cytokine secretion and expression of CD127 (A) but not PD-1 (B) early after HCV-challenge.

Figure 5

Vaccine-induced tetramer+ T cells are indicated by filled symbols and infection-induced T cells of the control chimpanzees are indicated by open symbols. The infection-induced NS31359-specific tetramer+ T cells in the vaccinated chimpanzee 95A014 (indicated by half filled, half open circles) did not display the CD127 phenotype and superior cytokine production of the vaccine-induced tetramer+ T cells but instead resembled the infection-induced T cells of the control chimpanzees.
