Figure 1. Late and transient appearance of HCV-specific CD8 T cells in mock-vaccinated control chimpanzees during HCV-challenge.

Figure 1

Serum HCV RNA titers (filled diamonds) and ALT levels (open squares) have previously been reported 12 and are shown for reference purposes. HCV RNA titers became undetectable by quantitative and qualitative PCR for three chimpanzees (A–C), but remained just above the detection limit for chimp 97A015 (marked by *, D). Error bars represent the standard error of the mean from 3 experiments. The HCV protein and first amino acid position of the epitope presented by the tetramer is indicated in each panel
