FIG. 5.

HCVpp entry into claudin-expressing hepatoma cell lines. Parental (XIN) and claudin-1-expressing (CL1), claudin-6-expressing (CL6), and claudin-9-expressing (CL9) H1H (A) or NKNT3 (B) cells were infected with HCVpp bearing subtype 1a (white bars) or 1b (hatched bars) envelope glycoproteins. Values are the means ± standard deviations of the results of four independent experiments. *, statistically significant increases in HCVpp entry compared to its entry in cells transduced by vector alone; P values were ≤0.04 as calculated by the two-tailed paired t test.
