Immunophenotyping of DCs stimulated to mature with TNF-α.

(A) Representative example of DCs (day 7) of a healthy donor (left panels), a patient with chronic HCV infection (middle panels), and a patient whose HCV infection resolved (right panels). Surface expression of the indicated markers (shaded areas) are overlaid with isotype control staining (gray line). (B) Cumulative flow cytometry data on 15 patients with chronic HCV infection (▪) and 13 healthy donors (■). Data are expressed as mean percentage of positive cells ± SD (left panels) and mean fluorescence intensity ± SD (right panels). *P ≤ .01 between the 2 groups.
