Phenotypic characterization of lymphocytes after exposure to HCV in the presence or absence of TLP. Lymphoid cells from a healthy
donor were exposed in duplicate to CHC-1 or CHC-2 or to normal healthy human in the absence (untreated) or presence of TLP (TLP treated).
Cells were collected at 10 d.p.i., stained for CD3, CD4 and CD8 or with isotype controls, and analyzed by flow cytometry. Percentage CD4+ T cell
decrease and percentage CD8+ T cell increase was calculated based on CD4+ and CD8+ T cell frequencies (taken as 100 %) in control cultures
exposed to normal human plasma
