Figure 6.

Early-secreted antigenic target-6 and culture filtrate protein-10–specific responses, measured by IFN-γ ELISpot assay in bronchoalveolar lavage (BAL) mononuclear cells and peripheral blood mononuclear cells. (A) Paired BAL or blood frequencies of IFN-γ–producing T cells from HIV-1–infected (HIV⁺) and HIV-1–uninfected (HIV⁻) persons. (B) IFN-γ T-cell responses normalized to CD3 frequencies in BAL or blood. Zeros were set to a value of 1. Solid circles, blood; open squares, BAL. Differences were calculated using the Wilcoxon signed rank test. SFC = spot-forming cells.
