Percent change in ELISpot responses after depleting CD4+ or CD8+ T cells at 1 m time-point.

IFN-γ production by ELISpot assay was measured with and without depletion of either CD4+ or CD8+ T cell populations and is expressed as percent change in spot forming cells with depletion. A negative value indicated IFN-γ decreased by the indicated percentage after depletion, and a positive value indicated IFN-γ increased after depletion. All peptide pools tested in ELISpot depletion studies met criteria for positive in the absence of depletion (Figures 1 and 2). Any decrease or increase in ELISpot responses of ≥25% following depletion was scored as positive and a number is provided in the table, while changes <25% were scored as no change (NC).
