Figure 5

Cytokine response in PBMC and BAL of controllers, progressors and uninfected animals after polyclonal stimulation. Percentage of polyfunctional cells and total cytokine secreting cells after SEB stimulation in the CD4+ memory T-cell subset of PBMC (A) and BAL (B) as well as in the CD8+ memory T-cell subset of PBMC (C) and BAL (D) in controllers, progressors and uninfected animals. Polyfunctional cells were defined as expressing two or three cytokines (IFN-γ+ TNF-α+, IFN-γ+ IL-2+, TNF-α+ IL-2+, IFN-γ+ TNF-α+ IL-2+) and the total response comprises polyfunctional cells and cells secreting one cytokine only (single positive cells). Horizontal lines represent the mean of each group and P-values were calculated with the Mann-Whitney's U-test (*P < 0.05 and **P < 0.01).
