Cytokine expression by peripheral blood T cells and neutrophils. Cells were stimulated ex vivo and cytokine expression quantified by flow cytometry. Three factors including T-cell cytokine expression (left column), neutrophil cytokine expression (middle column) and a comparison between T cell and neutrophil cytokine expression (right column) were assessed for a IFNγ, b TNF, c IL-4, and d IL-10 expression. Uninfected animals (n = 4; uninf; blue circles), 2-week postinfection animals (n = 4; red circles), and 8-week postinfection infected (n = 4; green triangles) were examined. The Wilcoxon matched-pairs test was used for pairwise comparisons
