Fig. 3. In B10.TCRδ−/− mice, the frequency of CD8+ T cells producing inflammatory cytokines is elevated.
Spleen cells were stimulated with PMA/ionomycin for 4 hours at 37°C in the presence of Brefeldin A. After surface staining with anti-CD3, anti-TCR-β, anti-CD8, and anti-CD4 mAbs, cells were fixed and permeabilized, and then stained with the indicated anti-cytokine mAb. The percent of CD3+ TCR-β+ CD8+ or CD3+ TCR-β+ CD4+ cells staining with each anti-cytokine mAb was determined by flow cytometric analysis. Means obtained from 4 five week-old female mice per group are shown; error bars indicate SEM.
