CCR4 induces Th1 polarization upon CVB5 infection. C57BL/6 and CCR4−/− mice were infected with CVB5 (AD). (A,B) The production of IFN-γ and IL-17 by CD4+ and CD8+ T cells was evaluated at day 7 post infection by flow cytometry after ex vivo stimulation with PMA and ionomycin in the presence of brefeldin-A. (C) IFN-γ and IL-17 were measured in the pancreas homogenate by ELISA at day 7. (D) C57BL/6 mice were treated on days −1, 1, 3 and 5 with anti-CCL17 antibody, and the expression of ifng and il17 was evaluated in the pancreas at 7 days post-infection. (E) Survival of C57BL/6 (WT), IFN-γ−/− and IL-17−/− mice after CVB5 infection. N = 5–10 mice per group. The data are shown as the means + SEM from at least 3 independent experiments, and * indicates p < 0.05.
