Production of intracellular cytokines in bone marrow-derived dendritic cells (BMDC). The percentage of BMDC positive for interleukin (IL)-4 (a), IL-10 (b) or IL-12 (c), represented as the mean ± standard error of the mean (s.e.m.) obtained from three to four experiments of the type shown in Fig. 4, are shown for days 3, 8 and 13 BMDC. BMDC were either unpulsed or pulsed with rV + rF1 (peps) for 24 h. Paired t-test statistical analysis was used. The increases of IL-4 and IL-12 were significant overall (P < 0.05) at day 8.
