FIGURE 5.
Blocking both IL-9 and CD1d produces no further reduction in the number of pulmonary MCp. A, BALB/c WT and IL-9−/− mice were sensitized and half were treated with control Ig and the other received anti-CD1d just before challenge with aerosolized Ag as indicated. The mean (±SE) concentration of MCp/106 MNC from six, seven, eight, and nine mice in each group, respectively, is presented. B, BALB/c WT and CD1d−/− mice were sensitized and half were treated with control Ig and the other received anti-IL-9 just before challenge with aerosolized Ag as indicated. The mean (±SE) concentration of MCp/106 MNC from four, five, four, and six mice in each group, respectively is presented.
