Figure 3.

Effects of IL-5 priming on the generation of TNF-α, IL-5, IL-13, MIP-1α, and GM-CSF 6 h after anti-IgE activation of sensitized hMC. (A) Results are expressed as pg/10⁶ hMC and are the mean ± SEM of five experiments (except for IL-13, where n = 3). Note differences in scale. (B) Comparison of IL-4 and IL-5 priming effects for each cytokine. The results are expressed as a percentage of the amounts of each cytokine generated by hMC maintained in SCF alone (control) and are the mean ± SEM of five experiments, except for IL-13 (n = 3 for IL-5 priming; n = 4 for IL-4 priming).
