MHC Class II expression on stimulated basophils.

<p>Representative dot plots showing MHC Class II expression on basophils freshly isolated (A), and after 72 hours culture with medium alone (B) or IL-3 (10 ng/ml), IFN-γ and GM-CSF (100 ng/ml) (C). Corresponding isotype control (D). Percentage of MHC Class II positive basophils for individual atopic HDM-allergic (open shapes) and non-atopic (closed shapes) donors after 72 hours culture with various stimuli (E). Differences between groups were calculated with One-way ANOVA and Dunett's Multiple comparison post-test with IL-3 as the control group for complete data sets of the 6 donors, * p&lt;0.05, ** p&lt;0.01.
