Figure 4.

Immunoglobulin E (IgE) protein levels from blood plasma (A) and IgE pulmonary gene expression levels (B). Plasma IgE levels were measured to characterize the systemic allergic response and are expressed as nanograms of IgE per milliliter of plasma (ng/mL). Pulmonary IgE gene expression levels are shown as relative expression to Gapdh housekeeping gene. Data are presented as mean ± SEM (n = 3–4 mice/group). Plasma IgE protein levels were analyzed in duplicate (A). Bars indicate a significant difference of P < 0.05 between groups.
