HDM exposure results in increased total IgE and HDM-specific IgG₁.

<p>Adult female BALB/c mice were exposed to 25 μg of HDM protein (or control) daily for 10 days. On day 9 they were infected with 1×10⁸ TCID₅₀ HRV-1B or inactivated virus. Samples were harvested 48 hours after infection. HDM exposure resulted in increased total IgE (A) and HDM-specific IgG₁ (B), however there were no effects of HRV-1B infection, or the combination of HDM exposure and HRV-1B infection on serum antibodies. * indicates a significant difference between groups. <i>n</i> = 8 to 10 per treatment.
