Serum samples from mice in the three experimental groups were analyzed to determine the HDM-specific IgE levels (a), HDM-specific IgG1 levels (b), and HDM-specific IgG2a levels (c) by ELISA. The data are expressed as the mean ± SD of the values obtained for the individual mice. n = 5–6 mice per group. *P < 0.05Back to article page
