Table 2 Effect of inhaled dust extract on serum antibody production in mice.

Treatment IgE (×105 U/ml) IgG1 (×105 U/ml) IgG2a (OD405)
PBS 2.7 (1.7–5.6) 11.1 (8.1–19.6) 0.15 (0.13–0.27)
LPS 2.2 (1.3–5.6) 13.3 (8.4–26.7) 0.14 (0.13–0.3)
Dust extract 1.3 (0.9–2.0), p = 0.017 5.5 (2.0–8.1), p = 0.001 0.17 (0.13–0.2)
Non‐sensitised 0 0 0.09

PBS, phosphate buffered saline; LPS, lipopolysaccharide.

Serum levels of OVA specific IgE, IgG1, IgG2a were measured by ELISA and expressed as arbitrary units; n ⩾8 per group. The results are presented as median with the 25–75th percentile in parentheses. Dust extract treated mice were compared with PBS treated mice by the two tailed Mann‐Whitney test.
