IL-4, IL-5 and IL-13 levels following OVA-challenge. (A) Cytokine mRNA levels in pooled cultures of CD4⁺ T cells from OVA-treated C57BL/6, Ifnγ^−/− and Socs1^−/−Ifnγ^−/− mice were normalised against GAPDH mRNA (n≥3). (B) Cytokine production by cultured CD4⁺ T cells as measured by ELISA (n≥3). (C) Cytokine mRNA levels in lungs from saline and OVA-treated mice were normalised against GAPDH mRNA (n≥3). Bars represent mean ± S.E.M. * p < 0.05, ** p < 0.01
