IL-4 plays an important role in transfer-mediated AHR. Recipients received spleen cells (5 × 107) from SA-treated wild-type mice (TRSA), from OVA-sensitized wild-type mice (TROVA), from SA-treated IL-4-deficient mice (TRSA/IL-4-/-), or from OVA-sensitized IL-4-deficient mice (TROVA/IL-4-/-). AR was measured 4 days after the transfer (n = 6–8 per group). * p < 0.05 compared with PC200Mch of TRSA. # p < 0.05 compared with PC200Mch of TROVA.
