Treatment of HConEpiC with IL-13 or IL-4 alone resulted in an increase in the levels of the allergy-related chemokine eotaxin-3 in the conditioned media at all three doses tested for IL-4 and the highest two doses for IL-13 (10 and 100 ng/ml) after 24 h (Figure 1). Here, CCL26 is linked to allergic disease.
