Th2-type cytokines like IL-4, IL-5, IL-9 and IL-13 contribute to the pathophysiological conditions of allergy and asthma, and chemokines like eotaxin/CCL11, RANTES/CCL5 and monocyte chemoattractant proteins (MCPs) contribute decisively to the recruitment of basophil and eosinophil granulocytes as well as mast cells in tissues of allergic inflammation [14]. This evidence concerns the gene CCL11 and Allergy.
