In the present study, we also investigated the chemokine ligand levels, that is, CCL11 (also known as eotaxin), and CCL24 (also known as eotaxin-2 or myeloid progenitor inhibitor factor-2), which are all epithelial cell–derived chemokines involved in the pathogenesis of asthma and rhinitis. The gene discussed is CCL24; the disease is asthma.
