CCL11 and allergic rhinitis: Similarly to IL-17, the meanserum levels of eotaxin increased in patients, increased transcription from eotaxin gene had been observed in the bronchial mucosa of asthmatic patients.19 Increased expression of eotaxin contributes to the chemotaxis of eosinophils to the site of inflammation.20 Our results showed that serum eotaxin levels had a negative correlation with pulmonary function in asthmatic patients with allergic rhinitis.
