The present study was designed to evaluate the expression and localization of eotaxins, which are well known to be potent and selective chemoattractants for eosinophils in CRS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design:<\/jats:title><jats:p>Randomized study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p>The patients were classified into eosinophilic and noneosinophilic groups. Histopathological profiles of the nasal polyp were observed with hematoxylin\u2010eosin staining. Eotaxin\u20101, \u20102, and \u20103 were immunohistochemically stained in the nasal polyps. Furthermore, the protein content of eotaxin subtypes inside the nasal polyp and sinus effusion was measured using enzyme\u2010linked immunosorbent assay (ELISA).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>In the nasal polyps, immunoreactivities of the eotaxin subfamily, eotaxin\u20101, \u20102, and \u20103, were noted in most of the infiltrating eosinophils, as well as in other inflammatory cells, epithelial cells, and endothelial cells. Compared with noneosinophilic CRS groups, eosinophilic CRS groups had a significant expression of eotaxins in their eosinophils. The eotaxin concentrations of nasal polyp and sinus effusion as measured by ELISA were significantly increased in the eosinophilic CRS group compared to the noneosinophilic CRS group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p>The present findings suggest that enhanced eotaxin family production by eosinophils results in the recruitment of eosinophils into the tissue by a self\u2010amplifying process.
