However, anti-IL-8 or anti-GM-CSF blocking antibodies failed to reduce the ESEA in these supernatants, suggesting involvement of other mechanisms. This study suggests that in sensitized individuals, allergen may contribute to polyp eosinophilia by stimulating the production of granulocyte/macrophage colony stimulating factor and interleukin 8.
