title: Increased eotaxin-mRNA expression in non-atopic and atopic nasal polyps: comparison to RANTES and MCP-3 expression.
abstract: Eosinophilic tissue infiltration of nasal mucosa typical for allergic rhinitis and chronic polypous sinusitis may be due to chemotactic activity of chemokines specific for eosinophils. The CC-chemokines eotaxin, RANTES and MCP-3 have been postulated to be involved in the recruitment of eosinophils to certain inflamed tissues. To explore their possible role in chronic polypous sinusitis we examined eotaxin-, RANTES- and MCP-3-gene expression in human nasal polyps and normal human nasal mucosa of patients undergoing endonasal surgery for treatment of chronic polypous sinusitis. Using gene-specific primers in semi-quantitative reverse-transcriptase polymerase-chain-reaction experiments we found elevated expression of eotaxin- and RANTES-mRNA but no MCP-3-mRNA in non-atopic and atopic nasal polyps when compared to normal nasal mucosa.
