Increased eotaxin-mRNA expression in non-atopic and atopic nasal polyps: comparison to RANTES and MCP-3 expression

J Bartels et al. Rhinology. 1997 Dec.

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.
