Expression of ecalectin, a novel eosinophil chemoattractant, in nasal polyps

Abstract

The number of EG2- and ecalectin-positive cells was significantly higher in nasal polyps than control turbinates. Ecalectin-positive cells were observed in the subepithelial layer, where many EG2-positive cells were present. The number of ecalectin-positive cells correlated significantly with the number of EG2-positive cells in nasal polyps. Many ecalectin mRNA-positive cells were also observed in nasal polyps with an accumulation of EG2-positive cells.
