Expression of eicosanoid receptors subtypes and eosinophilic inflammation: implication on chronic rhinosinusitis.

ABSTRACT:

Background

Eicosanoid receptors are G-protein-coupled receptors playing an important immunomodulatory role in airway diseases. However, there is little information on the expression of these receptors and their link with eosinophilic inflammation in paranasal sinus diseases. We aimed with this study to investigate the tissue expression of leukotrienes and prostaglandin E2 receptors in chronic rhinosinusitis patients and the link of this regulation with eosinophilic inflammation.

Methods

Samples were prepared from nasal tissue of patients with chronic rhinosinusitis without nasal polyps (CRS, n = 11), with nasal polyps (CRS-NP, n = 13) and healthy subjects (Controls, n = 6). mRNA expression of CysLT1, CysLT2, BLT1, BLT2, E-prostanoid receptors (EP1, EP2, EP3, EP4) and sol-IL-
