Proteomic analysis of mucus from chronic rhinosinusitis patients with or without nasal polyps


ABSTRACT: Patients with chronic rhinosinusitis (CRS) have abnormal immune responses triggered by a variety of infectious agents, airborne toxins and fungi. Respiratory epithelial cells serve as relay stations capable of amplifying or augmenting cues received from external stimuli to nearby immune cells located in the sinus mucosa. Previous studies have identified increases in complement components and complement gene expression in the mucosa of patients with atopic CRS with nasal polyps (CRSwNP). As part of a larger study, we used shotgun proteomics to quantify changes in mucus proteins between patients with and without nasal polyps.

In patients with chronic rhinosinusitis with nasal polyps, primary human sinonasal epithelial cell (HSNEC) 1α-hydroxylase levels are reduced, as is their ability to metabolize 25-hydroxycholecalciferol [25(OH)D<sub>3</sub>] to its active metabolite, 1α,25-dihydroxyvitamin D<sub>3</sub> [1,25(OH)<sub>2</sub>D<sub>3</sub>]. In this study, we sought to identify the factor responsible for the regulation of HSNEC metabolism of 25(OH)D<sub>3</sub>, focusing on C3 and C3a. Multiple inhaled irritants tr  ...[more]
