Single cell transcriptomic analysis reveals transcriptome differences of different cells between eosinophilic chronic rhinosinusitis with nasal polyps and non-eosinophilic chronic rhinosinusitis with nasal polyps.

ABSTRACT:

Background

Chronic rhinosinusitis (CRS) with nasal polyps is a heterogeneous chronic inflammatory disease generally divided into two phenotypes including eosinophilic CRS with nasal polyps (eCRSwNP) and non-eosinophilic CRS with nasal polyps (neCRSwNP). However, its pathogenesis remains largely unknown. The aim of this study was to explore mechanistic differences between eCRSwNP and neCRSwNP using a bioinformatics approach.

Methods

We comprehensively analyzed single-cell RNA sequencing data from 3 healthy controls and 6 patients with CRSwNP (including 3 with eCRSwNP and 3 with neCRSwNP) to explore the heterogeneity and potential mechanisms of CRSwNP.

Results

Cluster analysis based on differential gene expression delineated 14 cell clusters. The eCRSwNP group exhibited
