| Zusammenfassung: | Copyright © 2018 Elsevier Inc. All rights reserved. B-cell activating factor (BAFF) has been proposed to play a crucial role in the pathogenesis of chronic rhinosinusitis with nasal polyp (CRSwNP). The aim of this study was to evaluate the role of toll-like receptor (TLR) 9-mediated BAFF activation on the pathogenesis of CRSwNP. NP and uncinate tissue (UT) were obtained from patients with CRSwNP or CRS without NP, and control subjects. The expression of TLR9, high mobility group box-1 protein (HMGB1), type I interferon (IFN), BAFF, and anti-double stranded DNA (dsDNA) antibody were examined in the tissues and the cultured dispersed NP cells (DNPCs). The expression of TLR9, HMGB1, type I IFN, BAFF, and anti-dsDNA antibody were elevated in NP tissue compared to the UTs. Exposure to TLR9 agonist increased the type I IFN expression in vitro, which further increased BAFF production. In conclusion, we provided a novel therapeutic potential of TLR9 agonist in CRSwNP |
