Differential expression of Toll-like receptor pathway genes in chronic rhinosinusitis with or without nasal polyps

Abstract

TLR2, TLR4, TLR7, and IL-4 were significantly increased in CRSwNP patients when compared with either CRSsNP patients or control subjects, whereas TLR4 and TLR7, and downstream MyD88 were significantly decreased in CRSsNP patients versus patients from CRSwNP and control subjects.
