Gene expression differences in nitric oxide and reactive oxygen species regulation point to an altered innate immune response in chronic rhinosinusitis

Abstract

Alteration in gene expression points to impaired innate immune responses differing among CRS subgroups based on S. aureus biofilm and polyp status. The consistent alteration of 4 genes among distinct groups demonstrates that S. aureus biofilms and polyps are associated with specific changes in gene expression. Further studies are required to validate these findings in a wider cohort of patients and correlate this to protein expression and disease manifestation.
