[Antimicrobial peptides and proteins in chronic rhinosinusitis].

Abstract

The pathogenesis of chronic rhinosinusitis（CRS） is closely related to the interactions between the environmental stimuli and the innate defense system. A vast of defensive molecules, such as antimicrobial peptides and proteins（AMPs） could be secreted by the airway epithelial cells and submucosal glands. As an essential component of innate immune system, AMPs are associated with multiple airway disease, such as CRS, chronic obstructive pulmonary disease, bronchiectasis, allergic asthma and so on. AMPs are expressed vastly in nasal mucosa and could exert fundamental antibacterial and inflamatory regulative functions. However, the pathophysiological mechanism of AMPs in CRS is still unclear. What s more, the heterogeneity among studies is relatively high. Thus, the paper was aimed to review the potential function and inflammatory regulation of AMPs in CRS. More rigorous studies with larger samples are needed in the future, to shed light on its possible pathogeneisis mechanisms.
