In cystic fibrosis (CF), impaired airway surface hydration (ASL) and mucociliary clearance that promote chronic bacterial colonization, persistent inflammation, and progressive structural damage to the airway wall architecture are typically explained by ion transport abnormalities related to the mutation of the gene coding for the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) channel. However, the progressive and unrelenting inflammation of the CF airway begins early in life, becomes persistent, and is excessive relative to the bacterial burden. Intrinsic abnormalities of the inflammatory response in cystic fibrosis have been suggested but the mechanisms involved remain poorly understood. This review aims to give an overview of the recent advances in the understanding of the defective resolution of inflammation in CF including the abnormal production of specialized pro-resolving lipid mediators (lipoxin and resolvin) and their impact on the pathogenesis of the CF airway disease.
在囊性纤维化 (CF) 中,气道表面水合作用 (ASL) 受损和黏液纤毛清除功能障碍导致慢性细菌定植、持续炎症和气道壁结构的进行性结构损伤,通常可以用与编码囊性纤维化跨膜电导调节因子 (CFTR) 通道的基因突变相关的离子转运异常来解释。然而,CF 气道的进行性和持续不断的炎症早在生命早期就开始了,持续存在且相对于细菌负担而言过度。已经提出了 CF 中炎症反应的内在异常,但相关机制仍知之甚少。本综述旨在概述对 CF 中炎症消退缺陷的理解的最新进展,包括专门的促解决脂质介质(脂氧素和 resolvin)的异常产生及其对 CF 气道疾病发病机制的影响。
