背景情况:

囊性纤维化 (CF) 呼吸道疾病在使用Elexacaftor/tezacaftor/ivacaftor (ETI) CFTR调制剂治疗时显著改善.
长期的分子和细胞机制,疗效以及ETI的气道重塑逆转仍然不清楚.

研究的目的:

在两年内调查CF气道疾病中ETI治疗的分子和细胞机制.
为了评估基因表达,细胞组成,干细胞功能和ETI治疗后的微生物组变化.

主要方法:

从成年CF患者的长度鼻刷样本在基线,在ETI启动6个月和2年后被分析.
评估了基因表达,细胞组成,气道上皮干细胞分化,屏障能力和微生物群.

主要成果:

在6个月内,ETI治疗导致了显著的中性恋炎症降低和改善肺功能.
空气道上皮干细胞显示部分改善了分化和屏障能力.
虽然临床结果保持稳定,但转录分析显示,在6个月至2年之间,炎症基因表达的复苏.

Cystic Fibrosis: Management

Cystic Fibrosis: Management

Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Cystic Fibrosis: Pathogenesis

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
