Cystic Fibrosis: Pathogenesis

358
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,...

Cystic Fibrosis: Management

222
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.
Sinus disease and chronic...

GPCRs Regulate Adenylyl Cylase Activity01:09

GPCRs Regulate Adenylyl Cylase Activity

5.9K
Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of...

科学领域:

  • 细胞生物学
  • 表皮生理学
  • 药理学

背景情况:

  • 囊性纤维化 (CF) 是由CFTR基因突变引起的遗传性疾病,影响多个器官.
  • CFTR调节剂在呼吸道上皮质中有效,但它们对胰腺CF上皮质的影响不太清楚.

研究的目的:

  • 研究CFTR调节剂 (ivacaftor,tezacaftor,elexacaftor) 在囊性纤维化中恢复胰腺管上皮的功效.
  • 在由脂聚糖 (LPS) 诱导的促炎条件下评估调节效应.

主要方法:

  • 用单个或组合的CFTR调节剂培养和治疗CFPAC-1细胞 (F508delCFTR突变).
  • 评估的功能参数包括体电导率,液体再吸收,峰值pH值,蛋白质度和微度.
  • 用LPS预先条件化细胞以模拟炎症.

主要成果:

  • Tezacaftor和elexacaftor,特别是在三重组合中,显著改善了上皮功能.
  • LPS增加了促炎细胞因子 (IL6,IL-8,IL-1β) 和顶部液体蛋白质含量.
  • 尽管LPS刺激,CFTR调节剂维持或增强了离子/流体运输恢复,但没有降低细胞因子水平.

结论:

  • 在试验室中,CFTR调节剂可以恢复囊性纤维化胰腺上皮的关键生理功能.
  • 在促炎性压力下,调节器的疗效仍然存在,这表明除了肺部疾病之外还有治疗潜力.
