Study Details

Study Description

Brief Summary

Epigenetic modifiers has been showed to rescue F508del-CFTR channel to apical membrane of epithelial cell lines. In this study, the investigators evaluate epigenetic modifiers effects firstly on CFTR rescue, then on secretion and synthesis of inflammatory factors (IL-8, LXA4 and SCGB1A1) and mucines (MUC5AC and MUC5B) in a dynamic epithelium model using an air-liquide interface culture of nasals cells from CF patients or controls.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Cystic Fibrosis patients (CF)

Tests in vitro after sampling nasal cells of CF patients or controls are the intervention done on these subjects

Other: Tests in vitro after sampling nasal cells of CF patients or controls
Nasal cells of CF patients or controls were collected by scratching of intermediate turbinate and cultured in vitro. Epigenetic modifiers treatment was applied to these ex vivo nasal epithelia. Then, mRNA, protein and secretions were quantified.

Other: Control subjects (non CF)

Tests in vitro after sampling nasal cells of CF patients or controls are the intervention done on these subjects

Other: Tests in vitro after sampling nasal cells of CF patients or controls
Nasal cells of CF patients or controls were collected by scratching of intermediate turbinate and cultured in vitro. Epigenetic modifiers treatment was applied to these ex vivo nasal epithelia. Then, mRNA, protein and secretions were quantified.

Outcome Measures

Primary Outcome Measures

  1. Mature CFTR protein percentage variation after in vitro epigenetics modifiers treatment [24 months]

Secondary Outcome Measures

  1. Pro-inflammatory cytokines number variations after epigenetic modifiers treatment [24 months]

  2. Anti-inflammatory cytokines number variations after epigenetic modifiers treatment [24 months]
