Methods for studying mucociliary transport.
UNLABELLED Mucociliary transport dysfunctions can impair the quality of life of patients suffering from chronic rhinossinusitis and lead to severe consequences such as alterations in respiratory physiology or even death as in cases of cystic fibrosis and primary ciliary dyskinesia. Therefore, it is crucial to understand the physiology of the mucociliary apparatus and how its components (cilia, ...
متن کاملAssessment of pulmonary mucociliary transport using magnetic nanoparticles: influence of their surface potential
Objective(s): Inhaled aerocontaminants are removed from the lungs by pulmonary mucociliary transport (MCT) as an important defense mechanism. This study was undertaken to investigate the influence of the surface potential of magnetic nanoparticles (MNPs) on the MCT in murine lungs by use of magnetic particle imaging (MPI).Materials and Methods: Three kinds of MNPs (carboxymethyl dextran m...
متن کاملContinuous mucociliary transport by primary human airway epithelial cells in vitro.
Mucociliary clearance (MCC) is an important innate defense mechanism that continuously removes inhaled pathogens and particulates from the airways. Normal MCC is essential for maintaining a healthy respiratory system, and impaired MCC is a feature of many airway diseases, including both genetic (cystic fibrosis, primary ciliary dyskinesia) and acquired (chronic obstructive pulmonary disease, br...
متن کاملEffects of nitric oxide in mucociliary transport.
UNLABELLED The airways are made up of ciliated epithelium which secretes mucous, protecting the respiratory tract from particles inhaled during breathing. Its is paramount to understand the physiology and the mechanisms involved in mucociliary activity. Literature suggests that Nitric oxide (NO), especially the one produced by iNOS expression, maintains the mucociliary function and the immune d...
متن کاملLiquid secretion inhibitors reduce mucociliary transport in glandular airways.
Because of its possible importance in cystic fibrosis (CF) pulmonary pathogenesis, the effect of anion and liquid secretion inhibitors on airway mucociliary transport was examined. When excised porcine tracheas were treated with ACh to induce gland liquid secretion, the rate of mucociliary transport was increased nearly threefold from 2.5 +/- 0.5 to 6.8 +/- 0.8 mm/min. Pretreatment with both bu...
