Club cells are infrequently found in the human upper airway.
The respiratory epithelium functions to moisten and protect the airways. It acts as a physical barrier to pathogens, as well as their removal in the mechanism of mucociliary clearance. The ciliated cells are the primary components in the mucociliary clearance mechanism. Each epithelial cell has around 200 cilia that beat constantly at a rate of between 10 and 20 times per second. The direction of their beat is targeted towards the pharynx, either upwards from the low… WebJul 23, 2009 · We studied several T2Rs for which antibodies are available and/or for which ligands are known, and we identified T2R4, T2R43, T2R38, and T2R46 in human airway epithelia (Fig. 2, A to C, and figs.
