Respiratory epithelium - Wikipedia
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.
Cellular and functional heterogeneity of the airway epithelium …
In a healthy state (blue arrows), basal cells are the principal stem cells of the airway, facilitating epithelial regeneration. Club cells secrete the anti-inflammatory protein uteroglobin,...

2023年5月1日 · Respiratory epithelium is ciliated pseudostratified columnar epithelium found lining most of the respiratory tract; it is not present in the larynx or pharynx. The epithelium classifies as pseudostratified; though it is a single layer of cells along the basement membrane, the alignment of the nuclei is not in the same plane and appears as ...
Lung Cytopathology (Bronchial and Aspiration Cytology) - PMC
Sometimes, ciliated respiratory epithelial cells can be identified in the sputum, but they do not necessarily represent cells that come from the lower respiratory tract, since ciliated respiratory epithelial cells can be found in the lining of sinonasal passage of the upper respiratory tract.
Respiratory Epithelium - an overview | ScienceDirect Topics
Ciliated cells line the respiratory tract down to the level of the respiratory bronchiole. Tracheobronchial glands and goblet cells are important sources of airway mucus, which serves to nonspecifically trap particulates.
Regulation of immune responses by the airway epithelial cell ... - Nature
2021年1月13日 · A pseudotime analysis of nasal airway epithelial cells in air–liquid interface cultures demonstrated that goblet cells could act as precursors to ciliated cells and that transitory FOXJ1...
Respiratory epithelial cells orchestrate pulmonary innate immunity …
2014年12月18日 · Respiratory epithelial cells have an essential important role in the initial recognition and amplitude of the inflammatory responses to microbial pathogens through...
Respiratory epithelial cells orchestrate pulmonary innate immunity
The biophysical scaffolds created by the mucus gel, tight cell-cell junctions and communication among respiratory epithelial cells provide multiple barriers to infection. The secretion of fluid and mucus is coordinated with the directional beating of cilia (ultrastructure in electronmicrograph in b ) mediated by Cnx43.
Ciliated Epithelium - an overview | ScienceDirect Topics
This ciliated epithelium consists of a number of different cell types, including columnar ciliated cells, mucus-producing goblet cells, serous cells, Clara cells, brush cells, neuroendocrine cells, and basal cells. 5,6 Ciliated cells are in physical contact at tight junction desmosomes, and in physiologic communication via gap junctions. 7 ...
Airway ciliated cells in adult lung homeostasis and COPD
The pseudostratified respiratory epithelium (from the nasal cavity to the bronchi) is covered with mucus produced by secretory cells in order to trap inhaled particles, microorganisms and pathogens. The mucociliary clearance establishes a frontline lung defence mechanism: motile cilia remove the mucus via ciliary beating into the airway ...
