WebAlveolar epithelial cell senescence, cell cycle arrest, and the SASP may contribute to the development and perpetuation of fibrotic scarring. In a mouse model of bleomycin-induced pulmonary fibrosis, alveolar epithelial cells exhibited increased expression of senescence-associated markers, including β-galactosidase activity, p16, p21, pRb (47,48). WebAbstract. Idiopathic pulmonary fibrosis (IPF) is characterised by repeated injury to the alveolar epithelium with loss of lung epithelial cells and abnormal tissue repair, resulting in excessive accumulation of fibroblasts and myofibroblasts, deposition of extracellular matrix components and distortion of lung architecture, eventually leading to respiratory failure.

WebAug 1, 2024 · One new cell type, which they named pulmonary ionocytes, was particularly striking as these cells expressed higher levels of CFTR than any other cell. A live-imaging technique captures cilia beating and the transport of debris across the surface of the epithelium. Pulmonary ionocytes appear to play a role in this process, which is necessary … WebOct 15, 2024 · Pulmonary epithelial cells are widely considered to be the first line of defence in the lung and are responsible for coordinating the innate immune response to injury and subsequent repair. Consequently, epithelial cells communicate with multiple cell types including immune cells and fibroblasts to promote acute inflammation and normal wound …

WebMay 19, 2024 · Figure 1 The normal lung epithelium composition changes along the respiratory tree from proximal airways to alveolar areas. Secretory cells produce the mucus lining the airways, which is moved upstream by the ciliated beats originating from ciliated cells.
