WebUncontrolled proliferation of stromal cells leads to pulmonary fibrosis just as uncontrolled growth of the respiratory epithelium produces pulmonary adenocarcinoma. Chronic inflammation, whether through inhaled particles, infection, or immune responses, may therefore establish ongoing inflammatory and proliferative cascades that lead to fibrosis … 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).

"WebLung epithelial cells (LECs) are strategically positioned in the airway mucosa to provide barrier defense. LECs also express pattern recognition receptors and a myriad of immune genes, but their role in immunity is often concealed by the activities of ‘‘professional’’ immune cells, particularly in the context of fungal infection.

WebTitle. Cigarette smoke alters the secretome of lung epithelial cells. Description. Cigarette smoke is the most relevant risk factor for the development of lung cancer and chronic obstructive pulmonary disease. Many of its more than 4500 chemicals are highly reactive, thereby altering protein structure and function. 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.
