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. Basal cells have a local progenitor function, possessing the ability to differentiate … 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 …

WebChronic lung diseases present tremendous health burdens and share a common pathobiology of dysfunctional epithelial repair. Lung adenocarcinoma, the leading cancer killer worldwide, is caused mainly by chemical carcinogens of tobacco smoke that induce mutations in pulmonary epithelial cells leading to uncontrolled epithelial proliferation. … WebAbstract: BACKGROUND: Pulmonary fibrosis (PF) is one of the main causes of death in patients with paraquat (PQ) poisoning. This study aimed to evaluate the relationship between mitochondrial fission and oxidative stress in PQ-induced epithelial-mesenchymal transition (EMT) and PF. WebAug 15, 2024 · Like most cells in your body, the lung neuroendocrine cells sometimes go through certain changes that cause them to grow too much and form tumors. These are known as neuroendocrine tumors or neuroendocrine cancers. (Neuroendocrine cells in other parts of the body can also form tumors and cancers.)
