Low Dose Cadmium Exposure Induces Peribronchiolar Fibrosis through Site Specific Phosphorylation of Vimentin

Exposure to cadmium (Cd) has been associated with development of chronic obstructive lung disease (COPD). The mechanisms and signaling pathways whereby Cd causes pathological peribronchiolar fibrosis, airway remodeling and subsequent airflow obstruction remain unclear. We aimed to evaluate whether low dose Cd exposure induces vimentin phosphorylation and YAP1 activation leading to peribronchiolar fibrosis and subsequent airway remodeling.

Intrapulmonary Instillation of Perflurooctylbromide Improves Lung Growth, Alveolarization, and Lung Mechanics in a Fetal Rabbit Model of Diaphragmatic Hernia

 Fetal tracheal occlusion of hypoplastic rabbit lungs results in lung growth and alveolarization although the surfactant protein messenger RNA expression is decreased and the transforming growth factor-β pathway induced. The prenatal filling of healthy rabbit lungs with perfluorooctylbromide augments lung growth without suppression of surfactant protein synthesis.
