In acquired pulmonary alveolar proteinosis, lipids and proteins accumulate within the alveoli
because alveolar macrophages cannot catabolize surfactants. Surprisingly, alveolar …

Pulmonary surfactant is an essential lipid–protein complex to maintain an operative
respiratory surface at the mammalian lungs. It reduces surface tension at the alveolar air …

Pulmonary surfactant is a critical component of lung function in healthy individuals. It
functions in part by lowering surface tension in the alveoli, thereby allowing for breathing …

The alveolar region of the lung creates an extensive epithelial surface that mediates the
transfer of oxygen and carbon dioxide required for respiration after birth. Maintenance of …

Recent evidence suggests that dysfunctional type II alveolar epithelial cells (AECs)
contribute to the pathogenesis of idiopathic pulmonary fibrosis (IPF). Based on the …
