Mechanisms of atelectasis. A, Collapse of the lung in pneumothorax. B, Compression of the lung by pleural fluid. C, Resorption of the air from alveoli distal to an obstructed bronchus. Obstructive atelectasis is usually focal. Atelectasis of premature infants, which is caused by a deficiency of pulmonary surfactant, is not shown

Phosphatidylglycerol is a glycerophospholipid found in pulmonary surfactant. It is the precursor of surfactant and its presence (>0.3) in the amniotic fluid of the newborn indicates fetal lung maturity.

There are around 150 million alveoli in a human lung. 95% of the alveolar surface area is made of squamous (type I) alveolar cells which allow for gas diffusion between air and blood and 5% of great (type II) alveolar cells which are cuboidal shaped and repair the alveolar epithelium and secrete pulmonary surfactant. Pulmonary surfactant coats the alveoli &small bronchioles and prevents collapsing.

October 2012 - The EMBO Journal     Giant proteo-liposomes of pulmonary surfactant, material that lines the alveoli of mammals and allows breathing. Each vesicle is 20-50µm in diameter and contains fluorescent dyes highlighting the preferred localization and packing properties of the surfactant lipids and proteins in the membrane.

Discovery Laboratories, Inc., a specialty biotechnology company, focuses on developing products for critical-care patients with respiratory disease and improving care in pulmonary medicine. Its proprietary drug technology produces a synthetic peptide-containing surfactant (KL4 surfactant in liquid, lyophilized, and aerosolized dosage forms)

Image of the Week: Microscopic view of lung surfactant This microscopic image of lung surfactant, a lipid-protein material that reduces surface tension in the lung and aids in proper pulmonary function, could easily be mistaken for a whimsical textile print. A recent issue of Biomedical Beat provides more information about the fanciful designs represented in the image and how they may offer insights into developing new methods for drug delivery:
