Surfactant and its Role

Pulmonary surfactant: its isolation, characterization and function.

The role of surfactant in asthma

Pulmonary surfactant is a unique mixture of lipids and surfactant-specific proteins that covers the entire alveolar surface of the lungs. Surfactant is not restricted to the alveolar compartment; it also reaches terminal conducting airways and is present in upper airway secretions. While the role of surfactant in the alveolar compartment has been intensively elucidated both in health and diseas...

Pulmonary surfactant and inflammation in septic adult mice: role of surfactant protein A.

Surfactant alterations, alveolar cytokine changes, and the role of surfactant protein (SP)-A in septic mice were investigated. Sepsis was induced via cecal ligation and perforation (CLP). Septic and sham mice were euthanized at 0, 3, 6, 9, 12, 15, and 18 h after surgery. Mice deficient in SP-A and mice that overexpressed SP-A were euthanized 18 h after surgery. In wild-type, sham-operated mice,...

Neonatal Respiratory Distress Syndrome and Its Treatment with Artificial Surfactant

Neonatal respiratory distress syndrome [4], previously called hyaline membrane disease, is a respiratory disease affecting premature newborns. Neonatal respiratory distress syndrome [4] involves shallow breathing, pauses between breaths that last a few seconds, or apnea, and a bluish tinge to the infant?s skin. The syndrome occurs when microscopic sacs called alveoli in infant lungs do not prod...
