摘要

Respiratory distress syndrome (RDS) was the eighth leading cause of death in infants during 2010 in the United States [National Center for Health Statistics, 2013]. Respiratory disease, including RDS, is the most common cause of morbidity and mortality in preterm infants. RDS occurs due to pulmonary surfactant deficiency and a lack of structural maturation of the lungs [Moss, 2006]. Pulmonary surfactant is produced by alveolar type II cells and stored in lamellar bodies. When released via exocytosis, pulmonary surfactant decreases surface tension by forming a lipid layer that allows for the proper inflation of the lungs [Shulenin et al., 2004]. Twin studies and surfactant-associated gene mutations strongly support a role for genetics, particularly in severe forms of RDS in term and near term infants [van Sonderen et al., 2002; Shulenin et al., 2004; Hallman et al., 2007; Levit et al., 2009; Wambach et al., 2010; Ryckman et al., 2012].
