Pulmonary surfactant is a complex surface-active substance comprised of key phospholipids and proteins that has many essential functions. Surfactant's unique composition is integrally related to its surface-active properties, its critical role in host defense, and emerging immunomodulatory activities ascribed to surfactant lipids. Together these effector functions provide for lung stability and protection from a barrage of potentially virulent infectious pathogens.
肺表面活性剂是一种复杂的表面活性物质,由关键的磷脂和蛋白质组成,具有许多重要的功能。表面活性剂的独特组成与其表面活性特性、在宿主防御中的关键作用以及归因于表面活性剂脂质的新兴免疫调节活性密切相关。这些效应功能共同为肺部提供稳定性,并防止一系列潜在的致命性传染性病原体的侵害。
