肺表面活性物质是一种复杂的高表面活性物质。它覆盖肺泡上皮,由90%的脂质和10%的蛋白质组成。肺表面活性物质脂质与肺表面活性物质蛋白一起通过降低肺内空气-水界面的表面张力来促进呼吸,从而防止肺泡塌陷和呼吸所需的机械功。此外,肺表面活性物质脂质(如磷脂酰甘油和磷脂酰肌醇)和肺表面活性物质蛋白(如表面活性物质蛋白A和D)参与肺宿主防御并改变免疫应答。新出现的数据表明,肺表面活性物质脂质调节某些呼吸道病毒感染的炎症反应和抗病毒作用,并且肺表面活性物质脂质已显示出在某些呼吸道病毒感染中的治疗应用前景。本文就肺表面活性物质脂质的组成、抗病毒特性及其在呼吸道病毒感染中的潜在治疗应用作一综述。
Pulmonary surfactant is a complex and highly surface-active material. It covers the alveolar epithelium and consists of 90% lipids and 10% proteins. Pulmonary surfactant lipids together with pulmonary surfactant proteins facilitate breathing by reducing surface tension of the air-water interface within the lungs, thereby preventing alveolar collapse and the mechanical work required to breathe. Moreover, pulmonary surfactant lipids, such as phosphatidylglycerol and phosphatidylinositol, and pulmonary surfactant proteins, such as surfactant protein A and D, participate in the pulmonary host defense and modify immune responses. Emerging data have shown that pulmonary surfactant lipids modulate the inflammatory response and antiviral effects in some respiratory viral infections, and pulmonary surfactant lipids have shown promise for therapeutic applications in some respiratory viral infections. Here, we briefly review the composition, antiviral properties, and potential therapeutic applications of pulmonary surfactant lipids in respiratory viral infections.
