Pulmonary surfactant is a surface active material composed of both lipids and proteins that is produced by alveolar type II pneumocytes. Abnormalities of surfactant in the immature lung or in the acutely inflamed mature lung are well described. However, in a variety of subacute diseases of the mature lung, abnormalities of lung surfactant may also be of importance. These diseases include chronic obstructive pulmonary disease, asthma, cystic fibrosis, interstitial lung disease, pneumonia, and alveolar proteinosis. Understanding of the mechanisms that disturb the lung surfactant system may lead to novel rational therapies for these diseases.
肺表面活性物质是一种由脂质和蛋白质组成的表面活性物质,由II型肺泡上皮细胞产生。未成熟肺或急性炎症成熟肺中表面活性物质的异常已有充分描述。然而,在成熟肺的各种亚急性疾病中,肺表面活性物质异常也可能很重要。这些疾病包括慢性阻塞性肺疾病、哮喘、囊性纤维化、间质性肺疾病、肺炎和肺泡蛋白沉积症。了解干扰肺表面活性物质系统的机制可能会为这些疾病带来新的合理治疗方法。
