表面活性剂蛋白a (SP-A)是肺表面活性剂系统中最重要的一种蛋白。SP-A在II型肺泡上皮细胞以及部分非小细胞肺癌(NSCLC)中表达。SP-A的表达在转录和染色体水平上受到复杂的调控。SP-A是肺细胞因子网络的主要参与者,并且已被描述为在肺宿主防御中起作用。通过细胞培养或动物模型的使用,SP-A的功能特性在许多方面都得到了反复的展示,通常具有令人惊讶的特性,这些特性强烈地表明SP-A的生理重要性。迄今为止,SP-A被认为是肺发育、结构和功能所必需的分子。即将发表的一些报告涉及SP-A在肺部病理中的作用。本文综述了SP-A在人类肺部疾病中的应用,并指出了以病理为导向的研究方法的重要性,利用免疫组织化学或原位杂交作为有前途的方法,进一步阐明该分子在成人肺部疾病中的作用。
Surfactant Protein-A (SP-A) is the most prominent among four proteins in the pulmonary surfactant-system. SP-A is expressed by alveolar epithelial cells type II as well as by a portion of non small cell lung carcinomas (NSCLC). The expression of SP-A is complexly regulated on the transcriptional and the chromosomal level. SP-A is a major player in the pulmonary cytokine-network and moreover has been described to act in the pulmonary host defense. By the use of cell culture or animal models the functional properties have been repeatedly shown in many aspects, often bearing surprising properties which strongly indicate the physiological importance of SP-A. To date SP-A is recognized as a molecule essential for pulmonary development, structure and function. An upcoming number of reports deals with the role of SP-A for pulmonary pathology. This article gives an overview about the state of knowledge on SP-A focused in applications for human pulmonary disorders and points out the importance for pathology-orientated research approaches using immunohistochemistry or in situ hybridization as promising methods to further elucidate the role of this molecule in adult lung diseases.
