为探讨细胞骨架在肺抗原呈递细胞和其它细胞的表达 ,用细胞骨架的单克隆抗体对日本正常雌兔肺切片进行免疫组织化学 ABC法染色。结果表明 ,肌动蛋白 (actin)表达于血管、肺内导气部管壁的平滑肌 ;微管蛋白(tubulin)和角蛋白 - 7(cytokeration- 8)表达于 Clara细胞、肺泡 型和 型上皮细胞以及肺巨噬细胞 ;波形蛋白(vim entin)表达于肺血管内皮和肺巨噬细胞。本文对细胞骨架的意义进行了讨论 To investigate the expression of cytoskeleton in lung antigen-presenting cells and other cells, immunohistochemical ABC staining was performed on the lung sections of normal Japanese female rabbits by cytoskeleton monoclonal antibody. The results showed that actin was expressed in the smooth muscle of vessel wall and airway in the lung. Tubulin and cytokeration-8 were expressed in Clara cells, alveolar type and type epithelial cells And pulmonary macrophages; vim entins are expressed in pulmonary vascular endothelium and lung macrophages. This article discusses the implications of cytoskeleton
