摘要：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Ⅰ型和Ⅱ型上皮细胞以及肺巨噬细胞；波形蛋白(vimentin)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。

Abstract：To investigate the distribution of cytoskeletal components in rabbit, the lung of normal female adult white rabbits were fixed well in 4% 40 paraformaldehyde and paraffin section were prepared accoridng to routine methods. Anticytokeratin-7, -8, -18, -19, antiactin, antivimentin and anti-alpha-tubulin monochlonae antibodies, were employed with immunohistochemical ABC methed. Resalts: The clara ceils in terminal and respiratory bronchioles were immunopositive for cytokeratin-7, vimentin and alpha-tubulin. The type Ⅰ and type Ⅱ pulmonary alveolar cells show positive reactivity for cytokeratin-7 and alpha-tubulin. The alveolar macrophage shows cytokeratin-7, vimentinand alpha-tubulin positive. The smooth muscle cells in small bronchus, terminal and respiratory bronchioles and alveolar duct show actin positive. Significance of expression of these cytoskeletal proteins in lung was discussed.
