13-羟基十八碳二烯酸(13-HODE)是氧化型低密度脂蛋白(OxLDL)的主要成分,在动脉粥样硬化形成中起重要作用。在13-HODE立体异构体13(S)-HODE和13(R)-HODE中,与前者相比,对后者知之甚少。为了检测动脉粥样硬化病变中的13(R)-HODE,我们制备了抗13(R)-HODE的小鼠单克隆抗体。竞争性酶联免疫吸附试验阐明了克隆mAb 13 H1与游离和牛血清白蛋白偶联形式的13(R)-HODE的选择性反应,但不与其他氧化脂质(包括13(S)-HODE)反应。免疫组织化学分析显示13(R)-HODE免疫反应性与OxLDL标记氧化磷脂酰胆碱免疫反应性在人颈动脉粥样硬化斑块中的血管内皮细胞、巨噬细胞和迁移的血管平滑肌细胞中共定位。本研究结果为颈动脉粥样硬化病变中13(R)-HODE的形成提供了体内证据。
13-Hydroxyoctadecadienoic acid (13-HODE) is a major component of oxidized low density lipoprotein (OxLDL), which has been shown to have a crucial role in atherogenesis. Of the 13-HODE stereoisomers, 13(S)-HODE and 13(R)-HODE, little is known about the latter in contrast to the former. To detect 13(R)-HODE in atherosclerotic lesions, we prepared a mouse monoclonal antibody against 13(R)-HODE. Competitive enzyme-linked immunosorbent assay clarified the selective reaction of a clone mAb 13H1 with both free and bovine serum albumin-conjugated forms of 13(R)-HODE but not other oxidized lipids including 13(S)-HODE. Immunohistochemical analysis revealed the colocalization of 13(R)-HODE immunoreactivity with the OxLDL marker oxidized phophatidylcholine immunoreactivity in vascular endothelial cells, macrophages and migrating vascular smooth muscle cells in atherosclerotic plaques of human carotid arteries. The present results provide in vivo evidence for the formation of 13(R)-HODE in atherosclerotic lesions of carotid arteries.
