凝血酶对蛋白C的激活作用被内皮细胞辅因子血栓调节蛋白显著加速。在这项研究中,我们已经建立了一个血栓调节蛋白的放射免疫测定法,并测定了几种人体组织中的辅因子含量。该测定方法可检测到低至2 ng的血栓调节蛋白。肺和胎盘中血栓调节蛋白含量最高,但脾、胰腺、肝、肾、皮肤、心脏和主动脉中也检测到抗原。出乎意料的是,血栓调节蛋白在脑中不存在。大脑皮质、小脑、半卵圆中心、中脑、基底节、脑桥和髓质的提取物不含血栓调节蛋白。相反,血栓调节蛋白抗原存在于脑外颅内血管,包括基底动脉和颈内动脉和脉络丛,以及软脑膜-蛛网膜的内皮中。
Protein C activation by thrombin is significantly accelerated by the endothelial cell cofactor, thrombomodulin. In this study, we have developed a radioimmunoassay for thrombomodulin and have measured the cofactor content in several human tissues. The assay method detects as little as 2 ng of thrombomodulin. The highest thrombomodulin content was found in lung and placenta, but the antigen was also detected in spleen, pancreas, liver, kidney, skin, heart, and aorta. Unexpectedly, thrombomodulin was absent from brain. Extracts from cerebral cortex, cerebellum, centrum semiovale, midbrain, basal ganglia, pons, and medulla were devoid of thrombomodulin. In contrast, thrombomodulin antigen is present in extracerebral intracranial vessels, including basilar and internal carotid arteries and choroid plexus, as well as in endothelium of the pia-arachnoid.
