Neurology:突发性癫痫猝死的发病机制探讨

2017-01-15 xing.T MedSci原创

本研究是通过免疫组化的方法来探究SUDEP患者脑组织中潜在机制的一个起点。研究者的方法强调了采用免疫组化分析来帮助确定SUDEP的生物标志物的重要性。这项研究的结果表明,研究中所选择的标记物不是SUDEP患者脑组织中明确的免疫组化标记。

近日,神经病学领域权威取杂志Neurology上发表了一篇研究文章,研究人员以突发性癫痫猝死 (SUDEP)死亡患者队列为基础通过免疫组化技术检测了由于缺氧和血脑屏障(BBB)的破坏导致的炎症、增生和急性神经元损伤的特异性标志物旨在寻求SUDEP的一个神经病理学标记,从而提出与SUDEP死亡潜在机制的假说。

研究人员采用免疫组化的方法研究了58例死亡患者6种标记物(包括CD163、人类白细胞D抗原相关的抗原、胶质纤维酸性蛋白、缺氧诱导因子α[HIF-1α]、免疫球蛋白G和白蛋白)在海马、杏仁核和延髓的表达情况,其中包括28例SUDEP死亡患者(死后确诊的和很大可能的),12例癫痫死亡对照者,和18例非癫痫猝死的对照者。研究人员对所有的标记物的免疫反应进行半定量测量评分,并对选择的指标进行图像定量分析。

研究人员发现所有研究的脑区和组别中所有标记物均可以观察到他们的免疫反应性。炎症反应、血脑屏障渗漏和HIF-1α的免疫反应性在SUDEP病例中与对照组中相比不存在差异。

本研究是通过免疫组化的方法来探究SUDEP患者脑组织中潜在机制的一个起点。研究者的方法强调了采用免疫组化分析来帮助确定SUDEP的生物标志物的重要性。这项研究的结果表明,研究中所选择的标记物不是SUDEP患者脑组织中明确的免疫组化标记。
