Stroke:实验性脑出血对神经元CD163表达的影响!

2017-03-31 xing.T MedSci原创

CD163在神经元中表达并在ICH后表达上调。去铁胺可以降低在体ICH诱导的CD163上调和脑细胞死亡,以及离体血红蛋白诱导的CD163表达上调和神经元死亡。

CD163,是血红蛋白的受体,参与了脑出血(ICH)后血红蛋白的清除。与小胶质细胞/巨噬细胞CD163不同,神经元CD163血红蛋白还没有被充分的研究。近日,卒中领域权威杂志Stroke上发表了一篇研究文章,该研究旨在ICH猪模型和体外培养的大鼠皮层神经元上探讨神经元CD163的表达,以及去铁胺对神经元CD163表达的影响。

该研究分为2部分。在体部分,在小猪右额叶注射自体血液。研究人员在灰质中确定ICH后CD163表达的时间效应以及去铁胺对CD163表达的影响。在体外,研究人员采用血红蛋白处理培养的大鼠皮层神经元来评估CD163表达水平、神经元死亡和去铁胺的效应。

研究人员发现了CD163阳性细胞,并且在ICH后同侧灰质内CD163蛋白水平上调。CD163水平在1天和3天达到高峰。CD163阳性细胞共定位于NeuN阳性、血红素氧合酶-2阳性和末端脱氧核苷酰转移酶dUTP缺口末端标记阳性的细胞。去铁胺治疗可以减少ICH引起的CD163上调和显著降低3天大脑CD163和血红蛋白水平。用血红蛋白处理神经细胞24个小时可以导致CD163表达上调和细胞死亡增加。去铁胺可以显著降低血红蛋白诱导的神经元死亡和CD163的表达上调。

CD163在神经元中表达并在ICH后表达上调。去铁胺可以降低在体ICH诱导的CD163上调和脑细胞死亡,以及离体血红蛋白诱导的CD163表达上调和神经元死亡。
