Abstract： 目的: 研究Nogo-66受体(NgR)在成年大鼠脊髓白质的分布情况. 方法: 选用正常雄性SD大鼠脊髓切片,进行免疫组织化学、免疫荧光双标和包埋前免疫电镜染色,观察NgR免疫阳性物质在脊髓白质的定位情况. 结果: 在光镜水平可观察到NgR阳性的点状结构主要分布在脊髓白质胶质细胞胞体周边和突起上,且与细胞膜关系密切;在电镜水平可观察到NgR阳性的胶体金颗粒分布在星形胶质细胞之间,寡突胶质细胞之间以及星形胶质细胞和寡突胶质细胞之间的缝隙连接上. 结论: 本研究提供了NgR在正常成年大鼠脊髓白质胶质细胞分布并且在缝隙连接定位的形态学证据,提示NgR可能在胶质细胞间的通讯中发挥一定的调节功能.
