纹状体中星形胶质细胞内 Ca2+ 信号的性质和功能仍未完全探索。我们描述了使用血清型 2/5 (AAV2/5) 的腺相关病毒在纹状体星形胶质细胞中表达遗传编码的钙指示剂的方法,以及在纹状体星形胶质细胞内对 Ca2 + 信号进行原位成像的程序。

该程序的总体目标是使用遗传编码的钙指示剂(如细胞 G CAMP 三)对成年小鼠的 stri AAL 星形胶质细胞中的细胞内钙信号进行成像。这是通过首先将病毒注射到小鼠纹状体中来实现的。然后让小鼠在手术后恢复两到三周。

接下来,处死小鼠并制备急性脑切片。最后一步是进行脑切片的共聚焦钙成像。最终,免疫组织化学用于表明 Cyto G Camp 3 仅在星形胶质细胞中表达,而不在神经元中表达,并且病毒注射没有引起明显的星形胶质细胞反应性。
