We used phalloidin staining and immunocytochemistry at the light and electron microscope level to determine the localization of actin in the cell bodies of rat spinal ganglion neurons. The results show that actin is mostly concentrated along the periphery of the neuronal perikaryon, including the perikaryal projections. This localization places actin in a strategic position to be influenced by incoming signals and to produce mechanical tensions able to shape the perikaryal surface.
我们在光学显微镜和电子显微镜水平上使用鬼笔环肽染色和免疫细胞化学方法来确定肌动蛋白在大鼠脊髓神经节神经元细胞体中的定位。结果表明，肌动蛋白主要集中在神经元胞体的周边，包括胞体突起。这种定位使肌动蛋白处于一个关键位置，能够受到传入信号的影响，并产生能够塑造胞体表面的机械张力。
