约翰·霍普金斯医学研究人员发现轴是脑细胞的手臂结构, 不像以前想象的那样是圆柱形的, 而是类似于绳子上的珍珠。 Johns Hopkins Medicine researchers have found that axons, the arm-like structures of brain cells, are not cylindrical as previously thought, but resemble pearls on a string. 通过使用先进的显微镜, 他们观察到轴突沿线的"珍珠状"胀. Using advanced microscopy, they observed "pearl-like" swellings along the axons. 这种对xon结构的新理解可导致更好地了解脑细胞信号,并有可能为神经退化性疾病的治疗提供信息。 This new understanding of axon structure could lead to better insights into brain cell signaling and potentially inform treatments for neurodegenerative diseases.
