Tau蛋白又称微管相关蛋白 ,是一种神经元功能蛋白 ,能促使微管蛋白连接起来形成微管。从形态学方面研究神经细胞在衰老过程中 Tau蛋白的变化国内外尚未见报道。本实验选用 1月、10月及 2 0月龄的 Wistar大鼠各 10只 ,乙醚麻醉下 ,取大脑皮质 ,10 %甲醛固定 ,常规石蜡包埋 ,切片 Tau protein, also known as microtubule-associated protein, is a neuronal functional protein that causes tubulin to join to form microtubules. From the morphological aspects of neural cells in the aging process of Tau protein changes have not been reported at home and abroad. In this experiment, 10 Wistar rats were selected from January, October and 20 months. Under anesthesia with ether, the cerebral cortex was taken, fixed with 10% formaldehyde, embedded in paraffin and sectioned
