Summary

在这里,我们提出了一个详细的方案来可视化神经肌肉接头和肌肉细胞中的微管网络。结合 黑腹果蝇强大的遗传工具,该方案极大地促进了微管网络调节蛋白在神经系统中的作用的遗传筛选和微管动力学分析。

Transcript

目前,微管动力学是通过微管结合蛋白(如EB1)间接观察到的。由于微管蛋白异二聚体在细胞质中含量丰富,直接折叠,相邻的微管蛋白异二聚体缺乏体内微管网络的动力学。我们的方案可视化了神经肌肉突触和肌肉细胞中的微管。

当与黑腹果蝇中可用的强大遗传工具相结合时,可以进行各种表型检查和遗传筛选,以发现微管网络调节蛋白在体内神经系统中的作用。我们的研究重点是细胞骨架与神经发育之间的关系,以及它对神经系统疾病的影响。我们希望通过强调细胞骨架调节蛋白对神经元的影响来发现神经发育和神经系统疾病孤雌生殖的机制。
