摘要

突触前末端α-突触核蛋白的分泌通过钙依赖机制受到神经元活性的控制。为了解决电压门控钙通道在这一过程中的作用，我们使用反向脑微透析来监测α-突触核蛋白在选择性通道抑制剂存在下的体内释放。结果表明，ω- concontoxin对gvia敏感的n型钙通道是刺激小鼠纹状体α-突触核蛋白分泌的主要介质。

N-type Ca2+ channels mediate the stimuli-dependent α-synuclein secretion in mouse striatum.

The secretion of α-synuclein from presynaptic terminals is controlled by neuronal activity through a calcium-dependent mechanism. To address the role of voltage gated calcium channels in this process, we used reverse brain microdialysis to monitor α-synuclein release in vivo in the presence of selective channel inhibitors. Our results revealed that the ω-conotoxin GVIA-sensitive N-type calcium channels are the major mediators of stimulated α-synuclein secretion in mouse striatum.
