长期目标是研究钾离子通道调节对神经元信号的影响。具体目的是了解树突状电压门控钾通道和G蛋白是如何激活的海马神经元中的内向整流钾(GIRK)通道是如何调节的这些钾通道有助于神经元信号传递和突触可塑性。研究设计包括检查钾通道调节蛋白改变或缺失的突变小鼠，以调节树枝晶中通道的局部合成或调节通道的活性或动力学性质在细胞膜上的通道。因为KV1电压门控钾通道位于两个树突上和轴突，将采用双标记镶嵌分析(MADM)方法来研究树突状KV1通道的生理作用。

英文摘要

The long-term objectives are to study how potasslunn channels regulation contributes to neuronal signaling. The specific aims are to understand how the dendritic voltage-gated potassium channels and G proteinactivated inwardly rectifying potassium (GIRK) channels are regulated in hippocampal neurons, and how these potassium channels contribute to neuronal signaling and synaptic plasticity. The research design involves examination of mutant mice with altered or deleted potassium channel regulatory proteins, for regulation of either the local synthesis of channels in the dendrite or the activity or kinetic properties of the channel on the cell membrane. Because the Kv1 voltage-gated potassium channels reside on both dendrites and axons, the mosaic analysis with double markers (MADM) approach will be employed to study the physiological role of dendritic Kv1 channels.
