纹状体主要由中等多刺投射神经元组成,其余神经元由几种类型的中间神经元组成。在中间神经元中有一组表达酪氨酸羟化酶(TH)的细胞。虽然这些TH-表达的中间神经元的固有电特性的特点,有TH-表达细胞类型和它们的电特性的数量没有协议。在这里,我们使用了转基因小鼠,其中YFP标记的通道视紫红质-2(ChR 2)在潜在的TH表达细胞中以Cre依赖的方式表达。我们发现,在纹状体的YFP+神经元是异质性的内在电特性,无偏聚类表明,有三个主要的神经元亚型。一个神经元群体具有具有高频动作电位(AP)放电和平台电位的刺状树突,类似于先前描述的TH中间神经元(THIN)。第二,非常小的标记神经元的人口类似于中型多刺神经元(MSN)。第三个群体的神经元树突与中间密度的棘,表现出实质性的AP适应,并产生长期的尖峰。这种类型的纹状体神经元以前没有在成年小鼠中被发现,我们将其命名为具有棘的频率适应神经元(FANS)。由于其独特的性质,FANS可能在纹状体信息处理中发挥独特的作用。
The striatum is predominantly composed of medium spiny projection neurons, with the remaining neurons consisting of several types of interneurons. Among the interneurons are a group of cells that express tyrosine hydroxylase (TH). Although the intrinsic electrical properties of these TH-expressing interneurons have been characterized, there is no agreement on the number of TH-expressing cell types and their electrical properties. Here, we have used transgenic mice in which YFP-tagged channelrhodopsin-2 (ChR2) was expressed in potential TH-expressing cells in a Cre-dependent manner. We found that the YFP+ neurons in the striatum were heterogeneous in their intrinsic electrical properties; unbiased clustering indicated that there are three main neuronal subtypes. One population of neurons had aspiny dendrites with high-frequency action potential (AP) firing and plateau potentials, resembling the TH interneurons (THIN) described previously. A second, very small population of labeled neurons resembled medium-sized spiny neurons (MSN). The third population of neurons had dendrites with an intermediate density of spines, showed substantial AP adaptation and generated prolonged spikes. This type of striatal neuron has not been previously identified in the adult mouse and we have named it the Frequency-Adapting Neuron with Spines (FANS). Because of their distinctive properties, FANS may play a unique role in striatal information processing.
