我们建立了正常大鼠视网膜的代谢和功能图谱,前提是:1)氨基酸神经化学反映了代谢完整性和细胞特性,2)阳离子通道探针胍丁胺(1-氨基-4-胍基丁烷,AGB)的渗透反映了阳离子通道功能。其目的是提供一种独特的方法,同时评估正常视网膜的代谢和功能特征,据此可以与疾病模型进行比较。重叠的氨基酸和AGB表达谱的定量模式识别分析被用来提供一个统计学上的强大的分类所有的神经元素,根据他们的代谢和功能特性。该分类在空间上是完整的,并且具有单细胞分辨率。由此产生的分类表明,28个统计上可分离的主题类占主导地位的特征谷氨酸,GABA,甘氨酸,和/或牛磺酸配置文件,每个神经元主题类包含进一步的亚型。包括在分类过程中的功能参数(AGB映射)的神经元素,可以归因于一个神经化学/阳离子配置文件的数量几乎翻了一番,相比,当单独使用氨基酸标记。在水平细胞、视杆双极细胞、胆碱能无长突细胞和AII无长突细胞中观察到强的内源性谷氨酸门控AGB标记。所得氨基酸和AGB谱矩阵构成用于评估眼部疾病模型中对实验挑战的细胞应答的列线图。J.

We established a metabolic and functional profile map of the normal rat retina, given the premise that: 1) amino acid neurochemistry reflects metabolic integrity and cellular identity, and 2) the permeation of a cation channel probe, agmatine (1‐amino‐4‐guanidobutane, AGB), reflects cation channel functionality. The purpose was to provide a unique method of simultaneously assessing the metabolic and functional characteristics of the normal retina, upon which a comparison can be made to disease models. Quantitative pattern recognition analysis of overlapping amino acid and AGB expression profiles was used to provide a statistically robust classification of all neural elements according to their metabolic and functional characteristics. This classification was spatially complete and with single‐cell resolution. The resulting classification demonstrated 28 statistically separable theme classes dominated by characteristic glutamate, GABA, glycine, and/or taurine profiles, with each of the neuronal theme classes containing further subtypes. The inclusion of a functional parameter (AGB mapping) in the classification process nearly doubled the number of neural elements that could be ascribed a neurochemical/cation profile, compared to when amino acid labeling was used alone. Strong endogenous glutamate gated AGB labeling was observed in horizontal cells, rod bipolar cells, cholinergic amacrine cells, and AII amacrine cells. The resulting amino acid and AGB profile matrix constitutes a nomogram for assessing cellular responses to experimental challenges in models of ocular disease. J. Comp.
