Combinations of Patch-Clamp and Confocal Calcium Imaging in Acutely Isolated Adult Mouse Amygdala Brain Slices

[Abstract]  Calcium imaging is a powerful technique in the study of neuronal physiology, as it avoids the enzyme treatment on neurons and is able to study the neuronal activities in vivo. Using calcium-imaging techniques, we are able to monitor the elevation of calcium in the neuron. Furthermore, we can combine calcium imaging with other methods, like whole-cell patch clamp recordings, to detect a single cell calcium signal in brain slices. In this protocol, we describe a detailed confocal imaging method that is combined with whole-cell patch clamp configuration using brain slices (Du et al., 2017). [摘要]  钙成像是神经生理学研究中的一项强有力的技术,因为它避免了对神经元的酶处理,并且能够研究体内的神经元活动。 使用钙成像技术,我们能够监测神经元中钙的升高。 此外,我们可以将钙成像与其他方法结合起来,如全细胞膜片钳记录,以检测脑切片中的单细胞钙信号。 在该协议中,我们描述了一种详细的共焦成像方法,该方法与使用脑切片的全细胞膜片钳配置相结合(Du et al。,2017)。

【背景】几十年来,脑切片已成功用于研究突触,神经元和神经回路。许多实验操作已经应用于脑切片模型,例如药物应用,细胞内记录和光学成像。与培养的神经元相比,脑切片保留了神经元回路的许多基本功能特性。钙成像是一种广泛使用的技术,旨在表明分离的细胞和组织的细胞内钙(Ca 2 + )状态。研究脑组织中的细胞内钙可以深入了解各种生理过程,如细胞增殖,信号转导,突触可塑性和细胞死亡,因为钙浓度在这些功能中起着关键作用(Cameron et al。,2016)。钙指示剂是一种荧光分子,它与Ca 2 + ...

[Abstract]  Inositol triphosphate (IP3) is an important second messenger that participates in signal transduction pathways in diverse cell types including hippocampal neurons. Stimulation of phospholipase C in response to various stimuli (hormones, growth factors, neurotransmitters, neurotrophins, neuromodulators, odorants, light, etc.) results in hydrolysis of phosphatidylinositol 4, 5-bisphosphate (PIP2), a phospholipid that is located in the plasma membrane, and leads to the production of IP3 and diacylglycerol. Binding of IP3 to the IP3 receptor (IP3R) induces Ca2+ release from intracellular stores and enables the initiation of intracellular Ca2+-dependent signaling. Here we describe a procedure for ... [摘要]  肌醇三磷酸(IP3)是参与信号转导途径的重要的第二信使,包括海马神经元在内的不同细胞类型。 刺激磷脂酶C对各种刺激(激素,生长因子,神经递质,神经营养因子,神经调节剂,气味剂,光等)的反应导致磷脂酰肌醇4,5-二磷酸(PIP2)的水解,磷脂位于质膜 ,并导致IP3和二酰基甘油的生产。 IP3与IP3受体(IP3R)的结合诱导Ca2 +从细胞内储存释放,并使细胞内Ca2 +依赖信号的启动。 在这里,我们描述了从大鼠海马切片制备的组织匀浆中测量细胞IP3水平的程序。
