[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。
