中文摘要
在程序性细胞死亡中,凋亡分子从线粒体的释放被促凋亡Bcl-2蛋白激活。我们首先询问促凋亡Bcl-2蛋白是否在长期抑郁症(LTD)中激活线粒体。我们将改变海马神经元中促凋亡蛋白Bcl-2的表达,然后检测这些神经元中-氨基-3-羟基-5-甲基异恶唑-4-丙酸(AMPA)受体的内吞和LTD。为了研究casapses如何介导AMPA受体的内吞作用,我们将使用抗体对caspase-3的免疫沉淀蛋白,结合到caspase-3在LTD。我们已经提出了一个结构过度表达caspase-3在海马神经元,并正在进行免疫沉淀实验。
英文摘要
The release of apoptotic molecules from mitochondria is activated by the pro-apoptotic Bcl-2 proteins in programmed cell death. We first ask whether the pro-apoptotic Bcl-2 proteins activate mitochondria in long-term depression (LTD). We will alter the expression of pro-apoptotic Bcl-2 proteins in hippocampal neurons, then examine -amino-3-hydroxy-5-methylisoxazole-4- propionic acid (AMPA) receptor endocytosis and LTD in these neurons. To investigate how casapses mediate AMPA receptor endocytosis, we will use antibodies against caspase-3 to immunoprecipitate proteins that bind to caspase-3 in LTD. We have made a construct to overexpress caspase-3 in hippocampal neurons and are performing the immunoprecipitation experiment.
