项目摘要
In the present study, we aimed to develop a novel technology for excitatory and inhibitory control of the activity of target neuronal types. A single chain variable region of anti-Tac monoclonal antibody against human interleukin-2 receptor a-subunit was fused to Fc fragment[anti-Tac(Fv)-Fc] was bound to liposome to produce immunoliposome. Anti-Tac(Fv) was connected to the transmembrane domain of vesicular somatitis virus glycoprotein or VSV-G[anti-Tac(Fv)-VSV-G], and anti-Tac(Fv)-VSV-G was expressed in insect cells by the baculoviral vector system. These cells were fused to loposome to generate proteoliposome containing anti-Tac(Fv)-VSV-G. We succeeded in the reduction of nonspecific binding of immunoliposome and proteoliposome by adding unlabelled control liposome into the solution containing the rhodamine-labelled liposome. This strategy will be useful to control the activity of neurons by introducing some drugs that inhibit ion channels into immunoliposome or proteoliposome.
在本研究中,我们的目标是开发一种对目标神经元类型的活动进行兴奋和抑制控制的新技术。将抗人白细胞介素2受体α亚基的抗Tac单克隆抗体的单链可变区与Fc片段融合[抗Tac(Fv)-Fc]与脂质体结合,产生免疫脂质体。 Anti-Tac(Fv)与水泡性口炎病毒糖蛋白或VSV-G的跨膜结构域连接[anti-Tac(Fv)-VSV-G],anti-Tac(Fv)-VSV-G在昆虫细胞中表达通过杆状病毒载体系统。这些细胞与脂质体融合,生成含有抗 Tac(Fv)-VSV-G 的蛋白脂质体。我们通过将未标记的对照脂质体添加到含有罗丹明标记的脂质体的溶液中,成功地减少了免疫脂质体和蛋白脂质体的非特异性结合。通过将一些抑制离子通道的药物引入免疫脂质体或蛋白脂质体,该策略将有助于控制神经元的活动。
