Spadin 是一个强效的TREK-1 channel 抑制剂(IC50=71nM). 这是一个分泌的多肽,它来自由成熟的NTSR3/Sortilin 生成的前导肽。[1]
TREK1, 又名KCNK2, 是一个双孔蛋白结构域的离子通道,在被动的细胞钾离子跨膜交换中起着作用。 它和局部缺血,感觉缺失和电生成作用有关。它在抑郁症的病理学中和抗抑郁药物的反应中也起着重要作用。[1]
在TREK-1 转染的COS-7细胞中,100nM Spadin 能够抑制63% 的由花生酸刺激产生的TREK-1电流。在野生型小鼠脑切片的CA3海马神经元上, Spadin 也可以阻碍TREK-1 channel的活性。[1]
在预测抗抑郁反应的行为测试中,spadin 给药的小鼠显示出对抑郁的抵抗力。连续给小鼠用药四天,不但表现出很强的抗抑郁效果,并且也助长了海马CREB蛋白的磷酸化和神经系统发育。[2]
