采用脑内微透析结合高灵敏度放射免疫分析法,研究了自由活动大鼠杏仁核内神经肽S(NPs)的体内释放。在基底外侧杏仁核透析液中始终检测到α-淀粉样蛋白,并在局部去极化和强迫游泳应激下释放显著增强。因此,我们的数据表明,第一次情绪压力引起的释放杏仁核支持功能的内源性神经元的压力/焦虑相关的现象中的作用。
Intracerebral microdialysis in conjunction with a highly sensitive radioimmunoassay was used to study the in vivo release of neuropeptide S (NPS) within the amygdala of freely moving rats. NPS was consistently detected in basolateral amygdala dialysates and the release considerably enhanced in response to local depolarisation as well as exposure to forced swim stress. Thus, our data demonstrate for the first time emotional stress-induced release of NPS in the amygdala supporting a functional role of endogenous NPS in stress/anxiety-related phenomena.
