在孤独管 (NTS) 核中激活多个调节养的神经元组,更有效地抑制食物摄入. 结合非厌恶性神经元组可以增强食抑制,而不会导致避免.
科学领域:
- 神经科学是一个神经科学.
- 身体生理学 身体生理学
- 内分泌学 在内分泌学.
背景情况:
- 孤独通道 (NTS) 的核中含有多样化的神经元群体,调节养行为.
- 表达CCK,Lepr和Calcr的特定NTS神经元在抑制食物摄入方面发挥作用,其中一些促进避免,而另一些则不.
研究的目的:
- 研究不同调节养的NTS神经元群体之间的潜在协同相互作用.
- 为了确定多个NTS细胞组的同时操纵是否会对养和避开行为产生增强的效果.
主要方法:
- 同时激活和沉默不同的NTS神经元群体 (NTSCck,NTS麻风,NTSCalcr).
- 评估食抑制和有条件的味道回避 (CTA).
- 评估对体重的影响和对垂直袖子胃切除术 (VSG) 的反应.
主要成果:
- 激活多个NTS神经元组 (例如NTSLC,NTSLCK) 比激活单个群体更强大地抑制了食.
- 激活含有NTSCck组诱导了CTA,而NTSLC激活抑制了食而没有诱导避免.
- 沉默多个NTS神经元组比沉默单个组更多地增加了食物摄入量和体重.
结论:
- 在食调节的NTS神经元之间存在协同作用,增强了食抑制.
- 非厌恶性NTS神经元群体可以增加食抑制,而不会促进避免.
- 多个NTS神经元群体在能量平衡中起到累积作用,额外的未定义细胞类型有助于抑制食.
