甲神经元 (PB) 的化学遗传抑制改变了味觉反应. 抑制这些神经元减少了类避免,但也减少了男性的糖糖偏好,表明在苦味和甜味感知中发挥了作用.
科学领域:
- 神经科学是一个神经科学.
- 感官生物学 感官生物学
- 行为科学 行为科学
背景情况:
- 副手臂 (PB) 核对于味道处理和感官集成至关重要.
- 表达卡尔卡基因的PB神经元与感官整合反应有关,但它们在味觉感知中的特定作用尚不清楚.
研究的目的:
- 为了研究化学基因抑制PB Calca神经元对小鼠对苦味和甜味刺激的口感偏好的影响.
- 探索PB Calca神经元在以品味为导向的行为中的性别特异性作用.
主要方法:
- 使用Cre-依赖的病毒载体进行化学遗传操纵,以在Calca-Cre小鼠的PB Calca神经元中表达抑制设计受体hM4Di.
- 进行了短期接触液体暴露测试,以测量对素,环胺和糖溶液的行为.
- 在施用克洛扎-N-氧化物 (CNO) 激活hM4Di受体后,进行了行为实验.
主要成果:
- 抑制PB Calca神经元导致减少避免氨酸,但不是循环胺,这表明对苦味感知有差异性影响.
- 具有抑制PB Calca神经元的雄性小鼠表现出选择性减少糖的偏好.
- 这些发现表明,PB Calca神经元调节对厌恶性和食欲性味道刺激的反应,对甜味有性别相关的影响.
结论:
- PB Calca神经元在调节口感偏好和以味道为导向的行为方面发挥着重要作用.
- 在食欲味道处理中的PB Calca神经元的功能取决于性别.
- 这些神经元有助于将味道信息与其他感官模式整合起来.
