促肾上腺皮质激素释放激素 (CRH) 与多巴胺能系统之间的相互作用主要在成瘾和奖赏方面进行研究,而 CRH-多巴胺在焦虑中的相互作用却知之甚少。我们描述了扩展杏仁核中一群新的表达 CRH、GABA 能、长程投射的神经元,它们支配腹侧被盖区,并改变慢性 CRH 耗竭后的焦虑。这些神经元是独特的 CRH 回路的一部分,通过正向调节多巴胺的释放来发挥抗焦虑作用。
The interplay between corticotropin-releasing hormone (CRH) and the dopaminergic system has predominantly been studied in addiction and reward, while CRH-dopamine interactions in anxiety are scarcely understood. We describe a new population of CRH-expressing, GABAergic, long-range-projecting neurons in the extended amygdala that innervate the ventral tegmental area and alter anxiety following chronic CRH depletion. These neurons are part of a distinct CRH circuit that acts anxiolytically by positively modulating dopamine release.
