人类社会和情绪障碍的频率在男性和女性之间有很大差异。我们最近报道,催产素受体中间神经元(OxtrINs)调节女性的社会性行为。在这里,我们表明,在雄性小鼠中,OxtrINs调节焦虑相关的行为。我们证明,促肾上腺皮质激素释放激素结合蛋白(CRHBP),应激激素CRH的拮抗剂,是专门表达在OxtrINs。CRHBP的产生阻断了CRH诱导的雄性而非雌性小鼠突触后2/3层锥体细胞活性增强,从而产生抗焦虑作用。我们的数据确定OxtrINs作为调制的社会和情感行为的女性和男性的关键,并揭示了一种分子机制,作用于当地的mPFC电路,以协调响应OXT和CRH。他们认为,在男性和女性中对OXT/OXTR和CRHBP/CRH通路的影响进行额外的研究对于开发性别特异性治疗非常重要。
The frequency of human social and emotional disorders varies significantly between males and females. We have recently reported that oxytocin receptor interneurons (OxtrINs) modulate female sociosexual behavior. Here we show that in male mice OxtrINs regulate anxiety-related behaviors. We demonstrate that corticotropin releasing hormone binding protein (CRHBP), an antagonist of the stress hormone CRH, is specifically expressed in OxtrINs. Production of CRHBP blocks the CRH-induced potentiation of postsynaptic layer 2/3 pyramidal cell activity of male but not female mice, thus producing an anxiolytic effect. Our data identify OxtrINs as critical for modulation of social and emotional behaviors in both females and males, and reveal a molecular mechanism that acts on local mPFC circuits to coordinate responses to OXT and CRH. They suggest that additional studies of the impact of the OXT/OXTR and CRHBP/CRH pathways in males and females will be important in development of gender specific therapies.
