The atypical antipsychotic drugs (AAPDs) have markedly enhanced the treatment of schizophrenias but their use has been hindered by the major weight gain elicited by some AAPDs. We report that orexigenic AAPDs potently and selectively activate hypothalamic AMP-kinase, an action abolished in mice with deletion of histamine H1 receptors. These findings may afford a means of developing more effective therapeutic agents and provide insight into the hypothalamic regulation of food intake.
非典型抗精神病药物(AAPDs)显著改善了精神分裂症的治疗,但某些AAPDs引起的显著体重增加阻碍了它们的使用。我们报告促食欲的AAPDs能有效且选择性地激活下丘脑AMP激酶,在组胺H1受体缺失的小鼠中该作用消失。这些发现可能为开发更有效的治疗药物提供一种方法,并深入了解下丘脑对食物摄入的调节。
