Schizophrenia is one of the most common mental illnesses, with hereditary and environmental factors important for its etiology. All antipsychotics have in common a high affinity for monoaminergic receptors. Whereas hallucinations and delusions usually respond to typical (haloperidol-like) and atypical (clozapine-like) monoaminergic antipsychotics, their efficacy in improving negative symptoms and cognitive deficits remains inadequate. In addition, devastating side effects are a common characteristic of monoaminergic antipsychotics. Recent biochemical, preclinical and clinical findings support group II metabotropic glutamate receptors (mGluR2 and mGluR3) as a new approach to treat schizophrenia. This paper reviews the status of general knowledge of mGluR2 and mGluR3 in the psychopharmacology, genetics and neuropathology of schizophrenia.
精神分裂症是最常见的精神疾病之一,遗传和环境因素对其病因学很重要。所有抗精神病药物的共同特点是对单胺能受体具有高亲和力。虽然幻觉和妄想通常对典型(氟哌啶醇样)和非典型(氯氮平样)单胺能抗精神病药物有反应,但其改善阴性症状和认知缺陷的疗效仍然不足。此外,严重的副作用是单胺能抗精神病药物的共同特征。最近的生化、临床前和临床研究结果支持将II组代谢型谷氨酸受体(mGluR2和mGluR3)作为治疗精神分裂症的新方法。本文综述了mGluR2和mGluR3在精神分裂症的精神药理学、遗传学和神经病理学方面的一般知识现状。
