有越来越多的证据表明,神经营养素在精神分裂症等神经精神疾病中发生了变化,此外,已知在精神分裂症中受到不利影响的神经递质(如多巴胺)可以通过G蛋白偶联受体激活神经营养素信号通路。然而,目前还不清楚精神分裂症使用的主要治疗药物如何影响神经营养素信号传递。考虑到目前所有处方的抗精神病药物都是多巴胺受体的配体,这一点很重要。在这项研究中,评估了具有代表性的传统和第二代抗精神病药物对大鼠神经生长因子(NGF)受体水平的慢性影响。结果表明,在所分析的任何脑区,药物对TrkA水平都没有显著影响;然而,所分析的五种抗精神病药物中,有三种显著降低了海马区的磷酸化TrkA(即受体的激活形式)。这些数据表明,慢性抗精神病药物治疗可能会对大脑中一个重要的信息处理和认知区域的神经营养因子信号产生有害影响。
There is growing evidence of neurotrophin alterations in neuropsychiatric illnesses such as schizophrenia and further, neurotransmitters known to be adversely affected in schizophrenia (e.g. dopamine) can activate neurotrophin signalling pathways via G protein-coupled receptors. However, it is unclear how the primary therapeutic agents used in schizophrenia affect neurotrophin signalling. This is important given that all currently prescribed antipsychotic drugs serve as ligands at dopamine receptors. In this study, chronic effects of representative conventional and second-generation antipsychotics on nerve growth factor (NGF) receptor levels were assessed in the rat. The results indicated no significant drug effects on TrkA levels in any brain region analysed; however, three of the five antipsychotics analysed significantly decreased phospho-TrkA (i.e. the activated form of the receptor) in the hippocampus. These data indicate that chronic antipsychotic treatment may result in deleterious effects on neurotrophin signalling in an important brain region for information processing and cognition.
