脑源性神经营养因子(BDNF)和B细胞淋巴瘤-2(Bcl - 2)蛋白是参与神经元信号传导、存活和可塑性的神经保护因子。两者均可受环磷腺苷效应元件结合蛋白(CREB)调节。BDNF和Bcl - 2水平降低与双相情感障碍的发病机制有关。本研究探讨了长期给大鼠使用情绪稳定剂是否会增加脑中BDNF和/或Bcl - 2的水平。采用实时逆转录聚合酶链反应(RT - PCR)、夹心酶联免疫吸附测定(ELISA)和蛋白质印迹法来测量长期给予卡马西平(CBZ)或拉莫三嗪(LTG)以产生与双相情感障碍治疗相关的血浆浓度的大鼠额叶皮质中BDNF和Bcl - 2的信使核糖核酸(mRNA)及蛋白水平。慢性CBZ和LTG显著增加了额叶皮质中BDNF和Bcl - 2的mRNA及蛋白水平。情绪稳定剂治疗双相情感障碍的一种常见作用机制可能涉及通过上调脑中BDNF和Bcl - 2的表达来介导神经保护作用。
Brain-derived neurotrophic factor (BDNF) and B-cell lymphoma-2 (Bcl-2) proteins are neuroprotective factors involved in neuronal signaling, survival and plasticity. Both can be regulated by cyclic AMP response element binding (CREB) protein. Decreased levels of BDNF and Bcl-2 are implicated in the pathogenesis of bipolar disorder. The present study investigated whether chronically administered mood stabilizers to rats would increase BDNF and/or Bcl-2 levels in brain. Real time RT-PCR, sandwich ELISA and Western blotting were used to measure BDNF and Bcl-2 mRNA and protein levels in the frontal cortex of rats chronically administered carbamazepine (CBZ) or lamotrigine (LTG) to produce plasma concentrations therapeutically relevant to bipolar disorder. Chronic CBZ and LTG significantly increased BDNF and Bcl-2 mRNA and protein levels in the frontal cortex. A common mechanism of action of mood stabilizers in the treatment of bipolar disorder may involve neuroprotection mediated by upregulation of brain BDNF and Bcl-2 expression.
