摘要
磷酸二酯酶(Phosphodiesterase,PDE)水解细胞内第二信使-环磷酸腺苷和环磷酸鸟苷,降低细胞内第二信使的含量,进而影响下游信号转导,调节细胞内的生命活动。磷酸二酯酶2(PDE2)是磷酸二酯酶大家族的成员之一,在中枢神经系统中分布广泛,尤其在海马和杏仁核部分密集,近年来越来越多的研究表明PDE2可能参与中枢神经系统疾病的调节,而相应的PDE2抑制剂可能具有治疗抑郁、焦虑和学习记忆障碍等中枢神经系统疾病前景。本文综述了PDE2在中枢神经系统疾病调节中的作用及其抑制剂在治疗相关疾病的应用。
Cyclic nucleotide Phosphodiesterases (PDEs) are the only known enzymes that catalyze the hydrolysis of cyclic AMP (cAMP) and cyclic GMP (cGMP) and thus are integral to the regulation of cyclic nucleotide signaling and cellular communication. PDE2 is a member of the super family and it is highly expressed in the limbic nervous system, including the amygdala, hippocampus, and hypothalamus, which are important for emotional and cognitive function. This review discusses the current state and future development in the burgeoning field of PDE2 in the central nervous system. It is becoming increasingly clear that PDE inhibitors have therapeutic potential for the treatment of neuropsychiatric disorders involving disturbances of mood, emotion, and cognition.
