成人神经发生发生在两个特殊的微环境中,海马齿状回的颗粒下区和侧脑室沿着的脑室下区(SVZ)。这篇综述的重点是积累证据表明,特定的大脑区域或身体状态的活动影响SVZ细胞增殖和神经发生。多巴胺和血清素等神经调节剂已被证明通过神经元投射到SVZ中具有长期作用。局部GABA和谷氨酸信号传导对SVZ增殖和神经发生有影响,但这些神经递质的额外利基来源仍有待探索,并将讨论各种选择。也有越来越多的证据表明,疾病和身体状态,如阿尔茨海默病,癫痫发作,睡眠和怀孕影响SVZ细胞增殖。由于这种复杂的行为和控制亚区域特异性活动的环境驱动因素,在开发细胞疗法或药物治疗时,有必要考虑多种神经递质系统对神经发生的重叠作用。
Adult neurogenesis occurs in two privileged microenvironments, the hippocampal subgranular zone of the dentate gyrus and the subventricular zone (SVZ) along the lateral ventricle. This review focuses on accumulating evidence suggesting that the activity of specific brain regions or bodily states influences SVZ cell proliferation and neurogenesis. Neuromodulators such as dopamine and serotonin have been shown to have long-range effects through neuronal projections into the SVZ. Local GABA and glutamate signaling have demonstrated effects on SVZ proliferation and neurogenesis, but an extra-niche source of these neurotransmitters remains to be explored and options will be discussed. There is also accumulating evidence that diseases and bodily states such as Alzheimer's disease, seizures, sleep, and pregnancy influence SVZ cell proliferation. With such complex behavior and environmentally-driven factors that control subregion-specific activity, it will become necessary to account for overlapping roles of multiple neurotransmitter systems on neurogenesis when developing cell therapies or drug treatments.
