成年人的大脑齿状回在一生中都会产生新的神经元。它们结合在齿状回的颗粒细胞层中并整合在海马电路中。越来越多的证据表明,新的神经元在学习和记忆中发挥作用。反过来,大量的证据表明,阿尔茨海默病的神经发生受损,导致记忆缺陷。我们在这里概述了目前关于成年海马神经发生的生物学及其在学习和记忆中的功能的知识。此外,我们还讨论了阿尔茨海默病中神经发生功能障碍的证据,解决了有关成人和老年人大脑中海马神经发生持续存在的文献中的争议,并评估了基于神经发生的药物开发用于治疗阿尔茨海默病认知缺陷的治疗潜力。
New neurons are generated in the dentate gyrus of the adult brain throughout life. They incorporate in the granular cell layer of the dentate gyrus and integrate in the hippocampal circuitry. Increasing evidence suggests that new neurons play a role in learning and memory. In turn, a large body of evidence suggests that neurogenesis is impaired in Alzheimer’s disease, contributing to memory deficits characterizing the disease. We out-line here current knowledge about the biology of adult hippocampal neurogenesis and its function in learning and memory. In addition, we discuss evidence that neurogenesis is dysfunctional in Alzheimer’s disease, address the controversy in the literature concerning the persistence of hippocampal neurogenesis in the adult and aging human brain, and evaluate the therapeutic potential of neurogenesis-based drug development for the treatment of cognitive deficits in Alzheimer’s disease.
