成人神经发生现在被广泛认为是海马体完整性和功能的重要贡献者,但当成人神经发生在酒精使用障碍等神经精神疾病中受到影响时,也会出现功能障碍。过量饮酒是酒精使用障碍的明显特征,会导致各种认知和行为障碍,完全或部分与海马体结构和功能有关。最近的临床前研究表明,成人神经发生可能是酒精引起海马神经病理的一条途径。酒精是一种药理混杂的药物,能够通过多种机制干扰成人的神经发生。本文将讨论酒精改变成年海马神经发生的主要机制,包括酒精对神经递质、CREB及其下游效应和神经源性生态位的影响。
Adult neurogenesis is now widely accepted as an important contributor to hippocampal integrity and function but also dysfunction when adult neurogenesis is affected in neuropsychiatric diseases such as alcohol use disorders. Excessive alcohol consumption, the defining characteristic of alcohol use disorders, results in a variety of cognitive and behavioral impairments related wholly or in part to hippocampal structure and function. Recent preclinical work has shown that adult neurogenesis may be one route by which alcohol produces hippocampal neuropathology. Alcohol is a pharmacologically promiscuous drug capable of interfering with adult neurogenesis through multiple mechanisms. This review will discuss the primary mechanisms underlying alcohol-induced changes in adult hippocampal neurogenesis including alcohol's effects on neurotransmitters, CREB and its downstream effectors, and the neurogenic niche.
