With extensive use in industrial and agriculture applications, overexposure to heavy metals has become a global public health concern. The nervous system is vulnerable to many heavy metals, including cadmium, lead, and mercury. However, the knowledge about the underlying mechanisms of these metals' neurotoxicity is still very limited. Adult neurogenesis is a process of generating functional neurons from adult neural progenitor/stem cells (aNPCs), which plays an important role in cognitive function and olfaction. The studies of adult neurogenesis provide new insights into mechanisms of heavy metal neurotoxicity. This review summarizes the current research about the effects of heavy metals on adult neurogenesis and discusses their importance in understanding the mechanisms of heavy metals neurotoxicity, as well as challenges and future directions.
随着重金属在工农业中的广泛应用,过度接触重金属已成为全球公共卫生关注的问题。神经系统易受多种重金属影响,包括镉、铅和汞。然而,关于这些金属神经毒性潜在机制的了解仍然非常有限。成体神经发生是指从成年神经祖细胞/干细胞(aNPCs)产生功能性神经元的过程,其在认知功能和嗅觉中发挥重要作用。成体神经发生的研究为重金属神经毒性机制提供了新的见解。本综述总结了目前关于重金属对成体神经发生影响的研究,并讨论了它们在理解重金属神经毒性机制中的重要性,以及面临的挑战和未来方向。
