锌(Zn)是细胞生长、分化和存活等基本细胞活动所必需的微量营养素。锌缺乏抑制先天性和适应性免疫反应。然而,锌介导的免疫系统调节的确切生理机制在很大程度上尚不清楚。锌的体内平衡是由锌转运蛋白和金属硫蛋白的协同作用紧密控制的,金属硫蛋白调节锌的转运、分布和储存。越来越多的证据表明,锌的行为像一个信号分子,促进各种信号级联反应的细胞外刺激的转导。在这篇综述中,我们强调了锌和锌转运蛋白在免疫中的新功能作用,重点是锌和免疫相关信号之间的串扰如何引导免疫细胞的正常发育和功能。
Zinc (Zn) is an essential micronutrient for basic cell activities such as cell growth, differentiation, and survival. Zn deficiency depresses both innate and adaptive immune responses. However, the precise physiological mechanisms of the Zn-mediated regulation of the immune system have been largely unclear. Zn homeostasis is tightly controlled by the coordinated activity of Zn transporters and metallothioneins, which regulate the transport, distribution, and storage of Zn. There is growing evidence that Zn behaves like a signaling molecule, facilitating the transduction of a variety of signaling cascades in response to extracellular stimuli. In this review, we highlight the emerging functional roles of Zn and Zn transporters in immunity, focusing on how crosstalk between Zn and immune-related signaling guides the normal development and function of immune cells.
