硒是一种必需的微量营养素,在发育和各种生理过程中起着至关重要的作用,包括影响免疫反应。免疫系统依赖于足够的膳食硒摄入,这种营养素主要通过与硒蛋白结合发挥其生物学作用。硒蛋白质组包含25个人类成员,具有广泛的功能。高通量组学方法和新的生物信息学工具的发展导致了关于硒和硒蛋白在人类免疫生物学中的作用的新见解。同样重要的是,已经出现了创新的实验系统来研究这些效应背后的分子机制。本文综述了目前对硒和硒蛋白在调节免疫细胞功能中的作用以及这些过程的失调如何导致炎症或免疫相关疾病的理解。
Selenium is an essential micronutrient that plays a crucial role in development and a wide variety of physiological processes including effect immune responses. The immune system relies on adequate dietary selenium intake and this nutrient exerts its biological effects mostly through its incorporation into selenoproteins. The selenoproteome contains 25 members in humans that exhibit a wide variety of functions. The development of high-throughput omic approaches and novel bioinformatics tools has led to new insights regarding the effects of selenium and selenoproteins in human immuno-biology. Equally important are the innovative experimental systems that have emerged to interrogate molecular mechanisms underlying those effects. This review presents a summary of the current understanding of the role of selenium and selenoproteins in regulating immune cell functions and how dysregulation of these processes may lead to inflammation or immune-related diseases.
