Studies have demonstrated that epigenetic changes such as DNA methylation, histone modification, and chromatin remodeling are linked to an increased inflammatory response as well as increased risk of chronic disease development. A few studies have begun to investigate whether dietary nutrients play a beneficial role by modifying or reversing epigenetically induced inflammation. Results of these studies show that nutrients modify epigenetic pathways. However, little is known about how nutrients modulate inflammation by regulating immune cell function and/or immune cell differentiation via epigenetic pathways. This overview will provide information about the current understanding of the role of nutrients in the epigenetic control mechanisms of immune function.
研究表明,诸如DNA甲基化、组蛋白修饰和染色质重塑等表观遗传变化与炎症反应增加以及慢性病发展风险增加有关。一些研究已开始探究膳食营养素是否通过改变或逆转表观遗传诱导的炎症发挥有益作用。这些研究结果表明,营养素可改变表观遗传途径。然而,关于营养素如何通过表观遗传途径调节免疫细胞功能和/或免疫细胞分化来调节炎症,我们知之甚少。本综述将提供有关目前对营养素在免疫功能表观遗传控制机制中作用的理解的信息。
