摘要: 【摘要】 机体可以通过氨基酸代谢调控免疫应答,在自身免疫性疾病的发病过程中发挥作用。银屑病是一种常见的慢性自身免疫性皮肤疾病,其发病机制涉及到树突细胞、T细胞等免疫细胞的调节失衡。越来越多的证据表明,银屑病中特定氨基酸的水平失调及代谢过程与其发病机制之间互相关联,其中研究相对较多的是色氨酸和精氨酸的代谢。色氨酸和精氨酸代谢通过调控免疫应答在银屑病发病中起到重要作用,亦可能提供新的治疗靶点。本综述分别对色氨酸和精氨酸的代谢过程及对免疫系统的调节作用进行总结,并阐述其在银屑病发病作用中的研究进展,旨在以新的视角理解银屑病的发病机制,有助于提供疾病干预的新思路。

Abstract: 【Abstract】 Amino acid metabolism plays a key role in regulating immune responses and in the pathogenesis of autoimmune diseases. Psoriasis is a common chronic autoimmune skin disease, whose pathogenesis involves the imbalance of dendritic cells, T cells and other immune cells. Growing evidence indicates that the imbalance of certain amino acids and their metabolic process in psoriasis are related to the pathogenesis of psoriasis, with tryptophan and arginine metabolism being relatively well-studied. They play important roles in the pathogenesis of psoriasis by regulating immune response, and may also provide new therapeutic targets. This review summarizes the metabolic process of tryptophan and arginine as well as their regulatory effects on the immune system, and discusses the current research advances regarding their roles in the pathogenesis of psoriasis, aiming to provide a novel perspective on the pathogenesis of psoriasis, potentially facilitating new approaches for disease intervention.
