摘要

氨基酸作为机体所有细胞生存所必需的营养物质，其代谢过程与肿瘤的发生发展有着紧密联系。必需氨基酸色氨酸（tryptophan，TRP）的代谢改变对肿瘤微环境的影响具有重要意义，色氨酸主要通过吲哚胺2，3-双加氧酶（indoleamine 2，3-dioxygenase，IDO）、色氨酸-2，3-双加氧酶（tryptophan 2，3-dioxygenase，TDO）代谢为犬尿氨酸（kynurenine，KYN），犬尿氨酸的积累以及色氨酸的缺乏造成肿瘤微环境中免疫状态的改变，从而影响肿瘤的发生发展。该综述通过目前对色氨酸的研究，系统讨论了色氨酸代谢异常对肿瘤的影响以及针对该途径的干预措施，为后续的肿瘤治疗提供参考意见。

Abstract

Amino acids are essential nutrients for the survival of all cells in the body，and their metabolic processes are closely associated with tumor development and progression. The metabolic changes of the essential amino acid tryptophan have a significance impact on tumor microenvironment. Tryptophan is mainly metabolized to kynurenine （KYN） by indoleamine 2，3-dioxygenase and tryptophan 2，3-dioxygenase，and the accumulation of KYN and the deficiency of tryptophan cause alterations in the immune status in tumor microenvironment，which in turn affects tumor development and progression. Based on the current studies on tryptophan，this article systematically discusses the influence of abnormal tryptophan metabolism on tumors and the interventions targeting this pathway，in order to provide a reference for subsequent tumor therapy.
