多发性硬化铜死亡基因的免疫浸润机制及潜在中药治疗预测OA北大核心CSTPCD

Immune infiltration mechanism of cuproptosis genes in multiple sclerosis and prediction of potential Chinese medicine treatment

中文摘要英文摘要

目的:分析铜死亡基因在多发性硬化(MS)发生发展过程中与免疫浸润的相关性,并进行中药预测,为铜死亡在MS免疫浸润方面的机制研究及中药干预免疫调节提供理论依据.方法:通过GEO数据库下载MS的芯片并进行标准化处理;基于处理后的数据进行免疫细胞和功能的提取与量化,分析免疫细胞和功能的相关性及差异性;同时筛选出与MS相关的铜死亡基因,构建风险模型,并对其进行富集分析;对铜死亡基因及免疫相关的生物过程进行中药预测.结果:①免疫细胞间,滤泡辅助性T细胞和B细胞呈最强正相关;免疫功能间,低度炎症和Ⅰ型IFN反应呈最强正相关;②B细胞、辅助性T细胞、人类白细胞抗原在MS患者中丰度显著降低,而主要组织相容性复合体Ⅰ类分子、低度炎症、Ⅰ型IFN反应丰度显著升高;③与MS相关的铜死亡基因为SLC31A1、PDHA1、NLRP3、MTF1、GLS和DBT,其中DBT最有可能是MS的风险因子;④MS发生发展涉及IL-4的产生、辅助性T细胞分化、急性炎症反应等生物过程,与精氨酸生物合成、柠檬酸循环、丙酸代谢等通路相关;⑤半夏、丹参、姜黄等中药可能作为其潜在的分子药物来源.结论:铜死亡基因的表达与MS相关免疫细胞和功能密切相关,可为MS的基础研究提供支持.

Objective:To analyze the correlation between cuproptosis genes and immune infiltration during the occurrence and development of multiple sclerosis(MS),and to predict the traditional Chinese medicine,to provide theoretical basis for the mecha-nism study of cuproptosis in MS immune infiltration and Chinese medicine to intervene in immune regulation.Methods:The gout chip of MS was downloaded from the GEO database and standardized;based on the processed data,immune cells and functions were ex-tracted and quantified,and the correlation and differences of immune cells and functions were analyzed;at the same time,cuproptosis genes related to MS were screened out,a risk model was constructed,and enrichment analysis was carried out;the prediction of cu-proptosis genes and immune-related biological processes were carried out.Results:① Among immune cells,T follicular helper cell and B cell showed the strongest positive correlation;among the immune functions,parainflammation and typeⅠIFN reponse showed the strongest positive correlation;②B cell,T helper cell and human leukocyte antigen were lowly expressed in MS patients,while major histocompatibility complex class Ⅰ,parainflammation and typeⅠIFN response were significantly expressed;③ The cupropto-sis genes associated with MS were SLC31A1,PDHA1,NLRP3,MTF1,GLS and DBT,of which DBT was the most likely risk factor for MS;④The occurrence and development of MS involves biological processes such as IL-4 production,T-helper cell differentiation,and acute inflammatory response,which were related to pathways such as arginine biosynthesis,citrate cycle,and propanoate metabo-lism;⑤Banxia,Danshen,Jianghuang and other traditional Chinese medicines may be used as potential molecular drug sources.Con-clusion:The expression of cuproptosis gene is closely related to MS-related immune cells and functions,which can provide support for the basic research of MS.
