摘要

为探讨刺山柑果实正丁醇相(Capparis spinosa L. fruit n-Butanol Extract

CSBE)对小鼠树突状细胞(Dendritic Cell

DC)成熟的影响及其作用机理，用1、2、3 mg·mL-1的CSBE处理DC，采用流式细胞术和ELISA检测DC表面标志物、抗原吞噬能力和细胞因子分泌验证DC成熟度．采用液相色谱-质谱联用(LC-MS)鉴定CSBE抗炎活性成分，基于网络药理学分析其在类风湿性关节炎(Rheumatoid Arthritis

RA)的相关靶点．利用String数据库和Cytoscape 3.7.2软件构建关键靶点蛋白质-蛋白质互作(Protein-Protein Interaction

PPI)网络，利用Metascape平台进行GO和KEGG富集分析并用western blot检测相关蛋白的表达．实验结果显示：CSBE单独处理时对DC表面共刺激分子和细胞因子没有显著影响，但显著抑制了细菌脂多糖(Lipopolysaccharides

LPS)诱导的DC表面分子CD40和CD86的表达、细胞因子TNF-α和IL-6的分泌以及基质金属蛋白酶MMP9和MMP13的表达，增加了抗原吞噬能力．LC-MS正离子模式下有49种抗炎化合物，负离子模式下有42种抗炎化合物．抗炎化合物在RA中共有核心靶点包括AKT1、TNF、SRC及MMP9等，其中有机酸类化合物主要关联辅助性T细胞的分化、Th17辅助性细胞的分化、Th17型免疫反应等Th17相关的生物学过程，涉及PI3K-AKT信号通路、Th17细胞分化、HIF-1信号通路和IL-17信号通路等类风湿性关节炎相关的信号通路．CSBE能够抑制DC的成熟及促炎细胞因子的表达，通过降低MMP表达抑制DC迁移，从而发挥免疫抑制及治疗RA的功能．

Abstract

This study investigated the effect and mechanism of Capparis spinosa L. fruit n-butanol extract(CSBE)on the maturation of dendritic cell(DC). DC was treated with 1

3 mg·mL-1 CSBE. DC surface molecule expression

antigen phagocytosis and cytokine secretion were determined by fow cytometry and ELISA to verify DC maturity. Liquid chromatography-mass spectrometry(LC-MS) was used to identify anti-infammatory components of CSBE and network pharmacology was utilized to analyze their targets related to rheumatoid arthritis(RA).String database and Cytoscape 3.7.2 software were utilized to construct protein-protein interaction(PPI) network maps of the key targets

and Metascape platform was used for GO and KEGG enrichment analysis and western blot was used to identify the expression of related proteins. The experiment results showed that CSBE alone had no significant effect on the expression of DC co-stimulatory molecules and cytokines

but significantly inhibited the expression of CD40 and CD86

matrix metalloproteinases MMP9 and MMP13

and the secretion of TNF-αand IL-6 induced by bacterial lipopolysaccharides(LPS). CSBE also increased antigen phagocytosis of DC. There were 49 anti-infammatory compounds in the positive ion mode of LC-MS

and 42 anti-infammatory compounds in the negative ion mode. Common core targets include AKT1

TNF

SRC and MMP9. Among them

organic acids are mainly associated with Th17-related biological processes such as helper T cell differentiation

Th17 helper cell differentiation

Th17 type immune response

et al.. It involves PI3K-AKT signaling pathway

Th17 cell differentiation

HIF-1 signaling pathway

and IL-17 signaling pathway related to RA. CSBE can inhibit the maturation of DC and the expression of pro-infammatory cytokines

and inhibit DC migration by reducing the expression of MMP

thus exerting the function of immunosuppression and treatment of RA.
