摘要:

过度炎症严重危害人体健康,为了验证植物乳植杆菌HCS03-001的抗炎功效并探讨其抗炎机理,以转基因中性粒细胞绿色荧光斑马鱼为模型,使用细菌脂多糖(lipopolysaccharide,LPS)诱导炎症发生,以吲哚美辛为阳性对照,探究10、20、40 mg·mL-1植物乳植杆菌HCS03-001的抗细菌性炎症功效。通过SwissTargetPrediction、GeneCards和DisGeNET数据库获取植物乳植杆菌代谢产物的主要成分和炎症靶点。靶点取交集后通过STRING数据库构建蛋白质-蛋白质相互作用(the protein-protein interaction,PPI)网络;使用Cytoscape 3.9.0构建菌株代谢产物“成分-靶点-炎症”网络;利用DAVID平台工具对共有靶点进行GO富集分析及KEGG通路富集分析。斑马鱼实验结果显示,不同剂量的HCS03-001均能降低斑马鱼卵黄囊中性粒细胞数量,其中高剂量(40 mg·mL-1)的效果与模型组相比达到显著水平(P<0.05)。网络药理学结果发现,植物乳植杆菌代谢产物缓解炎症的过程中,作用较强的活性成分主要是异吡啶硫胺素、吲哚乙醛和麦角硫因等,可能作用于甘油醛-3-磷酸脱氢酶(glyceraldehyde-3-phosphate dehydrogenase,GAPDH)、环氧合酶2(prostaglandin endoperoxide synthase 2,Ptgs2)、过氧化物酶体增生激活受体γ(peroxisome proliferator-activated receptor gamma,PPARγ)等核心靶点,富集结果显示影响最显著的生物学过程是对LPS的反应,涉及的细胞组分为细胞膜,影响最显著的通路为癌症通路。结果表明,植物乳植杆菌HCS03-001具有显著的抗细菌性炎症功效,其具体机制可能是代谢成分异吡啶硫胺素、吲哚乙醛和麦角硫因等通过抑制细菌LPS与机体细胞膜的结合,以及通过调控GAPDH、Ptgs2、PPARγ等关键靶点影响癌症相关通路实现的。

Abstract:

Excessive inflammation is seriously harmful to human health. The anti-inflammatory effect of Lactiplantibacillus plantarum HCS03-001 was verified and the anti-inflammatory mechanism was explored. Using transgenic neutrophil green fluorescent zebrafish as model, bacterial LPS was used to induce inflammation, and indomethacin was used as positive control to explore the anti-bacterial inflammatory effect of Lactiplantibacillus plantarum HCS03-001 of 10, 20 and 40 mg·mL-1. The main components and inflammatory targets of the metabolites of Lactiplantibacillus plantarum were obtained by SwissTargetPrediction, GeneCards and DisGeNET database. After the targets were intersected, the PPI network was constructed by STRING database, the metabolic product “component-target-inflammation” network was constructed by Cytoscape3.9.0, and the common targets were analyzed by GO enrichment analysis and KEGG pathway enrichment analysis using DAVID platform tools. The results of zebrafish experiment showed that different doses of HCS03-001 could reduce the number of neutrophils in zebrafish yolk sac, and the effect of high dose (40 mg·mL-1) was significantly higher than that of the model group. The results of network pharmacology showed that in the process of relieving inflammation, the main active components of Lactobacillus plantarum metabolites were isopyridine thiamine, indole acetaldehyde and ergothione, which may act on core targets such as GAPDH, Ptgs2 and PPARγ. The enrichment results showed that the most significant biological process was the response to LPS, the cell components involved were cell membranes, and the most significant pathway was cancer pathway. The results showed that Lactiplantibacillus plantarum HCS03-001 had a significant anti-bacterial inflammatory effect, and the specific mechanism may be that metabolic components such as isopyridine thiamine, indole acetaldehyde and ergothione affect cancer-related pathways by inhibiting the binding of bacterial LPS to the plasma membrane and regulating key targets such as GAPDH, Ptgs2 and PPARγ.
