Objective

To investigate the role of trichostatin A (TSA) in regulating CD4+T cell subpopulations during Escherichia coli (E.coli) inflammatory infections.

Methods

Male mice (8 weeks old, weighing 22~25 g) were randomly divided into 3 groups (n=16): a dimethyl sulfoxide (DMSO) control group, an infection group (DMSO+E.coli), and an intervention group (E.coli+TSA). E.coli was administered via intraperitoneal injection at a concentration of 3×10⁸ CFU/mL to establish an infection model. The E.coli+TSA group was further subdivided into 3 subgroups based on different TSA concentrations (2.5, 5.0, 10.0 mg/kg). Then the samples were collected at different time points (12, 24, 48, 96 h) after TSA intervention. The efficacy of TSA in treating E.coli-induced inflammatory responses and its relationship with CD4+T cell subsets were evaluated by survival rate observation, body weight monitoring, histopathological staining for small intestine, ELISA detection, transcriptomics sequencing, flow cytometry and RT-qPCR analysis.

Results

Compared with the E.coli group, 5 mg/kg TSA significantly increased survival rate, suppressed body weight loss, improved pathological damage in the small intestinal, reduced serum TNF-α level in 24 h after infection (P<0.000 1), and elevated IL-10 level (P<0.05). Transcriptomic analysis revealed that 5 mg/kg TSA intervention for 24 h modulated the T cell differentiation signaling pathways, including those regulating FoxO, Th17, and Th1/2. Flow cytometry and RT-qPCR results showed that compared to the E.coli group, 5 mg/kg TSA down-regulated the expression of the Th17 cell marker RORγt in mice 96 h after infection while significantly up-regulated the expression of the Treg cell marker Foxp3 (P<0.05).

Conclusion

TSA may alleviate bacterial infectious inflammatory diseases by regulating the differentiation of CD4+T cells toward the Treg subset while simultaneously inhibiting their differentiation toward the Th17 subset, thereby suppressing the release of proinflammatory cytokines.

目的

探讨曲古抑菌素A(trichostatin A,TSA)调控CD4+T细胞亚群在大肠杆菌(Escherichia coli,E.coli)感染性炎症中的作用。

方法

采用完全随机设计,将8周龄、雄性小鼠(体质量22~25 g)分为(n=16):对照组(DMSO组)、感染组(DMSO+E.coli组)及干预组(E.coli+TSA组),其中E.coli+TSA组根据TSA不同浓度分为2.5、5.0、10.0 mg/kg 3个亚组。腹腔注射3×10⁸ CFU/mL E.coli,构建感染模型,并在TSA干预不同时间点(12、24、48、96 h)取材。通过生存率观察、体质量监测、小肠组织病理染色、ELISA、转录组测序、流式细胞术以及RT-qPCR等手段,评估TSA对E.coli感染性炎症的疗效及与CD4+T细胞亚群的关系。

结果

与DMSO+E.coli组相比,5.0 mg/kg TSA可显著提高感染小鼠的生存率,抑制体质量下降,改善小肠病理损伤,降低感染24 h小鼠血清中肿瘤坏死因子-α水平(P<0.000 1),提升白细胞介素-10水平(P<0.05)。转录组结果表明5.0 mg/kg TSA干预24 h后可以影响调控FoxO、Th17、Th1/2等T细胞分化的信号通路,同时流式细胞术和RT-qPCR结果显示相较于DMSO+E.coli组,5.0 mg/kg TSA能下调感染96 h后小鼠Th17细胞标志分子RORγt表达,同时明显上调Treg细胞标志分子Foxp3表达(P<0.05)。

结论

TSA可能是通过调控CD4+T细胞朝向Treg亚群分化同时抑制其向Th17亚群分化,从而抑制促炎因子释放来缓解细菌感染性炎症疾病。

目的

探讨曲古抑菌素A(trichostatin A,TSA)调控CD4+T细胞亚群在大肠杆菌(Escherichia coli,E.coli)感染性炎症中的作用。

方法

采用完全随机设计,将8周龄、雄性小鼠(体质量22~25 g)分为(n=16):对照组(DMSO组)、感染组(DMSO+E.coli组)及干预组(E.coli+TSA组),其中E.coli+TSA组根据TSA不同浓度分为2.5、5.0、10.0 mg/kg 3个亚组。腹腔注射3×10⁸ CFU/mL E.coli,构建感染模型,并在TSA干预不同时间点(12、24、48、96 h)取材。通过生存率观察、体质量监测、小肠组织病理染色、ELISA、转录组测序、流式细胞术以及RT-qPCR等手段,评估TSA对E.coli感染性炎症的疗效及与CD4+T细胞亚群的关系。

结果

与DMSO+E.coli组相比,5.0 mg/kg TSA可显著提高感染小鼠的生存率,抑制体质量下降,改善小肠病理损伤,降低感染24 h小鼠血清中肿瘤坏死因子-α水平(P<0.000 1),提升白细胞介素-10水平(P<0.05)。转录组结果表明5.0 mg/kg TSA干预24 h后可以影响调控FoxO、Th17、Th1/2等T细胞分化的信号通路,同时流式细胞术和RT-qPCR结果显示相较于DMSO+E.coli组,5.0 mg/kg TSA能下调感染96 h后小鼠Th17细胞标志分子RORγt表达,同时明显上调Treg细胞标志分子Foxp3表达(P<0.05)。

结论

TSA可能是通过调控CD4+T细胞朝向Treg亚群分化同时抑制其向Th17亚群分化,从而抑制促炎因子释放来缓解细菌感染性炎症疾病。

Objective

To investigate the role of trichostatin A (TSA) in regulating CD4+T cell subpopulations during Escherichia coli (E.coli) inflammatory infections.

Methods

Male mice (8 weeks old, weighing 22~25 g) were randomly divided into 3 groups (n=16): a dimethyl sulfoxide (DMSO) control group, an infection group (DMSO+E.coli), and an intervention group (E.coli+TSA). E.coli was administered via intraperitoneal injection at a concentration of 3×10⁸ CFU/mL to establish an infection model. The E.coli+TSA group was further subdivided into 3 subgroups based on different TSA concentrations (2.5, 5.0, 10.0 mg/kg). Then the samples were collected at different time points (12, 24, 48, 96 h) after TSA intervention. The efficacy of TSA in treating E.coli-induced inflammatory responses and its relationship with CD4+T cell subsets were evaluated by survival rate observation, body weight monitoring, histopathological staining for small intestine, ELISA detection, transcriptomics sequencing, flow cytometry and RT-qPCR analysis.

Results

Compared with the E.coli group, 5 mg/kg TSA significantly increased survival rate, suppressed body weight loss, improved pathological damage in the small intestinal, reduced serum TNF-α level in 24 h after infection (P<0.000 1), and elevated IL-10 level (P<0.05). Transcriptomic analysis revealed that 5 mg/kg TSA intervention for 24 h modulated the T cell differentiation signaling pathways, including those regulating FoxO, Th17, and Th1/2. Flow cytometry and RT-qPCR results showed that compared to the E.coli group, 5 mg/kg TSA down-regulated the expression of the Th17 cell marker RORγt in mice 96 h after infection while significantly up-regulated the expression of the Treg cell marker Foxp3 (P<0.05).

Conclusion

TSA may alleviate bacterial infectious inflammatory diseases by regulating the differentiation of CD4+T cells toward the Treg subset while simultaneously inhibiting their differentiation toward the Th17 subset, thereby suppressing the release of proinflammatory cytokines.

细菌感染是全球范围内影响人群健康的重要原因,其中大肠埃希菌(Escherichia coli,E.coli)致死率位居前列[1]。E.coli作为一种常见的肠道条件致病菌,正常情况下与人类共生,维护肠道微生态平衡[2]。然而,当机体免疫力下降或细菌数量异常增多时,E.coli将引发感染性炎症,导致机体免疫失衡,引起一系列疾病,如胃肠炎、结肠炎等[3-4],严重影响人们生活质量甚至危及生命。
T细胞是机体重要的适应性免疫细胞之一,可分为CD4+T细胞和CD8+T细胞,在维持机体免疫平衡和防止自身免疫疾病中发挥着重要作用[5-6]。细菌感染发生后,树突状细胞(dendritic cell,DC)通过抗原递呈使初始T细胞(naïve T cell,Th0)分化形成多种CD4+T细胞亚群,包括辅助性T细胞(helper T cell,Th)1、Th2、调节性T细胞(regulatory T cell,Treg)和Th17等,参与免疫应答,尤其是Treg的作用不容忽视。研究表明,在细菌感染初期,Treg能够通过分泌抑制性细胞因子如白细胞介素-10(interleukin-10,IL-10)和转化生长因子β(transforming growth factor-β,TGF-β)来抑制Th1和Th17的活化,从而减轻炎症反应[7-8]。在细菌感染后期,Treg的作用则更为复杂,既要继续抑制过度免疫反应,又要促进免疫记忆的形成[9-13]。尽管包括Treg在内的CD4+T细胞在感染导致的免疫失衡中起着重要作用,但现有研究仍不清楚调控其功能的关键因子。
曲古抑菌素A(trichostatin A,TSA)是一种有效的组蛋白脱乙酰酶(histone deacetylase,HDAC)抑制剂和抗真菌抗生素。近年来,越来越多的研究表明,TSA能够通过多种途径调控细胞凋亡、细胞周期等生物学过程,从而影响肿瘤和炎症性疾病的进展[14-16];CUI等[17]发现TSA可通过增强细胞自噬,促进巨噬细胞向抗炎M2表型极化,从而减轻多种微生物引起的脓毒症期间的炎症反应;胡晓兰等[18]研究发现TSA预处理后能显著降低LPS诱导的巨噬细胞中肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)、IL-1β等促炎因子的生成并降低TLR4的表达。此外,TSA还被发现能够影响多种CD4+T细胞亚群的活性[19]。但TSA是否对CD4+T细胞亚群分化具备调控作用尚不清楚。
本研究将探讨TSA对E.coli感染性炎症的治疗作用及与CD4+T细胞亚群之间的关系,为细菌感染性炎症的治疗提供实验依据和新策略。

所有结果采用GraphPad Prism 10.1.2软件进行统计和作图,计量资料用x¯±s表示。不同组别之间采用单因素方差分析,P<0.05表示差异具有统计学意义。生存率分析采用Log-rank检验方法。
通过向小鼠腹腔注射不同剂量体积的3×108 CFU/mL E.coli,发现注射剂量200 µL菌液后小鼠死亡率为50%~60%,低于其它剂量(图1A)。故后续实验均选择该注射剂量。与DMSO+E.coli组相比,E.coli+TSA组生存率明显提高,其中5.0 mg/kg TSA组小鼠在感染后14 d内全部存活(图1B)。尽管在建模后2 d内,DMSO+E.coli组和E.coli+TSA组(含不同浓度TSA亚组)体质量均大幅度下降,但E.coli+TSA组感染后第14天均恢复至与DMSO组无明显差异(图1C)。
相较于DMSO组,DMSO+E.coli组小肠绒毛受损严重、萎缩并伴随肠绒毛上皮脱落坏死,12和48 h可见明显的肠绒毛水肿,绒毛固有层与绒毛上皮细胞分离,组织间隙变大;此外感染后12 h,DMSO+E.coli组小肠可见明显出血,24 h出现炎性细胞浸润;干预组(E.coli+TSA)可减轻小肠受损情况,改善出血和炎性因子浸润,小肠绒毛恢复正常(图2)。采用不同剂量TSA干预后,小肠病理均得到改善,但仍有绒毛倒伏等情况。与2.5和10.0 mg/kg TSA干预相比,采用5.0 mg/kg TSA干预,小肠病理状态恢复最佳(图3)。
根据生存率结果,选择TSA剂量为5.0 mg/kg进行时效实验,分别于12、24、48 h时间点取各组血清进行ELISA检测。血清检测结果显示,12和24 h时DMSO+E.coli组TNF-α和IL-10水平均显著高于DMSO组(P<0.000 1),其中感染后24 h,E.coli+5.0 mg/kg TSA组TNF-α水平明显低于DMSO+E.coli组(P<0.000 1),并且伴随着IL-10水平的显著升高(P<0.05,图4)。基于以上结果,选择感染后24 h时间点进行量效实验,采用2.5、5.0、10.0 mg/kg TSA干预,ELISA检测感染后24 h各组血清炎性因子分泌水平。结果发现,DMSO+E.coli组血清TNF-α显著高于DMSO组和E.coli+TSA组(P<0.000 1);其中5.0 mg/kg TSA干预24 h后血清中TNF-α水平均较2.5、10.0 mg/kg TSA干预低,而血清IL-10水平5.0 mg/kg TSA组明显高于10.0 mg/kg TSA干预(P<0.05,图5)。
根据前述实验结果,以E.coli菌液(3×108 CFU/mL)剂量为200 µL造模,TSA干预浓度为5.0 mg/kg,感染24 h后取DMSO组、DMSO+E.coli组和E.coli+5.0 mg/kg TSA组周围淋巴结和脾组织进行研磨,而后收集细胞,并通过磁珠富集CD4+T细胞进行转录组测序。结果显示,组内相关性好,组间差异显著(图6A~B)。TNF-α和IL-10等基因表达趋势与前期ELISA结果一致,同时KEGG通路富集图可以看出,TSA干预后可以影响调控FoxO、Th17、Th1/2等T细胞分化的信号通路(图6C~D)。
为了进一步检测TSA是否影响了CD4+T细胞各亚群比例的变化,小鼠E.coli感染建模和5.0 mg/kg TSA处理后96 h,取小鼠淋巴结和脾组织的混合细胞进行流式细胞分析。结果显示在CD4+T细胞中E.coli+5.0 mg/kg TSA组TGF-β表达高于DMSO+E.coli组;而IL-17表达低于DMSO+E.coli组(图7),表明CD4+T细胞亚群中可能出现Treg细胞比例增多,而Th17细胞比例降低。
根据前述实验结果,利用RT-qPCR检测5.0 mg/kg TSA处理后各组小鼠E.coli感染12、24、48、96 h后的CD4+T细胞亚群基因表达情况。结果如图8显示,12 h时DMSO+E.coli组Foxp3表达水平高于DMSO组(P<0.000 1),24、48、96 h时均低于DMSO组(P<0.000 1),而12、24、96 h时E.coli+5.0 mg/kg TSA组Foxp3表达水平均高于DMSO+E.coli组(P<0.05),与流式细胞检测结果一致,TSA处理增加了Treg细胞比例。与DMSO组相比,DMSO+E.coli组和E.coli+5.0 mg/kg TSA组的RORγt表达在12、24、48 h均降低,但差异不具有统计学意义;96 h时DMSO+E.coli组和E.coli+5.0 mg/kg TSA组的RORγt表达显著增加(P<0.000 1);但E.coli+5.0 mg/kg TSA组RORγt表达低于DMSO+E.coli组,提示感染引起Th17细胞比例升高,而TSA起到降低Th17细胞比例,发挥调节CD4+T细胞亚群平衡的作用。
本研究围绕全球常见病原菌感染对机体造成的严重后果,以E.coli引发的感染性炎症为例,在前期工作基础上,探讨TSA对E.coli感染小鼠预后的影响,并从免疫学角度阐释其作用机制,可为细菌感染性炎症的治疗策略提供实验依据和新思路。
E.coli是临床上消化系统疾病最常见的致病菌,亚型众多且具有复杂多样的性质,随着临床药物的滥用,其不断从非致病性演变为高致病性,引起严重疾病的爆发[20]。致病性E.coli感染是全球细菌感染发病率和死亡率的重要诱因,其病理核心在于宿主免疫反应的失衡[2-4]。细菌感染会启动机体先天免疫和适应性免疫的应答,经DC抗原递呈作用,使Th0分化为多种CD4+T细胞亚群,如Th1、Th2、Treg、Th17等,通过多种免疫平衡如Treg-Th17、Th1-Th2、Treg-Th1等发挥作用。不同CD4+T细胞亚群发挥的作用各不相同。例如,作为适应性免疫细胞的重要角色之一,Treg在E.coli感染免疫中扮演着复杂的“双刃剑”作用:OKEKE等[21]发现Treg能下调炎症免疫反应并帮助维持免疫平衡,即使在非致命性大肠杆菌感染中,Treg的耗竭也会导致死亡,并伴随血清中促炎细胞因子水平的升高;SHA等[22]发现大肠杆菌 LF82感染可加剧小鼠结肠炎症,破坏肠道黏膜屏障,增加肠道黏膜通透性,并加剧Th17-Treg失衡和肠道菌群紊乱。因此,挖掘调控包括Treg在内的CD4+T细胞亚群功能的关键药物可能是有效治疗E.coli感染的新路径。
TSA相关研究多集中在表观遗传学领域。近年来,越来越多的研究显示,TSA与炎症反应关系密切,而且可能参与了对机体免疫细胞功能的调控。本团队前期工作发现,TSA能够抑制脂多糖(lipopolysaccharides,LPS)刺激淋巴细胞的分泌功能,其机制可能与新型转录因子Musculin(MSC)、IL-17和IL-22的表达变化有关[23]。另有研究发现,TSA能增加Treg数量,阻止Treg向Th17转分化[24-25]。新近研究还发现,TSA具有抗炎抗菌的作用:LI等[26]发现TSA与丁酸盐一样能明显抑制炎症性肠病(inflammatory bowel disease,IBD)中性粒细胞产生促炎细胞因子、趋化因子和钙卫蛋白。
本研究发现,5.0 mg/kg TSA能够显著提高E.coli感染小鼠生存率,有效缓解E.coli感染导致的体质量下降,显著改善小肠肠道病理损伤。这些保护效应与炎症状态的改善直接相关,也与前述文献报道一致。另外,TSA干预(尤其5 mg/kg)在E.coli感染关键期(即感染后24 h)能显著降低血清中的促炎因子TNF-α水平,明显提升抗炎因子IL-10水平。由于IL-10是维持免疫稳态、限制过度炎症的关键因子,主要由Treg等免疫细胞分泌,而Treg是CD4+T细胞的重要亚群之一。该结果提示,TSA的抗炎作用机制有可能与包括Treg在内的CD4+T细胞亚群有关。
作为HDAC抑制剂,TSA可能通过改变染色质构象(如增加Foxp3基因位点的组蛋白乙酰化水平),解除对Foxp3基因的转录抑制,从而促进Foxp3的表达和Treg的功能[13,19]。本研究通过转录组测序和RT-qPCR检测发现,TSA对CD4⁺T细胞分化具有明显调控作用,特别是对Treg的激活。E.coli感染96 h后,5.0 mg/kg TSA干预可显著上调脾组织和周围淋巴结(腹股沟、腋窝、颈部)中Treg关键转录因子Foxp3的mRNA表达水平,并伴随着RORγt(Th17标志转录因子)表达的下调。Foxp3是Treg发育和功能执行的核心调控因子,其表达水平直接决定了Treg的免疫抑制能力[5-7],Th17细胞在介导细菌感染,尤其是肠道炎症中扮演着促炎角色,TSA可能通过抑制Th17的分化,协同Treg的增强,即TSA可能通过调控Treg-Th17平衡促进炎症消退和组织修复。RT-qPCR检测发现,在感染早期即48 h以前,DMSO+E.coli组和E.coli+5.0 mg/kg TSA组Foxp3(除12 h时)和RORγt的表达都明显低于DMSO组,可能由于细菌感染后引起机体内T细胞分化需要时间;在感染时长达96 h时,RORγt在E.coli+5.0 mg/kg TSA组和DMSO+E.coli组的表达均显著高于DMSO组,且E.coli+5.0 mg/kg TSA组表达水平低于DMSO+E.coli组;而96 h时Foxp3在E.coli+5.0 mg/kg TSA组表达高于DMSO+E.coli组;96 h流式细胞检测结果也与RT-qPCR结果趋势一致。这提示在感染中后期,TSA可能是通过调控CD4+ T细胞朝向Treg亚群分化同时抑制其向Th17亚群分化,从而抑制促炎因子释放来缓解细菌感染性炎症疾病。在感染后24 h,E.coli+5.0 mg/kg TSA组小鼠状态明显优于DMSO+E.coli组,可能是由于在感染急性期,TSA还参与调控巨噬细胞、树突状细胞等先天免疫细胞分泌炎性因子所致。
本研究仅完成了小鼠在体实验。体内因素错综复杂,虽然在反映TSA缓解E.coli引发的感染性炎症方面能够得到科学有效结果,但在机制探讨中,未能简化干扰因素,尚无法阐释CD4+T细胞亚群在此过程中的精准作用。因此,在未来的工作中,开展体外实验,尤其是通过体外定向诱导实验来确定CD4+T细胞亚群的动态分化和转分化过程仍是必要的。
细菌感染性疾病的防控始终是全球范围面临的重要卫生课题[27]。本研究发现,5.0 mg/kg TSA能够对E.coli感染小鼠小肠肠道病理起保护作用,抑制炎症反应,修复小肠损伤,改善预后,其机制可能与TSA可调控CD4+T细胞亚群(尤其是Treg-Th17平衡)有关。本研究揭示了TSA在抗菌抗炎方面的新作用,可为其在炎症与免疫领域的机制探讨奠定基础,促进细菌感染性疾病的防治进程。
