Abstract
本发明属于生物医药技术领域,公开了一种他米巴罗汀在制备免疫佐剂中的应用,可以诱导产生高效的黏膜免疫应答。
Description
技术领域
本发明属于生物制药领域,涉及他米巴汀的新用途,尤其涉及他米巴汀在制备免疫佐剂中的应用。
背景技术
2005年日本新药株式会社研发出他米巴罗汀(Tamibarotene,Tm),是一种视黄酸受体α/β(RARα/β)激动剂,被FDA批准用于治疗复发或难治性急性前骨髓细胞性白血病(Acute promyelocytic leukemia,APL)。另外,研究表明Tm具有将促肿瘤相关成纤维细胞(Cancer associated fibroblasts,CAF)重编程为抑制性肿瘤相关成纤维细胞,在胰腺癌小鼠模型中,口服Tm可导致α-SMA表达降低,CAF中Meflin表达增加,因此Tm常用于治疗IIIB期非小细胞肺癌伴胸腔积液以及IV期非小细胞肺癌和胰腺癌,其相关治疗目前处于临床前II期试验阶段(Mizutani Y,Iida T,Ohno E,Ishikawa T,Kinoshita F,Kuwatsuka Y,ImaiM,Shimizu S,Tsuruta T,Enomoto A,Kawashima H,Fujishiro M.Safety and efficacyof MIKE-1in patients with advanced pancreatic cancer:a study protocol for anopen-label phase I/II investigator-initiated clinical trial based on a drugrepositioning approach that reprograms the tumour stroma.BMC Cancer.2022,22(1):205)。除此之外,Tm还参与阿尔兹海默症(Alzheimer's disease,AD)病因和病理学等多个靶基因的转录控制,减少不溶性β-淀粉样蛋白的沉积,改善皮质乙酰胆碱的减少,以及减少小鼠行为测试中的焦虑和睡眠不足,还对东莨菪碱诱导的记忆缺陷模型的记忆力有显著改善,因此Tm也可作为治疗阿尔茨海默症的候选药,目前处于临床前II期试验阶段(Fukasawa H,Nakagomi M,Yamagata N,Katsuki H,Kawahara K,Kitaoka K,Miki T,ShudoK.Tamibarotene:a candidate retinoid drug for Alzheimer's disease.Biol PharmBull.2012,35(8):1206-12)。
幽门螺杆菌(Helicobacter pylori,Hp)是一种微需氧,寄生于胃黏膜表面的革兰阴性致病菌,Hp感染首先引起慢性胃炎,并导致胃溃疡和胃萎缩严重者则发展为胃癌。目前全球约50%的人感染Hp,目前主要治疗方法为铋剂四联疗法,但是随着抗生素耐药性的增加,临床上幽门螺杆菌的治疗效果以及复发率不容乐观。现有常见的疫苗候选抗原如尿素酶UreA或UreB、空泡毒素VacA等已表现出不同程度的免疫原性,但是如何筛选出能诱导机体产生黏膜免疫应答的佐剂,一直是幽门螺杆菌疫苗开发的重要问题。
尚未有研究报道他米巴罗汀可作为免疫药物,诱导黏膜免疫应答。
发明内容
本发明目的旨在针对上述现有技术中存在的不足,提供一种他米巴罗汀在制备免疫佐剂中的应用,可高效诱导黏膜免疫应答。
本发明提供的他米巴罗汀在制备免疫佐剂中的应用,以他米巴罗汀和铝佐剂作为复合免疫佐剂。所述他米巴罗汀与铝佐剂的质量比为1:5~100。所述铝佐剂优选为氢氧化铝或磷酸铝。
本发明提供的他米巴罗汀在制备免疫佐剂中的应用,对免疫佐剂的剂型和制备方法没有特别限制,可采用本领域常规通用的制备方法制成片剂、胶囊、颗粒剂、缓释剂、注射剂等各种剂型。
本发明进一步提供了包含以他米巴罗汀为免疫佐剂的药物。该药物包含由他米巴罗汀和氢氧化铝构成的复合免疫佐剂,以及幽门螺杆菌重组蛋白。所述幽门螺杆菌重组蛋白与复合免疫佐剂的质量比为1:5~50。
进一步的,所述幽门螺杆菌重组蛋白为幽门螺杆菌重组蛋白HpaA、幽门螺杆菌重组蛋白SecG、幽门螺杆菌重组蛋白TonB、幽门螺杆菌重组蛋白NC-1、幽门螺杆菌重组蛋白UreA或幽门螺杆菌重组蛋白TatB。在优选实现方式中,所述幽门螺杆菌重组蛋白为幽门螺杆菌重组蛋白HpaA。所述幽门螺杆菌重组蛋白HpaA的氨基酸序列如SEQ ID NO.1所示。
本发明经研究发现,他米巴罗汀用DMSO溶解后与氢氧化铝作为复合免疫佐剂,与幽门螺杆菌重组蛋白HpaA共同肌注免疫小鼠,通过Elisa检测免疫小鼠阴道灌洗液中特异性sIgA的抗体水平。结合动物实验发现抗原HpaA仅与氢氧化铝佐剂免疫小鼠,没有检测到特异性sIgA抗体水平,表明没有诱导黏膜免疫应答;而抗原HpaA与他米巴罗汀和氢氧化铝联合肌注免疫小鼠其阴道灌洗液中特异性sIgA抗体最高效价可达1:32,免疫后5天阳转率为90%,表明他米巴罗汀用作免疫佐剂可高效诱导机体产生黏膜免疫应答。此外抗原HpaA与他米巴罗汀和氢氧化铝联合肌注免疫小鼠其血清IgG效价也高于仅与氢氧化铝免疫小鼠,表明他米巴罗汀用作免疫佐剂也可诱导一定程度的体液免疫应答。
与现有技术相比,本发明他米巴罗汀在制备免疫佐剂中的应用,具有以下有益效果:
(1)本发明对已知的他米巴罗汀发掘了新的医疗用途,开拓了一个新的应用领域,可以作为诱导黏膜免疫应答的佐剂。
(2)本发明提供的他米巴罗汀与氢氧化铝一起构成复合免疫佐剂,可以诱导产生高效的黏膜免疫应答。
(3)本发明提供的他米巴罗汀与氢氧化铝一起构成复合免疫佐剂,还可进一步提高其特异性血清IgG抗体水平,诱导体液免疫应答,扩展他米巴罗汀的应用领域。

应用例
1.幽门螺杆菌重组蛋白HpaA的表达与纯化鉴定
本例中提供的幽门螺杆菌重组抗原蛋白HpaA,通过以下步骤制备获得:
S1、HpaA基因的克隆构建
a、通过NCBI序列比对发现幽门螺杆菌不同菌株间HpaA氨基酸序列高度保守且氨基酸序列如SEQ ID NO:1所示,根据HpaA的氨基酸序列,对其核苷酸序列进行大肠杆菌偏嗜性密码子优化,获得序列如SEQ ID NO:2所示的目的基因片段(下划线示酶切位点碱基序列,双下划线示组氨酸标签序列)。
b、对上述目的基因进行全基因合成,设计通过Nco I和Xho I的酶切位点连接到表达载体pET28a(+)上构建重组表达质粒并转化至重组克隆菌株Escherichia coli Top 10。从重组HpaA-pET28a(+)-E.coli Top 10菌株中提取重组质粒,并对获得的质粒进行测序比对,结果完全一致,经分析确认无氨基酸突变。
c、将重组质粒转化表达菌株E.coli BL21(DE3),获得可以表达HpaA的重组大肠杆菌HpaA-pET28a(+)-E.coli BL21(DE3)。

S2、HpaA蛋白的诱导表达
a、重组菌株进行平板划线复苏培养过夜,将HpaA-pET28a(+)-E.coli BL21(DE3)平板单菌落接种10mL卡那霉素抗性的LB培养基,220rpm 37℃过夜培养,再将过夜培养的HpaA-pET28a(+)-E.coli BL21(DE3)1mL接种至20mL卡那霉素抗性的TB培养基中,220rpm、37℃培养2h,至OD600为0.6时,加入1M IPTG 3mL,使其IPTG终浓度为0.5mM,恒温摇床中220rpm、37℃诱导表达4h。
b、将诱导表达后的菌液用冷冻落地式离心机4℃8000g离心20min,弃去上清,取0.5g沉淀菌体加入破菌液(50mM PB,0.5M NaCl,pH 8.0)混匀,冰浴超声裂解10min(超声3s停止3s),4℃、12000g离心3min,分离上清及沉淀。
c、上述破菌沉淀加入4mL破菌液重悬沉淀,分别取裂菌液、上清、重悬沉淀各40μL加入10μL5×蛋白上样缓冲液(生工,货号:C508320-0010,100℃)金属浴加热10min。
d、将处理好的裂菌液、上清和沉淀分别取10μL作为样品上样,进行12%的SDS-PAGE电泳,经考马斯亮蓝染色后,通过凝胶扫描成像系统(BIO-RAD,ChemiDocTM MP ImagingSystem)扫描成像。灰度分析结果表明,HpaA在HpaA-pET28a(+)-E.coli BL21(DE3)菌株中呈可溶性表达,表达量占总蛋白32%(如图1所示)。
S3、HpaA抗原的纯化制备
a、菌株放大培养:取过夜培养的HpaA-pET28a(+)-E.coli BL21(DE3)菌液60mL加入6L卡那霉素抗性的TB培养基中,220rpm、37℃培养2h,培养至OD600为0.6时,加入1MIPTG3mL,使其IPTG终浓度为0.5mM,恒温摇床中220rpm、37℃诱导表达4h。诱导后的菌液,用冷冻落地式离心机4℃8000g离心20min收集菌体,再加入500mL破菌液(50mM PB,0.5M NaCl,pH8.0)重悬菌体后,将菌液进行高压均质仪破菌,冷冻落地式离心机4℃12000g离心30min收集上清。
b、镍柱亲和层析:破菌上清液抽滤瓶过0.45μm滤膜抽滤备用。纯化仪上使用缓冲液1(50mM PB,500mM NaCl,pH 8.0)平衡镍柱,取过滤后上清液上样,使用缓冲液2(50mMPB,150mM NaCl,pH 8.0)平衡层析柱;使用缓冲液3(50mM PB,150mM NaCl,25mM咪唑,pH8.0)洗脱杂质,使用缓冲液4(50mM PB,150mM NaCl,100mM咪唑,pH 8.0)洗脱目的蛋白,收集A280指示的蛋白洗脱峰。
c、阴离子亲和层析:使用缓冲液5(20mM PB,pH 8.0)平衡阳离子柱;将从镍离子亲和柱的洗脱下的洗脱液使用缓冲液5稀释10倍后进行上样;使用缓冲液5复平衡阴离子柱;使用缓冲液6(20mM PB,100mM NaCl,pH8.0)洗脱杂质蛋白;使用缓冲液7(20mM PB,200mMNaCl,pH 8.0)洗脱目的蛋白,收集A280指示的蛋白洗脱峰,得到幽门螺杆菌重组抗原蛋白HpaA,该重组抗原蛋白HpaA的氨基酸序列如SEQ ID NO:1所示。经12%SDS-page灰度分析检测蛋白纯度,BCA法进行浓度测定后-80℃保存备用。纯化电泳结果如图2所示,泳道1为纯化后蛋白,经12%SDS-PAGE检测,洗脱液呈单一目标蛋白条带,分子质量约为27.2kDa,获得的纯化蛋白纯度为99.2%。
