编码SARS-CoV-2病毒刺突蛋白的核酸及其的应用的制作方法

本发明涉及生物医药技术领域,尤其涉及编码sars-cov-2病毒刺突蛋白的核酸及其的应用。



背景技术:

新型冠状病毒肺炎是一种急性感染性肺炎,2020年2月11日,世界卫生组织(who)将其英文名称定为coronavirusdisease2019(covid-19)。sars-cov-2病毒的核衣壳有核衣壳蛋白(nucleocapsidprotein,n)包裹单股正链rna形成,外有包膜,嵌有三种糖蛋白,刺突蛋白(spikeprotein,s)、包膜蛋白(envelopeprotein,e)和膜蛋白(membraneprotein,m)。其中,e蛋白和m蛋白主要参与病毒的装配过程,s蛋白主要通过与宿主细胞受体结合介导病毒的入侵,并决定病毒组织或宿主嗜性。

目前,仍缺乏针对新冠肺炎病原体的有效抗病毒药物,以隔离治疗、对症支持治疗为主。疫苗是防控传染病最有效的手段。目前在研的covid-19疫苗种类主要有灭活疫苗、减毒活疫苗、核酸疫苗(dna疫苗和mrna疫苗)、蛋白亚单位疫苗及病毒载体疫苗。其中mrna疫苗具有安全、有效、研发周期短等特点,在应对大规模流行病时更具有优势。

近年来moderna和biontech公司开发的mrna(信使核糖核酸)疫苗启动临床试验,提供了mrna疫苗的安全性和有效性的前期数据。目前,mrna研发的关键技术的研究主要集中在:①提高mrna稳定性及翻译效率,②调节免疫原性,③开发高效无毒的递送载体。mrna的组成包括5’帽子结构(cap)、5'utr区、编码抗原蛋白的开放阅读框(openreadingframe,orf),3'utr区和3'poly(a)尾结构。mrna的合成一般是以含靶蛋白orf的质粒dna为模板,经体外转录合成,最后再加上5'cap和3'poly(a)尾。通过对dna模板上的utr区、poly(a)尾和体外转录时的cap,ntp等合成mrna的元件进行设计,可提高mrna的稳定性和翻译效率。此外,可利用分离和纯化技术来优化mrna。本领域认为,mrna的翻译效率与orf序列密切相关,因此,对编码刺突蛋白的核酸序列进行密码子优化是疫苗研发成功的关键。

8.mrna-spike免疫小鼠诱导的抗spike抗体滴度检测

6~8周龄的balb/c雌鼠适应性喂养3天后,3只为对照组注射pbs,5只为0.5μg组,分别肌肉免疫未经过密码子优化后mrna-spike的疫苗,注射0.5μg剂量。35天后,再加强注射0.5μg剂量。70天后,取血检测针对spike抗体滴度。

或者6~8周龄的balb/c雌鼠适应性喂养3天后,2只为对照组注射pbs,4只为0.2μg组,2只为0.5μg组,5只为1μg组,分别肌肉免疫经过密码子优化后mrna-spike的疫苗,注射0.2μg,0.5μg和1μg剂量。35天后,再加强注射0.2μg,0.5μg和1μg剂量。70天后,取血检测针对spike抗体滴度。

抗体滴度检测方法为elisa具体操作如下,96孔酶标板每孔包被50ngspikerbd结构域蛋白室温过夜,第二天用pbst清洗3遍,用5%牛奶封闭,37度1小时后,pbst清洗3遍,加入对应稀释比例的小鼠血清,37℃1小时后,pbst清洗3遍,加入抗小鼠igg重链轻链hrp,37℃1小时后,pbst清洗3遍,最后加入显色液显色。如图4a所示;为未经过密码子的mrna-spike疫苗免疫小鼠后,血清中抗spike抗体滴度,如图4b所示;为经过密码子优化后mrna-spike疫苗免疫小鼠后,血清中抗spike抗体滴度。对比可知经密码子优化后的mrna-spike疫苗,免疫小鼠后产生的抗体滴度更高,效果更好。

以上仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。
