Description
技术领域
本发明一般涉及疫苗,更具体而言涉及禽流感疫苗。
背景技术
禽流感是一种家禽的主要疾病。该疾病是由禽流感病毒(avian influenzavirus,AIV)所引起的。高致病性禽流感病毒如H5N1和H5N2病毒株造成数亿鸟类,包括家禽的死亡。目前针对高致病性禽流感病毒(highly pathogenic avian influenza virus,HPAIV)的市售疫苗是由灭活病毒所制成。这种疫苗可能对新突变的高致病性病毒株无效。此外,以灭活病毒疫苗接种的鸟类所产生的抗体无法与被感染的鸟类区分,这可能导致难以监测该疾病流行的情况。因此,需要开发针对禽流感病毒(AIV)的新颖且有效的疫苗,以控制高致病性禽流感病毒(HPAIV)的疫情扩散。针对这些问题,亚单位疫苗相对于全病毒疫苗而言是较佳的设计。表现全病毒的结构以及抗原组成的类病毒颗粒(Virus-likeparticle,VLP)是一种有效的疫苗抗原,而且没有病毒生长的风险。
发明内容
一方面,本发明涉及一种疫苗组合物,包含:
(a)有效剂量的流感病毒类病毒颗粒(virus-like particle,VLP),包含:
(i)流感病毒M1蛋白、流感病毒M2蛋白、流感病毒血凝素(hemagglutinin,HA),以及流感病毒神经氨酸酶(neuraminidase,NA)蛋白;
(b)口蹄疫病毒(Foot-and-mouth disease virus,FMDV)的重组VP3壳蛋白(rVP3);以及
(c)铝胶。
另一方面,本发明涉及一种疫苗组合物,其包含:
(a)有效剂量的流感类病毒颗粒(VLP),包含:
(i)流感病毒M1蛋白、流感病毒M2蛋白、流感病毒血凝素(HA),以及流感病毒神经氨酸酶(NA)蛋白;
(b)口蹄疫病毒(FMDV)VP3壳蛋白、口蹄疫病毒重组VP3壳蛋白(rVP3)、VP3壳蛋白肽或SUMO VP3壳蛋白;以及
(c)铝胶。
在本发明的一个具体实施例中,该流感病毒血凝素(HA)和该流感病毒神经氨酸酶(NA)蛋白为禽流感病毒血凝素(HA)和禽流感病毒神经氨酸酶(NA)蛋白。
在另一具体实施例中,该禽流感病毒血凝素(HA)和该禽流感病毒神经氨酸酶(NA)蛋白选自由H5N2、H5N1以及H5N8所组成的群组。
另一方面,本发明涉及配制本发明的疫苗组合物的方法,其中该方法包括将该有效剂量的流感病毒类病毒颗粒(VLP)加入该VP3壳蛋白、rVP3壳蛋白、VP3壳蛋白肽或SUMOVP3壳蛋白,以及铝胶中。
另外,再一方面,本发明还涉及本发明的疫苗组合物在制备用于在有此需要的受试者中诱导免疫原性反应的药物中的用途。
本发明还涉及一种疫苗组合物,用于在有此需要的受试者中诱导免疫原性反应。或者,本发明涉及在有此需要的受试者中诱导免疫原性反应的方法,包含对有此需要的受试者施用本发明的疫苗组合物以诱导免疫原性反应。
该受试者可以是哺乳类动物以及禽类动物的至少一种。
另外,又一方面,本发明涉及包含流感病毒M1蛋白、流感病毒M2蛋白、流感病毒血凝素(HA),以及流感神经氨酸酶(NA)蛋白的流感病毒类病毒颗粒(VLP)。
或者,本发明涉及流感类病毒颗粒(VLP),其包含:
(a)可以自我组装成VLP核心的流感病毒M1核心蛋白;以及
(b)在该VLP表面上表达的流感病毒血凝素(HA)和流感病毒神经氨酸酶(NA)蛋白;
其中该VLP为非复制性且非感染性的,而且不含有完整的病毒核酸。该流感VLP可以进一步包含在该流感VLP的表面上表达的流感病毒M2蛋白。
另外,另一方面,本发明涉及包含生产本发明的流感病毒VLP的宿主细胞。
在一个具体实施例中,该宿主细胞为Vero细胞或293T细胞。
依照以下说明结合附图将对具体实施例作更好的描述,在不脱离本发明的新颖概念的精神和范围的情况下,明显地可以在其中采取一些变化和修改。
附图说明了本发明的一个或多个具体实施例,并且与书面描述一起用于解释本发明的原理。尽可能地,在整个附图中使用相同的组件符号以指示具体实施例中的相同或相似的组件。

实施例1
自Vero细胞进行流感病毒类病毒颗粒(VLPs)的表达及纯化。根据美国专利号8,980,281建立产生流感病毒VLP的Vero细胞系统。
基于美国专利号8,980,281中公开的已建立的平台,通过将pCI6/TO-M1-M2和pCI4/TO-HA-NA质粒分两步骤稳定转染到293T细胞中,我们成功地产生了生产H5N2-VLP的细胞克隆株。我们还使用Vero E6细胞在Vero细胞中生产流感病毒H5N2-VLP。简言之,我们构建了含有两个表达盒的质粒,用四环霉素诱导方式表达禽流感病毒的H5蛋白和N2蛋白。通过在起始细胞株中稳定转染表达质粒,随后分离克隆株,我们筛选并鉴定了产生H5N2-VLP的细胞株。在微载体悬浮培养系统以脱氧羟四环素诱导,以使VLP由生产细胞表达和分泌。将条件培养基用超高速离心纯化后,对分泌VLP的颗粒形态(图1C)、平均大小和血凝反应能力进行特征分析,并且通过总蛋白量和血凝素(HA)蛋白量来定量VLP成分。我们发现,以这种方式进行的Vero细胞比293T细胞成为更好的VLP生产者。它们含有更多的血凝素(HA)蛋白,且可多达9%的总VLP蛋白(图1A和B)。此外,Vero E6细胞产生的VLP的血球凝集作用效价比293T细胞产生的血球凝集作用效价高4倍。因此,将在Vero E6细胞中产生的H5N2-VLP作为禽流感病毒疫苗的抗原。
抗原制剂和佐剂都是疫苗的重要组分。为了寻找更好的佐剂,我们克隆了口蹄疫病毒壳蛋白的VP3基因。含有VP3基因的质粒在大肠杆菌中过度表达、纯化并重折叠以具有佐剂活性。然后我们研究了rVP3是否可以活化鸡免疫细胞中的免疫反应。我们发现rVP3刺激了鸡的B细胞和CD8+T细胞的增殖(图2A)。rVP3也诱导这些鸡免疫细胞产生IFN-γ(图2B)。这些结果显示,rVP3在体外诱导鸡免疫细胞的细胞免疫反应。
为了检查H5N2-VLP和rVP3的疫苗功效,我们首先以H5N2-VLP单独免疫鸡,发现它没有引起足够的抗体效价,表示H5N2-VLP需要佐剂的辅助以诱导完全免疫反应。与以含有rVP3和铝胶作为佐剂的相同剂量的H5N2-VLP疫苗免疫的鸡,或与以含有铝胶的相同剂量的灭活病毒疫苗免疫的鸡相比,以含有铝胶作为佐剂的低剂量的H5N2-VLP疫苗免疫的鸡在攻毒后10天病情较为严重。以含有rVP3和铝胶作为佐剂的较高剂量的H5N2-VLP疫苗初次免疫并加强免疫的鸡,会引起较高的血球凝集抑制作用(hemagglutination inhibition,HI)抗体以及血清中和(serum neutralization,SN)抗体效价,这与以含有rVP3和铝胶作为佐剂的灭活病毒疫苗免疫的作用及抗体效价类似。此外,以含有rVP3和铝胶作为佐剂的H5N2-VLP疫苗免疫的鸡,经过H5N2病毒攻毒后完全存活(图3A),具有较少的病毒释出,甚至优于以含有rVP3和铝胶作为佐剂的灭活病毒疫苗免疫的结果(图3B)。与我们的鸡免疫细胞体外研究结果一致,以含有rVP3和铝胶作为佐剂的H5N2-VLP疫苗免疫的鸡,诱导产生的IFN-γ和IL18高于以含有rVP3和铝胶作为佐剂的灭活病毒疫苗所诱导产生的IFN-γ和IL18(图3C)。
实施例2
使用如上述类似方法,通过将pCI6/TO-M1-M2和pCI4/TO-HA-NA质粒分两步骤连续稳定地转染到293T细胞中,我们制造出产生H5N1-VLP的细胞克隆株。我们还使用Vero E6细胞在Vero细胞中产生流感病毒H5N1-VLP。简言之,我们构建了含有两个表达盒的质粒,以允许四环霉素诱导表达禽流感病毒的H5蛋白和N1蛋白。通过在生成细胞株中稳定转染表达质粒,随后分离克隆株,我们筛选并鉴定了产生H5N1-VLP的细胞株。在微载体悬浮培养系统中以脱氧羟四环素诱导,以使VLP由生产细胞表达和分泌。在条件培养基的离心纯化后,对分泌VLPs的颗粒形态、平均大小和血凝反应能力进行特征分析,并且通过总蛋白量定量VLP成分。以在Vero E6细胞中产生的H5N1-VLP作为禽流感病毒疫苗的抗原。
实施例3
使用如上述类似方法,通过将pCI6/TO-M1-M2和pCI4/TO-HA-NA质粒分两步骤连续稳定地转染到293T细胞中,我们制造出产生H5N8-VLP的细胞克隆株。我们还使用Vero E6细胞在Vero细胞中产生流感病毒H5N8-VLP。简言之,我们构建了含有两个表达盒的质粒,用四环霉素诱导方式表达禽流感病毒的H5蛋白和N8蛋白。通过在生成细胞株中稳定转染表达质粒,随后分离克隆株,我们筛选并鉴定了产生H5N8-VLP的细胞株。在微载体悬浮培养系统中以脱氧羟四环素诱导,以使VLP由生产细胞表达和分泌。将条件培养基利用超高速离心纯化后,对分泌VLPs的颗粒形态、平均大小和血凝反应能力进行特征分析,并且通过总蛋白量定量VLP成分。以在Vero E6细胞中产生的H5N8-VLP作为禽流感病毒疫苗的抗原。
总之,我们已经发现了针对高致病性禽流感病毒的新疫苗。这种新的禽流感病毒疫苗由禽流感病毒类病毒颗粒(VLP)作为抗原以及以rVP3和铝胶作为佐剂所组成。该疫苗可以在免疫的鸡中诱导高效价的中和抗体以及细胞调节的免疫反应。它保护鸡抵抗高致病性禽类病毒的攻毒以及具有较少的病毒释出。该疫苗可作为抗禽流感病毒的疫苗,以保护家禽产业、家禽蛋产业,以及人类免于禽流感病毒流行病疫情的爆发。
