Description
技术领域
本发明涉及一种重组嵌合蛋白,尤其是一种以轮状病毒VP6蛋白为载体携带乙肝病毒抗原表位的重组嵌合蛋白及其制备,属于医学生物技术领域。
背景技术
轮状病毒(Rotavirus,简称RV)是婴幼儿腹泻的主要病原体。世界范围内每年大约有60多万例RV感染患者死亡,其中80%发生在发展中国家。RV属呼肠病毒科(Reoviridae),轮状病毒属(Rotavirus)。RV基因组由11个片段的双链RNA组成,分别编码6个结构蛋白(VP1-VP4, VP6和VP7)和6个非结构蛋白(NSP1-NSP5/NSP6)。
根据RV组(亚组)抗原蛋白VP6的抗原性的不同,可将至今已发现的轮状病毒RV分为A~G 七个组, A组是婴幼儿腹泻的主要病原体。根据病毒蛋白编码框(ORF)核苷酸序列同源性差异,可将A组轮状病毒RV 的12个蛋白(基因)分为不同的基因型。根据RV基因型分类标准,A组轮状病毒RV的结构蛋白VP6至少可分为16个基因型(I1-I16型)。VP6蛋白由第6基因片段编码,含397个氨基酸,分子量约为44.8KDa。VP6蛋白是轮状病毒RV中含量最丰富的蛋白,约占病毒总蛋白量的51%。 RV内壳中间层由260个致密的VP6蛋白三聚体共780个蛋白分子构成。
VP6蛋白具有重要的生物学功能,是病毒基因组转录和病毒组装不可缺少的成分。VP6蛋白也具有重要的免疫学性质。近年进行的VP6蛋白免疫学研究表明,一些抗VP6蛋白的IgA单克隆抗体诸如7D9所产生的IgA具有保护作用,在SCID鼠中可清除其慢性RV病毒感染。一些研究表明VP6蛋白的抗病毒作用可能是通过IgA的分泌途径而阻碍了病毒的复制循环过程,或作为一种黏膜的分泌型IgA,将RV感染的上皮细胞排除,从而起到保护作用。研究发现VP6蛋白分子中至少存在两个Th细胞抗原表位和一个交叉反应的细胞毒性T淋巴细胞(CTL)表位 。有研究表明在使用麦芽糖结合VP6蛋白对小鼠进行黏膜免疫后,IFN-γ被认为是CD4+T细胞分泌的唯一有效的抗RV的细胞因子。众多的实验表明,经VP6蛋白免疫后,在动物体内确实能引起抗RV感染的作用。抗VP6蛋白单克隆抗体具有抑制病毒转录活性和保护小鼠免受病毒感染的作用。用重组表达的VP6蛋白免疫小鼠,也可诱导小鼠产生免疫保护作用。
VP6蛋白可自我组装成病毒样颗粒(VLPs)。由于VLPs没有感染性,在研究细胞相互作用,开发诊断制剂和疫苗方面,具有更好的安全性。与单一分子的重组抗原相比,VLPs具有更好的免疫原性,可刺激机体产生体液和细胞免疫反应。由于VLPs具有高密度的呈递抗原表位,可产生很强的免疫反应,是许多疫苗研制中很有前景的材料。
至今所有已用于人体的轮状病毒RV疫苗都是减毒活疫苗。1997年始用于人体的多价减毒重组活疫苗Rotashield因后来发现与肠套叠有关联而在使用一年后即停止使用。2006年和2008年分别获准在人群中使用的5价重组减毒活疫苗RotaTeq和单价重组减毒活疫苗Rotarix现也已发现有猪环状病毒DNA污染。Rotarix已在美国人群中停止使用,RotaTeq在人群中尚可正常使用。由于上述用于人类的RV疫苗存在肠套叠和其他病毒核酸污染等风险,且都存在只能降低RV感染引起的死亡率和重症腹泻,不能完全保护RV感染的不足,在Rotarix停用后,RV感染率似有所提高。
乙肝病毒(Heptatitis B Virus,简称HBV)属嗜肝DNA病毒科(Hepadnaviridae),是引起人类急慢性肝炎、肝硬化及肝癌的重要病原。我国现有慢性HBV感染者9300万人。至今已有的能够有效治疗乙肝的药物都存在副作用大的问题,因此,疫苗免疫仍然是主要的控制措施。乙肝难于治疗和预防的重要原因,是因为HBV基因组结构复杂,变异很大。根据HBV基因核苷酸(氨基酸)序列同源性差异,至今发现的HBV株至少可以分为10个基因型(基因型A-J)和数十个基因亚型。因此对HBV蛋白免疫学性质进行深入研究,改进疫苗免疫保护效果,仍有重要的理论意义和使用价值。研制重组抗原表位亚单位疫苗是一个重要的方向。
HBV抗原表位在表面抗原蛋白PreS1,PreS2,S及核心蛋白C上均有分布,在尚无理想的治疗RV和HBV感染药物,以及RV和HBV疫苗尚不十分理想的今天,选择和鉴定这些蛋白上的抗原表位,研制更加安全有效的RV和HBV疫苗,特别是研制可同时保护RV/HBV感染的联合疫苗具有重要的经济和社会价值。
