Abstract
载体和/或人乳头瘤病毒基因的构建体被用于转化宿主细胞,如细菌,酵母细胞,真菌细胞,昆虫细胞,哺乳动物细胞和植物细胞。在允许至少一种由载体和/或基因构建体编码的蛋白质的蛋白质片段自发装配成诱发免疫原性应答的病毒样颗粒的条件下培养宿主细胞,所述病毒样颗粒针对人乳头瘤病毒。
Description
发明背景
本发明涉及载体和/或构建体,和转基因生物。
在本说明书中下列术语,短语和/或子句应当理解为是指:
“构建体”-如本文所用与术语如“偶联物”,“盒”,和“杂化物”同义,包括直接或间接与启动子连接的核苷酸序列。构建体可包含或表达标记,其允许在宿主细胞中选择构建体。
“表达载体”-如本文所用是指能够体内或体外表达的构建体。
“表达”-应当理解为是指从DNA模板通过转录和翻译生产蛋白质。
“遗传修饰的生物”-如本文所用是指由于以通过交配或自然重组或两者天然不发生的方式作为人为干预的结果已经被导入核苷酸序列的生物。
“在硅片上(In silico)”-本文所述的部分测定和/或方法可以通过使用适当的计算软件进行。如此进行的这些测定和/方法应当理解为被包含其中。
“核苷酸序列”-如本文所用与术语“核苷酸序列”和/或术语“多聚核酸”和/或术语“多核苷酸”同义,并包括基因组DNA,cDNA,重组DNA,合成DNA,和RNA,和上述的任何组合,此外核苷酸序列可以是双链或单链无论表示有义链或反义链。优选地,术语“核苷酸序列”是指DNA。
“可操作性连接”-如本文所用是指并列,其中将与编码序列“可操作性连接”的启动子以这样方式即编码序列的表达是在与控制序列(即尤其启动子,增强子和其它表达调节信号)相适合的条件下实现来连接。
“启动子”-如本文所用是指导核苷酸序列可调型转录的核苷酸序列。
“蛋白质”-如本文所用是用来表示肽和多肽。

乳头瘤病毒(PVs)属于分类科乳头瘤病毒亚科(Papilomaviridae),是小的、无包被的、双链(ds)DNA病毒。这些病毒感染各种各样的高等脊椎动物并且是高度种特异性的。经感染后,人乳头瘤病毒(HPVs)对未分化的鳞状上皮细胞具有特别的向性,除与足底疣,扁平疣,和生殖疣(尖锐湿疣)相关以外。HPV感染还与称为疣状表皮发育不良的疾病有关,该疾病为一种稀见的终生疾病,其特征在于散布的乳头状瘤。此外,已经存在某些乳头瘤病毒分离株与包括子宫颈癌,外阴癌,阴茎癌的泌尿生殖癌,和疣状表皮发育不良损害的恶性转移的流行病学和生物化学联系。在表征的各型HPV中,已经将大约27种鉴定为肛殖感染的病原体。6,11,16,18,31,35和42型HPV已经被鉴定是最普遍的,而16,18,31,33,51和54型已经与肛殖癌有关,被认为是高危,更特别地HPV-16已经在95%子宫颈癌中发现。
直到最近认为高危生殖HPVs仅在性交期间传播,然而研究表明婴儿在出生时从他们母亲获得高危HPV感染。除了非性母婴传播,研究者在来源于妇女的阴道拭子中,在来源于少女的子宫颈-阴道标本中,和在来源于61位声称无性接触历史的妇女中的9位的外阴拭子中检测到HPVDNA。
最初的HPV感染导致颈上皮内肿瘤形成(CIN),更通常已知为癌前病变。已经发现在一些妇女中存在CIN的自发消退,但这并非总是如此,病变可持续多年,增加向子宫颈癌进展的可能性。
从冷冻疗法,外科切除和局部治疗范围的治疗方法经常不减轻问题,对于对治疗应答的患者,复发经常是个问题。最终破坏所有感染组织似乎不可行,因为多病灶疾病和潜伏是感染的常见特征。靶向设计和抑制病毒复制的抗病毒药物似乎在HPV感染的情形中无效,首先因为该病毒不在保持感染的细胞中复制和其次由于病毒复制基因似乎通过整合,重排和缺失而消失的事实。
常规上大多数预防疫苗已由活的减毒病毒或福尔马林灭活的病毒组成。由于涉及产生大量的这些常规疫苗的困难和风险,已经很强调开发病毒蛋白亚单位疫苗和生产其的方法。

本发明优选实施方案详述
制备转基因生物的方法对于本领域的技术人员是已知的,在本说明书中将不深入展开。
克隆和制备农杆菌属克隆
利用HIND III和EcoR I限制位点将HPV-11 L1和HPV-16 L1基因片段单独克隆到原始载体pART7的多克隆位点(MCS)中以提供构建体HPV11 L1 NLS-,HPV 11 L1,HPV 16 L1 NLS-,和HPV 16 L1。
通过Not I消化从pART7载体(图1)中切除完整的盒,并克隆到二元载体pART27(图2)中。
将各个pART27克隆转染到根癌农杆菌菌株C58C1中。
叶盘转化和组织培养
用农杆菌属克隆转化烟草cv Xanthi和Soulouk叶盘,在卡那霉素组织培养基上选择转化体,如Turpen等所述(Transfection of whole plants fromwounds inoculated with Agrobacterium tumefaciens containing cDNA oftobacco mosaic virus.J.Virol.Meth.42:227-240)。
用农杆菌属克隆转化番茄cv Tiny Tom子叶,如Pfitzner所述(Transformation of tomato.J.Mol.Biol.Meth.81:359-363)。
用农杆菌属克隆转化开花拟南芥菜cv Columbia植物,如Clough和Bent所述(在http://www.cropsci.uiuc.edu/~a-bent/protocol.hmtl可获得的简化的拟南芥属转化方案),在卡那霉素组织培养基上选择转化体,如Turpen等所述(Transfection of whole plants from wounds inoculated withAgrobacterium tumefaciens containing cDNA of tobacco mosaic virus.J.Virol.Meth.42:227-240)。
筛选转基因植物
使用Dellaporta等所述方法(A plant DNA minipreparation:Version II.Cold Spring Harbour Laboratory.Cold Spring Harbour)从转化体中提取植物基因组DNA,通过PCR证实整合基因的存在。
从转基因植物中提取VLP
在1∶2体积(植物材料:缓冲液)的缓冲液(对于HPV使用含有0.5MNaCl的PBS)中搅匀植物叶子材料,并在漏斗上压紧通过粗棉布直至浆干燥。在4℃下将提取物离心10分钟(3000rpm)。将10%PEG(MW 8000)加入上清液并让在4℃溶解过夜。然后将这在4℃下3000rpm离心10分钟。在4℃下将沉淀重悬浮在1/10原始体积的PBS(0.5M NaCl)中。然后在3000rpm下将混合物离心15分钟以便去除所有变性的不溶性组分。将提取物覆盖在40%的蔗糖垫(在含有0.5M NaCl的PBS中制备)上,并在100 000xg(对于Sorvall SW28,24 000rpm)下在10℃下离心2.5小时。将沉淀重悬浮在少量PBS(0.5M NaCl)中并将悬浮液通过18 & 26规格的针以降低它的粘度。将该悬浮液加样到10-40%的线性蔗糖梯度上并在10℃下100 000xg(对于SW 28,24 000rpm)旋转3小时。用针和注射器去除在散射光下观察到的条带,并在4℃下对PBS(0.5M NaCl)透析12-24小时。
电子显微镜分析
将VLP捕获于包被多克隆抗体(对于HPV-11 L1特异性的)R399的铜网上,并用2%乙酸双氧铀负染。在200CX电子显微镜下观察网格。
在R0中(第一转基因系)L1基因被稳定地整合到烟草cv Xanthi和Soulouk的基因组中。对于T1代(第一代)的自花传粉转基因植物的L1基因观察到常规的3∶1孟德尔式遗传。另外在转基因拟南芥菜植物的T2(第二代)至T5(第五代)中检测到L1基因。
在电子显微镜下观察到的VLP(用抗体捕获或未捕获)外表上类似于使用杆状病毒昆虫细胞系统的L1基因表达产生的那些。观察到颗粒的直径大小约为50-60nm(拟南芥菜),并在检查烟草蛋白质提取物时观察到部分降解的颗粒。
在转基因植物中乳头瘤病毒基因的表达
在进一步的研究中,制备包含HPV-16 L1基因的转基因系,其现在至少是选择的第二代。另外,用HPV-11 NLS-L1基因转化拟南芥菜和烟草植物。最近还用CRPV L1转化烟草植物。所有这些植物系显示生产VLP,尽管浓度低。包含或缺少NLS序列似乎对于HPV-16 L1 VLP表达几乎没有区别,尽管如果定位到植物细胞核上HPV-11 L1可能有毒性的。通过V5 MAb捕获HPV-16 L1 VLP,如图3所示(条=70nm),显示它们在抗原性上适合于疫苗应用。
在图4(条=70mm)中显示从转基因拟南芥属中分离的HPV-11 VLP。
缺少核定位信号的HPV-11 L1蛋白(NLS-,Δ483)和许多不同的HPV-16 L1和L1 NLS-蛋白构建体已经在转基因植物中表达,已经测定这些制备T=7二十面体的颗粒VLP,经注射后在兔中是免疫原性的,在形态学上似乎与在昆虫细胞的杆状病毒表达系统中制备的VLP相同。另外,已经测定在转基因植物中制备的HPV-16 VLP与构象特异的单克隆抗体(MAb V5)结合,并阻止中和抗体结合。这些发现显示在植物中制备的VLP在功能上与在昆虫细胞中制备的VLP相同。另外,下列构建体已经通过重组杆状病毒在昆虫细胞中表达,其与被未改变的L1蛋白结合的、相同的构象特异和序列特异的Mab结合:
a.缺少10个N-末端密码子的HPV 16 L1基因(ΔN10),其装配成T=1和此外T=7的二十面体颗粒;
b.缺少10个N-末端密码子和NLS的HPV 16 L1基因(ΔN10Δ483),其装配成T=1和此外T=7的二十面体颗粒;
c.在氨基酸428处具有C至G突变(pen)的HPV 16 L1基因(pen504),其装配成五聚体;
d.具有pen和ΔN10修饰的HPV 16 L1基因,其装配成五聚体;
e.具有pen和Δ483修饰的HPV 16 L1基因,其装配成五聚体;和
f.具有pen和ΔN10Δ483修饰的HPV 16 L1基因,其装配成五聚体。
对于本领域技术人员明显的是这些构建体可以在转基因植物中表达并应该以完全相同的方式起作用。
对于本领域技术人员紧接着明显的是尽管本文已经只列举本发明的某些实施方案,本发明的其它修改和/或变体是可能的。这些修改和/或变体应当被认为属于本发明的范围内。
