Abstract
本发明涉一种阳离子脂质体‑鱼精蛋白‑mRNA肿瘤疫苗及其制备方法和应用方法,该肿瘤疫苗是以阳离子脂质体‑鱼精蛋白复合物为 mRNA的递送载体兼佐剂,其中阳离子脂质体:鱼精蛋白:mRNA质量比5:1:1~15:2:1,最佳质量比优选为10:1:1,所构建的阳离子脂质体‑鱼精蛋白‑mRNA肿瘤疫苗的粒径是50~800nm,Zeta电位是10~60mv,包封效率为70%~95%。本发明制备的阳离子脂质体‑鱼精蛋白‑mRNA肿瘤疫苗能够有效促进APCs的抗原摄取,诱导DC刺激、成熟,促进细胞因子分泌,引起抗肿瘤免疫应答。该肿瘤疫苗通过肌内、皮下注射或鼻粘膜给药进行免疫治疗,其中鼻黏膜途径给药,可表现出更为优良的肿瘤治疗效果,在肿瘤治疗方面具有广阔的应用前景。
Description
技术领域
本发明属于纳米材料技术领域及核酸疫苗领域,特别是涉及一种阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗及其制备方法和在肿瘤治疗中的应用。
背景技术
面对癌症等威胁生命的疾病,疫苗接种是目前人类预防和治疗最有效的方法,随着肿瘤免疫疗法的深入研究,治疗性疫苗在治疗癌症以及传染性疾病方面具有巨大的潜力。蛋白、肽和DNA质粒作为传统上疫苗开发的抗原,蛋白、肽类疫苗相对容易制备并且可以大规模生产,但免疫原性弱、引起免疫应答持续时间短,抗原肽选择具有局限性。质粒DNA疫苗免疫效应低且存在不受控制的基因组突变和免疫耐受的风险,存在潜在的安全问题。mRNA 疫苗是在基因治疗基础上发展起来的一种有潜力的疫苗,在肿瘤及其传染病治疗方面具有广阔的应用前景,但mRNA 属于带负电荷的生物大分子,较难透过细胞膜进入细胞发挥作用,mRNA容易被血浆或组织酶降解,且需要佐剂辅助增强免疫应答效应。
脂质体就是一种对疫苗有很强的增效作用的佐剂,脂质体是目前应用最广泛的疫苗佐剂,最有希望成为理想疫苗佐剂的物质之一,由磷脂双分子层构成,结构类似于细胞膜,研究发现脂质体的佐剂功能与它的表面电荷密切相关。一般来说,抗原提呈细胞对正电荷脂质体的吞噬作用要强于负电荷和中性脂质体,阳离子脂质体不仅具有疫苗佐剂功能因表面正电荷能促进细胞摄取、增加抗原提呈、延长刺激细胞免疫, 同时因其具有靶向性、缓释性、低毒性及提高稳定性等特点,也是一种非常理想的疫苗纳米递送载体,因此阳离子脂质体成为一种 mRNA 疫苗的理想佐剂兼递送载体功能。
为了防止脂质体包载抗原过程中容易发生其内包裹 mRNA 抗原的丢失,且体内外容易受核酸酶的作用而影响mRNA 稳定性,需要对阳离子脂质体包载 mRNA 的效率及稳定性不断改善。鱼精蛋白是一种带正电荷无毒,具有生物可降解性的天然碱性蛋白,已被美国FDA 批准用于药用辅料,其抗原性弱,安全性好。已有研究报道富含精氨酸的聚阳离子鱼精蛋白(protamine)可将 mRNA 缩合成纳米大小的复合物,防止核酸酶对mRNA的降解作用,由于阳离子聚合物的加入,能更有效地缩合mRNA,且防止脂质体包裹mRNA过程中出现脂质体融合使其包裹的mRNA丢失,提高 mRNA 递送系统的物理和生物学稳定。
免疫途径是影响疫苗免疫应答效应的关键因素。通常情况下,肿瘤疫苗是通过肌内或皮下注射等传统给药方式进行治疗,鼻腔黏膜免疫是近年来发展的新型免疫途径,相比较传统给药方式不仅能够有效地诱导系统性免疫应答,而且可以诱导局部黏膜免疫。鼻相关淋巴组织(NALT)由滤泡相关的上皮细胞(包括M细胞)和APCs(巨噬细胞和DCs等)、大量B及T淋巴细胞组成。鼻粘膜释放避免肝脏首过效应,能有效诱导系统免疫及黏膜免疫;抗原释放周期长,可在鼻相关淋巴组织及其引流淋巴结保持更长时间的免疫记忆;鼻腔黏膜免疫操作简便,病人依从性高。因此,鼻腔黏膜免疫可成为mRNA疫苗免疫治疗的理想给药途径。
抗原提呈细胞(APCs)指能够摄取且细胞内加工处理抗原,将抗原信息提呈给T淋巴细胞的一类细胞。抗原提呈细胞又称为专职性抗原提呈细胞,包括树突状细胞、巨噬细胞以及B淋巴细胞等。树突状细胞(Dendritic cells, DC)是目前发现功能最强的抗原提呈细胞,能够同时激发初始性和获得性免疫应答。DC在免疫系统中对抗原的摄取、处理及提呈过程扮演重要角色,已成为抗病毒和抗肿瘤免疫反应的中心环节。大多数DC在体内稳态时处于未成熟状态,受到抗原刺激,所述抗原可以是蛋白质,肽和核酸,如质粒DNA或编码抗原的mRNA,能够捕获抗原发育为成熟DC, 迁移至引流淋巴结有效激发抗原特异性细胞和体液免疫应答。因此,对于新型mRNA疫苗经鼻腔黏膜免疫后,DC 捕获抗原后在引流淋巴结的分布,影响疫苗的免疫应答效果。
综上所述,构建一种阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗,探讨其形成条件及理化特性;评价该疫苗递送系统对 DCs 成熟及抗原递呈能力,以及经鼻粘膜免疫后,小鼠体内激发 T 细胞增殖及抗肿瘤效果,探讨其免疫学机制和免疫学效应,具有非常重要的意义。
发明内容
本发明的目的就在于提供一种阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗,从而克服现有传统疫苗存在的免疫原性弱、接种途径单一、病人顺应性差等缺陷,使其通过鼻黏膜免疫后能有效诱免疫应答反应。mRNA疫苗可通过利用肿瘤抗原物质诱导机体特异性免疫反应,杀伤肿瘤细胞,达到治疗肿瘤的目的。
本发明的另一目的是提供阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗的制备方法。
本发明的另一目的是提供上述供阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗的应用方法。
为实现上述发明目的,本发明采用的技术方案如下:
一种阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗,其特征在于,该肿瘤疫苗是以阳离子脂质体-鱼精蛋白复合物为 mRNA的递送载体兼佐剂,其中阳离子脂质体:鱼精蛋白:mRNA质量比5:1:1~15:2:1,最佳质量比优选为10:1:1,所构建的阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗的粒径是50~800nm,Zeta电位是10~60mv,包封效率为70%~95%。
所述阳离子脂质体是由氯化三甲基-2, 3-二油烯氧基丙基铵(DOTMA)、溴化三甲基-2, 3-二油酰氧基丙基铵(DOTAP)、二甲基双十八烷基铵(DDA)、海藻糖二霉菌酸脂合成类似物(TDB)、溴化二甲基双十八烷基铵(DDAB)、二油酰基磷脂酰乙醇胺(DOPE)、胆固醇(Chol)、二硬脂酰基磷脂酰乙醇胺-聚乙二醇2000(DSPE-PEG2000)、溴化三甲基十四烷基铵(TTAB)、溴化三甲基十六烷基铵(CTAB)中的一种或几种组成;优选为溴化三甲基-2, 3-二油酰氧基丙基铵(TTAB)、胆固醇(Chol)和二硬脂酰基磷脂酰乙醇胺-聚乙二醇2000(DSPE-PEG2000)的混合物,其摩尔比为1:1:0.1~1:1:1。

所述鱼精蛋白是一个小分子多肽,分子量较低,由30~50个左右氨基酸组成,是精氨酸富集的强碱性蛋白质,带正电荷、无毒,能防止脂质体包裹抗原过程中所造成其内包裹mRNA 抗原的丢失,提高 mRNA 递送系统的物理和生物学稳定。
上述阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗的制备方法,其特征是:以阳离子脂质体-鱼精蛋白复合物为递送载体兼佐剂,采用薄膜分散法、冻融法或冷冻干燥法将鱼精蛋白缩合的mRNA包载于其中。
本发明以形态、粒径、Zeta电位、包封率等特性为考察指标,对薄膜分散法制备的空白脂质体的主要影响因素:有机溶剂的种类及比例、水化介质的种类及pH、mRNA与脂质体鱼精蛋白复合物的比例、水化时间、水化温度、水化方式、超声时间进行筛选,并对其进行优化,最终得到阳离子脂质体-鱼精蛋白-mRNA疫苗的步骤包括:将阳离子脂质体先溶于有机溶剂中,减压旋转蒸发,用氮气除尽有机溶剂,然后加入水化介质,在50~70℃水浴条件下水化孵育15min~1h,得到空白脂质体;将鱼精蛋白缩合的mRNA加入到上述空白脂质体中,使其充分融合静置20~40min,即得阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗。或者:取适量体积的脂质载体溶液和鱼精蛋白水溶液,将两者混合后稀释,将 mRNA溶液逐滴加入到上述混合溶液中,mRNA浓度范围为10ng/µl~2000ng/µl,使其充分融合静置20~40min,即得阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗。

上述阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗通过肌内或皮下注射或鼻粘膜途径进行免疫治疗,其中鼻黏膜途免疫具有良好的肿瘤治疗效果,尤其是抑制Lewis肺癌肿瘤生长。
所述mRNA释放到细胞质中翻译成功能性蛋白质,加工为抗原肽提呈到细胞表面,促进T细胞刺激成熟, 激活抗肿瘤免疫。
本发明具有以下技术优势:
1)本发明阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗较目前多肽疫苗、重组蛋白疫苗、树突状细胞疫苗、DNA疫苗等有广泛应用前景,mRNA不会插入宿主细胞染色体中不融入基因序列中,无基因插入突变风险,安全性更高;mRNA 合成和纯化快速,简便且成本低。基于以上原因,mRNA 疫苗在肿瘤治疗领域展现了巨大的潜力,已广泛应用于前列腺癌及转移黑色素瘤等肿瘤治疗研究,正在获得更多的关注及发展。肺癌发病率和致死率在男性恶性肿瘤中已居首位,女性中肺癌的发病率也极高,且对目前临床各种治疗手段仍很不理想,尤其是化疗药具有较高的耐受性,限制了其治疗效果。因此,应用 mRNA 肿瘤疫苗治疗肺癌被认为是极具前景的治疗策略。
2)本发明以阳离子脂质体-鱼精蛋白作为疫苗佐剂和载体,尤其是以DOTAP/Chol/DSPE-PEG2000和鱼精蛋白复合物为优选研究对象,将mRNA包载于其中,制得阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗。用琼脂糖凝胶电泳阻滞实验,考察阳离子脂质体-鱼精蛋白与mRNA的相互作用,阳离子脂质体-鱼精蛋白与mRNA质量比例为5:1:1~15:2:1, 其中,阳离子脂质体-鱼精蛋白-mRNA最佳质量比优选为10:1:1。见图1。此外,用增强型绿色荧光蛋白(EGFP)为报告基因,利用激光共聚焦显微镜成像,并结合流式细胞术测定阳性细胞率及平均荧光强度,考察小鼠骨髓来源树突状细胞对不同纳米疫苗体外的摄取情况,表明阳离子脂质体-鱼精蛋白复合物可以成功将mRNA递送到BMDCs中,翻译成具有功能性的蛋白质,进而被DCs加工提呈给T细胞, 激活适应性免疫。见图3。
3)本发明以制得DOTAP/Chol/DSPE-PEG2000-鱼精蛋白-mRNA肿瘤疫苗体外的树突状细胞刺激成熟实验结果显示:DOTAP/Chol/DSPE-PEG2000脂质体鱼精蛋白mRNA疫苗能显著上调树突状细胞表面共刺激分子CD86和MHC-II的表达水平,表明DOTAP/Chol/DSPE-PEG2000脂质体鱼精蛋白mRNA疫苗能够有效促进小鼠骨髓未成熟树突状细胞的分化成熟,且检测到体外细胞因子IL-12、TNF-α、IL-6、IFN-β、IFN-γ等分泌从而表明DOTAP/Chol/DSPE-PEG2000脂质体-鱼精蛋白是一种良好的疫苗佐剂和递送系统。见图3、见图4。
4)本发明采用鼻黏膜途径给药,通常情况下,肿瘤疫苗是通过肌内或皮下注射进行治疗,限制纳米粒子的迁移,只有少部分负载抗原的纳米粒子递送到淋巴结,诱导的抗原特异性免疫应答较弱,鼻黏膜途径给药克服了现用接种途径单一,病人顺应性差等问题。动物实验结果显示,该阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗经小鼠鼻黏膜免疫后,鼻腔黏膜免疫抗原可以很快到 NALT,该淋巴组织富含滤泡相关上皮细胞(包括M 细胞)、DCs 和大量的 B 及 T 淋巴细胞,可诱导较强的肿瘤免疫杀伤效果。表明该阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗可显著提高小鼠细胞免疫应答水平;同时,表明鼻黏膜免疫是一种理想的肿瘤疫苗免疫给药途径。见图5、见图6。
综上所述,本发明制备的阳离子脂质体-鱼精蛋白-mRNA肿瘤疫苗,可作为肿瘤免疫治疗的新型肿瘤疫苗,能够刺激体外DC细胞成熟,分泌细胞因子,且稳定性较好,经小鼠鼻黏膜免疫后,该新型mRNA肿瘤疫苗能显著提高小鼠细胞免疫应答水平从而引起抗肿瘤免疫效果。
