Description
本申请为申请号为2017113093652、申请日为2017年12月11日、发明名称“NK细胞外泌体及相关miRNA在抗菌和抗肿瘤中的应用”的分案申请。
技术领域
本发明涉及通过经跨膜IL-21激活的NK细胞(aNK)分泌的外泌体(exosome),以及相关的miRNA在抗菌中和抗肿瘤的应用。
背景技术
外泌体是一类由细胞分泌的携带胞质组分的纳米级别的膜性小泡,由机体的多种细胞分泌,广泛分布于唾液、血浆、乳汁等体液中。外泌体中含有蛋白质、mRNA和miRNA等多种生物活性物质。外泌体以膜融合的方式将miRNA和蛋白质传递给其他细胞,作为细胞之间相互交流的桥梁。
NK细胞是固有免疫系统中主要的效应细胞,已应用于肿瘤的治疗,其通过释放穿孔素和颗粒酶杀伤被感染或发生癌变的细胞。NK细胞分泌的外泌体含有部分NK细胞的活性物质,也具有抗肿瘤的能力。
NK细胞外泌体应用于临床治疗最大的瓶颈在于因为NK细胞在体外无法很好的扩增,从而无法获取足够数量的外泌体。为了解决这一问题,我们采用人工抗原呈递细胞(genetically-engineered artificial antigen-presenting cells,aAPCs)表达的跨膜IL-21来刺激NK细胞的增殖,aNK细胞的扩增数量足以满足临床治疗的需求。经过14-18天的激活和扩增,大量的外泌体由aNK细胞释放进入培养液中,这部分aNK细胞外泌体拥有典型的NK细胞特征蛋白,并对多种肿瘤细胞均具有杀伤能力。
在过去数十年中,抗生素的广泛使用使得微生物耐药频率和其与相关的严重感染性疾病的以令人担忧的速度增加。在革兰氏阳性菌中,最重要的耐药性病原体是耐甲氧西林的金黄色葡萄球菌、耐β-内酰胺的肺炎球菌和多药耐药性肺炎球菌,以及耐万古霉素的肠球菌。肺炎克雷伯氏菌、大肠杆菌和奇异变形杆菌等革兰氏阴性菌中的β-内酰胺酶耐药性是造成革兰氏阴性菌耐药性的重要原因。因此临床治疗迫切需要新颖的抗菌剂,尤其具有新颖作用机制的抗菌剂。
本发明发现激活后的aNK细胞,其外泌体不仅富含NK细胞的胞浆成分,还富含大量的miRNA。这些miRNA在实验中可以显著的抑制细菌的生长,具有出色的抗菌功能,同时发现这些miRNA在实验中可以抑制肿瘤细胞的生长,具有抗肿瘤的功能。
发明内容
本发明的目的在于提供aNK细胞分泌的外泌体,及其包含的miRNA在抗菌和抗肿瘤中的应用。
本发明的目的是通过以下技术方案实现的:一种经跨膜IL-21激活的NK细胞分泌的外泌体在抗菌中的应用。
进一步地,所述外泌体包含一条或一条以上选自SEQ ID NO.1~SEQ ID NO.2144所示序列的miRNA。

具体实施方式
下面结合实施例对本发明作进一步说明。
实施例1:aNK外泌体的获取及其结构特征
利用现有的方法,采用跨膜IL-21滋养细胞扩增NK体系:将来源于志愿者的外周静脉血分离获得PBMC,加入辐照后表达有跨膜IL-21的滋养细胞和IL-2,期间加入完全培养液培养18天。
收集培养18天的aNK细胞培养液,流式细胞仪检测aNK细胞的纯度达到95%以上,并且培养液无细菌和支原体污染。
1.1aNK细胞培养液通过台式低速离心机400g离心5min去除细胞沉淀,收集上清4度保存待用。
1.2采用中空纤维切向过滤系统(Spectrum Laboratories KrosFlo Research IITFF System)对培养液中的外泌体进行纯化。首先,利用0.45μm mPES中空纤维过滤柱(P-S02-E45U-10-N)去除细胞培养液中的细胞碎片;滤出液进一步通过截留分子量在300-kDa的mPES中空纤维过滤柱(S02-E300-05-N)进行浓缩,获得外泌体粗制品;为了进一步缩小体积并且去除残余的培养基和盐离子,用3倍体积的PBS对外泌体粗制品进行稀释,并采用截留分子量在300-kDa的mPES中空纤维过滤柱(D02-E300-05-N)进行浓缩,得到纯度很高的外泌体。
1.3将获取的外泌体用PBS稀释100倍,利用Zetasizer Nano ZSE系统检测外泌体的粒径分布,并用Dispersion Technology Software对检测结果进行分析。如图1所示,大部分aNK外泌体分布在50-150nm,峰值分布在90nm。
1.4用BCA蛋白定量试剂盒对外泌体进行蛋白定量,并用裂解液释放外泌体中的蛋白,采用Werstern blot方法对外泌体Marker蛋白CD63、ALIX,aNK外泌体特有的granzymeA、granzyme B和perforin进行检测。如图2所示,与293T的外泌体相比,aNK外泌体含有NK细胞特有的颗粒酶A、颗粒酶B和穿孔素。
1.5将获取的外泌体用去离子水重悬,取少量外泌体置于有碳涂层的铜网,去除多余的水分,并用2%乙酸铀酰进行染色,自然干燥后利用透射电镜观察外泌体的形态和大小。如图3所示,TEM结果显示分离的aNK外泌体具有典型的外泌体结构,呈现内部半透明、椭圆、大小不一的封闭膜结构。
实施例2:aNK外泌体miRNA测序
根据实施例1获得的aNK外泌体,委托南京世和基因生物技术有限公司对aNK外泌体中miRNA进行测序。采用NEBNext Multiplex Small RNA Library Prep Set forIllumina(NEB,USA)进行建库,并对待测序样本添加测序接头。采用Illumina X-ten PE150平台对样本进行测序,每个样本至少300M reads。为了减少假阳性,信噪比大于100的独立序列纳入miRDeep log-odds score的计算,并设置miRDeep log-odds score的范围为-10~10.为了发掘aNK外泌体中全新的miRNA,以miRDeep score=0作为阈值,所有超过阈值的miRNA作为全新的miRNA,如图4所示,在测序中发现了732个已知的miRNA(SEQ ID NO.1412~SEQ ID NO.2144)。除此之外,全新序列的miRNA有1411个(SEQ ID NO.1~SEQ IDNO.1411)。
实施例3:aNK外泌体抗菌性能以及aNK外泌体联合NK细胞的抗菌性能
为了确定外泌体是否可以抑制细菌生长,选取柠檬酸杆菌(C.R.),大肠杆菌,金黄色葡萄球菌,伤寒沙门氏菌(CT18),金黄色葡萄球菌(LAC),鲍曼不动杆菌(XH386)作为检测对象。将实施例1获得的aNK外泌体按照不同比例和上述6中细菌混合,通过测量光密度(OD)量化细菌的数量。结果如图5所示,与没有外泌体的阴性对照相比,随着外泌体浓度的增加,大肠杆菌,金黄色葡萄球菌,伤寒沙门氏菌(CT18)和金黄色葡萄球菌(LAC)的生长呈现浓度依赖性的显著抑制。同时,通过检测柠檬酸杆菌中荧光素酶活性量化细菌的数量,随着aNK外泌体浓度的增加,生物荧光的强度随之降低,说明aNK外泌体可以浓度依赖性的抑制柠檬酸杆菌(图6)。
进一步的结果表明,aNK外泌体联合NK细胞相对于aNK细胞的抗菌作用有进一步的增强(图7)。
