Description

一种治疗HIV感染的嵌合抗原受体的重组基因构建及其应用
技术领域
本发明涉及感染性疾病免疫治疗技术领域,具体涉及一种治疗HIV感染的嵌合抗原受体的重组基因构建及其应用。
背景技术
艾滋病是由人类免疫缺陷病毒1型(Human Immunodeficiency Virus1,HIV-1)感染引起的一种重大威胁人类生命安全的传染病,据世界卫生组织的最新统计,自发现到2014年底已造成3900多万人死亡,目前世界上艾滋病毒感染者仍有3700万。我国艾滋病毒感染者逐年增加,其总患病人数已突破百万。目前尚无有效疫苗且现有药物不能彻底治愈。
高效抗逆转录病毒治疗(HAART)是HIV/AIDS治疗史上的第一次革命,其极大的降低了HIV/AIDS的发病率和病死率,显著延长了患者寿命,甚至降低了HIV的传播。但也面临着很多挑战:1)患者必须终生服药,需付出昂贵的经济代价;2)严重的毒副作用;3)耐药毒株的出现;4)更为重要的是cART不能彻底清除病毒,主要是因为药物仅对复制中的病毒有效,而对HIV在感染早期建立的潜伏性病毒“储藏库”(reservoir)是无效的。一旦抗逆转录病毒治疗中断,病毒储藏库中的整合前病毒再度激活,几乎所有患者体内病毒血症会迅速反弹。
艾滋病毒在其传播和繁殖过程中的高变异性使得以往有效的艾滋病药物失效,因此出现了后来的“鸡尾酒疗法”,也就是联合多种抗病毒药物来进行高效抗逆转录病毒治疗,但是鸡尾酒疗法同样有着其局限性。综合目前国际上艾滋病研究的前沿和热点问题,研究者普遍认为HIV不能治愈的主要原因是HIV在感染极早期就在机体内建立起隐秘的病毒“储藏库”,即静息记忆的CD4+T淋巴细胞(Resting memory CD4+T)。
要找到治愈艾滋病的一个重大挑战,就是如何能够重新激活潜伏的HIV从而被机体的免疫系统自发识别和清除(shock and kill)。同时,研究发现,即使在接受cART治疗的感染者体内,也出现不可逆转的免疫损伤,特别是细胞毒性T细胞(CTL)的数量减少和功能缺陷,这表明通过抗逆转录病毒治疗重建的机体免疫系统将不能有效的清除那些被激活的细胞,需要通过联合增强机体HIV特异性免疫应答的方法来增强对HIV储藏库的清除效果。因此,对HIV潜伏性病毒“储藏库”的形成及激活策略和以重建机体免疫功能的探索都是迈向治愈HIV时代极有价值的研究方向。
近几年来,基于嵌合抗原受体(chimeric antigen receptor,CAR)肿瘤免疫治疗技术创造了杀伤肿瘤细胞的全新途径。由于其具有高亲和力和MHC(Majorhistocompatibility complex)非依赖性等优点,特别是由两个CD28及4-1BB、CD3ζ偶联形成的3代CAR可增强T细胞的杀瘤能力并延长了其在体内的存活时间,从而在白血病和淋巴瘤等肿瘤免疫治疗中取得了令人鼓舞的成效。其实早在1994年,Roberts等人尝试用CAR-T细胞治疗HIV感染,他们选取CD4序列作为单链抗体用于结合感染细胞表面的gp120,虽然具有部分杀感染细胞功能且经过多年的努力,但最终以失败而告终。其主要原因有以下几个方面:1.使用逆转录病毒载体转导效率较低,为了获得足够的可回输CAR-T细胞,过度的体外扩增导致回输后细胞死亡和CAR分子的丢失。2.CAR分子设计本身存在缺陷,其中CD4结构域可能引起转导的CTLs被HIV感染或者病毒感染细胞通过下调CD4分子的表达而逃脱CAR-T细胞的杀伤。
发明内容
本发明为了克服现有技术的上述不足,提供了一种新的能识别HIV病毒感染细胞表面gp120的单链抗体ScFv以及由此单链抗体制成的嵌合型抗原受体(CAR),称为N6-CAR分子。
本发明的另一目的是提供一种能表达上述N6-CAR的表达载体以及N6-CAR载体基因修饰的CD8+T淋巴细胞。
本发明的再一个目的是提供N6-CAR分子修饰的CD8+T淋巴细胞在制备抗HIV感染药物方面的用途。
为了实现上述目的,本发明是通过以下技术方案实现的:
提供了一种单链抗体ScFv,该单链抗体能够识别HIV病毒感染细胞表面的gp120,是通过串联针对HIV病毒感染细胞表面的gp120的抗体轻链、重链可变区而得,作为整个CAR分子的胞外结合结构域,其氨基酸序列如SEQ ID NO.2所示。
本发明也提供了编码上述单链抗体ScFv的编码基因,该基因的核苷酸序列如SEQID NO.1所示。
本发明还提供了一种治疗HIV感染的嵌合型抗原受体,该嵌合型抗原受体是通过N端到C端顺次拼接信号肽、本发明提供的单链抗体ScFv、CD8hinge、白细胞抗原分化群分子跨膜区CD28-TM及细胞内结构域ICD、4-1BB和白细胞抗原分化群3的ζ链CD3得到的,所得到的嵌合型抗原受体的氨基酸序列如SEQ ID NO.4所示。
本发明同时提供了编码上述的嵌合型抗原受体N6-CAR的编码基因,该基因的核苷酸序列如SEQ ID NO.3所示。
一种含有并能表达氨基酸序列为SEQ ID NO.4所示的嵌合型抗原受体N6-CAR的编码基因的表达载体,所述载体为以PTK881载体为骨架,将CMV启动子替换成EF1α启动子后改造成的PTK-EF1α-N6载体,其核苷酸序列如SEQ ID NO.5所示。
本发明提供了一种基因修饰的CD8+T淋巴细胞,是将PTK-EF1α-N6表达载体转染293T细胞所的慢病毒载体转导CD8+T淋巴细胞,从而获得能表达嵌合型抗原受体的基因工程化的T-淋巴细胞。N6-CAR改造的CD8+细胞对表达gp120细胞系的杀伤效果更加明显。
进一步地,所述的基因修饰的CD8+T淋巴细胞是由以下方法制备得到:从外周血分离PBMC后再用磁珠阳选获得CD8+T细胞,经anti-CD3/28磁珠(细胞与磁珠比例为1:3)刺激12小时后,加入重组有N6-CAR分子的慢病毒感染4小时后补液(MOI=5),从病毒感染后第三天开始,细胞计数并根据细胞状态和增殖情况补加培养基,细胞浓度调整至0.6x106/ml,并补充IL-2 100U/mL,进一步扩增细胞直到满足回输的细胞数。
本发明同时提供了一种上述N6-CAR基因修饰的CD8+T淋巴细胞的用途,所述N6-CAR基因修饰的CD8+T淋巴细胞是应用于制备抗HIV感染的活细胞药物。
本发明的有益效果:(1)本发明中克服早期设计的缺陷,利用能与病毒蛋白Gp120高度特异性结合的广谱中和抗体作为ScFv,能与98%的HIV-1的病毒株结合,增加该CAR-T细胞的广谱性;(2)本发明中使用含有SIN(Self-inactivating)结构的PTK质粒来生产慢病毒载体增加安全性的同时,改造CAR分子细胞内为双刺激分子以其提高N6-CAR-T细胞的扩增和存活特性,增加临床有效性和安全性。(3)本发明中的能表达嵌合型抗原受体的基因修饰CD8+T淋巴细胞在体外实验和体内实验中均发现具有显著的抑制、杀灭HIV病毒的活性,能够作为活性成份制备抗HIV感染药物。

按照SEQ ID NO.4所示序列合成CAR,将全长CAR的编码基因通过基于无缝重组克隆技术插入目的表达载体(见图2)。经过多次试验,首选的质粒载体为以PTK881载体为骨架,将CMV启动子替换成EF1α启动子后改造成的PTK-EF1α-N6载体(其核苷酸序列如SEQ IDNO.5所示),最终获得了插入CAR基因并能表达CAR的重组质粒PTK-EF1α-N6载体,其核苷酸序列如SEQ ID NO.6所示。
病毒包装步骤如下:
1)取两个均装有16ml DMEM培养液的离心管,向其中一管加入960μg PEI,另一管加入320μg预混的PTK881载体质粒,漩涡震荡,室温平衡10分钟。
2)取一个10ml的移液管将混有PEI的培养基吹起来,将混有质粒的培养基一滴一滴地加入PEI中,室温温育30分钟。
3)取一个T175瓶,向其中加入3ml胎牛血清,将和PEI混合的PTK-EF1α-N6载体质粒加入其中,然后将多层细胞培养瓶中的培养基倒入到T175瓶,上下左右颠倒与质粒混匀,最后将T175瓶中的培养基倒回到多层细胞培养瓶中。37℃,5%CO2培养箱培养3天,收获上清。收集的上清4000rpm(3000g),30min离心去除293T细胞碎片。
4)将慢病毒液上清用0.22μm滤膜过滤后,分装到250ml的离心瓶中,于4℃,30000g离心2.5小时,离心后将离心瓶小心转移至生物安全柜,用真空泵去上清,留沉淀,加入T细胞培养基500μl/离心瓶,用枪将沉淀吹散混匀,即得到含N6-CAR分子的慢病毒载体,立即使用或分装后于-80℃保存。
实施例3:制备能表达嵌合型抗原受体的CD8+T细胞(CAR-T细胞)
步骤1:分离患者PBMC细胞
(1)采集人外周血样本60-80ml,边采集边摇晃使得外周血与抗凝剂充分混合;
(2)将外周血转入50ml离心管中,用DPBS缓冲液按1:1稀释外周血,混匀。将稀释好的血样缓慢加入室温的15ml人淋巴细胞分离液的离心管中。方法如下:用10ml移液管吸取血样,伸至分离液液面上方0.5cm处,血样自然滑落铺至分离液面上,然后轻轻加入血样,注意不要冲破液面;
(3)配平离心30min,慢升慢降;
(4)离心完成后,离心管出现明显分层由下至上:红细胞层,粒细胞层,Ficoll层、单个核细胞层和血浆层。吸取血浆层至距白膜层5mm左右处弃之。小心吸取红细胞层以上的所有液体至离心管中,PBS稀释,与细胞悬液体积比应大于1:3,混匀。
(5)离心(1600r/min)5min,PBS重悬细胞混匀,取少量细胞计数。
(6)离心300g(1200r/min)5min,上清液送检无菌检测。
步骤2:分选CD8+T细胞
(1)步骤1中的PBMC细胞,用30ml生理盐水重悬后取样计数(取样完后,补加至50ml混匀,500g、10min、18℃、升快、降快离心,去上清),计数后按每107/80μL buffer混匀(如果上清没有去干净,建议不用加buffer),加入按每107/20μL CD8Microbeads重悬,4-8℃孵育15min。
(2)孵育完成后,使用按每107个1~2ml buffer洗细胞,500g、10min离心。
(3)用500μL buffer重悬多达108个细胞(若细胞数目比较多,buffer使用的也会多)。
(4)将美天旎专用LS柱,置于磁力架上,使用3ml buffer冲洗LS柱后,将细胞重悬液加入到LS柱里,使之流尽。用3ml buffer洗LS柱三次,每次需要流尽。将LS柱离开磁力架,使用5ml buffer,加入到LS柱中,用活塞将标记后的细胞冲洗出来(可以冲洗两次,确保标记的细胞均可以冲洗出来)。
(5)CD8+T细胞冲洗出来后,用生理盐水重悬至30ml,取样计数,500g、10min、18℃离心,得细胞沉淀,即可用于培养。
步骤3:CD8+T细胞激活
(1)将步骤2中CD8+T细胞,计数,按密度为2x106/ml加入培养瓶中,混匀放入CO2培养箱培养2小时。
(2)取出培养瓶,轻摇,使沉降于底部的悬浮细胞浮起,移液管吸取培养基转入离心管中,少许培养基洗培养瓶将悬浮细胞全部收集,混匀计数。
(3)根据细胞计数调整细胞浓度,按1.2x106/ml的浓度接种培养瓶中(100~120mlin a T150,50~60ml in aT75,15~29ml in aT25),加CD3/CD28磁珠,按细胞与磁珠比例为1:3(加之前磁珠用培养基洗涤3次,去除保存液),加入IL-2100U/mL,混匀放入CO2培养箱培养,收集细胞。
步骤4:CD8+T细胞被转导N6-CAR分子制备CAR-T细胞
加入磁珠12小时后,取适量步骤3中生长状态良好的CD8+T细胞悬液,放入离心管中300g离心5分钟。弃去上清液,以1x106/ml细胞的比例加入嵌合型抗原受体(CAR)病毒载体,同时加入终浓度4μg/ml的Polybrene,混匀。将细胞悬液在37℃条件下小体积孵育。孵育4小时后补加适量T细胞完全培养基进行培养。细胞培养的第3天,细胞计数并根据细胞状态和增殖情况补加培养基,细胞浓度调整至0.6x106/ml,并补充IL-2100U/mL。细胞培养的第5天,细胞混匀转离心管中,在磁力架上去除磁珠,细胞计数并补加培养基,并补充IL-2100U/mL,细胞密度调整至0.6x106/ml继续培养。并利用流式检测SCFV的表达,同时,取部分CD8+T淋巴细胞经goat anti-human Fab antibody抗体刺激并连续传代,以确定anti-gp120CAR转导的CD8+T淋巴细胞自扩增能力,结果如图3所示。
结果表明,Anti-gp120CAR病毒转导细胞培养到五天后,有40%的CD8+T细胞表达CAR分子。当抗体goat anti-human Fab antibody特异性地与CD8+T细胞表达CAR分子结合后,能有效和剂量依赖地激活细胞的增殖,随着传代次数增加,CAR分子阳性细胞种群比例也逐渐升高。
实施例4:CAR-T细胞体外杀灭HIV感染细胞活性的检测
为了进一步检测N6-CAR的功能,我们将N6-CAR-T细胞与两株HIV-1感染的细胞系H9-NL4-3和H9-NDK分别进行混合培养,在U形底的96孔板中进行细胞杀伤实验。首先利用Calcein-AM标记HIV感染细胞系H9和阴性对照细胞,取100μl(含靶细胞数量104)于96孔板中,取100μl梯度稀释的CAR-T细胞加入相应的96孔板中,确保效靶比范围为5:1到10:1,每孔终体积为200μl。室温200g离心30分钟,37℃孵育2-3小时。离心取上清测定荧光并计算出裂解百分数并用于判断N6-CAR-T细胞对HIV感染细胞的细胞毒性,实验结果如图4所示。
结果显示,从5:1到10:1效靶比区间范围内,N6-CAR-T细胞以剂量依赖的方式显著杀伤两个毒株HIV感染的靶细胞系,而对对照靶细胞没有明显的杀伤效果,说明N6-CAR-T细胞杀伤靶细胞作用是HIV-gp120特异性的。
实施例5:共培养条件下CAR-T细胞体外抑制病毒复制活性的检测
为了进一步证明N6-CAR-T细胞在清除野生型HIV-1感染的原代CD4+T细胞方面的有效性,利用野生型HIV-1NL4-3-EGFP和NDK-EGEP两个毒株分别感染健康人血液样本中分离的CD4+T淋巴细胞,感染后3小时换液。感染后的第8天,该细胞与N6-CAR改造的同源CD8+T淋巴细胞以1:4的比例混合,在24孔板中进行细胞杀伤实验。靶细胞数量为106/孔,RMPI1640完全培养基体积为500μl/孔。48小时后,通过流式细胞术检测EGFP+CD4+T淋巴细胞的比例,验证N6-CAR-T细胞的杀伤作用,实验结果如图5所示。
结果表明,以未经CAR分子改造的CD8+T细胞组为参照,N6-CAR-T细胞组能清除其中99.5%的HIV-1感染的细胞,表现出显著的杀伤效果,充分展示了N6-CAR-T细胞的特异性和高效性。
实施例6:CAR-T淋巴细胞在体内杀灭感染HIV病毒细胞的活性检测
为了进一步证明Anti-gp120CAR-T淋巴细胞能否在体内清除HIV感染的细胞,我们将带有荧光基因的NL4-3-EGFP病毒(1x106pg p24/mouse)静脉注射到人源化小鼠BLT体内,感染小鼠同时,从健康志愿者分离PBMC然后分离CD8+T细胞,转导N6-CAR慢病毒,体外扩增10天后,计数后用500μl PBS重悬,按1x107CD8+T/kg的剂量静脉回输。两周后,从小鼠体内收集脾脏,放入包埋剂中制备冷冻切片。制备大于20张的10μm厚度的冷冻切片,在荧光共聚焦显微镜下照相,将相片利用Velocity5.0软件进行量化分析(图6A)。同时,以收集到的部分脾脏细胞制备单细胞悬液,取5x106细胞于DNAzol来提取基因组DNA,利用Nested-QPCR定量前病毒的拷贝数来评估体内所有感染HIV的细胞数目(图6B)。
结果表明,与未接收CAR-T细胞治疗的对照组相比,病毒蛋白表达水平和病毒基因组水平显著性各减少97.1%,证实了CAR-T细胞能在体内进行有效地裂解和清除HIV感染的细胞,为CAR-T细胞进行人体临床测试奠定理论基础。
