Description

一种靶向HIV病毒囊膜双位点的嵌合抗原受体及其表达载体 和应用
技术领域
本发明涉及医药生物领域,具体是指一种靶向HIV病毒囊膜双位点的嵌合抗原受体及其表达载体和应用。
背景技术
艾滋病(Acquired immunodeficiency syndrome,AIDS)是由人类免疫缺陷病毒(Human immunodeficiency virus,HIV)感染引起的疾病,已成为当今世界最危险的流行病之一,严重威胁人类的生存,对人口健康和社会经济的发展产生巨大的影响。
目前上市的抗药物主要包括:蛋白酶抑制剂、逆转录酶抑制剂,包括核苷类逆转录酶抑制剂和非核苷类逆转录酶抑制剂、整合酶抑制剂、以及进入抑制剂。临床上主要采用联合用药的方式进行治疗,即俗称“鸡尾酒疗法”的高效抗逆转录病毒疗法(Highly activeanti-retroviral therapy,HAART)。高效抗逆转录病毒治疗是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,HIV感染者非艾滋病相关疾病的发病率和病死率正在增加,如肾脏、肝脏和疾病。即使进行cART治疗,感染HIV的老年患者年龄相关疾病,如糖尿病、心血管疾病、肾疾病和骨疾病的发生明显早于非HIV感染的同龄人,这些跟抗病毒药物的不良反应息息相关;(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。对此,开发出新的有效的治疗方式已迫在眉睫。很多文献报道,病毒及感染细胞表面的gp120/gp41复合物很不稳定,gp120容易脱落,特别是在与中和抗体结合后,因此,这可能导致anti-gp120CAR-T结合gp120后从感染细胞表面脱落,影响CAR-T效果。
HIV囊膜蛋白(Env;gp160三聚体)是病毒粒子表面上的唯一抗原,Env的作用是,通过与宿主细胞受体发生相互作用帮助病毒进入细胞。成熟的Env(gp160)3被酶切后成(gp120/gp41)3,是由三个gp120和三个gp41亚单元组成的三聚体。其中,gp41是跨膜蛋白,gp120位于表面,并与gp41通过非共价作用结合。在病毒入侵过程里,gp120结合细胞表面受体CD4和复合受体CCR5或CXCR4,触发Env巨大的构象变化,然后gp41膜融合蛋白又通过一连串的大范围的蛋白质重折叠,最终导致病毒与宿主细胞的膜融合。考虑到gp120容易脱落,导致病人体内存在大量游离的gp120蛋白,这些蛋白可能与anti-gp120 CAR-T结合,从而与活性复制的和激活的潜伏细胞表面表达的gp120竞争,干扰CAR-T的活性。
本发明通过优化设计,提供了一种HIV病毒靶向性嵌合抗原受体,分别靶向HIV囊膜的gp120区和gp41区,双CAR由两个不同单链抗体(scFv)串联,或由两个单链抗体(scFv)的CAR并联。其中两个不同单链抗体均能中和HIV-1毒株。应用本发明实施例提供的技术方案,该抗原受体实现了同时识别所有的病毒株,降低免疫逃逸风险的同时对毒株具有更好的杀伤效果,能够作为活性成份制备抗HIV感染的活细胞药物。

图22表明,在三个效靶比(25:1,5:1,1:1)的条件下,针对HIV囊膜两个位点的双特异性CAR-CD8+T对293T-gp120-gp41阳性靶细胞的杀伤效果明显优于两个单CAR-T的联合(gp120 CAR-CD8+T和gp41 CAR-CD8+T,指4E10)。
2.小鼠模型体内抗病毒试验
在BSL-3实验室内,首先构建人源化小鼠,4-6周龄(B-NSG,北京维通利华公司)小鼠经2Gy辐照后,尾静脉注射2x105 CD34+造血干细胞(HSC,购自TPCS公司),6周后取小鼠外周血进行流式分析,通过人源T(CD4+和CD8+)细胞的比例判定模型是否成功建立。然后再进行HIV感染模型,在Day 0天通过静脉注射1x 106pgp24 HIV-LUC病毒,在Day 10成像后注射CAR-CD8+T细胞。从Day10开始,每3-4天成像一次,在准备动物成像之前,以150mg/kg的剂量腹腔注射D-luciferin(Molecular Imaging Products,Bend,USA).5分钟后,腹腔注射75mg/kg的戊巴比妥钠麻醉小鼠,等5分钟后使用IVIS小动物活体成像系统(Xenogen,Hopkinton,USA)。成像结果见图23,充分说明针对HIV囊膜两个位点的双特异性C7-CAR-CD8+T和C9-CAR-CD8+T比单CAR-T(gp120 CAR-CD8+T和gp41 CAR-CD8+T,指10E8)及其联合对体内病毒感染细胞的清除效果好,荧光信号的强弱代表病毒感染细胞的数量和病毒在细胞内的载量。
