Description
技术领域
本发明属于细胞治疗领域,具体地说,涉及一种嵌合抗原受体基因工程载体、免疫细胞及其应用。该基因工程载体经病毒包装后可以稳定转染自体或者异体免疫细胞,通过双靶向识别达到特异性杀伤体内具有靶分子的目的细胞,从而起到临床治疗作用。
背景技术
嵌合抗原受体-Chimeric antigen receptor,简写为CAR。其中基于T细胞的嵌合抗原受体细胞治疗简称CART治疗,基于NK细胞的嵌合抗原受体细胞治疗简称CAR-NK治疗,也有基于γ/δT细胞的嵌合抗原受体细胞治疗,称为为Universal-CAR。不管采用哪种细胞,均是利用相应免疫细胞对靶细胞的强大的杀伤能力,达到清除体内肿瘤和某些类型细胞的作用。
自国际上首例复发的急性淋巴细胞白血病患者接受CART治疗到现在,对于复发难治B系急性淋巴细胞白血病和淋巴瘤的疗效取得了显著的临床疗效,并得到了业界公认。CART治疗技术经历了不断的更新,从最早的一代CART鲜有临床疗效,到二代CART取得显著疗效,后者是在一代CART的基础上增加了共刺激分子,如4-1BB或CD28。三代CART是在二代CART的基础上增加了两种共刺激分子,但一般认为三代CART不比二代CART具有优势,因此目前主流的还是基于二代CART技术进行的嵌合抗原受体治疗。
二代CART技术主要是针对肿瘤细胞膜表面抗原,将可识别该抗原的抗体分子中的轻链和重链可变区,通过连接肽进行串联,形成单链亲和抗体结构,然后与铰链区/跨膜区、共刺激分子和效应器分子进行病毒制备后在免疫细胞中融合表达,使得相应的免疫细胞具有特异性杀伤靶细胞的作用。目前基于CD19、CD20、CD30、CD33、GD2、BCMA、EGFR VIII、Mesothelin、CD138、CD38等的CART载体构建均是采用相同的融合表达策略。当前,基于嵌合抗原受体细胞治疗技术对于CD19阳性淋巴细胞白血病和淋巴瘤取得了非常显著的疗效。联合PD-1抗体和CART细胞治疗是一个不错的选择,目前有很多临床实验正在进行中。
然而,CART细胞应用于癌症治疗,在显示出疗效的同时,伴随有毒性和风险,甚至导致病人死亡。主要面临的问题有两个,首先,细胞因子释放综合症(cytokines releasesyndrome,CRS)是最显著的毒性,为头号安全风险。细胞因子释放综合症是基于T细胞的激活,是T细胞激活活性的一个反应,所以副作用是与CART的治疗机制正相关的临床反应。高度增殖的T细胞能引起CRS,表现为高热和肌痛,不稳定的低血压和呼吸衰竭。一般而言,CRS风暴的严重程度与患者接受CART治疗前体内的肿瘤细胞负荷有很大的相关性,但不排除少数患者在低负荷的情况下也会产生比较严重的CRS。其次,少数患者出现急性脑水肿,我们推测是由于患者基因组中转录翻译成为神经元细胞膜上某个蛋白的编码序列存在多态性(single nucleotide polymorphisms,SNP)或者突变(single nucleotide variant,SNV),使得其抗原表位在结构上与CD19抗原表位结构上趋同,从而导致CART细胞对CD19阳性白血病细胞产生杀伤的同时,也产生了针对自身神经元细胞的细胞毒作用(脱靶效应),并且我们觉得应该称为CART相关急性坏死性脑炎(CART related acute necroticencephalitis,CANE)更为合适。综上,目前一代、二代及三代的嵌合抗原受体仍然存在治疗副作用多、特异性差等问题。有鉴于此特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足,提供一种嵌合抗原受体基因工程载体、免疫细胞及其应用。本发明的嵌合抗原受体基因工程载体安全性好,转染效率高,转染的免疫细胞能够快速扩增,杀伤效果大大提高。另外,本发明较单一靶点的嵌合抗原受体免疫细胞对靶细胞的识别更加精准,防止单一靶点的脱靶效应。
为解决上述技术问题,本发明采用技术方案的基本构思是:
本发明的第一目的是提供一种嵌合抗原受体基因工程载体,包括慢病毒载体骨架、连接在慢病毒载体骨架上的调控元件和嵌合抗原受体基因序列,所述的调控元件包括WPRE元件、cPPT元件和RRE元件。
本申请将Gag(编码病毒结构蛋白)、Pol(编码病毒所需酶类蛋白)、Env(编码病毒膜蛋白)和Rev(编码一个可作用于Rev反应元件,即RRE的蛋白,调节病毒mRNA的细胞核外转运)等慢病毒所需元件放到三种不同的载体中表达,形成三质粒系统,大大降低了病毒重组的概率,可以确保人体使用的安全性。通过对入组患者的检测,最长患者治疗后10个月,体内未检测到慢病毒分子存在。
本申请的慢病毒载体骨架可以为常用的慢病毒载体,例如HIV-1来源的病毒载体。WPRE元件有助于提高病毒mRNA分子的稳定性,cPPT元件有助于病毒向细胞核内转移,从而更容易进行基因组的整合,提高稳定转染效率,而RRE元件有助于mRNA分子的核外转运,从而使得包装获得的病毒滴度高,病毒活力强,这是提高转染效率的关键。由于只有病毒转染阳性的细胞才具有特异性杀伤肿瘤细胞的作用,提高转染效率可以大大降低培养细胞的体系,节约前期生产成本。
进一步的方案,所述的嵌合抗原受体基因序列的上游插入有哺乳类组成型启动子,优选EF1A启动子。本申请的载体优选采用EF1A启动子启动外源基因的表达,EF1A启动子为人延长因子1α来源的哺乳动物组成型表达启动子,使得外源基因表达十分稳定,并且不受细胞类型的影响,可广泛用于T细胞、NK细胞、巨噬细胞等不同细胞类型。相对于CMV、SV40等启动子,除不受细胞类型影响外,更为重要的是外源蛋白表达稳定,不会过高的表达,从而对细胞生长影响小,这是CAR阳性T淋巴细胞在体外高速扩增的基础。
进一步的方案,所述的嵌合抗原受体基因序列包括独立表达的共刺激信号通路序列和效应器信号通路序列;或者,所述的嵌合抗原受体基因序列包括融合表达的共刺激信号通路序列和效应器信号通路序列。
独立表达的共刺激信号通路序列和效应器信号通路序列之间连接有自剪切序列;共刺激信号通路序列和效应器信号通路序列分别独立跨膜表达,且在同时与靶位点结合、被激活时产生效应。本申请载体上的共刺激信号通路序列和效应器信号通路序列,在表达后为两条独立的跨膜的信号通路融合蛋白,一条为共刺激信号通路,一条为效应器信号通路;当两条信号通路均被激活时,嵌合抗原受体基因工程载体所修饰的免疫细胞才能够被激活,对靶细胞产生杀伤作用。当只有一条通路被激活时,免疫细胞不能够被激活,也不能产生杀伤作用。因此,与单一靶点的嵌合抗原受体免疫细胞对靶细胞的识别相比,这种方式更加精确;同时双靶向的联合识别作用也可以更好的防止单一靶点的脱靶,增强对靶细胞的特异性和杀伤力。
有研究发现CD19-CART治疗患者中部分患者出现急性脑水肿等严重危及生命的副反应,我们分析可能是患者神经元细胞中某种膜蛋白分子发生了突变,从而结构上与CD19抗体识别的抗原表位相近,造成了脱靶效应。而采用本申请的针对CD19抗原不同的抗原表位(至少两个抗原表位)的ScFv抗体,可以在很大程度上避免类似严重不良事件发生。
本申请提供的嵌合抗原受体基因工程载体策略,也可以也包括采用IRES和/或双启动子载体和/或多启动子载体等构建的嵌合抗原受体载体。
进一步的方案,所述的共刺激信号通路序列按照转录方向包括依次连接的第一引导肽序列、第一抗体序列和共刺激分子序列,所述的效应器信号通路序列按照转录方向包括依次连接的第二引导肽序列、第二抗体序列和效应器分子序列;所述的共刺激分子序列与第二引导肽序列之间,或者效应器分子序列与第一引导肽序列连接有自剪切序列。
第一引导肽序列和第二引导肽序列表达相同或不同的引导肽,能够分别引导共刺激信号通路序列表达的蛋白、效应器信号通路序列表达的蛋白至细胞膜;第一抗体和第二抗体位于细胞膜表面。当靶细胞表面存在与两个抗体分别作用的分子时,本申请的两个抗体分别与其结合,导致抗体结构发生改变,产生的信号可以激活其下游融合的蛋白。第一抗体产生的信号激活其下游的共刺激分子,第二抗体产生的信号激活其下游的效应器分子;共刺激分子和效应器分子均被激活后,导致ZNP70激活,这样免疫细胞,也就是CART细胞就激活了,且产生各种细胞因子,能够对靶细胞产生快速、特异性高的杀伤作用。
进一步的方案,所述的第一抗体序列或第二抗体序列包括但不限于:与靶细胞的细胞膜表面分子相互作用的分子序列、与靶细胞内部递呈到其细胞膜表面的特异分子相互作用的分子序列。抗体可以与靶细胞的细胞膜表面原有的分子设计的序列发生相互的结合作用包括:与靶细胞的细胞膜表面抗原作用,或者与非抗原蛋白作用。另外,靶细胞内表达的蛋白经降解等过程而递呈(包含但不限于MHC递呈途径)到细胞膜表面的蛋白片段或短肽所形成的特异性嵌合抗原受体靶点,抗体也可以与此类靶点结合而被激活。本申请中的双靶向是指该嵌合抗原受体基因工程表达载体上同时插入了两种针对靶细胞表面的两种相同或者不同的分子(抗原)所对应的ScFv抗体序列。优选的,第一抗体序列或第二抗体序列均为ScFv抗体序列,选自:与靶细胞的细胞膜表面抗原相互作用的分子序列。
进一步的方案,第一抗体序列或第二抗体序列选自:CD1、CD2、CD3、CD4、CD5、CD7、CD8、CD9、CD10、CD11a、CD11b、CD13、CD14、CD15、CD19、CD20、CD21、CD22、CD23、CD25、CD27、CD28、CD30、CD33、CD34、CD36、CD37、CD38、CD40、CD41、CD42、CD43、CD44、CD45、CD56、CD58、CD66c、CD70、CD73、CD74、CD80、CD81、CD86、CD94、CD97、CD99、CD102、CD123、CD133、CD134、CD137、CD138、CD200、GD2、EGFR VIII、GD3、NG2、CA125、A33、CEA、CEACAM6、CS1、EGFR、ERBB2、FGF19、HER3、IL3Ra、NCAM、NKG2A、BCMA、NTBA、PD-1、PDL-1、PSMA、PSGL1、ROR1、VEGF中的至少一种。
进一步的方案,第一抗体序列和第二抗体序列的组合选自:CD19/CD19、CD19/CD20、CD19/CD123、CD19/CD66c、CD19/CD58、CD19/CD56、CD19/CD13、CD19/CD33、CD19/CD44、CD19/CD73、CD19/CD86、CD19/CD86、CD19/CD99、CD19/CD24、CD19/CD200、CD19/CD97、CD19/BDCA4、CD19/CD133、CD19/CD15、CD19/NG2、CD19/sIgM、CD20/CD20、CD20/CD20、CD20/CD123、CD20/CD66c、CD20/CD58、CD20/CD56、CD20/CD13、CD20/CD33、CD20/CD44、CD20/CD73、CD20/CD86、CD20/CD86、CD20/CD99、CD20/CD24、CD20/CD200、CD20/CD97、CD20/BDCA4、CD20/CD133、CD20/CD15、CD20/NG2、CD20/sIgM、CD22/CD22、CD22/CD22、CD22/CD123、CD22/CD66c、CD22/CD58、CD22/CD56、CD22/CD13、CD22/CD33、CD22/CD44、CD22/CD73、CD22/CD86、CD22/CD86、CD22/CD99、CD22/CD24、CD22/CD220、CD22/CD97、CD22/BDCA4、CD22/CD133、CD22/CD15、CD22/NG2、CD22/sIgM。上述组合可以单一,或者联合使用,从而可减少由于靶点丢失造成的治疗失败。优选地,采用CD19/CD19的组合。
上述方案中提到的不同ScFv抗体组合,是根据急性白血病细胞独特的免疫表型特征设计的,上述组合中CD19和CD22基本上是所有B系白血病细胞都表达的细胞膜抗原,而CD20是所有B系淋巴瘤淋巴瘤均表达的细胞膜抗原,同时联合相同的抗体序列或者其它抗体序列,可以做到特异性杀伤肿瘤细胞的作用,同时对正常的B淋巴细胞没有影响。我们进行了双靶向嵌合抗原受体的临床实验,11例入组患者均在CART细胞输注后8~28天获得分子缓解(MRD<0.01%),从而证明了上述基于双靶向嵌合抗原受体治疗的有效性。
或者,所述的第一抗体序列和第二抗体序列还包括针对靶细胞内表达的蛋白经降解等过程而递呈到细胞膜表面的蛋白片段或短肽所形成的特异性前核抗原受体靶点设计的抗体序列。具体是指细胞内一些肿瘤源性基因突变蛋白产物或异常表达蛋白产物经蛋白酶体或其它机制降解后,经MHC分子或其它分子递呈到细胞膜表面,可以作为免疫细胞识别的靶点。针对这些递呈的肿瘤细胞突变蛋白产物或异常表达蛋白产物设计相应的抗体序列,经组装成嵌合抗原受体基因工程载体和病毒,通过转染免疫细胞并表达,可以识别特定的肿瘤细胞从而产生靶向杀伤作用。

采用上述技术方案后,本发明与现有技术相比具有以下有益效果:
1、本发明通过改造嵌合抗原受体基因工程载体,插入调控元件、启动子、优化碱基序列等使载体的安全性好,转染效率高,转染的免疫细胞能够快速扩增,杀伤效果大大提高。
2、本发明通过采用双靶向的嵌合抗原受体基因工程载体作为CART治疗的的载体,相应的载体经病毒包装后可以进行自体或异体免疫细胞(T细胞和/或NK细胞和/或γ/δT细胞)的转染和扩增,用以细胞免疫治疗。双靶向嵌合抗原受体可以针对细胞膜表面的一种或者几种抗原设计,相同抗原可以为相同或者不同的ScFv序列。嵌合抗原受体与靶细胞膜表面抗原结合后,经过信号转导,可以实现共刺激信号分子和效应器信号分子的同时且单独激活,从而激活修饰的免疫细胞发挥抗肿瘤等的作用。因此,与单一靶点的嵌合抗原受体免疫细胞对靶细胞的识别相比,这种方式更加精确;同时双靶向的联合识别作用也可以更好的防止单一靶点的脱靶,增强对靶细胞的特异性和杀伤力。另外,能够降低与正常细胞表面类似的或者异变分子的结合作用,减少了其攻击正常细胞的几率,提高了使用的安全性。
3、本申请的嵌合抗原受体序列中,跨膜区序列与共刺激信号分子或者效应器信号分子之间没有linker,能够缩短信号通路,提高信号转导效率,从而使得T细胞等免疫细胞的激活效率提高,对于提高CART细胞的体外杀伤效果非常重要。
下面结合附图对本发明的具体实施方式作进一步详细的描述。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对实施例中的技术方案进行清楚、完整地描述,以下实施例用于说明本发明,但不用来限制本发明的范围。
实施例1:1)首先,构建嵌合抗原受体基因工程载体。通过基因合成的方法合成相应的序列,并测序验证。选择合适的酶切位点将上述序列插入到腺病毒、逆转录病毒或慢病毒载体中合适的位置,并经测序验证。如图1和图2所示,嵌合抗原受体基因工程载体包括:
RRE序列插入到载体的多克隆位点的上游,WPRE序列和cPPT序列插入到多克隆位点的下游,EF1A启动子插入到RRE序列与多克隆位点的上游之间,用于启动插入多克隆位点的嵌合抗原受体基因。对嵌合抗原受体结构蛋白上游的序列进行优化,优化后序列如SEQID NO60所示,使得外源蛋白表达稳定且持续,对于提高CART细胞的体外杀伤效果非常重要。
引导肽序列构建:膜蛋白引导肽序列,优选引导肽序列见SEQ ID NO:1~10。
与靶细胞上A或B靶点对应的第一抗体和第二抗体的序列,也就是ScFv抗体轻链VL序列和重链VH序列构建:针对急性白血病和淋巴瘤,我们选择SEQ ID NO:11~40中的序列,可以选择相同的或者不同的两个序列用于这些疾病的细胞免疫治疗。以CD19为靶点治疗CD19阳性白血病和淋巴瘤的的ScFv抗体轻链VL序列和重链VH序列为例,可以选择SEQ IDNO:11~14,19~40中的序列,可以选择相同的基于CD19的上述序列用于B系恶性肿瘤的细胞免疫治疗。针对神经母细胞瘤,我们选择SEQ ID NO:19~20,41~50中的序列。
连接肽序列构建:指将VL和VH串联起来的氨基酸序列,优选的序列见SEQ ID NO:51中提供的序列。铰链区序列构建:指介导激活信号从ScFv传递到跨膜区的氨基酸序列,优选的序列见SEQ ID NO:52中提供的序列。跨膜区序列构建:是指介导激活信号从铰链区跨膜传递到胞内区的氨基酸序列,优选的序列见SEQ ID NO:53中提供的序列。共刺激分子序列构建:是指包含但不限于4-1BB、OX40、CD2、CD27、CD28、CDS、ICAM-1、LFA-1(CD11a/CD18)、ICOS等分子的序列。优选地,4-1BB的序列见SEQ ID NO:54中提供的序列。自剪切序列构建:指包含但不限于P2A、T2A、F2A、E2A、BmCPV2A、BmIFV2A等,优选地,P2A序列见SEQ ID NO:55~58中提供的序列。效应器分子序列:是指包含但不限于CD3δ序列,相应的序列见SEQ IDNO:59中提供的序列。
序列组装:除了一般的表达载体组件,以CD19为靶点的嵌合抗原受体基因工程载体序列组成包含但不限于下述结构:CD8引导肽—CD19ScFv—铰链区—CD8跨膜区—4-1BB—P2A—CD8引导肽—CD19ScFv—铰链区—CD8跨膜区—CD3δ-TGA。本申请的跨膜区序列与共刺激信号分子或者效应器信号分子之间没有linker,能够缩短信号通路,提高信号转导效率,从而使得T细胞等免疫细胞的激活效率提高,对于提高CART细胞的体外杀伤效果非常重要。
通过设计合适的酶切位点,将上述序列进行酶切后与采用相同酶切的载体进行连接,连接产物转化DH5α或stbl3感受态大肠杆菌,阳性克隆接种后过夜,细菌抽提质粒后酶切鉴定和送测序。测序结果完全正确的载体即为本实施例的嵌合抗原受体基因工程载体。共刺激信号通路序列和效应器信号通路序列分别表达后的双靶向嵌合抗原受体的结构如图3所示。
其次,通过将上述载体和病毒包装质粒进行合适比例混合,转染293T细胞72h和96h后收集培养上清并进行病毒浓缩。再次,通过实时定量PCR方法,结合病毒的不同浓度梯度转染293细胞进行病毒滴度的确定。再次,通过收集人外周血不同的免疫细胞进行上述病毒的转染,确保转染效率在20%以上,从中找到合适的MOI值用于临床治疗。需要指出的是,每批病毒均需要进行上述操作,确保临床试验的疗效稳定可靠。
再次,通过转染人外周血不同的免疫细胞进行转染效率的检测,对CD19为靶点的CART而言,采用针对ScFv的Fab片段作为流式细胞检测阳性转染效率的客观依据。也可以采用实时定量PCR的方法进行转染效率的检测方案。
再次,通过将病毒转染的CART细胞等免疫细胞与CD19阳性细胞株进行一定比例混合和共孵育,在0h、24h和48h后通过流式细胞技术进行体外杀伤检测,比较不同孵育时间的细胞杀伤效果并与对照病毒进行比较。
再次,通过采集外周血0.5~1ml/Kg,磁珠分选获得CD3阳性T细胞或者CD56获得NK细胞,或者TCRγ/δ分选获得γ/δT细胞,加入CD3/CD28免疫磁珠进行刺激激活和病毒转染,继续给予CD3/CD28免疫磁珠、Interleukin7和Interleukin15进行体外扩增,一般7~8天可以扩增100倍以上,达到合适细胞数量后经洗涤回输人体。回输人体CART阳性细胞数量在1×104/Kg~5×107/Kg,并根据体内负荷进行调整,优选地在2×105/Kg~2×107/Kg。
由于病毒转染阳性的细胞才具有特异性杀伤肿瘤细胞的作用,提高转染效率可以大大降低培养细胞的体系,节约前期生产成本。同时转染阴性的细胞在培养时也会被CD3/CD28免疫磁珠激活,与病毒转染阳性的细胞争夺营养,且由于转染阴性的细胞没有产生额外表达外源蛋白的压力,培养时间长后会导致转染体系中病毒转染阳性细胞比例的进一步降低。本发明的双靶向嵌合抗原受体载体制备的针对CD19阳性白血病和淋巴瘤病毒,经体外转染后一般转染效率在20%以上,绝大部分在40~70%之间,如附图4所示,图4中,a~c为其它慢病毒载体包装的转染效率,d~e为采用本项专利技术载体包装的慢病毒转染效率,f为未转染的对照。
本发明的双靶向嵌合抗原受体载体制备的针对CD19阳性白血病和淋巴瘤病毒,经体外转染后按照CART细胞:CD19阳性白血病细胞株=1:10~1:20的比例混合和共孵育,作为试验组;同时采用无关序列制备载体包装获得的病毒作为对照组。两组细胞对靶细胞的杀伤作用的结果如图5所示。其中,图5a-图5c分别为试验组第0天、第1天以及第2天的体外细胞杀伤实验结果;图5d-图5f分别为对照组第0天、第1天以及第2天的体外细胞杀伤实验结果。可以看出,与对照组相比,本方案的CD19双靶向嵌合抗原受体载体制备的病毒转染的CART细胞在24h和48h共孵育后,对靶细胞的杀伤作用大大增强。
试验例1:一例复发的CD19阳性急性淋巴细胞白血病患者经此CD19双靶向嵌合抗原受体载体制备的病毒转染的CART细胞,结果如附图6所示。图6中,6A-6C是CD19双靶向特异性CART细胞输注前残留病的检测结果;6D-6F是输注CD19双靶向特异性CART细胞后第8天的检测结果,MRD为33.1%。说明其在CART治疗后第8天,骨髓MRD达到分子缓解(MRD<0.01%)。
试验例2:一例二次复发后再诱导失败的CD19阳性急性淋巴细胞白血病患者经此CD19双靶向嵌合抗原受体载体制备的病毒转染的CART细胞,结果如附图7所示.图7中,7A-7C是CD19双靶向特异性CART细胞输注前残留病的检测结果,MRD为11.7%;7D-7F是输注CD19双靶向特异性CART细胞后第8天的检测结果。说明在CART治疗后第8天,骨髓MRD达到分子缓解(MRD<0.01%)。
试验例3:一例骨髓复发的CD19阳性淋巴母细胞性淋巴瘤/白血病患者经此CD19双靶向嵌合抗原受体载体制备的病毒转染的CART细胞后检测结果如图8所示。图中,如8A-8C所示,没有输注CART细胞前,骨髓中有大量的肿瘤细胞,MRD=95.6%,而其在CART治疗后第8天,骨髓中仅有少量肿瘤细胞(MRD=0.012%),如8D-8F所示;CART治疗后第28天,骨髓MRD达到分子缓解(MRD<0.01%),如8G-8I所示,说明治疗的过程快速且有效。
试验例4:CART细胞的体外扩增实验发现,如图9所示,采用本申请双靶向嵌合抗原受体载体制备的慢病毒、Novartis慢病毒载体在体外转染人T淋巴细胞后的生长大为不同。其它公司的病毒转染后CART细胞在7天的时间内扩增了14倍左右,而本申请载体转染的CART细胞在7天的少见内扩增了160倍,体外扩增速度大大提高。由于这些患者均处于疾病终末期,体外培养扩增时间的缩短对于治疗安全非常重要。
试验例5:将本发明制备的病毒转染的CART细胞与来自Novartis的CART细胞进行了体外杀伤实验的比较,实验结果如图10所示。结果表明,与Novartis公司的CD19-CAR杀伤效果对比,本发明的双靶向基因工程载体制备获得的CART细胞(Double-CAR-CD19)的体外杀伤活性明显增强,其结果如图10所示。其中,图10A为输注0小时效果的比较,图10B为输注16小时的效果比较。
试验例6:将本申请的体外杀伤作用与专利CN103483452A中的技术进行了比较,本申请着重提出效靶比的问题。效靶比是效应器细胞(CART细胞):靶细胞(肿瘤细胞),我们在1:10~1:20的时候可以获得99.9%的杀伤效果,专利CN103483452A中做的是1~50:1,得到的杀伤效果也达不到本申请的水平。如图11所示。说明:采用E:T不同比例组合进行体外杀伤实验,在E:T=1:20时,可以将99.9%的靶细胞杀死,而专利CN103483452A的CART在E:T=50:1时尚达不到上述杀伤效果,值得注意的是,由于T细胞与靶细胞存在非特异性杀伤,在E:T=1:1或更低时,专利CN103483452A的CART细胞与对照无显著差异。
试验例7:我们在体外研究中发现,转染阳性的CART细胞中CD4与CD8细胞的合适比例是取得更好细胞毒作用的关键因素之一,通过体外实验我们发现,当CD4:CD8比例介于40%~60%之间时,可以获得对靶细胞的高效杀伤,而由于患者接受化疗药物等,其CD4:CD8细胞比例常常偏离上述范围,对其临床疗效的发挥影响巨大。相应的检测结果见图12所示。其中,CD4:CD8=10%:90%的结果与CD4:CD8=0%:100%的结果类似;CD4:CD8=90%:10%的结果与CD4:CD8=100%:0%的结果类似,这两个结果未在图中展示。由结果可以看出,当CD4的数量占总细胞数量的40%-60%时,杀伤效果最佳。尤其是CD4:CD8=60%:40%时,杀伤效果最好。
试验例8:CART细胞获得高的转染效率、高效扩增和合适比例是造成体内高效杀伤靶细胞和获得体内临床疗效的基础,采用本专利技术的CART细胞治疗临床入组患者,所有入组10例难治、复发的CD19阳性血液系统恶性肿瘤患者(9例B系急性淋巴细胞白血病患者和1例B系淋巴瘤患者)均在CD19-CART治疗后15天~1个月获得形态学完全缓解和分子缓解,后者经过流式细胞技术检测微量残留病(MRD)均<0.01%。其中1例患者早期死于验证的中枢神经系统细胞因子风暴,3例患者复发,其中2例患者经二次CART治疗后获得再次形态和分子缓解,平均6个月的无复发生存率(RFS)且经过1年的临床观察,入组患者的无事件生存率为52.5%。除上述1例患者死于早期中枢神经系统细胞因子风暴外,3例复发患者中1例死于后期化疗相关的感染,8例患者存活,且骨髓形态学和MRD检测均处于缓解状态,没有原发病存在依据,总生存率达到77.14%,结果如图13和图14所示。
以上所述仅是本发明的较佳实施例而已,并非对本发明作任何形式上的限制,任何熟悉本专利的技术人员在不脱离本发明技术方案范围内,当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例,但凡是未脱离本发明技术方案的内容,依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰,均仍属于本发明方案的范围内。
