Description
技术领域
本发明涉及免疫细胞培养和刺激领域,具体涉及含膜整合型融合蛋白、含有该融合蛋白的细胞及其用途。
背景技术
近年来随着将免疫细胞转化为治疗手段的技术的发展,免疫细胞治疗已经显著地改变了当前的癌症治疗模式。自然杀伤细胞(NK细胞)是先天免疫系统的重要组成部分,对人体免疫能力起着关键的调节作用,并表现出强大的肿瘤细胞溶解功能。与T细胞不同,NK细胞具有天然杀伤细胞毒性,无需激活或抗原递呈,即可通过识别非自我方式启动清除肿瘤细胞、细菌等异己成分。
自然杀伤细胞(NK)在癌症过继免疫治疗中是一种很有前途的癌症治疗方法,引起了广泛的关注,其抗肿瘤功能也被大量临床试验证实。但是NK细胞大规模GMP级体外扩增方法的缺乏仍是限制其临床应用的主要因素。NK细胞在外周血单个核细胞中占比较低(1-32.6%),研究人员已经开发出多种方法来提高NK细胞的体外扩增数量和抗肿瘤功能。这些方法包括使用细胞因子和抗体来刺激NK细胞的扩增,但是扩增倍数非常有限,也包括使用饲养层细胞进行NK细胞的扩增,扩增倍数最高报道如【Denman CJ,Senyukov VV,SomanchiSS,Phatarpekar PV,Kopp LM,et al.(2012)Membrane-Bound IL-21Promotes SustainedEx Vivo Proliferation of Human Natural Killer Cells.PLoS ONE 7(1):e30264.doi:10.1371/journal.pone.0030264】文献所述Clone 9.mbIL21滋养层细胞三周时间可激活NK细胞平均扩增47967倍(中位数为31,747)。
RetroNectin是重组人纤维连接蛋白(FN)的片断,包括细胞结合域,肝素结合域Ⅱ和CS1位点三个功能区域。不仅可以增强病毒的感染效率,还可以刺激淋巴细胞,使其获得上千倍的增殖。但至今没有人报道RetroNectin或其片段对NK增殖的报道。

具体实施方式
本发明公开了一种可以刺激免疫细胞体外大量扩增的饲养层细胞,其膜上整合有含FN片段与细胞因子的融合蛋白。本文的饲养层细胞可使NK细胞24天体外扩增20万倍以上,为NK细胞作为通用型细胞治疗产品提供了非常高效的工具。本发明方法制备的NK细胞具有更高的肿瘤细胞杀伤能力和细胞因子分泌量。本发明饲养层细胞的膜上整合有融合蛋白,该融合蛋白包含与整合域以及与其融合的细胞因子。
本文中,膜“整合”与膜“结合”不同。膜结合通常指分子通过与跨膜蛋白、跨膜区或膜蛋白的共价连接而结合在细胞膜磷脂双分子之间的过程。而膜整合是通过整合结构域与整合素进行配体受体整合而固定到细胞表面。发明人发现,想要实现有效的膜整合,整合域需要FN肝素结合区域Ⅱ的受体与CS-1功能区域的VLA-4整合受体协同发挥最大整合优势。
因此,本发明还提供一种膜整合的融合蛋白,包含整合域以及与其融合的功能多肽,所述整合域包含FN的肝素结合域Ⅱ和CS1结合域。所述功能多肽可以是任何需要固定在膜上的多肽分子,例如细胞因子、肿瘤相关蛋白、病毒蛋白。
根据上述发现,为了使饲养层细胞可以激活待培养的细胞(例如NK细胞)而无需添加额外的细胞因子,发明人利用上述膜整合型融合蛋白将细胞因子整合在饲养层细胞的膜上。发明人发现,整合型膜表面表达细胞因子对免疫细胞的刺激比膜结合型细胞因子和游离细胞因子更强。
本文中,细胞因子通过与整合域偶联而整合在细胞膜表面。整合域包含FN(纤维连接蛋白)的肝素结合域Ⅱ和/或CS1结合域,任选还包含FN的细胞结合域。优选地,整合域位于细胞因子的N端方向。在一个或多个实施方案中,整合域具有SEQ ID NO:2所示的序列或与其具有至少90%序列相同性的变体。整合域和细胞因子之间具有间隔区(接头或铰链)。通常,间隔区的长度为10-70aa,优选12-66aa,例如为12aa、54aa、55aa或66aa或由上述任两个数字之间的范围。间隔区可以包含接头,例如由G和/或S组成的多肽序列,例如GS、GSG、GSSG、SGS、GGGGS的重复n次(如3次)的多肽。示例性接头具有SEQ ID NO:3所示序列,或与其具有至少90%序列相同性的序列。

形成本文多肽的上述各部分,如信号肽、FN的肝素结合域Ⅱ、CS1结合域、细胞因子、铰链区、跨膜区和胞内信号区等,相互之间可直接连接,或者可通过本领域周知的接头序列连接,例如前文所述的含G和S的接头序列。
本发明的多肽可以是重组多肽、合成多肽。本发明的多肽可以是化学合成的产物,或使用重组技术从原核或真核宿主(例如,细菌、酵母、植物)中产生。根据重组生产方案所用的宿主,本发明的多肽可以是糖基化的,或可以是非糖基化的。本发明的多肽还可包括或不包括起始的甲硫氨酸残基。
本发明还包括所述多肽或结构域的片段、衍生物和类似物。如本文所用,术语“片段”、“衍生物”和“类似物”是指基本上保持所述多肽相同的生物学功能或活性的多肽。
多肽或结构域的片段、衍生物或类似物可以是(i)有一个或多个保守或非保守性氨基酸残基(优选保守性氨基酸残基)被取代的多肽或结构域,而这样的取代的氨基酸残基可以是也可以不是由遗传密码编码的,或(ii)在一个或多个氨基酸残基中具有取代基团的多肽或结构域,或(iii)成熟多肽或结构域与另一个化合物(比如延长多肽半衰期的化合物,例如聚乙二醇)融合所形成的多肽,或(iv)附加的氨基酸序列融合到此多肽或结构域序列而形成的多肽(如前导序列或分泌序列或用来纯化此多肽的序列或蛋白原序列,或与抗原IgG片段的形成的融合蛋白)。根据本文的教导,这些片段、衍生物和类似物属于本领域熟练技术人员公知的范围。
术语“变体”或“突变体”是指与参照序列相比,通过一个或多个氨基酸的插入、缺失或取代使氨基酸序列发生变化但保留至少一种生物活性的肽或多肽。本文任一实施方案所述的突变体包括与参照序列(如本文所述的SEQ ID NO:1-8所编码的氨基酸序列)具有至少70%,优选至少80%,优选至少85%,优选至少90%,优选至少95%,优选至少97%的序列相同性并保留参照序列的生物学活性(如作为嵌合抗原受体、表面细胞因子表达蛋白、信号转换受体)的氨基酸序列。可采用例如NCBI的BLASTp计算两条比对的序列之间的序列相同性。突变体还包括在参照序列的氨基酸序列中具有一个或多个突变(插入、缺失或取代)、同时仍保留参照序列生物学活性的氨基酸序列。所述多个突变通常指1-10个以内,例如1-8个、1-5个或1-3个。取代优选是保守性取代。例如,在本领域中,用性能相近或相似的氨基酸进行保守性取代时,通常不会改变蛋白质或多肽的功能。“性能相近或相似的氨基酸”包括例如,具有相似侧链的氨基酸残基的家族,这些家族包括具有碱性侧链的氨基酸(例如赖氨酸、精氨酸、组氨酸)、具有酸性侧链的氨基酸(例如天冬氨酸、谷氨酸)、具有不带电荷的极性侧链的氨基酸(例如甘氨酸、天冬酰胺、谷氨酰胺、丝氨酸、苏氨酸、酪氨酸、半胱氨酸)、具有非极性侧链的氨基酸(例如丙氨酸、缬氨酸、亮氨酸、异亮氨酸脯氨酸、苯丙氨酸、甲硫氨酸、色氨酸)、具有β-分支侧链的氨基酸(例如苏氨酸、缬氨酸、异亮氨酸)和具有芳香侧链的氨基酸(例如酪氨酸、苯丙氨酸、色氨酸、组氨酸)。因此,在本发明多肽中用来自同一侧链类的另一氨基酸残基替换一个或几个位点,将不会在实质上影响其活性。
多肽或结构域的截短变体也可以用于本发明,只要该变体基本上保持与多肽或结构域相同的生物学功能或活性,例如保持整合域的膜整合功能的FN肝素结合域Ⅱ和CS1结合域的截短变体。
本文所述多肽可以是经过修饰的多肽。修饰(通常不改变一级结构)形式包括:体内或体外的多肽的化学衍生形式如乙酰化或羧基化。修饰还包括糖基化,如那些在多肽的合成和加工中或进一步加工步骤中进行糖基化修饰而产生的多肽。这种修饰可以通过将多肽暴露于进行糖基化的酶(如哺乳动物的糖基化酶或去糖基化酶)而完成。修饰形式还包括具有磷酸化氨基酸残基(如磷酸酪氨酸,磷酸丝氨酸,磷酸苏氨酸)的序列。还包括被修饰从而提高了其抗蛋白水解性能或优化了溶解性能的多肽。

编码成熟多肽的核酸分子包括:只编码成熟多肽的编码序列;成熟多肽的编码序列和各种附加编码序列;成熟多肽的编码序列(和任选的附加编码序列)以及非编码序列。术语“编码多肽的核酸分子”可以是包括编码此多肽的核酸分子,也可以是还包括附加编码和/或非编码序列的核酸分子。
本发明的核酸分子可以是多肽或结构域的编码序列,或者是多肽或结构域的表达框。本文中,编码序列指核酸序列中直接确定其蛋白产物(例如信号肽、整合域、铰链区、跨膜区、胞内信号区或细胞因子蛋白)的氨基酸序列的部分。编码序列的边界通常是由紧邻mRNA 5’端开放读码框上游的核糖体结合位点(对于原核细胞)和紧邻mRNA 3’端开放读码框下游的转录终止序列确定。编码序列可以包括,但不限于DNA、cDNA和重组核酸序列。本文中,表达框指表达感兴趣基因所需的完整元件,包括启动子、基因编码序列和PolyA加尾信号序列。在某些实施方案中,所述编码序列或表达框整合到细胞的基因组中。因此,在这些实施方案中,本文所述的细胞的基因组中稳定整合了包含编码本文所述多肽的表达框。
本发明还涉及上述核酸分子的变异体,其编码与本发明有相同的氨基酸序列的多肽或多肽的片段、类似物和衍生物。此多核苷酸的变异体可以是天然发生的等位变异体或非天然发生的变异体。这些核苷酸变异体包括取代变异体、缺失变异体和插入变异体。如本领域所知的,等位变异体是一个多核苷酸的替换形式,它可能是一个或多个核苷酸的取代、缺失或插入,但不会从实质上改变其编码的多肽的功能。
本发明还涉及与上述的序列杂交且两个序列之间具有至少50%,较佳地至少70%,更佳地至少80%、85%、90%、95%相同性的多核苷酸。本发明特别涉及在严格条件(或严紧条件)下与本发明所述多核苷酸可杂交的多核苷酸。在本发明中,“严格条件”是指:(1)在较低离子强度和较高温度下的杂交和洗脱,如0.2×SSC,0.1%SDS,60℃;或(2)杂交时加有变性剂,如50%(v/v)甲酰胺,0.1%小牛血清/0.1%Ficoll,42℃等;或(3)仅在两条序列之间的相同性至少在90%以上,更好是95%以上时才发生杂交。

10)饲养层细胞GFP-mbIL21表征流式检测结果如图5所示,GFP-mbIL21阳性细胞占比分为93.3%。
11)饲养层细胞CS1-IL21、HBD-IL21流式未检测到膜整合的IL-21信号,检测结果分别如图6、图7所示,几乎检测不到IL21阳性细胞。因此,整合域需要FN肝素结合区域Ⅱ的受体与CS-1功能区域的VLA-4整合受体协同发挥最大整合优势。
实施例2:NK细胞分离
单个核细胞分离与冻存
将采集的脐带血或者健康人单采血核对信息后进行单个核细胞分离。
血液颠倒混匀后,用浸泡70%乙醇的棉球擦拭转移导管,然后用剪刀剪开,将脐带血或者单采血平均倒入50ml离心管中,室温1500g离心10min(降速为4)。离心过程中,将样本密度分离液分出15ml/管于新的50ml离心管中。离心结束后用移液管吸取上层血浆,转移至新的50ml离心管中,分离得到的血浆于56℃进行灭活30min;然后1500g离心10min后取上清并于-20℃冰箱储存备用。
离心下来血细胞用氯化钠注射液稀释,血细胞:氯化钠注射液(V/V)=1:1,用移液管吹打混匀;用25ml规格的移液管向每支装有样本密度分离液离心管中慢慢加入上述稀释的血细胞,注意不要冲破界面(方法:将离心管倾斜45°,在样本密度分离液液面上0.5cm处,缓慢注入稀释的血细胞,不要打乱液面界面。将离心机升降速均调为0,室温850g离心20min。离心结束后,取出离心管,可见管内液体有分层,用10ml移液管吸弃上层,再缓慢吸取白细胞层,合并至新的50ml离心管中,结束后每支离心管补氯化钠注射液至50ml,进行第一次洗涤:上下颠倒混匀后,室温700g,离心5min。
观察沉淀,弃上清,指弹混匀细胞,用10ml移液管每管加10ml氯化钠注射液重悬细胞,再补至50ml,进行第二次洗涤:混匀后,室温450g,离心6min。离心结束弃上清,加入10ml氯化钠注射液重悬,将细胞合并至一支50ml离心管中,补氯化钠注射液至50ml,混匀后,取10-20μl计数,其余细胞进行第三次洗涤:室温300g,离心8min。
离心结束后,观察细胞沉淀有无洗涤干净,若红细胞污染严重,则需进行红细胞裂解操作:轻柔弃干净上清,根据上一步骤的计数结果,每1×108个总细胞用90~110μl红细胞裂解液重悬混匀,室温放置裂解10分钟,裂解完成后加入氯化钠注射液补至50ml,混匀室温450g,离心6min。离心前取10-20μl计数;将取出的细胞悬液与0.1%台盼蓝按照1:1混合,然后取出计数板,往加样槽中加入20ul混悬液,待细胞沉降数秒后打开软件开始计数并记录结果。
根据计数结果进行细胞灌装:吸弃上清(注意将上清完全吸弃),用自制冻存液将细胞沉淀重悬,调整细胞密度为1×108个活细胞/ml后分装,每支1mL。放置程序降温仪冻存结束转移至液氮罐长期保存。
单个核细胞中NK细胞分离
NK细胞分离是使用美天旎NK分选试剂盒(NK isolation kit,human,130-092-657),具体操作流式如下:
将冻存的PBMC或者CBMC细胞放37°水浴锅速溶2-3min后,转入离心管中,300g离心5min,弃上清,加入适量缓冲液重悬,取20μL细胞悬液,加入20μL 0.1%台盼蓝进行计数,记录活细胞密度与细胞活率。根据细胞悬液体积,计数出细胞总数。按照每107cells加入40μLBuffer,10μL NK Cell Biotin-Antibody Cocktail,混匀后(2-8℃)冰箱孵育5min。之后,每107cells直接加入30μL buffer,加入20μL of NK Cell MicroBeads Cocktail,混匀后(2-8℃)冰箱孵育10min。10min中后,使用buffer补足体积至500μL。放置LS柱子至磁力架上,15mL离心管放置于LS柱子下方,使用3mL Buffer冲洗一次。等冲洗Buffer完全滴完,LS柱子下方换新离心管,加入细胞磁珠混合悬液至LS柱子中,收集未标记的细胞,即NK细胞。
接收的NK细胞悬液混匀后,取20μL细胞悬液,加入20μL 0.1%台盼蓝进行计数,记录活细胞密度与细胞活率。根据细胞悬液体积,计数出细胞总数。
实施例3:NK细胞扩增
根据NK细胞的计数结果以及流式检测分选后NK细胞CD56+细胞比例,算出起始细胞中NK细胞的数量。按照NK:FC=1:2(或者其它比例)加入对应量的NK细胞与100Gy辐照后饲养层细胞(FC,Feeder cell),混匀后用完全培养基(SCGM+10%FBS+200IU/mL IL-2、或者SCGM+10%FBS+200IU/mL IL-2+20ng/mL rhIL-21)将总细胞密度调为2.5×106/mL左右,放于合适的培养容器中进行培养。培养的第三天、第五天进行换液,第七天或者第八天计数并计算第一轮扩增倍数。第七天或者第八天以同样方式开始第二轮培养,第15或16天按照除NK:FC=1:1外同样方式进行第三轮培养,培养周期为21-24天。
饲养层细胞K562-CD86-41BBL、K562-CD86-41BBL+20ng/mL sIL-21、K562-CD86-41BBL+Retronectin coating、FN21、FN-mbIL21与GFP-mbIL21刺激NK细胞扩增两轮共14天扩增倍数比较如图8所示,
饲养层细胞若只表达CD86+41BBL,D14天细胞平均扩增倍数仅为598.6,添加rhIL-21,或者将细胞加入Retronectin包被的培养皿中,NK细胞扩增倍数上升1倍,但统计学上无明显差异。
若饲养层细胞FN21表面表达融合蛋白FN1 heparin binding domain-CS1-IL-21,NK扩增倍数D14可达3450倍,且与FN-mbIL21(2764)无显著差异(n=5),说明整合型FN21对NK的扩增效果显著。
接着用FN21、FN-mbIL21与GFP-mbIL21刺激NK扩增3轮,共24天,扩增曲线如图9所示,FN21平均扩增倍数可达239994.95,优于FN-mbIL21(125572)与GFP-mbIL21(131121)将近2倍。

实施例5:NK细胞表型检测
培养至D14细胞,取总活细胞数为5E5的细胞悬液用SONY SA3800流式细胞仪进行NK细胞(CD56+细胞)表面标志物比例的检测,包括NK激活型受体NCRs(NKp30/NKp44/NKp46)、肿瘤识别位点NKG2D、抑制性受体NKG2A、KIRs(CD158a/h/g),介导ADCC受体CD16(见纯度检测方法),具体操作流程如下:

实施例6:NK细胞功能检测
1.NK细胞脱颗粒功能CD107a检测
相关研究表明,在无靶细胞情况下,NK细胞膜表面溶酶体相关膜蛋白1(CD107a)表达量很低,几乎检测不到,但是当NK细胞杀伤靶细胞时,CD107a是会随着细胞毒性颗粒转运到细胞膜表面,可通过流式细胞术检测到细胞表面CD107a表达量的增加,因此,刺激后NK细胞表面CD107a表达量高低可反映NK细胞毒杀伤活性水平,具体检测流程如下所述:
1)实验设置本底组(只有NK细胞)和实验组(NK细胞+靶细胞),本试验中NK细胞和靶细胞使用量均为4×105个活细胞/孔。NK细胞分别来自4个供者,靶细胞为K562。
2)配制CD107a工作液:取适量细胞完全培养基(RPMI1640+10%FBS)按照1:100比例加入PE-anti-human CD107a(eBioscience,12-1079-42),按照1:1000比例加入GolgiStop Inhibitor(BD Bioscience,51-2092KZ)
3)将本底组(4×105个NK细胞)和实验组(4×105个NK细胞+4×105个靶细胞)离心后用100μL CD107a工作液重悬,加入到V底96孔板中
4)将各组细胞置于37℃,5%CO2培养箱中共孵育4小时后,将实验组和本底组细胞分别转移至对应的流式管中,450±50g离心5min。加入PE/Cy7anti-human CD56(NCAM)Antibody(BioLegend,318318)标记,流式检测CD56+NK细胞表面CD107a表达量比例。
5)结果如图12所示:饲养层细胞FN21、FN-mbIL21与GFP-mbIL21刺激产生的NK遇到靶细胞K562时,产生CD107a的比例分别为64.2%、63.4%、56.9%
2.NK细胞因子IFN-γ分泌量检测
NK细胞遇到靶细胞时,细胞因子分泌量也会增加,IFN-γ分泌可以抑制肿瘤细胞的增殖。NK与靶细胞孵育时,加入蛋白转运抑制剂布雷菲德菌素A(BFA)(GolgiPlug),可使IFN-γ在高尔基体的累积,提高流式检测细胞因子分泌细胞的能力。细胞内因子流式细胞术检测流程如下所述:
1)实验设置本底组(只有NK细胞)和实验组(NK细胞+靶细胞),本试验中NK细胞和靶细胞使用量均为4×105个活细胞/孔。NK细胞分别来自4个供者,靶细胞为K562。
2)配制GolgiPlug重悬工作液:取适量细胞完全培养基(RPMI1640+10%FBS)按照1:1000比例加入GolgiPlug Inhibitor(BD Bioscience,51-2301KZ)
3)将本底组(4×105个NK细胞)和实验组(4×105个NK细胞+4×105个靶细胞)离心后用100μLGolgiPlug工作液重悬,加入到V底96孔板中
4)将各组细胞置于37℃,5%CO2培养箱中共孵育4小时后,将实验组和本底组细胞分别转移至对应的流式管中,450±50g离心5min。加入PE/Cy7anti-human CD56(NCAM)Antibody(BioLegend,318318)标记30min
5)细胞固定:每管加入固定液BD Fixation/Permeabilization solution(BD,51-2090KZ)200μL,混匀,4℃破膜20min。
6)细胞通透:将10x BD Perm/WashTM Buffer(BD,51-2091KZ)用ddH2O配制1x BDPerm/WashTM Buffer,每管加入约1mL左右1xBD Perm/WashTM Buffer;室温通透10min;450±50g离心5min,吸弃上清。
7)细胞内因子染色:用1x BD Perm/WashTM Buffer按照1:100比例配制IFN-γ(Human IFN-r(gamma)PE,BD,554701)染色工作液,
8)每管流式管中加入抗体工作液100μL/管,混匀后放置2-8℃避光孵育,染色30min。
9)染色结束后,加入1ml的1x BD Perm/WashTM Buffer进行洗涤,450±50g离心5min;
10)吸弃上清,加入200μL PBS缓冲液重悬细胞,流式上机检测细胞内IFN-γ聚集量。
6)检测结果如图13所示:饲养层细胞FN21、FN-mbIL21与GFP-mbIL21刺激产生的NK遇到靶细胞K562时,产生细胞因子的比例分别为32.2%、26.2%、16.4%。
3.NK细胞杀伤功能检测(基于Luciferase杀伤检测)
荧光素酶报告基因Luciferase报告基因系统是以荧光素(luciferin)为底物来检测萤火虫荧光素酶(fire fly luciferase)活性的一种报告系统。荧光素酶可以催化luciferin氧化成oxyluciferin,在luciferin氧化的过程中,会发出生物荧光(bioluminescence)。然后可以通过荧光测定仪也称化学发光仪(luminometer)或液闪测定仪测定luciferin氧化过程中释放的生物荧光。荧光素和荧光素酶这一生物发光体系,可以极其灵敏、高效地检测细胞死活与基因表达。在靶细胞中稳定表达Luciferase-GFP基因(GFP与Luciferase共用启动子,可作为Luciferase表达参照物),当所有细胞是活细胞状态时,加入荧光素(luciferin)后,可用化学发光仪检测检测到整体荧光值的大小。当一部分细胞被NK细胞杀伤后,Luciferase不再表达,荧光值会随着活细胞比例下降而下降,所以可以用Luciferase报告基因系统来定量NK细胞的杀伤能力。具体操作步骤如下:
1)实验设置对照组(3×104个靶细胞)和实验组(不同效靶比E:T=10:1,5:1,2.5:1,1.25:1,0.625:1,0.31:1,0.16:1)本试验中效应细胞为NK细胞分别来自4个供者,靶细胞为K562-Luciferase-GFP。
2)取出效靶细胞,先对细胞进行镜检,观察细胞状态,另用移液管轻轻混匀从中取20μL细胞加20μL 0.1%台盼蓝1:1混匀,进行计数,记录下计数的结果
3)靶细胞K562-Luci-GFP的取用:根据实验设计,靶细胞每孔3×104个,每孔50μL,取相应体积细胞悬液,450±50g离心5min,吸弃上清;用适量新鲜完全培养基将靶细胞重悬,密度调整为6×105cells/mL。
4)效应细胞的取用:根据实验设计,按照两倍梯度稀释法,效应细胞第一排10:1孔需6×105个活细胞,共设2个复孔,共1.2×106个活细胞,取相应体积细胞悬液,450±50g离心5min,吸弃上清;按照每孔100μL,共2个孔,用200μL新鲜完全培养基将靶细胞重悬,密度调整为6×106cells/mL。
5)取一块不透光酶标板,实验组中除第一排10:1孔外,其余均加入50μL新鲜培养基,本底组加入50μL新鲜培养基。
6)效应细胞的梯度稀释:取重悬后的效应细胞悬液100μL,用排枪加入第一排10:1两个孔中,从第一排10:1孔取50μL加入第二排5:1孔中,直至第七个孔,多余50μL弃掉。
7)效应细胞与靶细胞的混合:所有孔每孔依次加入50μL密度为6×105cells/mL的靶细胞,第一排补50μL完全培养基,即效应细胞与靶细胞总体积为100μL/孔,加入后,轻轻混匀,37℃共孵育4h。
8)培养结束后,将细胞从CO2培养箱取出,向标记好的每孔中依次加入100μL荧光素底物(Bright-Glo萤光素酶检测系统,Promega,E2620),反应3-5min,在酶标仪(PerkinELmer,VICTOR NIVO 3F)进行荧光读数检测。
9)数据分析方法:杀伤效率=(1-实验组样品读数平均值/本底组样品读数平均值)*100%
10)杀伤曲线图详见图14,饲养层细胞FN21、FN-mbIL21与GFP-mbIL21刺激产生的NK遇到靶细胞K562-luc-GFP时,杀伤效果相当。
