Description

含有热休克蛋白gp96的多肽、药物组合物和用途
技术领域
本发明属于生物医药领域,涉及一种含有热休克蛋白gp96的多肽、药物组合物和用途。
背景技术
调节性T细胞(Treg)在维持免疫稳态中发挥着关键作用,其中转录因子Foxp3决定了Treg细胞的发育和功能。foxp3基因缺陷可诱导人体Treg细胞功能障碍,从而导致免疫失调、多内分泌病、肠病和X染色体连锁综合征等一系列疾病的发生。Treg细胞功能缺陷或exTreg细胞发育与自身免疫性疾病呈正相关,如系统性红斑狼疮(SLE)、多发性硬化症(MS)、强直性脊柱炎(AS)等。
热休克蛋白(Heat shock protein,HSP)是一类在生物进化中高度保守且广泛存在于原核及真核生物中的蛋白质。HSP根据同源程度及分子量大小可分为HSP110、HSP90、HSP70、HSP60、HSP40、小分子HSP及泛素等多个亚家族。人类热休克蛋白90家族(HSP90)包括HSP90α,HSP90β,gp96(grp94)和Trap-1四个成员。gp96(GRP94)为内质网HSP90家族的代表,与细胞质HSP90高度同源,主要生物学功能有:分子伴侣,参与新合成蛋白的折叠与组装;与细胞内的其他肽类蛋白质尤其是变性蛋白的结合,参与细胞的抗损伤、修复和热耐受过程;参与蛋白质水解过程;结合抗原肽,加工提呈肿瘤抗原及维持细胞内环境稳定等作用;对细胞的生长、发育、分化及死亡具有一定的调节作用。
gp96由于具有显著的生物学活性,特别是在免疫学方面同时具有刺激特异性杀伤T细胞的作用和抑制调节T细胞的作用。研究表明,gp96可以通过调节性T细胞(Treg)和CD14+HLA-DR-/low抑制体内的免疫反应。这为治疗自身免疫类疾病提供了新的思路。然而,gp96的免疫学功能却有待进一步提高。
发明内容
本发明人经过深入的研究和创造性的劳动,得到了一种分离的多肽。进一步地,所述分离的多肽形成二聚体形式的蛋白。本发明人惊奇地发现,该多肽或蛋白能够显著地提高gp96蛋白的生物学活性特别是免疫学功能。这对于靶向调节性T细胞的功能具有很大的提升,从而适合自身免疫性疾病的治疗,具有重要的临床应用价值。由此提供了下述发明:

B——A
式I;
其中:

实施例1:gp96-plus1-4蛋白的制备
1、重组质粒的构建
将热休克蛋白gp96(SEQ ID NO:1)的N端分别与4个不同长度的片段(SEQ ID NOs:3-6)经人工碱基合成串联连接在一起(金斯瑞生物科技股份有限公司),再将目的片段连接至昆虫细胞表达载体Pfastbac1中,构建重组表达载体,命名为Pfastbac1-gp96-plus。将重组载体分别转化至DH10BacTM感受态细胞,经重组筛选得到重组杆粒DNA。在以上各蛋白的C端添加6xHis标签。
2、gp96-plus蛋白的表达
2.1将重组杆粒DNA转染贴壁Sf9细胞(每8×105个Sf9细胞约转染2μg重组质粒;转染过程中,转染试剂为CellfectinIIreagent(购自Lifetechnologies,产品目录号:10362-100)),27℃孵育72h,离心,上清液即为P1代病毒。
2.2将Sf9细胞悬浮液1(含8×106个Sf9细胞)27℃培养1~5h,得到贴壁培养细胞;然后向所述贴壁培养细胞中加入P1代病毒(剂量为0.05~0.1MOI),27℃孵育72h,4000rpm离心5min,上清液即为P2代病毒。
2.3向Sf9细胞悬浮液2(含8×106个Sf9细胞)中加入P2代病毒(剂量为0.05~0.1MOI),27℃、100~120rpm培养72h,4000rpm离心5min,上清液即为P3代病毒。
3、gp96-plus蛋白的纯化。
3.1向300ml的Sf9细胞悬浮液3(含Sf9细胞2~4×106个/ml)中加入P3代病毒(剂量为0.05MOI),27℃、100~120rpm培养72~96h,得到悬浮液。
3.2取所述悬浮液,7000rpm离心20min,获得上清液。
3.3取所述上清液,经0.22mm滤膜过滤,获得上样液。
3.4将所述上样液上样于Ni亲和层析柱。上样流速控制在1ml/min,然后用不含咪唑的Tris-HCl缓冲液冲洗,再用含有咪唑的Tris-HCl缓冲液洗脱并收获洗脱液。将洗脱液用截留分子量为50KD的超滤管进行超滤换液得到重组gp96-plus蛋白置换液。
3.5将所述置换液上样于HiTrap-QSepharose离子交换层析柱(流速为1ml/min),然后先用5ml的pH7.5、200mM的PBS缓冲液冲洗(流速为1ml/min);再用10ml的pH7.5、300mM的PBS缓冲液冲洗(流速为1ml/min);最后用3ml的pH7.5、600mM的PBS缓冲液冲洗(流速为1ml/min),收集过柱后溶液并采用截留分子量为50KD的超滤管进行超滤浓缩,得到1ml左右的浓缩液。所述浓缩液即含有重组热休克蛋白gp96,分别命名为gp96-plus1至gp96-plus4。采用BCA法测定蛋白溶液中的蛋白浓度,最后分装,蛋白浓度为1mg/ml,贮存于-80℃。gp96-plus1至gp96-plus4用于下面的实验。
4、非还原SDS-PAGE电泳分析
将gp96-plus1-4蛋白和全长gp96的溶液进行非还原SDS-PAGE电泳分析,实验结果见图1。
结果表明,gp96的溶液在分子量96kDa位置显示条带,gp96-plus1-4溶液在分子量190kDa位置显示条带,说明gp96-plus1-4四种蛋白为二聚体形式。蛋白纯度大于95%。
实施例2:gp96-plus1-4蛋白诱导小鼠调节性T细胞活性的评价
本实施例考察单独gp96蛋白(SEQ ID NO:1)、gp96-plus1(gp96与多肽片段1连接,SEQ ID NO:11)、gp96-plus2(gp96与多肽片段2连接,SEQ ID NO:12)、gp96-plus3(gp96与多肽片段3连接,SEQ ID NO:13)、gp96-plus4(gp96与多肽片段4连接,SEQ ID NO:14)蛋白诱导小鼠产生调节性T细胞的情况。
1、小鼠分组免疫
将30只六周龄体重为14~16g的C57BL/6小鼠(购自北京维通利华实验动物技术有限公司)随机分成gp96处理组、gp96-plus1处理组、gp96-plus2处理组、gp96-plus3处理组、gp96-plus4处理组和对照组(每组5只小鼠),分别进行如下处理:
gp96-plus1处理组至gp96-plus4处理组:小鼠生长至第9周龄,腹部皮下分别注射实施例1制备获得的经纯化的gp96-plus1、gp96-plus2、gp96-plus3、gp96-plus4的溶液,记为实验第1天;实验第8天后,再次腹部皮下注射实施例1制备获得的经纯化的gp96-plus1的溶液;实验第22天,再次腹部皮下分别注射实施例1制备获得的经纯化的gp96-plus1、gp96-plus2、gp96-plus3、gp96-plus4的溶液。每次注射剂量分别为100μg、300μg和500μg蛋白/只小鼠。
gp96处理组:小鼠生长至第9周龄,腹部皮下注射实施例1制备的经纯化的gp96,记为实验第1天;实验第8天后,再次腹部皮下注射实施例1制备的经纯化的gp96的溶液;实验第22天,再次腹部皮下注射实施例1制备的全长gp96的溶液。每次注射剂量为100μg、300μg和500μg gp96蛋白/只小鼠。
对照组:实验第1天腹部皮下注射pH7.2、0.01mol/LPBS缓冲液,实验第8天,再次腹部皮下注射pH7.2、0.01mol/LPBS缓冲液;实验第22天,再次腹部皮下注射pH7.2、0.01mol/LPBS缓冲液。每次注射PBS剂量均为100μl/只、300μg/只或500μl/只。
2、免疫效果评价
在第25天处死小鼠,取小鼠脾脏分离制备小鼠脾脏淋巴细胞,利用流式细胞仪分析小鼠的调节性T细胞(Tregs)百分比(%CD3+CD4+CD25+Foxp3+Tregs/CD3+CD4+T细胞)。调节性T细胞的分离和检测方法详见XinghuiLi,etal.2013.InductionofregulatoryTcellsbyhigh-dosegp96supp ressesmurineliverimmunehyperactivation.PLoSOne.8(7):e68997。
结果如图2A至图2C所示。
结果显示,gp96和gp96-plus蛋白免疫小鼠后的调节性T细胞(Tregs)百分比。结果表明,gp96-plus1、gp96-plus2、gp96-plus3、gp96-plus4蛋白免疫组调节性T细胞水平明显高于gp96免疫组(P<0.0001),而且gp96-plus3、gp96-plus4蛋白高于gp96-plus1、gp96-plus2蛋白处理小鼠的调节性T细胞百分比。
结果还显示,注射剂量100μg和500μg gp96-plus的小鼠的调节性T细胞水平也明显高于gp96治疗组,说明注射剂量/只小鼠为100μg、300μg或500μg gp96-plus对小鼠调节性T细胞增加效果相对于gp96均有明显的提高;300μg的效果优于100μg,但是500μg和300μg的结果接近。

2、抗双链DNA抗体滴度的分析
血清中抗双链DNA抗体的水平采用酶联免疫吸附(ELISA)方法测定,步骤如下:
2.1向96孔酶标板(购自Nunc,RochesterNY,USA)中加入2.5μg/ml的小牛胸腺dsDNA标准品(购自SigmaAldrich,USA,货号:D8899-1MG),每孔100μl。4℃包被过夜。
2.2加入2%牛血清白蛋白(购自Invitrogen,USA)100μl,37℃孵育60分钟。
2.3加入血清样本50μl(1:50比例稀释)和抗dsDNA抗体标准品(购自ChemiconInternational,USA,clone号:16-13),37℃孵育60分钟。
2.4弃去孔内液体,每孔加入200μl的1×洗涤液(PBST,PBS按0.1%加入Triton-X100),静置30秒,甩干,重复洗涤5次。最后在吸水纸上拍干。
2.5加入HRP标记的抗小鼠二抗(购自中杉金桥,1:5000稀释),每孔50μl。37℃孵育60分钟。
2.6弃去孔内液体,每孔加入200μl的1×洗涤液,静置30秒,甩干,重复洗涤5次。最后在吸水纸上拍干。
2.7每孔加入100μl底物(1×TMBELISASubstrateSolution,购自eBioscience,货号:00-4201-56)。37℃孵育15分钟。
2.8弃去孔内液体,每孔加入50μl终止液(2MH2SO4),混匀,酶标仪上450nm波长下读数。测定应在加终止液后15分钟以内进行。
3、尿蛋白的测定
尿蛋白检测试剂盒购自南京建成生物工程研究所(货号:C035-2)
3.1取三个管,分别标记为空白管,标准管和测定管。空白管加入双蒸水0.05ml,CBB试剂3.0ml。标准管加入563mg/L蛋白标准液0.05ml,CBB试剂3.0ml。测定管加入尿液样本0.05ml,CBB试剂3.0ml。
3.2充分混匀,放置5分钟。分光光度计用波长595nm检测各管的吸光度。
尿蛋白浓度(mg/L)=(测定OD值-空白OD值)/(标准OD值-空白OD值)×标准品浓度
4、效果评价

从最后一次免疫后的第1周开始监测小鼠血糖值,每周检测1次。取小鼠尾静脉血1滴,用血糖仪(德国罗氏公司ACCU-Performa)参照说明书测定血糖值。
2、效果评价
小鼠血糖浓度检测结果见图5。
结果显示,gp96-plus1、gp96-plus2、gp96-plus3、gp96-plus4蛋白免疫后小鼠的血糖浓度随着时间变化而逐渐降低,最终浓度显著低于对照组(PBS)(P<0.001),同时所有gp96-plus免疫组小鼠血糖水平也明显低于gp96免疫组(P<0.01)。
上述结果表明,用gp96-plus免疫小鼠,能够有效地治疗小鼠的T1D,其治疗效果优于gp96。
