Description

用于治疗癌症的、包含含有IL-2蛋白和CD80蛋白的融合蛋白 与自然杀手细胞的药物组合物
技术领域
本发明涉及一种用于治疗癌症的药物组合物,其包含作为活性成分的含有CD80蛋白及IL-2变体的融合蛋白与NK细胞。
背景技术
IL-2,亦称作T细胞生长因子(TCGF),是一种球状糖蛋白,其在淋巴细胞的生成、存活及动态平衡中发挥核心的作用。IL-2蛋白具有15.5kDa至16kDa的大小且由133个氨基酸构成。IL-2通过与具有三个不同次单元法人IL-2受体结合,介导各种免疫作用。此外,IL-2主要是由活化的T细胞合成,特别是由CD4+辅助型T细胞。IL-2会刺激T细胞的增殖与分化,及诱导细胞毒性T淋巴细胞(CTLs)的产生及外周血淋巴细胞分化成细胞毒性细胞与淋巴激素活化杀手细胞(LAK细胞)。
同时,CD80,亦称作B7-1,是膜连型蛋白B7家族的成员,其通过与其配体结合,透过递送共刺激反应及共抑制反应的方式进行免疫调节。CD80是一种表达在T细胞、B细胞、树状细胞及单核球表面上的透膜蛋白。CD80已知会与CD28、CTLA4(CD152)及PD-L1结合。CD80、CD86、CTLA4及CD28涉及共刺激-共抑制系统。例如,其等会调节T细胞的活性且涉及其增殖、分化及存活。
此外,已知自然杀手细胞(然后称NK细胞)会通过移除癌细胞而表现出抗癌活性(Loris Zamai et.al.,J.Immunol.,178:4011-4016,2007)。NK细胞活性的调节是通过各种活化性及抑制性受体传讯的平衡。已知NK细胞还能透过表达在表面上的各种免疫受体来辨别癌细胞以达到抗癌活性。由于正常细胞中存在主要组织兼容性复合体(MHC)第I类,所以正常细胞不会被NK细胞的抑制性受体辨识,从而不会遭受攻击,但癌细胞或一些受感染的细胞因MHC第I类减少或具有NK细胞活化受体的配体而会被NK细胞清除。除了癌细胞外,NK细胞还可消除癌干细胞,因此成为不仅可抑制癌的发展、增殖及转移,且可降低完全康复后癌症复发的备受关注的治疗剂来源。
发明内容
因此,研究开发安全且有效的IL-2的结果,本发明人发现共给药在一分子中含有IL-2蛋白和CD80蛋白的新穎的融合蛋白二聚体与自然杀手细胞的组合,表现出优异的抗癌作用,并完成本发明。
为达成上述目的,根据本发明的一个方面,提供一种抗癌剂,其包含作为活性成分的含有IL-2蛋白和CD80蛋白的融合蛋白二聚体与自然杀手细胞。
本发明的效果
已确认含有IL-2蛋白和CD80蛋白的融合蛋白二聚体不仅可活化免疫细胞,且当与自然杀手细胞结合给药时,可表现出协同作用。因此,此组合疗法可用于治疗癌症。
附图说明
图1是本发明中所使用的融合蛋白二聚体的实施方案的示意图。
图2显示确认所获得的融合蛋白二聚体(GI-101)的SDS-PAGE影像。
图3显示所获得的融合蛋白二聚体(GI-101)的粒径筛析色谱法(SEC)的分析。

图8显示在无自然杀手细胞的情况下单独培养K562细胞株(E/T比=0/1)时,以GI-101或CD80-Fc+Fc-IL2v2处理的癌细胞存活力结果。在此情况下,E表示作为效应细胞的NK细胞,T表示作为标靶细胞的K562癌细胞株。
图9显示在无自然杀手细胞的情况下单独培养MDA-MB-231细胞株(E/T比=0/1)时,以GI-101或CD80-Fc+Fc-IL2v2处理的癌细胞存活力结果。在此情况下中,E表示作为效应细胞的NK细胞,T表示作为标靶细胞的MDA-MB-231癌细胞株。
图10显示在无自然杀手细胞的情况下单独培养HCT-116细胞株(E/T比=0/1)时,以GI-101或CD80-Fc+Fc-IL2v2处理的癌细胞存活力结果。在此情况下,E表示作为效应细胞的NK细胞,T表示作为标靶细胞的HCT-116癌细胞株。
图11显示在无自然杀手细胞的情况下单独培养A549细胞株(E/T比=0/1)时,以GI-101或CD80-Fc+Fc-IL2v2处理的癌细胞存活力结果。在此情况下,E表示作为效应细胞的NK细胞,T表示作为标靶细胞的A549癌细胞株。
图12显示在共培养K562细胞株(标靶细胞)与自然杀手细胞(效应细胞),E/T比=1/3时,以GI-101或CD80-Fc+Fc-IL2v2的组合材料处理的癌细胞存活力结果。
在此,Y轴=0表示在起始接种时癌细胞的存活力讯号(红色讯号)范围设为0。Y轴>0是接种后发现癌细胞存活力讯号范围增加的情况,表示细胞增殖率快于细胞死亡率(细胞增殖率>细胞死亡率)。即,可视为癌细胞数增加。然而,一般认为增加的值越低,则越能抑制癌细胞的增殖。同时,假如测得的存活癌细胞面积小于起始接种时测得的存活癌细胞面积,则表示为负值,其表示细胞增殖率低于细胞死亡率(细胞增殖率<细胞死亡率)。即,与在起始接种时测得的面积相比,面积减少表示为负值。因此,提示负值越大可能不仅与癌细胞增殖的抑制有关,而且与癌细胞死亡有关。

通过腹膜内途径对癌小鼠模型给药制备实施例4中获得的mGI-101,通过静脉途径给药制备实施例3中制得的小鼠来源NK细胞。在给药当天(肿瘤移植后第6天、第10天及第13天)使用抛弃式针筒(31G,1mL)进行一次给药,共3次。针对肿瘤生长抑制模型,如以下表10所示,待给药的细胞及给药剂量四组均不同(图28)。
[表10]

实施例3:癌小鼠模型的肿瘤体积的测量
使用数字卡尺(mitutoyo,Japan)测量肿瘤的最大长度(L)及垂直宽度(W)一周二次,套用以下方程式1以计算肿瘤体积(TV)。
[方程式1]
TV(mm3)=W×W×L×0.5
使用以下方程式2计算腫瘤生長抑制百分比:
[方程式2]
肿瘤生长抑制(%)=(1-(Ti-T0)/(Vi-V0))×100
Ti=测试组于给药前的肿瘤体积
T0=测试组于给药后的肿瘤体积
Vi=对照组于给药前的肿瘤体积
V0=对照组于给药后的肿瘤体积
给药前各个体的肿瘤体积设定为分组时测量的值。
实施例4:CT26移植癌小鼠模型中肿瘤生长抑制作用的测定
实施例4.1:肿瘤体积的测量
配制准备给健康Balb/c小鼠的CT26结直肠癌细胞悬浮液(5×105细胞/0.1mL),将制得的溶液装在抛弃式针筒中,皮下给药至小鼠的右背(0.1mL/只)进行移植。在肿瘤移植后,分别给药表10中所示的药物。然后,在第10天、第13天及第17天测量肿瘤尺寸。与对照组(媒介物)相比,单独用自然杀手(NK细胞)或mGI-101治疗的组中,细胞肿瘤生长受到抑制。与对照组(媒介物)相比,用自然杀手(NK细胞)与mGI-101组合治疗的组中,细胞肿瘤生长受到抑制。与单独用自然杀手细胞或mGI-101相比,用自然杀手与mGI-101组合治疗的组中,细胞肿瘤生长受到抑制(图29)。
实施例4.2:肿瘤生长抑制分析
在实验结束(肿瘤移植后,第17天)时,计算相较于药物治疗第1天(肿瘤移植后,第10天)的肿瘤生长抑制率。对照组(媒介物)有3只小鼠具有肿瘤生长抑制30%以上,3只具有肿瘤生长抑制率50%以上及2只具有肿瘤生长抑制率80%。自然杀手细胞治疗组有6只具有肿瘤生长抑制率30%以上,5只具有肿瘤生长抑制率50%以上及2只具有肿瘤生长抑制率80%。mGI-101治疗组有5只具有肿瘤生长抑制率30%以上,5只具有肿瘤生长抑制率50%以上及1只小鼠具有肿瘤生长抑制率80%。自然杀手细胞与mGI-101组合治疗组有7只小鼠具有肿瘤生长抑制率30%以上,6只具有肿瘤生长抑制率50%以上及3只具有肿瘤生长抑制率80%(图30)。在图30中,黑长条表示肿瘤生长抑制率30%以上,浅灰色长条表示肿瘤生长抑制率50%以上及深灰色长条表示肿瘤生长抑制率80%以上。
实施例4.3:单个实验动物的肿瘤体积的测量
测定各治疗组中单个实验动物的肿瘤生长。具体地,测定对照组(媒介物)、自然杀手细胞(NK细胞)、mGI-101及自然杀手细胞+mGI-101治疗组中单个实验动物的肿瘤生长,并示于图31中。在图31中,虚线表示肿瘤尺寸为500mm3,实线表示肿瘤尺寸为250mm3
更具体地,测定对照组中单个实验动物的肿瘤生长程度并示于图32中,及测定自然杀手细胞治疗组中单个实验动物的肿瘤生长程度并示于图33中。此外,测定mGI-101治疗组中单个实验动物的肿瘤生长程度并示于图34中及测定自然杀手细胞与mGI-101组合治疗组中单个实验动物的肿瘤生长程度并示于图35中。
