Abstract
本发明提供了一种靶向CD24的胃癌治疗方法。具体地,提供了CD24抑制剂的用途,用于制备一药物组合物,所述药物组合物用于预防和/或治疗胃癌。本发明首次发现CD24抑制剂可用于治疗胃癌,从而提供了一种新的胃癌靶向治疗方法。
Description
技术领域
本发明涉及医药领域,具体涉及一种靶向CD24的胃癌治疗方法。
背景技术
胃癌是世界上第五大最常见的癌症类型,也是第三大最常见的癌症相关死亡原因,在中国等的东亚国家发病率和致死率都非常高。胃癌的发生率和死亡率与地区以及环境因素密切相关,如不良饮食、生活习惯和幽门螺杆菌感染。
早期胃癌的治疗方法包括内镜下切除、外科手术(胃切除术)、抗生素治疗根除幽门螺杆菌(Helicobacter pylori)以及辅助治疗。过去20年里,在胃癌的手术治疗、术后护理及多学科治疗方面取得了一些进步,但胃癌的预后仅稍有改善。对于治疗晚期胃癌则非常困难,这是导致胃癌高死亡率的主要原因。目前,晚期胃癌的一线治疗是基于铂类药物和5-氟尿嘧啶(5-Fu)的化学疗法。此外,曲妥珠单抗已被批准用于人类表皮生长因子受体2(HER-2)阳性胃癌患者的一线治疗。以血管内皮生长因子(VEGF)为靶标的药物ramucirumab也已被批准用于一线治疗方案失败的晚期胃癌患者。尽管有许多治疗胃癌的方法,但全世界胃癌的总生存率仅约20%。
近年来,对肿瘤免疫疗法的研究为癌症的治疗带来了新的希望和前景。但由于胃癌免疫微环境的复杂性和肿瘤异质性等原因,免疫疗法在胃癌治疗中研究仍然非常欠缺。
因此,本领域急需提供新的胃癌靶向治疗方法。
发明内容
本发明的目的是提供一种新的胃癌靶向治疗方法。
本发明第一方面,提供了一种CD24抑制剂的用途,用于制备一药物组合物,所述药物组合物用于预防和/或治疗胃癌。
在另一优选例中,所述药物组合物用于上调选自下组的细胞对肿瘤组织的浸润:CD4+T细胞、CD8+T细胞、B细胞、M1型巨噬细胞,或其组合。
在另一优选例中,所述药物组合物用于下调调节T(Treg)细胞和/或M2型巨噬细胞对肿瘤组织的浸润。
在另一优选例中,所述胃癌为对PD-1和/或PD-L1抑制剂不敏感的胃癌或对PD-1和/或PD-L1抑制剂产生抗药性的胃癌。

通用方法
流式分析:小鼠胃组织使用组织匀浆器gentleMACS Octo dissociator(MiltenyiBiotec)和1mg/mL胶原酶VI(Thermo Fisher Scientific)and 50mg/mL DNA酶I(Sigma-Aldrich)处理,分散成单细胞悬液,随后使用红细胞裂解液(BioLegend)处理。在FACS AriaII细胞仪(BD Biosciences)上采集荧光数据,并使用FlowJo软件进行数据分析。
流式抗体详细信息如下:
CD3e(145-2C11),CD11c(N418),CD11b(M1/70),CD279(PD-1;29F.1A12),F4/80(BM8),CD24(M1/69)and MHC-II(I-A/I-E;M5/114.15.2)购自BioLegend;CD4(GK1.5)和CD8a(53-6.7)购自BD Biosciences;CD45(30-F11)和Ly-6G/Ly-6C(Gr1;RB6-8C5)购自eBioscience.
免疫组化:取新鲜胃癌小鼠胃组织用4%多聚甲醛固定2小时,随后酒精梯度脱水,二甲苯透明,石蜡包埋后切片。将组织切片脱蜡并重新水化,使用苏木素和伊红(碧云天)处理组织切片,并在显微镜(Zeiss LSM 710)下观察拍照。
实施例1
幽门螺杆菌(H.felis)和N-甲基-N-的小鼠模型亚硝基脲(MNU)诱发的胃癌小鼠模型:野生型C57BL/6小鼠是通过灌胃感染螺旋杆菌Helicobacter felis(H.felis)(ATCC49179)。H.felis感染后两周,隔周给小鼠喝含240ppm MNU的饮用水,总共12周(总共暴露6周),MNU开始处理后36周获得胃癌(中晚期)小鼠模型。
对TCGA数据库中胃腺癌核酸测序数据进行分析,如图1A所示,发现CD24的mRNA表达在胃癌样品中比正常胃组织中有明显的上调。
在螺旋杆菌Helicobacter felis(H.felis)和致癌剂MNU诱导的小鼠模型以及正常对照小鼠中,利用流式细胞法分析胃上皮细胞的CD24表达量,如图1B-C所示,发现发生胃癌的小鼠胃上皮比正常对照中CD24的蛋白表达明显上升。这些结果说明胃癌发生过程中,CD24的表达有显著的上调。
此外,如图2A所示,在TCGA数据库中分析发现胃癌组织中的CD24mRNA表达水平比另外两中免疫抑制分子CD47和PD-L1的表达更高。在H.felis和MNU诱导的小鼠胃癌模型中(MNU处理开始36周后),利用流式细胞分析同样发现E-Cadherin阳性的上皮细胞中CD24的表达比CD47和PD-L1的更高,这提示CD24在胃癌中可能是比CD47和PD-L1更理想的治疗靶点。
实施例2
胃癌小鼠治疗方案:为了进行抗体治疗,从开始用MNU饮用水处理小鼠后37周开始,每周两次腹腔注射50μg CD24单克隆抗体/只/针(R&D Systems),100μg PD-1单克隆抗体/只/针(Bio X Cell)或对照IgG。连续治疗6周。治疗结束后处死小鼠,并对胃组织进行检测。
如图3所示,在胃癌小鼠模型中,给已成瘤的小鼠腹腔注射CD24抗体、PD-1抗体或者IgG对照,经过6周的治疗后发现CD24抗体能明显减少胃部肿瘤面积,而PD-1抗体无显著作用。这提示,CD24抗体可以用于治疗中晚期胃癌,尤其是对PD-1不敏感和/或产生抗药性的胃癌。
免疫染色结果如图4所示,对胃组织切片进行HE染色,发现CD24抗体能明显减少胃部肿瘤的大小以及腺体结构的异常表型,而PD-1抗体无显著作用。
流式细胞法分析结果如图5所示,结果表明CD24抗体能明显增加CD4 T、CD8 T、B细胞和M1型巨噬细胞等具有抗肿瘤功能的免疫细胞的比例,并且能降低促肿瘤的调节T细胞以及M2型巨噬细胞的比例。
综上所述,CD24在胃癌小鼠的胃上皮细胞中表达显著高于对照样本,并且相较于PD-L1和CD47也显著高表达,该现象在人类肿瘤TCGA数据库中也得到了一致的结论。
通过对螺旋杆菌Helicobacter felis(H.felis)和致癌剂MNU诱导的胃癌小鼠模型进行CD24抗体治疗,发现有非常好的治疗效果。流式细胞术分析后,发现CD24发挥效果的机制是通过增加效应T细胞(尤其是CD4+和CD8+T细胞)的浸润以及减少调节T细胞的浸润来实现,另外,治疗的结果发现治疗亦促进了肿瘤相关巨噬细胞M2型向M1型转化,这提示通过CD24抗体治疗,小鼠体内激起了免疫效应来对抗免疫抑制的肿瘤微环境,抑制肿瘤进展,从而取得良好的治疗效果。
讨论
热稳定抗原CD24在组织和肿瘤干细胞中是重要的肿瘤干细胞标志物,并与肿瘤转移、侵袭密切相关。此外,还广泛用作分化造血细胞和神经元细胞的标志物。在许多不同肿瘤类型中,均发现了CD24的高水平表达,在一项新的研究中,研究人员也发现CD24是一种新的“不要吃我”的信号('don't eat me'signal),这提示CD24是癌症免疫疗法的潜在靶标。
虽然CD24通常在肿瘤细胞中广泛表达,但并不代表抑制CD24一定可以对癌症产生治疗效果,如白血病等癌症对CD24抑制剂不敏感,所以通过抑制CD24治疗癌症的方法仍需进一步研究。
而本发明首次通过实验证明了CD24抑制剂对胃癌(尤其是中晚期胃癌)的显著疗效,从而提供了一种新的胃癌治疗方法。
在本发明提及的所有文献都在本申请中引用作为参考,就如同每一篇文献被单独引用作为参考那样。此外应理解,在阅读了本发明的上述讲授内容之后,本领域技术人员可以对本发明作各种改动或修改,这些等价形式同样落于本申请所附权利要求书所限定的范围。
