尽管它们具有潜力,但通过冻融或辐照制备的常规全细胞癌症疫苗在临床试验中显示出有限的治疗效果。最近的研究表明,用某些化疗药物如米托蒽醌治疗的癌细胞可以经历免疫原性细胞死亡(ICD)并启动抗肿瘤免疫应答。然而,目前还不清楚如何利用ICD进行癌症免疫治疗。在这里,我们提出了一种新的基于材料的策略,用于将免疫原性死亡的肿瘤细胞转化为癌症疫苗接种的强大平台,并在黑色素瘤和结肠癌的小鼠模型中展示其治疗潜力。我们已经产生了免疫原性死亡的肿瘤细胞表面修饰的载药纳米粒子。负载有佐剂纳米库的垂死肿瘤细胞在体外有效地促进树突状细胞的活化和抗原交叉呈递,并在体内引发稳健的抗原特异性CD8α+ T细胞。此外,全肿瘤细胞疫苗接种结合免疫检查点阻断导致约78%的CT26荷瘤小鼠的肿瘤完全消退,并建立了针对肿瘤复发的长期免疫力。我们在这里提出的策略可能会为针对个体患者肿瘤细胞的“个性化”癌症免疫治疗打开新的大门。
Despite their potential, conventional whole-cell cancer vaccines prepared by freeze-thawing or irradiation have shown limited therapeutic efficacy in clinical trials. Recent studies have indicated that cancer cells treated with certain chemotherapeutics, such as mitoxantrone, can undergo immunogenic cell death (ICD) and initiate antitumor immune responses. However, it remains unclear how to exploit ICD for cancer immunotherapy. Here, we present a new material-based strategy for converting immunogenically dying tumor cells into a powerful platform for cancer vaccination and demonstrate their therapeutic potential in murine models of melanoma and colon carcinoma. We have generated immunogenically dying tumor cells surface-modified with adjuvant-loaded nanoparticles. Dying tumor cells laden with adjuvant nanodepots efficiently promote activation and antigen cross-presentation by dendritic cells in vitro and elicit robust antigen-specific CD8α+ T-cells in vivo. Furthermore, whole tumor-cell vaccination combined with immune checkpoint blockade leads to complete tumor regression in ~78% of CT26 tumor-bearing mice and establishes long-term immunity against tumor recurrence. Our strategy presented here may open new doors to “personalized” cancer immunotherapy tailored to individual patient’s tumor cells.
