基于新抗原的个性化癌症疫苗的开发已成为癌症免疫治疗的新方向。两种形式的癌症疫苗已得到广泛研究:肿瘤相关抗原(包括蛋白质、肽或肿瘤裂解物)脉冲树突状细胞 (DC) 疫苗和蛋白质或肽佐剂疫苗。然而,当使用相同的抗原时,不同的免疫方式可能会产生不同的治疗效果和免疫反应。因此,有必要选择更有效的新抗原疫苗接种方法。在这项研究中,我们比较了新抗原脉冲 DC 疫苗和使用鼠肺癌 (LL2) 候选新抗原的新抗原佐剂疫苗之间的免疫和抗肿瘤效果的差异。酶联免疫斑点 (ELISPOT) 测定显示,4/6 的新抗原佐剂疫苗和 6/6 的新抗原脉冲 DC 疫苗诱导了强烈的 T 细胞免疫反应。此外,2/6 的新抗原佐剂疫苗和 5/6 的新抗原脉冲 DC 疫苗表现出有效的抗肿瘤作用。结果表明,新抗原脉冲DC疫苗在激活免疫反应和抑制肿瘤生长方面均优于新抗原佐剂疫苗。我们的资金为选择在个体化肿瘤免疫疗法中使用新抗原的免疫方式提供了实验基础。
Development of personalized cancer vaccines based on neoantigens has become a new direction in cancer immunotherapy. Two forms of cancer vaccines have been widely studied: tumor-associated antigen (including proteins, peptides, or tumor lysates)-pulsed dendritic cell (DC) vaccines and protein- or peptide-adjuvant vaccines. However, different immune modalities may produce different therapeutic effects and immune responses when the same antigen is used. Therefore, it is necessary to choose a more effective neoantigen vaccination method. In this study, we compared the differences in immune and anti-tumor effects between neoantigen-pulsed DC vaccines and neoantigen-adjuvant vaccines using murine lung carcinoma (LL2) candidate neoantigens. The enzyme-linked immunospot (ELISPOT) assay showed that 4/6 of the neoantigen-adjuvant vaccines and 6/6 of the neoantigen-pulsed DC vaccines induced strong T-cell immune responses. Also, 2/6 of the neoantigen-adjuvant vaccines and 5/6 of the neoantigen-pulsed DC vaccines exhibited potent anti-tumor effects. The results indicated that the neoantigen-pulsed DC vaccines were superior to the neoantigen-adjuvant vaccines in both activating immune responses and inhibiting tumor growth. Our fundings provide an experimental basis for the selection of immune modalities for the use of neoantigens in individualized tumor immunotherapies.
