许多抗肿瘤疫苗最近显示出有望上调针对肿瘤抗原的免疫反应并提高患者的生存率。在这项研究中,我们检查了使用表达 IL-15 的肿瘤细胞进行疫苗接种的有效性,并检查了它们上调对肿瘤抗原的免疫反应的能力。我们证明IL-15与其受体IL-15Rα的共表达增加了细胞表面IL-15的表达和分泌。我们表明,使用重组腺病毒在小鼠 TRAMP-C2 前列腺或 TS/A 乳腺肿瘤中表达 IL-15 和 IL-15Rα 的基因转移方法可诱导抗肿瘤免疫反应。由此我们开发了一个疫苗平台,由共表达 IL-15 和 IL-15Rα 的 TRAMP-C2 前列腺癌细胞或 TS/A 乳腺癌细胞组成,当小鼠受到肿瘤攻击时,可以抑制肿瘤形成。与接受单独表达IL-15的细胞或未修饰的肿瘤细胞的动物相比,肿瘤生长的抑制导致存活率提高。接种共表达 IL-15 和 IL-15Rα 的肿瘤细胞的动物表现出 CD8+ T 和 NK 细胞的肿瘤浸润程度更高,以及抗肿瘤 CD8+ T 细胞反应增强。使用 IL-15/IL-15Rα 修饰的 TS/A 乳腺癌细胞进行疫苗接种,为接受无关小鼠 TUBO 乳腺癌细胞攻击的小鼠提供了生存优势,表明同种异体 IL-15/IL-15Rα 表达疫苗的潜力。
A number of antitumor vaccines have shown recent promise up-regulating immune responses against tumor antigens and improving patient survival. In this study we examine the effectiveness of vaccination using IL-15 expressing tumor cells and examined their ability to up-regulate immune responses to tumor antigens. We demonstrated that the co-expression of IL-15 with its receptor, IL-15Rα, increased the cell-surface expression and secretion of IL-15. We show that a gene transfer approach using recombinant adenovirus to express IL-15 and IL-15Rα in murine TRAMP-C2 prostate or TS/A breast tumors induced antitumor immune responses. From this we developed a vaccine platform, consisting of TRAMP-C2 prostate cancer cells or TS/A breast cancer cells co-expressing IL-15 and IL-15Rα that inhibited tumor formation when mice were challenged with tumor. Inhibition of tumor growth led to improved survival when compared to animals receiving cells expressing IL-15 alone or unmodified tumor cells. Animals vaccinated with tumor cells co-expressing IL-15 and IL-15Rα showed greater tumor infiltration with CD8+ T and NK cells, as well as increased antitumor CD8+ T-cell responses. Vaccination with IL-15/IL-15Rα-modified TS/A breast cancer cells provided a survival advantage to mice challenged with unrelated murine TUBO breast cancer cells indicating the potential for allogeneic IL-15/IL-15Rα expressing vaccines.
