The development of prophylactic cancer vaccines typically involves the selection of combinations of tumour-associated antigens, tumour-specific antigens and neoantigens. Here we show that membranes from induced pluripotent stem cells can serve as a tumour-antigen pool, and that a nanoparticle vaccine consisting of self-assembled commercial adjuvants wrapped by such membranes robustly stimulated innate immunity, evaded antigen-specific tolerance and activated B-cell and T-cell responses, which were mediated by epitopes from the abundant number of antigens shared between the membranes of tumour cells and pluripotent stem cells. In mice, the vaccine elicited systemic antitumour memory T-cell and B-cell responses as well as tumour-specific immune responses after a tumour challenge, and inhibited the progression of melanoma, colon cancer, breast cancer and post-operative lung metastases. Harnessing antigens shared by pluripotent stem cell membranes and tumour membranes may facilitate the development of universal cancer vaccines.
预防性癌症疫苗的研发通常涉及肿瘤相关抗原、肿瘤特异性抗原和新抗原组合的选择。我们在此表明,诱导多能干细胞的膜可作为肿瘤抗原库,并且一种由此类膜包裹的自组装商业佐剂组成的纳米颗粒疫苗能有力地刺激先天免疫,规避抗原特异性耐受并激活B细胞和T细胞反应,这些反应由肿瘤细胞和多能干细胞膜之间共享的大量抗原中的表位介导。在小鼠中,该疫苗在肿瘤攻击后引发全身性抗肿瘤记忆T细胞和B细胞反应以及肿瘤特异性免疫反应,并抑制黑色素瘤、结肠癌、乳腺癌和术后肺转移的进展。利用多能干细胞膜和肿瘤膜共享的抗原可能有助于通用癌症疫苗的研发。
