癌症疫苗是一种很有前途的辅助免疫疗法,它可以刺激免疫系统识别肿瘤相关抗原,消除残留或复发的疾病。高免疫原性癌睾丸抗原NY-ESO-1在几种恶性肿瘤(包括三阴性乳腺癌、黑色素瘤、骨髓瘤和卵巢癌)中的异常和限制性表达,使NY-ESO-1成为癌症疫苗的一个有吸引力的抗原靶点。本研究描述了一种基于生物启发纳米材料平台技术的NY-ESO-1疫苗,特别是一种植物病毒纳米颗粒。30 nm二十面体植物病毒豇豆花叶病毒(CPMV)显示了人HLA-A2限制性肽抗原NY-ESO-1157-165的多个拷贝,在转基因人HLA-A2表达小鼠中表现出增强的抗原呈递细胞的摄取和激活,并刺激了强有力的CD8+ T细胞反应。免疫小鼠的CD8+ T细胞表现出抗原特异性增殖和癌细胞细胞毒性,突出了CPMV-NY-ESO-1疫苗对NY-ESO-1+恶性肿瘤的潜在应用。
Cancer vaccines are promising adjuvant immunotherapies that can stimulate the immune system to recognize tumor-associated antigens and eliminate the residual or recurring disease. The aberrant and restricted expression of highly immunogenic cancer testis antigen NY-ESO-1 in several malignancies, including triple-negative breast cancer, melanoma, myelomas, and ovarian cancer, makes NY-ESO-1 an attractive antigenic target for cancer vaccines. This study describes a NY-ESO-1 vaccine based on a bio-inspired nanomaterial platform technology, specifically a plant virus nanoparticle. The 30 nm icosahedral plant virus cowpea mosaic virus (CPMV) displaying multiple copies of human HLA-A2 restricted peptide antigen NY-ESO-1157–165 exhibited enhanced uptake and activation of antigen-presenting cells and stimulated a potent CD8+ T cell response in transgenic human HLA-A2 expressing mice. CD8+ T cells from immunized mice exhibited antigen-specific proliferation and cancer cell cytotoxicity, highlighting the potential application of a CPMV-NY-ESO-1 vaccine against NY-ESO-1+ malignancies.
