摘　　要：The conventional immunoadjuvants in vaccine have weak effect on stimulating antigen presentation and activating anti-tumor immunity.Unexpectedly,we discovered that non-pathogenic Sendai virus(SeV)could activate antigen-presenting cells(APCs)represented by dendritic cells(DCs).Here,we designed an injectable SeV-based hydrogel vaccine(SHV)to execute multi-channel recruitment and stimulation of DCs for boosting the specific immune response against tumors.After the release of the NIR-triggered antigens from tumor cells,dendritic cells around the vaccine efficiently transport the antigens to lymph nodes and present them to T lymphocytes,thereby inducing systemic anti-tumor immune memory.Our findings demonstrated that the SHV with excellent universality,convenience and flexibility has achieved better immune protection effects in inhibiting the occurrence of melanoma and breast cancer.In conclusion,the SHV system might serve as the next generation of personalized anti-tumor vaccines with enhanced features over standard vaccination regimens,and represented an alternative way to suppress tumorigenesis.
