Cross-presentation is the ability of certain antigen-presenting cells to take up, process and present extracellular antigens with MHC class I molecules to CD8 T cells (cytotoxic T cells). Cross-priming, the result of this process, describes the stimulation of naive cytotoxic CD8⁺ T cells into activated cytotoxic CD8⁺ T cells. This process is necessary for immunity against most tumors and viruses that do not readily infect antigen-presenting cells, but rather intracellular tumors and viruses that infect peripheral tissue cells. Cross presentation is also required for the induction of cytotoxic immunity by vaccination with protein antigens, for example, tumour vaccination.
An adjuvant polypeptide, a nanocarrier and application of the nanocarrier in vaccine adjuvant
An adjuvant polypeptide, a nano-carrier and application of the nano-carrier in vaccine adjuvant, the present application relates to the field of vaccine.The present application solves the problems of poor antigen compatibility, lack of targeting, low delivery efficiency and insufficient preparation stability of traditional adjuvant.The amino acid sequence of the adjuvant polypeptide Adp is VLGKLAKVAI.The nano-carrier is prepared from the adjuvant polypeptide and antigen.The nano-carrier is prepared by mixing the adjuvant polypeptide and antigen through in-situ radical polymerization.The application of the nano-carrier in vaccine adjuvant.The present application screens a new vaccine adjuvant by bioinformatics method, so that it has the abilities of dendritic cell targeting and intracellular STING pathway activation, thereby enhancing the cross-presentation of antigen.Based on this, the new adjuvant is coupled with monomer, and an intelligent vaccine delivery system is constructed by in-situ polymerization method, so as to realize the efficient delivery of tumor cell membrane protein antigen and improve the immunotherapy effect of tumor vaccine.

FLT3l–flagellin hybrid adjuvant with enhanced antigen cross-presentation efficacy and vaccine composition comprising same
PCT designated stageWO2026106053A1Antibody medical ingredientsAntineoplastic agentsDendritic cellAdjuvant
The present invention relates to a FLT3L–flagellin hybrid adjuvant with enhanced antigen cross-presentation efficacy and a vaccine composition comprising same. The hybrid adjuvant of the present invention demonstrated significant therapeutic efficacy as an adjuvant for a therapeutic cancer vaccine in a preclinical mouse model of cervical cancer, resulting in complete tumor regression and sustained protection. In addition, the hybrid adjuvant of the present invention induced tumor-specific antigen CD8+ T cell responses and progenitor-exhausted CD8+ T cells (Tpex) due to an increase in cross-presentation by conventional type 1 dendritic cells (cDC1) in tumor-draining lymph nodes and the tumor microenvironment, and the combination of TCV having the hybrid adjuvant applied thereto and anti-PD-1 therapy significantly improves survival outcomes in anti-PD-1–resistant tumors, and thus can be advantageously applied in anticancer immunotherapy using therapeutic cancer vaccines.
