Cancer vaccines must activate multiple immune cell types to be effective against aggressive tumors, but design considerations for these multi-targeted vaccines are underexplored. Herein, we demonstrate the impact of structural presentation of multiple antigenic peptides on immune responses at transcriptomic, cellular, and organismal levels. Spherical nucleic acid (SNA) nanoconstructs were used to investigate differences in antigen processing, cytokine production, and memory stemming from spatial distribution and nanoscale placement of two antigen classes to activate two T cell types. A single dual-antigen SNA (DA-SNA), compared to two single-antigen SNAs, elicited a 30% and two-fold increase in antigen-specific T cell activation and proliferation, respectively. Antigen placement within DA-SNAs changed immunological gene expression and tumor growth: encapsulating helper and externally-conjugating cytotoxic T cell antigens (termed DA-SNA 2) elevated antitumor gene pathways, stalling tumors in mice with lymphoma. When combined with anti-PD-1 checkpoint inhibitor in clinically relevant melanoma, DA-SNA 2 suppressed tumors and increased circulating T cell memory. This work highlights the importance of implementing structural control afforded by modular nanoscale architectures to synthesize multi-antigen vaccines with improved efficacy.
