摘要

Unimicellar hyperstar macromolecular chimeras displaying multiple melanoma peptide antigens were prepared primarily via a combination of click chemistry and esterification reactions starting from a biodegradable hyperbranched polymer template. Solubilization of the hyperstars in aqueous solution afforded a multi-antigen unimicellar cancer nanovaccine of about 20 nm. The nanovaccine showed good biocompatibility and uptake by dendritic cells in vitro. An in vivo evaluation of the nanovaccine therapeutic efficacy against melanoma in mice implanted with B16OVA tumors revealed significantly greater T-cell recruitment and improved survival rates for mice treated with nanovaccine and adjuvant compared to non-treated mice.
