Vaccination with trifunctional nanoparticles that address CD8+ dendritic cells inhibits growth of established melanoma

AIM: We wanted to assess the potency of a trifunctional nanoparticle (NP) that targeted and activated CD8+ dendritic cells (DC) and delivered an antigen to induce antitumor responses.

MATERIALS & METHODS: The DC targeting and activating properties of ferrous NPs conjugated with immunostimulatory CpG-oligonucleotides, anti-DEC205 antibody and ovalbumin (OVA) as a model antigen to induce antigen-specific T-cell responses and antitumor responses were analyzed.

RESULTS: OVA-loaded NP conjugated with immunostimulatory CpG-oligonucleotides and anti-DEC205 antibody efficiently targeted and activated CD8+ DC in vivo, and induced strong OVA-specific T-cell activation. Vaccination of B16/OVA tumor-burdened mice with this NP formulation resulted in tumor growth arrest.

CONCLUSION: CD8+ DC-targeting trifunctional nanocarriers bear significant potential for antitumor immunotherapy.
