CpG ODN are toll-like receptor 9 (TLR9) agonists that can enhance antigen presentation by antigen presenting cells (APCs) such as dendritic cells (DCs). The most potent antigen-specific responses are seen when CpG ODN and the antigen are co-localized in the same APC. CpG ODN-antigen fusion molecules and biodegradable microparticles entrapping CpG ODN and antigen can ensure both components are delivered to the same APC. In this study, we compared the efficacy of the CpG-ODN fusion molecules against biodegradable microparticles entrapping antigen and CpG ODN. Microparticles were prepared using a double emulsion solvent evaporation methodology. CpG ODN-OVA fusion molecules were prepared by mixing maleimide-activated protein with thiolated CpG ODN. Both CpG ODN-OVA fusion molecules and microparticles co-entrapping CpG ODN and OVA generated stronger IgG2a and interferon-gamma (IFN-gamma) responses than delivery of soluble CpG ODN and OVA. The microparticles generated stronger IgG2a and IFN-gamma immune responses than did CpG ODN-antigen fusion molecules.
