Pilot Project, Year 3<\/h1>\n

Multivalent Display of HPV Antigens using Self-Assembling Peptides<\/h2>\n

Since the introduction of the first HPV vaccine in 2006, the prevalence of certain HPV types declined among women from the general population aged 14-24 years. The currently available HPV vaccine (Gardasil\u00ae 9) was developed using virus-like particles (VLPs). It prevents against nine of the over 150 HPV types; two that cause warts (types 6, 11) and seven that can cause cancer (types 16, 18, 31, 33, 45, 52, and 58). While effective, the HPV vaccine has certain limitations.<\/p>\n

For example, they require extensive purification protocols, two doses, and refrigeration. Therefore, research efforts continue to strive toward finding next-generation vaccines that have strong immunogenicity and are cost-effective.<\/p>\n

Recently, short synthetic self-assembled peptides showed promise as a vaccine platform. These peptides, similar to VLPs, spontaneously assemble into stable ordered amyloid-like fibrils. Unlike VLPs, the fibrils are extremely robust at varying temperatures, pH, and solvents. The self-assembled fibrils are also significantly larger than the small spherical VLPs. Thus, the fibrils allow for potential increased immunogenicity and cost-effectiveness.<\/p>\n

We hypothesized that self-assembled fibrils displaying HPV antigens produce strong immune responses due to the geometrical and multivalent display of peptide antigens along the fibril.<\/p>\n

To test this hypothesis, we synthesized previously identified HPV antigens that will be chemically conjugated to the self-assembling peptides fibrils. Immune responses were assessed using a common murine model. Potential vaccine candidates will be further assessed via an HPV challenge model in mice.<\/p>\n
