Enhancing the Immunogenicity and Efficacy of Vectored Vaccines
Dr. Hill and his colleagues are exploring a novel approach to enhancing the ability of plasmid DNA, pox, or adenoviral vectored vaccines to stimulate strong immune responses. Building on recent advances in understanding of pattern recognition molecules as well as intracellular signaling pathways, investigators are working to add intracellular adjuvants (molecular signals that have the potential to enhance immunogenicity) to the vaccine vectors. Also being explored is the effect of adding molecules designed to inhibit regulatory pathways that may be limiting protective immune response. The team is focusing on improving vectors for vaccines against malaria, HIV, and tuberculosis.
