Genetic immunotherapy of infectious diseases and cancer by targeting DNA encoded antigen chimeras to MHC II; HIV-1 peptide vaccine; bioinformatic analysis of viral and other protein structures

The research of this laboratory is directed at programs for peptide and genetic immunotherapy and bioinformatic analysis of the immune structure of virus and cancer proteins.

  • A novel strategy for genetic immunotherapy by antigen targeting to helper T cells - We have developed a strategy for targeting the protein products of DNA vaccines to the major histocompatability complex (MHC) class II pathway for antigen presentation to CD4+ helper T cells.  The DNA vaccine is constructed as a recombinant gene chimera, containing the antigen sequence attached to the the LAMP lysosomal membrane protein that is co-localized with MHC II of antigen presenting cells. This technology is now widely studied for many vaccine applications.  Studies in this laboratory are mainly directed at HIV-1 and flavivirus vaccines.
