Abstract:DNA-based immunization induces a biased Th1 immune response, and offers a novel strategy for modulation of the Th2-associated response. Recent studies have provided evidence that antigen-induced allergic responses can be modulated in rodents immunized with plasmid DNAs encoding the sensitizing antigens. Further understanding of the regulatory mechanism involved and optimization of gene transfer/expression systems will assist greatly in proving the clinical utility of this process.
