DNA vaccine delivery by attenuated intracellular bacteria.
Vaccination by intramuscular or intradermal injection of antigen-encoding DNA is a promising new approach leading to strong cellular and humoral immune responses. Since bone-marrow derived antigen presenting cells (APC) seem to induce these immune responses after migration to the spleen, it is desirable to deliver DNA vaccines directly to splenic APC. Recently, attenuated intracellular bacteria have been exploited for the introduction of DNA vaccine vectors into different cell types in vitro as well as in vivo and offer an attractive alternative to the direct inoculation of naked plasmid DNA.
