Abstract:
:A DNA vaccine codifying the mycobacterial hsp65 can prevent infection with Mycobacterium tuberculosis in a prophylactic setting and also therapeutically reduce the number of bacteria in infected mice. The protective mechanism is thought to be related to Th1-mediated events that result in bacterial killing. To determine the best method of hsp65 introduction for vaccination efficacy against tuberculosis (TB), we evaluated the immunogenicity and protection of DNA-hsp65 administered by gene gun bombardment or intramuscular (i.m.) injection of naked DNA. Immunization by gene gun induced immune response with plasmid doses 100-fold lower than those required for intramuscular immunization. However, in contrast to intramuscular immunization, which was protective in these studies, gene gun immunization did not protect BALB/c mice against challenge infection.
