Delivery of DNA vaccine with in vivo electroporation enhances cellular immune responses. A DNA vaccine encoding HIV-1 consensus immunogens was injected intramuscularly with or without EP into rhesus macaques. Interferon (IFN) gamma ELISpots were performed 2 weeks after the third (final) immunization; total antigen-specific cellular responses are shown, n = 5 per group. ELISpot, enzyme-linked immunospot assay; HIV-1, human immunodeficiency virus-1; SFU, spot-forming units; PBMCs, peripheral blood mononuclear cells; IM, intramuscular injection; IL, interleukin.
