Given the continued spread of human immunodeficiency virus (HIV)-1 worldwide, developing efficient vaccine strategies against HIV-1 is a key task. We tested the safety and immunogenicity of a multicomponent, cell-based vaccine that consisted of antigen-expressing apoptotic bodies with or without autologous dendritic cells (DCs). The vaccine strategy involved transfection of human 293T cells with codon-optimized DNA vectors expressing env of HIV1084i, a newly transmitted pediatric HIV-1 clade C strain; SHIV89.6P tat; and SIVmac239 gag-protease. Apoptotic bodies were generated by heat shock and ultraviolet irradiation and mixed either with mouse DCs (DC-cell vaccine) or given directly (cell-only vaccine) to BALB/c mice for initial priming; boosts consisted of apoptotic bodies only. The immunogens were well tolerated with or without DCs. Compared with the cell-only vaccine, the DC-cell vaccine induced higher antibody titers against all three antigens, whereas virus-specific cytotoxic T lymphocyte responses were equally strong in both groups. Iso-type analysis of viral antigen-specific antibodies revealed a skewing toward helper T type 2 responses induced by the DC-cell vaccine but not by the cell-only vaccine. In summary, both vaccine strategies were safe and induced cellular as well as humoral antiviral immunity; the DC-based approach had the advantage of significantly stronger antibody responses.
