Abstract:
:Development of a HIV-1 vaccine is a major global priority. The yellow fever virus (YFV) attenuated vaccine 17D is among the most effective of currently used vaccines. However, the stability of the YFV17D vector when carrying non-flavivirus genes has been problematic. We have constructed and expressed HIV-1 Env in YFV17D with either single transmembrane (STM) or double transmembrane (DTM) YFV E protein domains for the development of anti-HIV antibodies. Here we describe modifications of the YFV17D vector such that HIV-1 Env gp120 is expressed in up to 5 passages in Vero cells. Immunization with recombinant YFV17D vector prime followed by HIV-1 CH505 TF gp120 protein boosts were able to induce neutralizing antibodies for a HIV-1 tier 1 isolate in mice. This modified YFV vector may be a starting point for constructing HIV-1 vaccine candidate priming vectors.
