Abstract:
With the goal of creating antigen-directed immunotherapeutics that can be safely administered directly to patients, Immune Design has developed a platform of novel integration-deficient lentiviral vectors that target and deliver antigen-encoding nucleic acids to dendritic cells (DCs) in order to promote the activation of antigen-specific effector CD8 T cells. This platform, termed DCVex(TM), utilizes a novel genetic variant of a Sindbis virus envelope glycoprotein with post-translational carbohydrate modifications in combination with Vpx, a SIVmac viral accessory protein, to achieve efficient targeting and transduction of DCs. In addition, DCVex(TM) incorporates safety features in its design that include redundant mechanisms to render DCVex(TM) integration-deficient, as well as genetic modifications that eliminate psi-gag recombination between split genome components. The characteristics that allow DCVex(TM) to specifically transduce human DCs and the advances that DCVex(TM) brings to conventional third-generation lentiviral vector design demonstrate its potential as a vaccine designed to utilize DCs for cancer immunotherapy.
