  • Publication number: 20020072504
    Abstract: DNA vaccines which incorporate genetic sequences encoding sorting signals which direct an expressed antigen to a specific cellular organelle facilitate loading of the antigen onto a Class I or Class II MHC molecule for immune presentation. These vaccines are a nucleic acid construct of a genetic sequence encoding a protein or peptide antigen and a sorting signal which will direct expressed antigen to the ER or endosomal-lysosomal compartments within the cell. The resulting constructs can be used as naked DNA vaccines, packaged in liposomes, or coated onto colloidal gold particles. The construct might also be delivered in an expression vector which is expressed in cells of the organism being immunized.
