    摘要: This invention provides a new approach to the design of a virus with a defective replication cycle, which can be rescued by wild type virus co-infection, and which expresses foreign antigenic epitopes that contribute to the elimination of virus infected cells and then to viral clearance. The vector of the invention, by expression of epitopes derived from common pathogens, by-passes existing tolerance of virus specific T cell responses. The vector will only replicate in virus infected cells.

    摘要: Nucleotide vector composition containing such vector and vaccine for immunization against hepatitis. Nucleotide vector comprising at least one gene or one complementary DNA coding for at least a portion of a virus, and a promoter providing for the expression of such gene in muscle cells. The gene may be the S gene of the hepatitis B virus. A nucleotide vector composition when administered to even chronic HBV carriers is capable of breaking T cell tolerance to the surface antigens of hepatitis B virus. A vaccine preparation containing said bare DNA is injected into the host previously treated with a substance capable of inducing a coagulating necrosis of the muscle fibers.

    摘要: H-2 class I negative, HLA-A2.1 transgeniic HHD mice were used for a comparative evaluation of the immunogenicity of HLA-A2.1 restricted human tumor-associated CTL epitopes. A hierarchy was established among these epitopic peptides injected into mice in IFA which correlates globally with their capacity to bind and stabilize HLA-A2.1 molecules. Co-injection of a helper peptide enhanced most CTL responses. In contrast, classical HLA class I transgenic mice which still express their own class I molecules did not, in most cases, develop H.A.-A2.1-restricted CTL responses under the same experimental conditions. Different monoepitopic immunization strategies of acceptable clinical usage were compared in HHD mice. Recombinant Ty-virus-like particles, or DNA encoding epitopes fused to the hepatitis B virus middle envelope protein gave the best results. Using this latter approach and a melanoma-based polyepitope construct, CTL responses against five distinct epitopes could be elicited simultaneously in a single animal. Thus, HHD mice provide a versatile animal model for preclinical evaluation of peptide-based cancer immunotherapy.
