13. Comparison of BCG and different delivery systems of DNAhsp65 vaccine for the induction of protection against tuberculosis in guinea pigs / Comparação de diferentes sistemas de liberação da vacina DNA-hsp65 na indução de proteção contra tuberculose em cobaias
As grandes mudanças para os pesquisadores da área de vacinas sao a optimizaçao das vacinas de DNA para uso em humanos ou animais de grande porte e criar vacinas efetivas de uma única dose usando sistemas de liberação controlada apropriados. O plasmídeo de DNA codificando a proteína de heatshock 65 (hsp65) (DNA-hsp65) foi capaz de induzir resposta imu

14. The human immunodeficiency virus preventive vaccine research at the French National Agency for acquired immunodeficiency syndrome research
The human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic is of unprecedented gravity and is spreading rapidly, notably in the most disadvantaged regions of the world. The search for a preventive vaccine is thus an absolute priority. For over 10 years the French National Agency for AIDS research (ANRS) has been committed to an o

15. Importance of CD8 T cell-mediated immune response during intracellular parasitic infections and its implications for the development of effective vaccines
Parasitas intracelulares obrigatórios como Plasmodium sp, Trypanosoma cruzi, Toxoplasma gondii e Leishmania sp são responsáveis pela infecção de milhões de indivíduos a cada ano. Estes parasitas são capazes de liberar antígenos no citoplasma de células infectadas do hospedeiro que são apresentados por moléculas de MHC classe I para células T CD8

16. Protective CD8+ T cell responses against the pre-erythrocytic stages of malaria parasites: an overview
CD8+ T cells have been implicated as critical effector cells in protection against the pre-erythrocytic stage of malaria in mice and humans following irradiated sporozoite immunization. Immunization experiments in animal models by several investigators have suggested different strategies for vaccination against malaria and many of the targets from liver stag

17. DNA Immunization with Hepatitis C Virus (HCV) Polycistronic Genes or Immunization by HCV DNA Priming-Recombinant Canarypox Virus Boosting Induces Immune Responses and Protection from Recombinant HCV-Vaccinia Virus Infection in HLA-A2.1-Transgenic Mice
We studied immune responses to hepatitis C virus (HCV) genes delivered as DNA encoding the entire HCV protein coding genome in two polycistronic plasmids encoding HCV capsid-E1-E2-NS2-NS3 and HCV NS3-NS4-NS5 in HLA-A2.1-transgenic mice. Immune responses to HCV DNA prime and recombinant canarypox virus boost were also studied with the above constructs. At 8 w

18. A DNA Prime-Mycobacterium bovis BCG Boost Vaccination Strategy for Cattle Induces Protection against Bovine Tuberculosis†
The variable efficacy of bacillus Calmette-Guérin (Mycobacterium bovis BCG) in protecting humans and cattle against tuberculosis has prompted a search for a more effective vaccination regimen. A prime-boost strategy was investigated in cattle naturally sensitized to environmental mycobacteria by using a combination of three DNA vaccines coding for Hsp 65, H

19. Gender Differences in Human Immunodeficiency Virus Type 1-Specific CD8 Responses in the Reproductive Tract and Colon following Nasal Peptide Priming and Modified Vaccinia Virus Ankara Boosting
Induction of mucosal anti-human immunodeficiency virus type 1 (HIV-1) T-cell responses in males and females will be important for the development of a successful HIV-1 vaccine. An HIV-1 envelope peptide, DNA plasmid, and recombinant modified vaccinia virus Ankara (rMVA) expressing the H-2Dd-restricted cytotoxic T lymphocyte P18 epitope were used as immunogen

20. Plasmid Chemokines and Colony-Stimulating Factors Enhance the Immunogenicity of DNA Priming-Viral Vector Boosting Human Immunodeficiency Virus Type 1 Vaccines
Heterologous “prime-boost” regimens that involve priming with plasmid DNA vaccines and boosting with recombinant viral vectors have been shown to elicit potent virus-specific cytotoxic T-lymphocyte responses. Increasing evidence, however, suggests that the utility of recombinant viral vectors in human populations will be significantly limited by preexist

21. Application of Mycobacterial Proteomics to Vaccine Design: Improved Protection by Mycobacterium bovis BCG Prime-Rv3407 DNA Boost Vaccination against Tuberculosis
Information from comparative proteome analysis of Mycobacterium tuberculosis and Mycobacterium bovis bacillus Calmette-Guérin (BCG) principally allows prediction of potential vaccine candidates. Thirty-six M. tuberculosis DNA vaccine candidates identified by comparative proteome analysis were evaluated in the mouse model for protection against low-dose aero

22. Rapid Appearance of Secondary Immune Responses and Protection from Acute CD4 Depletion after a Highly Pathogenic Immunodeficiency Virus Challenge in Macaques Vaccinated with a DNA Prime/Sendai Virus Vector Boost Regimen
Heterologous prime/boost regimens are AIDS vaccine candidates because of their potential for inducing cellular immune responses. Here, we have developed a prime/boost regimen leading to rapid control of highly pathogenic immunodeficiency virus infection in macaques. The strategy, priming by an env and nef deletion-containing simian-human immunodeficiency vir

23. Enhanced Immunogenicity of CD4+ T-Cell Responses and Protective Efficacy of a DNA-Modified Vaccinia Virus Ankara Prime-Boost Vaccination Regimen for Murine Tuberculosis
DNA vaccines whose DNA encodes a variety of antigens from Mycobacterium tuberculosis have been evaluated for immunogenicity and protective efficacy. CD8+ T-cell responses and protection achieved in other infectious disease models have been optimized by using a DNA immunization to prime the immune system and a recombinant virus encoding the same antigen(s) to

24. Effective Induction of Simian Immunodeficiency Virus-Specific Cytotoxic T Lymphocytes in Macaques by Using a Multiepitope Gene and DNA Prime-Modified Vaccinia Virus Ankara Boost Vaccination Regimen
DNA and modified vaccinia virus Ankara (MVA) are vaccine vehicles suitable and safe for use in humans. Here, by using a multicytotoxic T-lymphocyte (CTL) epitope gene and a DNA prime-MVA boost vaccination regimen, high levels of CTLs specific for a single simian immunodeficiency virus (SIV) gag-derived epitope were elicited in rhesus macaques. These vaccine-
