Herpes Virus Icp47 And Us11 Suppression Of Ctl Activity Adapted For Use In Gene Therapy , Thomas Joseph Radosevich Jan 2003

Herpes Virus Icp47 And Us11 Suppression Of Ctl Activity Adapted For Use In Gene Therapy , Thomas Joseph Radosevich

Retrospective Theses and Dissertations

A major stumbling block encountered in gene therapy clinical trials has been the rapid destruction of the therapeutic product by the host's immune response. The goal of this work is to diminish the host Cytotoxic T Lymphocyte (CTL) response to gene therapy transgenes and transduced cells by incorporating immunosuppression genes into gene therapy vectors. The processing and presentation of antigens through the class I Major Histocompatibility Complex (class I MHC) pathway is known to be an early response to viral infection. Disruption of the class I MHC pathway results in a decrease of the CD8+ CTL response and prolongs ...


Evaluation Of Mycobacterial Esat-6 As A Type-I Immune Enhancing Adjuvant , Sreekumar Ambalakkat Menon Jan 1999

Evaluation Of Mycobacterial Esat-6 As A Type-I Immune Enhancing Adjuvant , Sreekumar Ambalakkat Menon

Retrospective Theses and Dissertations

The need for improved adjuvants has continued in spite of new vaccination strategies using recombinant proteins and genetic (DNA vectored) vaccines. The Mycobacterium tuberculosis protein ESAT-6 has been shown in mice to be involved in the recall of long-lived immunity and protection in mice against tuberculosis. Thus, this protein could potentially act as a molecular adjuvant enhancing antigen-specific Type I immune responses. This study examined the hypothesis that Es could enhance Type I responses against a second antigen in mice when presented as a fusion with that antigen. This was tested using ESAT-6 fusions with two Mycoplasma hyopneumoniae surface antigens ...


Characterization And Immunogenicity Of The Heat Shock Protein, Hsp60 Of Brucella Abortus , Dennis Gor Jan 1994

Characterization And Immunogenicity Of The Heat Shock Protein, Hsp60 Of Brucella Abortus , Dennis Gor

Retrospective Theses and Dissertations

Brucella abortus is the causative agent of bovine brucellosis, a disease that causes spontaneous abortion in cows. The most effective form of protection against this pathogen is immunization; however, Brucella abortus strain 19 (the standard vaccine against Brucella abortus) is not completely protective. The vaccination of laboratory mice with the heat shock protein, hsp60 derived from Brucella abortus, using live attenuated recombinant Salmonella typhimurium expressing this protein (hsp60) as a delivery system, and the characterization of the immune response to Brucella abortus hsp60 over a 12 week time course following vaccination is described;Infection of BALB/c strain of laboratory ...
