چکیده

We have established several HLA-A2.1-transgenic rabbit lines to provide a host to study CD8(+) T cell responses during virus infections. HLA-A2.1 protein expression was detected on cell surfaces within various organ tissues. Continuous cultured cells from these transgenic rabbits were capable of presenting both endogenous and exogenous HLA-A2.1-restricted epitopes to an HLA-A2.1-restricted epitope-specific CTL clone. A DNA vaccine containing an HLA-A2.1-restricted human papillomavirus type 16 E7 epitope (amino acid residues 82-90) stimulated epitope-specific CTLs in both PBLs and spleen cells of transgenic rabbits. In addition, vaccinated transgenic rabbits were protected against infection with a mutant cottontail rabbit papillomavirus DNA containing an embedded human papillomavirus type 16 E7/82-90 epitope. Complete protection was achieved using a multivalent epitope DNA vaccine based on epitope selection from cottontail rabbit papillomavirus E1 using MHC class I epitope prediction software. HLA-A2.1-transgenic rabbits will be an important preclinical animal model system to study virus-host interactions and to assess specific targets for immunotherapy.

Using HLA-A2.1 Transgenic Rabbit Model to Screen and Characterize New HLA-A2.1 Restricted Epitope DNA Vaccines.

We have established an HLA-A2.1 transgenic rabbit /cottontail rabbit papillomavirus (CRPV) infection model. Using this novel transgenic animal model, we reported earlier that a multivalent epitope DNA vaccine (CRPVE1ep1-5) containing five HLA-A2.1 restricted epitopes from CRPVE1 (42-50, 149-157, 161-169, 245-253 and 303-311) was successful in providing strong and specific protective and therape...

Establishment of a cottontail rabbit papillomavirus/HLA-A2.1 transgenic rabbit model.

Three transgenic rabbit lines that express a well-characterized human major histocompatibility complex class I (MHC-I) gene (HLA-A2.1) have been established. All three lines carry the HLA-A2.1 heavy chain and are able to pass the transgene to their offspring with both the outbred and the inbred EIII/JC genetic background. HLA-A2.1 colocalizes exclusively with rabbit MHC-I on the cell surfaces. ...

Cytotoxic T lymphocytes from HLA-A2.1 transgenic mice define a potential human epitope from simian virus 40 large T antigen.

Recent reports have documented the presence of SV40 large T antigen (T ag) sequences in a number of human tumors and raised the question of whether cellular immunity to T ag is elicited in such individuals. We used HLA-A2.1 transgenic C57BL/6 mice to identify an epitope from T ag recognized by CD8+ CTLs when presented by this human MHC class I molecule. Immunization of HLA-A2.1 transgenic mice ...
