Hierarchy among multiple H-2b-restricted cytotoxic T-lymphocyte epitopes within simian virus 40 T antigen.
Simian virus 40 large tumor (T) antigen contains three H-2Db-restricted (I, II/III, and V) and one H-2Kb-restricted (IV) cytotoxic T lymphocyte (CTL) epitopes. We demonstrate that a hierarchy exists among these CTL epitopes, since vigorous CTL responses against epitopes I, II/III, and IV are detected following immunization of H-2b mice with syngeneic, T-antigen-expressing cells. By contrast, a ...
متن کاملCytotoxic T Lymphocyte Epitopes of HIV-1 Nef
Although a pivotal role of proteasomes in the proteolytic generation of epitopes for major histocompatibility complex (MHC) class I presentation is undisputed, their precise function is currently the subject of an active debate: do proteasomes generate many epitopes in definitive form, or do they merely generate the COOH termini, whereas the definitive NH(2) termini are cleaved by aminopeptidas...
متن کاملDevelopment of a dendritic cell vaccine encoding multiple cytotoxic T lymphocyte epitopes targeting hepatitis C virus.
The aim of the present study was to develop a dendritic cell (DC) vaccine encoding hepatitis C virus (HCV) multiple cytotoxic T lymphocyte (CTL) epitopes that can stimulate T cell responses in vitro, and can be used for immunization in vivo. DCs were infected with recombinant replication-defective adenoviruses (Ads) expressing 2 HCV sequences fused with green fluorescent protein (GFP) and FLAG ...
متن کاملHLA-A*0201-restricted CD8+ cytotoxic T lymphocyte epitopes identified from herpes simplex virus glycoprotein D.
Evidence obtained from both animal models and humans suggests that T cells specific for HSV-1 and HSV-2 glycoprotein D (gD) contribute to protective immunity against herpes infection. However, knowledge of gD-specific human T cell responses is limited to CD4+ T cell epitopes, with no CD8+ T cell epitopes identified to date. In this study, we screened the HSV-1 gD amino acid sequence for HLA-A*0...
متن کاملKinetics of Primary and Memory Cytotoxic T Lymphocyte Responses to Herpes Simplex Virus 1 Infection: Granzyme B Mediated CTL Activity
Background: Herpes simplex virus type 1 is one of the most common viruses among human population. Studies demonstrate the essential role of cell mediated immunity, especially CD8+ T cells, in prevention and clearance of HSV1. Objective: It is of great importance to improve our knowledge about the kinetics of CTL responses to primary and secondary HSV-1 infection. Methods: Using a sensitive tech...
