Immunodominant H-2D Correlates with CTL Recognition of an Resistance to Polyoma Virus-Induced Tumors

Visualization of polyoma virus-specific CD8+ T cells in vivo during infection and tumor rejection.

T cells are critical for clearing infection and preventing tumors induced by polyoma virus, a natural murine papovavirus. We previously identified the immunodominant epitope for polyoma virus-specific CTL in tumor-resistant H-2k mice as the Dk-restricted peptide, MT389-397, derived from the polyoma middle T oncoprotein. In this study, we developed tetrameric Dk complexes containing the MT389-39...

Virus-Specific CTL Epitopes by Immunodominant Polyoma Cross-Recognition of Two Middle T Protein

Frequency of BK Polyoma Virus in Bladder Cancer

The BK virus a member of the Polyomaviruses family was first isolated from the urine of the kidney recipient. Infection with this virus and infection usually occurs in childhood (5-9 years) but most of the time (90%) of sera are positive and without symptoms. Polyomaviruses including the BK virus have also been suggested to be a contributing factor to some cancers in humans such as brain tumors...

Capsid-specific cytotoxic T lymphocytes recognize three distinct H-2D(b)-restricted regions of the BeAn strain of Theiler's virus and exhibit different cytokine profiles.

The role of virus-specific cytotoxic T lymphocytes (CTL) in Theiler's murine encephalomyelitis virus (TMEV)-induced demyelinating disease, a viral model for multiple sclerosis, is not yet clear. To investigate the specificity and function of CTL generated in response to TMEV infection, we generated a panel of overlapping 20-mer peptides encompassing the entire capsid and leader protein region o...

Cytotoxic T-lymphocyte epitope immunodominance in the control of choroid plexus tumors in simian virus 40 large T antigen transgenic mice.

The simian virus 40 (SV40) large tumor antigen (Tag) is a virus-encoded oncoprotein which is the target of a strong cytotoxic T-lymphocyte (CTL) response. Three immunodominant H-2(b)-restricted epitopes, designated epitopes I, II/III, and IV, have been defined. We investigated whether induction of CTLs directed against these Tag epitopes might control Tag-induced tumors in SV11(+) (H-2(b)) mice...
