Robertson, Kevin A., Usherwood, Edward J., Nash, Anthony A.

Murine gammaherpesvirus 68-infected S11 cells were injected subcutaneously into nude mice. Adoptively transferred restimulated lymphocytes consistently elicited the regression of S11 tumors. CD4 T...

Latent Antigen Vaccination in a Model Gammaherpesvirus Infection

Usherwood, Edward J., Ward, Kimberley A., Blackman, Marcia A., Stewart, James P., Woodland, David L.

Vaccines that can reduce the load of latent gammaherpesvirus infections are eagerly sought. One attractive strategy is vaccination against latency-associated proteins, which may increase the...

Murid Herpesvirus 4 Strain 68 M2 Protein Is a B-Cell-Associated Antigen Important for Latency but Not Lymphocytosis

Macrae, Alastair I., Usherwood, Edward J., Husain, S. Mazher, Flaño, Emilio, Kim, In-Jeong, Woodland, David L., ...

This work describes analyses of the function of the murid herpesvirus 4 strain 68 (MHV-68) M2 gene. A frameshift mutation was made in the M2 open reading frame that caused premature termination of...

T-Cell Responses to the M3 Immune Evasion Protein of Murid Gammaherpesvirus 68 Are Partially Protective and Induced with Lytic Antigen Kinetics

Obar, Joshua J., Donovan, Douglas C., Crist, Sarah G., Silvia, Ondine, Stewart, James P., Usherwood, Edward J.

DNA vaccination with the M3 gene, encoding an immune evasion molecule expressed during both the acute lytic and persistent phases of murid gammaherpesvirus 68 infection, yielded a significantly lower...

Gammaherpesvirus Persistence Alters Key CD8 T-Cell Memory Characteristics and Enhances Antiviral Protection

Obar, Joshua J., Fuse, Shinichiro, Leung, Erica K., Bellfy, Sarah C., Usherwood, Edward J.

In herpesvirus infections, the virus persists for life but is contained through T-cell-mediated immune surveillance. How this immune surveillance operates is poorly understood. Recent studies of...
