The immediate-early gene ie14/vsag of herpesvirus saimiri has homology with murine superantigens. We compared the pathogenesis of infection with either ie14/vsag deletion mutants or wild-type virus C488 in cottontop tamarin monkeys (Saguinus oedipus). Two weeks after infection, all animals developed acute T-cell lymphomas independently of the presence of the viral ie14/vsag gene.
Recent crystallographic studies show that the T-cell receptor has a largely immunoglobulin-like structure and binds to MHC-peptide complexes through loops from paired Valpha and Vbeta domains that focus on the central amino acids of the MHC-bound peptide, and to bacterial superantigens via peripheral aspects of the Vbeta domain.
