Inhibitory Effects of Cytomegalovirus Proteins US2 and US11 Point to Contributions from Direct Priming and Cross-Priming in Induction of Vaccinia Virus-Specific CD8+ T Cells

Abstract excerpt

The extent to which naive CD8(+) CTLs (T(CD8)(+)) are primed by APCs presenting endogenous Ags (direct priming) or Ags acquired from other infected cells (cross-priming) is a critical topic in basic and applied immunology. To examine the contribution of direct priming in the induction of VV-specific T(CD8)(+), we generated recombinant vaccinia viruses that express human CMV proteins (US2 and US11) that induce the...
