Epstein-Barr virus: adaptation to a life within the immune system.

Epstein-Barr virus has developed multiple strategies to ensure its long-term persistence in the infected B cells of immunocompetent hosts. These include the establishment of cell-phenotype-specific programs of viral gene expression and the transduction of cellular genes that modulate immune responses. Cytotoxic T cells may specifically influence the evolution of this genetically stable virus.
