Indeed, in vitro virus-activated DCs elicited 50-fold stronger IFN-γ secretion from tonsil NK cells than from peripheral blood NK cells; these high IFN-γ concentrations delayed latent EBV antigen expression, inhibit B-cells transformation, and decrease their proliferation during the first week after EBV infection in vitro [86]. Here, IFNG is linked to Epstein-Barr virus infection.
