IFN-γ-mediated inhibition of γHV68 reactivation acts during viral reactivation ex vivo. (A) Ex vivo reactivation stopped at various days by three freeze-thaw cycles. The statistical significance of the difference between unfrozen and frozen results on day 0, day 2, and day 4 is P = 0.015. (B) Ex vivo reactivation after addition of IFN-γ at various days. The statistical significance of the difference between medium and day 0, day 1, and day 2 is P = 0.001, P = 0.02, P = 0.04, respectively. n, number of independent experiments.
