Furthermore, we examined splenocytes from Ctrl and KO mice for the expression of genes associated with lytic infection (Orf50, Orf68) or latent infection (Orf73), and observed no differences in the relative expression of Orf50, Orf68, or Orf73 between Ctrl and KO mice (Fig. 4F). The gene discussed is CTRL; the disease is disease arising from reactivation of latent virus.
