CD34 and disease arising from reactivation of latent virus: Using input RNA from UV inactivated virus as reference level, Fig. 2a shows that most viral miRNAs could be detected in latently infected cells at levels well above levels detected in cells infected with UV-inactivated virus controls at 4 dpi, confirming that the viral miRNAs identified after latent infection of CD34+ cells and monocytes were expressed de novo during latent infection.
