Good morning, I think how EBV can modify the activity of Lymphocytes B so CMV with other cells. I do not think well yet in which cells the CMV is inserted and how the immune system reacts sharply and over time, even when the herpes virus is reactivated. It is known that juvenile diabetes develops after an intestinal viral infection with an alteration of phenotypic tolerance to pancreatic cells (reduction of Tregulators, FOXP3 + Lymphocytes, increase M1).
