One hundred and ten skin infections with herpes virus were seen in a uniform group of 1,002 lymphoma-leukaemias dominated by non-Hodgkin's lymphoma (385) and Hodgkin's Disease (327). They appeared with a significantly increased frequency in the course of Hodgkin's Disease, and between the ages of 60 and 69 for the other groups. In the Hodgkin's cases they appeared characteristically during complete remission and in the others during the active phase of their disease. Only exceptionally was there evidence of contact infection. Also these infections seemed mainly due to the re-awakening of a latent virus infection as against a failure of natural defense mechanisms of the organism, which the disease itself and the therapeutic regime might alter in a variable fashion.

Epstein-Barr Virus (EBV) causes infectious mononucleosis in normal adolescents and malignant B lymphocyte proliferation in immune compromised patients, in marmosets, or upon transfer of infected human B lymphocytes into SCID mice. EBV is also etiologically associated with African Burkitt's lymphoma, Hodgkin's Disease, and nasopharyngeal cancer. EBV transformed, latently infected B lymphocytes contain EBV episomes and eight virus encoded proteins. Six are nuclear proteins (EBNAs) and two are the integral membrane proteins, LMP1 and LMP2. These eight proteins are presumed to mediate latent virus infection or B lymphocyte proliferation and are thus under intense scrutiny. Besides EBNA1, which is required for episome maintenance, LMP1 and LMP2, are the two transformation associated proteins that are most consistently detected in EBV related malignancies, and the LMP2 message is the only message detected in PCR analysis of B lymphocytes from individuals harboring EBV latent infections. LMP2 associates with src family tyrosine kinases, a 70 kda cell phosphoprotein, LMP1 and several other unidentified cell proteins. LMP1 is a key mediator of EBV's effects on inducing B lymphocyte activation and adhesion molecules and is a transforming oncogene in rodent fibroblasts. The association of these two EBV encoded membrane proteins could create a macromolecular complex mediating constitutive B lymphocyte activation through normal cell signal transduction pathways. LMP2 might may control activation of lytic replication or down regulate the activation state of EBV infected cells allowing persistence in the human host.

Herpesviruses infect the majority of the human population and can cause significant morbidity and mortality. Herpes simplex virus (HSV) type 1 causes cold sores and herpes simplex keratitis, whereas HSV-2 is responsible for genital herpes. Human cytomegalovirus (HCMV) is the most common viral cause of congenital defects and is responsible for serious disease in immuno-compromised individuals. Epstein-Barr virus (EBV) is associated with infectious mononucleosis and a broad range of malignancies, including Burkitt's lymphoma, nasopharyngeal carcinoma, Hodgkin's disease, and post-transplant lymphomas. Herpesviruses persist in their host for life by establishing a latent infection that is interrupted by periodic reactivation events during which replication occurs. Current antiviral drug treatments target the clinical manifestations of this productive stage, but they are ineffective at eliminating these viruses from the infected host. Here, we set out to combat both productive and latent herpesvirus infections by exploiting the CRISPR/Cas9 system to target viral genetic elements important for virus fitness. We show effective abrogation of HCMV and HSV-1 replication by targeting gRNAs to essential viral genes. Simultaneous targeting of HSV-1 with multiple gRNAs completely abolished the production of infectious particles from human cells. Using the same approach, EBV can be almost completely cleared from latently infected EBV-transformed human tumor cells. Our studies indicate that the CRISPR/Cas9 system can be effectively targeted to herpesvirus genomes as a potent prophylactic and therapeutic anti-viral strategy that may be used to impair viral replication and clear latent virus infection.
