Cytolytic virus activation therapy for Epstein-Barr virus-driven tumors.

PURPOSE Nasopharyngeal carcinoma (NPC) is causally linked to Epstein-Barr virus (EBV) infection. Because all tumor cells carry EBV, the virus itself is a potential target for therapy. In these tumor cells, EBV hides in a latent state and expresses only a few non-immunogenic proteins for EBV maintenance and contributes to tumor growth. We developed a cytolytic virus activation (CLVA) therapy for...

Cytolytic virus activation therapy and treatment monitoring for Epstein‐Barr virus associated nasopharyngeal carcinoma in a mouse tumor model

Undifferentiated nasopharyngeal carcinoma (NPC) is 100% associated with Epstein-Barr virus (EBV). Expression of viral proteins in the tumor cells is highly restricted. EBV reactivation by CytoLytic Virus Activation (CLVA) therapy triggers de novo expression of early viral kinases (PK and TK) and uses antiviral treatment to kill activated cells. The mechanism of tumor elimination by CLVA was ana...

THE IN VITRO GROWTH PROPERTIES OF CELL LINES FROM EPSTEIN-BARR VIRUS-INDUCED TAMARIN TUMORS AND TAMARIN B CELLS TR ANSFORMED BY EPSTEIN BARR VIRUS

EBV-carrying human cell lines, depending on whether the cells are derived from Burkitt's lymphoma (BL) tumor biopsies or transformed by EBV in vitro, have different growth properties in vitro. In contrast, there are no clear differences between tamarin tumor lines and tamarin LCLs in vitro. Both types of tamarin cell lines could grow in agarose and formed colonies unlike human LCLs, althoug...

Epstein-Barr Virus (Infectious Disease and Therapy)

Epstein-Barr virus (EBV) was the first recognized human tumor virus, but it is not the causative agent for the tumor in which it was discovered, Burkitt lymphoma. Common to all Burkitt lymphomas, endemic or sporadic, are distinctive chromosomal translocations that reactivate expression of the c-myc protooncogene and comprise the primary oncogenic mechanism. EBV is at least a contributory cofact...

Epstein-Barr Virus Behavior in Different Populations and Implications for Control of Epstein-Barr Virus-associated Tumors

The epidemiology of Epstein-Barr virus (EBV) infection in populat ions at dif ferent risk for EBV-associated diseases indicates signif icant differences between the populat ions. EBV infection takes place much earlier in Uganda, where all chi ldren are infected before the age of 2 to 3 years, than in Southeast Asia, where nasopharyngeal carcinoma is prevalent. It is proposed that such early inf...
