About Epstein-Barr Virus Epstein-Barr virus (EBV or HHV-4) belongs to the family of Herpesviridae and is known as the cause of infectious mononucleosis. Being able to establish a long-term, latent infection in human B cells, it is prevalent in the adult population (worldwide 90%). The virus is associated with a range of human diseases and cancers, particularly Hodgkin s and Burkitt s lymphoma and nasopharyngal carcinoma. Furthermore, EBV has been described to be the main cause of post-transplant lymphoproliferative disease (PTLD) in immune suppressed transplant patients. Finally, EBV increases the risk of certain autoimmune diseases, especially lupus erythematosus, rheumatoid arthritis and multiple sclerosis. The latent EBV Antigens During latent infection EBV expresses a small number of genes (e.g. EBNA1-3 and LMP1-2). Three major types of latency can be differentiated by their distinct expression patterns and are associated with the various types of diseases and cancer. Both, humoral and cellular (mainly CTL) immune responses play a role in controlling the primary and the latent phases of EBV infection.

Immunotherapy (2010) Testimonials The main focus of my research group at the Charité in Berlin is the development of novel immunotherapeutic approaches against cancer and infectious diseases. For reliable monitoring of tumor and virus specific T-cell responses we have a permanent need for peptides and peptide pools that are produced in a regulated environment for application in a clinical environment. JPT has been a long term and dedicated partner in this regard which continuously works on improving its peptide based services. Prof. Dr. Carmen Scheibenbogen, Charité Berlin, Germany
