Epstein-Barr virus (EBV) and Kaposi's sarcoma-associated herpesvirus (KSHV or human herpesvirus 8, HHV-8) are members of gamma-herpes virus family. Both viruses infect to B cells and cause malignancies such as lymphoma. Since EBV and HHV-8 are so-called 'oncovirus', their oncogenecities have been focused in the researches on EBV and KSHV for a long time. EBV was discovered in 1964, whereas KSHV was identified in 1994. However, KSHV was analyzed rapidly in these fifteen years. One of the recent progresses in the research on EBV and KSHV is that virus-encoded small RNAs were identified in their genomes and characterized. EBV is the first human virus in whose genome microRNA was identified. The oncogenecity of EBV and KSHV remains unclear. Here, I discuss the pathogenesis by EBV and KSHV with special reference to recent progress in this field.
