Lymphomas are solid tumors consisting of lymphoid cells; they form a heterogeneous group of less or more malignant disorders. A portion of lymphomas develop due to latent herpesvirus infections established in B and/or T-lymphocytes. The basis for latency is a lifelong presence of the circularized covalently linked viral genome within nuclei of carrier lymphocytes. In certain cases, however, the essential event leading to tumor formation is the integration of a portion(s) of viral DNA into the host cell DNA. This leads to rearrangements within the host cell genome on one hand, and, on other hand, to unregulated expression of oncoproteins encoded by the integrated fragment. Our review deals with mechanisms of lymphoma formation regarding to the role of non-structural herpesvirus oncoproteins interfering with the regulation of cell division and/or exerting anti-apoptotic effects. In addition, the authors wish to highlight the common procedures, which allowed isolation and/or identification of lymphoma-associated viruses in cell cultures derived from tumors and/or proliferating lymphatic tissues.
