The molecular basis for this persistence is largely unknown, but 2 recent studies have given evidence in support of persistent circular HBoV episomes (24-26).
In Burkitt's lymphoma, EBV is typically found in a latent form in the B cells, with its episome expressing a pattern of gene transcripts which are composed of two small RNA molecules (the EBV encoded RNAs--EBERs) and the EB nuclear antigen 1 (EBNA1), so-called type I latency.
Whenever an infected cell divides, the episome makes a copy of itself, and each daughter cell receives one.
Latency is characterized by maintenance of the viral genome as a nonintegrated episome and expression of a limited number of viral genes and microRNAs.
