Abstract : Simple Summary In this review, we summarize the current knowledge concerning the potential roles of “abortive-lytic” replication of EBV in establishing the latent state and its contribution to the tumor microenvironment (TME) and oncogenesis. Particular emphasis is given to discussing how EBV deoxyuridine triphosphate nucleotidohydrolase (dUTPase), an early protein encoded by BLLF3 which possesses novel immunomodulatory properties, may contribute to these processes.
