A Gammaherpesvirus MicroRNA Targets EWSR1 (Ewing Sarcoma Breakpoint Region 1) In Vivo To Promote Latent Infection of Germinal Center B Cells.

ABSTRACT: Gammaherpesviruses, including the human pathogens Epstein-Barr virus (EBV) and Kaposi's sarcoma-associated herpesvirus (KSHV), directly contribute to the genesis of multiple types of malignancies, including B cell lymphomas. In vivo, these viruses infect B cells and manipulate B cell biology to establish lifelong latent infection. To accomplish this, gammaherpesviruses employ an array of gene products, including microRNAs (miRNAs). Although numerous host mRNA targets of gammaherpesvirus miRNAs have been identified, the in vivo relevance of repression of these targets remains elusive due to species restriction. Murine gammaherpesvirus 68 (MHV68) provides a robust virus-host system to dissect the in vivo function of conserved gammaherpesvirus genetic elements. We identif
