Concurrent Expression of Latent and a Limited Number of Lytic Genes with Immune Modulation and Antiapoptotic Function by Kaposi's Sarcoma-Associated Herpesvirus Early during Infection of Primary Endothelial and Fibroblast Cells and Subsequent Decline of Lytic Gene Expression

Abstract excerpt

Kaposi's sarcoma-associated herpesvirus (KSHV) infection of in vitro target cells is characterized by the expression of the latency-associated open reading frame (ORF) 73 gene (LANA-1) and the absence of progeny virus production. This default latent infection can be switched into lytic cycle by phorbol ester and by the lytic cycle ORF 50 (RTA) protein. In this study, the kinetics of latent and lytic gene...
