Dr. Rose’s and his lab’s research is focused on herpesviruses implicated in cellular transformation and tumor induction, and in the study of host and viral proteins that mediate these effects. In particular, they are studying the viral etiology of Kaposi’s sarcoma (KS) and other AIDS-related malignancies with regards to the interactions between viruses (retroviruses and herpesviruses) and cytokines in virus activation and tumor induction. Their research focuses on the Kaposi’s sarcoma-associated herpesvirus (KSHV) and its homologs in non-human primates. They discovered the macaque homolog of KSHV and are studying its association with a Kaposi’s sarcoma-like malignancy in macaques, called retroperitoneal fibromatosis (RF), which like AIDS-KS is associated with a retrovirus infection. RF occurs in conjunction with simian AIDS (SAIDS) caused by infection with simian retrovirus 2 (SRV2) or SIV, the simian homolog of HIV. They have identified a second lineage of KSHV-like rhadinoviruses in macaques and are studying its role in RF and other macaque tumors. Ongoing projects include the cloning and sequence of the genome of the new macaque herpesvirus, the identification and characterization of cellular receptors mediating infection by KSHV, the comparative analysis of KSHV and its simian homologs and their role in tumor induction in association with HIV-induced immunosuppression, the characterization of latency and the activating switch to herpesvirus replication, and the development of diagnostic tests for novel viruses.
