CELLULAR HOMOLOGS IN A NEW SIMIAN HERPESVIRUS

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. AIDS-related Kaposi's sarcoma (KS) is the major AIDS-related malignancy. It is believed that an interaction between the retrovirus, HIV, and the herpesvirus, Kaposi's sarcoma-associated herpesvirus (KSHV), results in disease pathogenesis. KSHV-infection and KSHV-related malignancies are newly emerging diseases which are prevalent in the Mediterranean and Sub-Saharan Africa but are spreading into the U.S. and Europe. It is believed that SRV-2 related retroperitoneal fibromatosis (RF) which is associated with the KSHV-like herpesvirus, RFHVMn, is a unique animal model for understanding the interactions of retroviruses and herpesviruses in the induction of tumorigenesis. Understanding virus transmission and tumor initiation in this animal model would provide unique information concerning both the human and macaque diseases which is an essential prerequisite to developing treatments for KS. In this project, we propose to establish the baseline parameters of the infectious cycle of the macaque RFHV. To determine if this virus plays a role in the development of retroperitoneal fibromatosis (RF) we will characterize its infectious cycles and the perturbation of these cycles by SRV-2 and other immunosuppressive agents. We will study virus transmission and the host response to infection. Study populations will include macaques with either active, latent or experimental infections with RFHV.
