Transactivation of human immunodeficiency virus promoter by human herpesvirus 6.
Patients with acquired immunodeficiency syndrome (AIDS) are often infected with a number of other heterologous viruses in addition to the initial human immunodeficiency virus (HIV) infection, and these agents could act as potential reactivating agents of latent HIV. A new antigenically distinct herpesvirus, designated human herpesvirus 6 (HHV-6), has recently been isolated from patients with AIDS and has been shown to infect a number of different human cells, specifically human T cells, B cells, and glial cells. Since these are some of the same cells that harbor the AIDS virus, it is quite important to determine any interaction between this new herpesvirus and HIV. In this report, we demonstrate that HHV-6 can trans-activate the HIV promoter in human T-cell lines as measured by the expression of the bacterial gene chloramphenicol acetyltransferase. This indicates that stimulation of HIV gene expression by HHV-6 could play a role in HIV pathogenesis.
