The SF strain of human herpesvirus 6 (HHV-6SF) isolated from the saliva of a human immunodeficiency virus (HIV)-infected individual was shown to inhibit HIV type 1 (HIV-1) replication in both peripheral blood mononuclear cells and purified CD4+ lymphocytes. This suppression of HIV-1 replication led to decreased cytopathic effects of HIV-1 and prolonged survival of CD4+ cells in culture. Even low levels of HHV-6 added to peripheral blood mononuclear cells showed an inhibitory effect on HIV-1 replication. These results differ from those previously reported showing enhanced HIV-1 production following infection with another strain of HHV-6.

UI	MeSH Term	Description	Entries
D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell

D014762	Viral Interference	A phenomenon in which infection by a first virus results in resistance of cells or tissues to infection by a second, unrelated virus.	Interference, Viral,Interferences, Viral,Viral Interferences
D014779	Virus Replication	The process of intracellular viral multiplication, consisting of the synthesis of PROTEINS; NUCLEIC ACIDS; and sometimes LIPIDS, and their assembly into a new infectious particle.

D015497	HIV-1	The type species of LENTIVIRUS and the etiologic agent of AIDS. It is characterized by its cytopathic effect and affinity for the T4-lymphocyte.	Human immunodeficiency virus 1,HIV-I,Human Immunodeficiency Virus Type 1,Immunodeficiency Virus Type 1, Human
D015654	Herpesvirus 6, Human	Members of the ROSEOLOVIRUS genus of the Betaherpesvirales subfamily isolated from patients with AIDS and other LYMPHOPROLIFERATIVE DISORDERS. It infects and replicates in fresh and established lines of hematopoietic cells and cells of neural origin. It also appears to alter the activity of NK CELLS. HHV-6; (HBLV) antibodies are elevated in patients with AIDS; SJOGREN'S SYNDROME; SARCOIDOSIS; CHRONIC FATIGUE SYNDROME, and certain malignancies. HHV-6A is the most common cause of EXANTHEMA SUBITUM and has been implicated in encephalitis. When HHV-6 integrates into the host genome it is referred to as ciHVH-6. When such VIRUS INTEGRATION occurs into the germline it is referred to as iciHHV-6.
