Human herpesviruses (HHVs) are widespread infectious pathogens that have been associated with proliferative and inflammatory diseases. During viral evolution, HHVs have pirated genes encoding viral G protein-coupled receptors (vGPCRs), which are expressed on infected host cells. These vGPCRs show highest homology to human chemokine receptors, which play a key role in the immune system. Importan...
The relationship between thymidine kinase (TK) activity and virulence was studied in the mouse using three HSV-1 strains: (1) NIH TK+ (100% activity), (2) NIH TK+/- (25% TK activity), and (3) NIH TK- (0% TK activity). Following corneal inoculation, keratitis, virus titers (eye, trigeminal ganglia brain), survival, and latency were determined for each strain. The most virulent strain, NIH TK+ (3...
BACKGROUND Randomized trials show that male circumcision (MC) reduces the incidence of HIV and herpes simplex virus type 2 (HSV-2) infections, and symptomatic genital ulcer disease (GUD). We assessed the role of GUD and HSV-2 in the protection against HIV afforded by MC. METHODS AND FINDINGS HIV-uninfected men were randomized to immediate (n = 2,756) or delayed MC (n = 2,775) in two randomize...
C A S E A previously healthy 25-day-old boy presented to a tertiary children’s hospital with a diffuse vesicular rash worsening over the previous 2 weeks. Per parental report, the rash was not accompanied by any other symptoms and did not appear to be pruritic or painful; specifically, he had no history of fever and was formula feeding well. The infant was the product of a full-term pregnancy, ...
The cytotoxic effects of acyclovir, which is a purine nucleoside analogue and is known as an antibiotic substance, were examined on three lines of rat skin fibroblast FR cells; normal FR cells, FRtk- cells which are deficient in the activity of thymidine kinase (tk) and FRtk-HSVtk+ cells which were prepared by introducing herpes simplex virus' tk gene to FRtk- cells. When FRtk-HSVtk+ cells grow...
Prospects for the development of vaccines against herpes simplex virus types 1 and 2 and other herpesvirus group vaccines are discussed from the scientific, medical, and economic standpoints. Probably, the most practical development will be glycoprotein subunit vaccines, prepared from herpes simples virus types 1 and 2, that will be tested for prophylaxis and therapy of acute viral disease and ...
BACKGROUND Previously we conducted a double-blind controlled, randomized efficacy field trial of gD-2 HSV vaccine adjuvanted with ASO4 in 8323 women. Subjects had been previously selected to be seronegative for HSV-1 and HSV-2. We found that vaccine was 82% protective against HSV-1 genital disease, but offered no significant protection against HSV-2 genital disease. METHODS To better understa...
Mathematical models are useful tools for summarizing and testing current knowledge about a system and predicting trends. Models have shown that medical and behavioural changes can substantially affect herpes simplex virus type 2 (HSV-2) transmission and can be used to develop rational epidemic control policies. The spread of the genital herpes epidemic and the potential impact of HSV antiviral ...
BACKGROUND This study aimed to identify the characteristics of HIV and herpes simplex virus (HSV)-2 seroprevalence in male patients with anal disease. METHODS HIV seroprevalence was estimated for different age groups of male patients with anal disease who were treated at Songdo colorectal hospital in Korea between 2001 and 2011. HIV seroprevalence of patients with anal disease was compared wi...
The UL9 gene of herpes simplex virus type 1 (HSV-1) encodes an origin binding protein (OBP). It is an ATP-dependent DNA helicase and a sequence-specific DNA-binding protein. The latter function is carried out by the C-terminal domain of OBP (DeltaOBP). We have now performed a quantitative analysis of the interaction between DeltaOBP and its recognition sequence, GTTCGCAC, in oriS. Initially opt...
