Cell surface heparan sulfate (HS) serves as an initial receptor for many different viruses, including herpes simplex virus types 1 and 2 (HSV-1 and 2, respectively). Glycoproteins C and B (gC and gB) are the major components of the viral envelope that mediate binding to HS. In this study, purified gB and gC homologous proteins as well as purified HSV-1 and HSV-2 virions were compared for the ab...

BACKGROUND Genital herpes results in considerable morbidity, including risk of neonatal herpes, and is increasingly being caused by Herpes Simplex Virus (HSV) type 1. Possibly children are less often HSV-1 infected, leaving them susceptible until sexual debut. We assessed changes in the Dutch HSV-1 and HSV-2 seroprevalence over time and determinants associated with HSV seropositivity. METHODS...

We have evaluated the potential of conferring protective immunity to herpes simplex virus type 2 (HSV-2) by selectively inducing an HSV-specific CD8(+) cytotoxic T-lymphocyte (CTL) response directed against a single major histocompatibility complex class I-restricted CTL recognition epitope. We generated a recombinant vaccinia virus (rVV-ES-gB498-505) which expresses the H-2Kb-restricted, HSV-1...

We report the clinical case of a genital outbreak with both Herpes Simplex Type 1 (HSV-1) and Herpes Simplex Type 2 (HSV-2) during pregnancy. Herpes was presumptively identified by clinical presentation of lesion and Tzanck smear while serotypes were identified by cell culture and polymerase chain reaction (PCR). This case report highlights the need for increased surveillance of both serotypes ...

Herpes simplex virus 1 (HSV-1) ICP0(-) mutants are interferon-sensitive, avirulent, and elicit protective immunity against HSV-1 (Virol J, 2006, 3:44). If an ICP0(-) mutant of herpes simplex virus 2 (HSV-2) exhibited similar properties, such a virus might be used to vaccinate against genital herpes. The current study was initiated to explore this possibility. Several HSV-2 ICP0(-) mutant viruse...

background and aims: the latency-associated transcript (lat) transcribed by latent herpes simplex virus type-1 in neuron cells are able to influence their host cell pathways. while the most of previous studies were focused on anti-apoptotic effects of lat, our investigation is making an effort to explore lat potency on cell cycle pathway in neuroblastoma cell lines. methods: the evaluation of l...

a complication in the analysis of the role of icp34.5 gene in the herpes simplex virus type-1 (hsv-1) lifecycle is the presence of overlapping antisense gene, open reading frame p (orf p), which is also deleted in hsv-1 icp34.5 negative mutants. a hsv-1 wild type strain (17+) icp34.5/orf p deletion mutant (1716) is totally avirulent in animal models and impaired in a number of in vitro function...

Herpes simplex virus type-1 (HSV-1) and -2 (HSV-2) are highly prevalent global pathogens which commonly cause recurrent oral and genital ulcerations. Less common but more serious complications include meningitis, encephalitis, neonatal infection, and keratitis. HSV-2 infection is a significant driver of the HIV epidemic, increasing the risk of HIV acquisition 3 fold. As current control strategi...

The BglII N fragment of herpes simplex virus type 2 (HSV-2) DNA (approximately 0.58 to 0.63 map unit) was examined for encoded products. Using plasmid pGZ59, which consists of BglII-N cloned in pAT153, in conjunction with hybrid arrested translation, mRNA selection, and in vitro protein synthesis, we found that the major translated product of this region has an approximate molecular weight of 3...

BACKGROUND Previous studies using viral cultures rarely reported herpes simplex virus type 2 (HSV-2) isolation from the mouth. We sought to characterize oral HSV-2 shedding as detected by HSV DNA polymerase chain reaction among HSV-2-seropositive men. METHODS Participants collected daily swabs from oral and anogenital areas for HSV detection with a quantitative polymerase chain reaction assay...
