safety and immunogenicity of a glycoprotein d genital herpes vaccine in healthy girls 10-17 years of age: results from a randomised, controlled, double-blind trial.the investigational as04-adjuvanted herpes simplex virus type 2 (hsv-2) glycoprotein d (gd2) subunit prophylactic vaccine ('hsv vaccine'; glaxosmithkline vaccines) has been shown to be well tolerated in adults, but limited data exist for pre-teen and adolescent girls, a likely target population. the primary objective of this study was to compare the occurrence of serious adverse events (saes) over 12 months between hsv vaccine recipients and saline recipients (placebo control group) in pre-teen ...201323850416
adenovirus-mediated shrna interference against hsv-1 replication in vitro.the ul29 and ul28 proteins encoded by herpes simplex virus type 1 (hsv-1) are critical for its replication and packaging, respectively. research has demonstrated that synthesized sirna molecules targeting the ul29 gene are able to suppress hsv-2 replication and the ul28-null hsv-1 gene cannot form infectious viruses in vitro. silencing the ul28 and ul29 genes by rnai might lead to the development of novel antiviral agents for the treatment of hsv-1 infections. two kinds of short hairpin rnas (sh ...201627566181
predictors of hvtn 503 mrk-ad5 hiv-1 gag/pol/nef vaccine induced immune responses.phambili, the merck (mrk)-adenovirus type 5 (ad5) hiv-1 gag/pol/nef subtype b vaccine study, conducted in south africa, suspended enrollment and vaccination when companion study, step, was found non-efficacious. although the vaccine did not prevent hiv-1 infection or lower viral-load setpoint, immune responses recognized clades b and c hiv-1 subtypes. we investigated predictors of the vaccine-induced antigen-specific immune responses.201425090110
targeting the genital tract mucosa with a lipopeptide/recombinant adenovirus prime/boost vaccine induces potent and long-lasting cd8+ t cell immunity against herpes: importance of myd88.targeting of the mucosal immune system of the genital tract with subunit vaccines has failed to induce potent and durable local cd8(+) t cell immunity, which is crucial for protection against many sexually transmitted viral pathogens, including hsv type 2 (hsv-2), which causes genital herpes. in this study, we aimed to investigate the potential of a novel lipopeptide/adenovirus type 5 (lipo/radv5) prime/boost mucosal vaccine for induction of cd8(+) t cell immunity to protect the female genital t ...201223018456
atypical herpetic whitlow: a diagnosis to consider.herpetic whitlow is caused by herpes virus (type1 or 2) during primary infection or as result of autoinoculation. commonly, it is caused by hsv-2 in adults with positive history for genital infection. we report a rare case of herpetic whitlow that should be kept in mind by physicians in recurrent cases of fingers infection. advanced diagnostic techniques as pcr are required to help clinicians to achieve a definite diagnosis and to choose the right treatment.201728376707
leflunomide in the treatment of a pseudotumoral genital herpes simplex virus infection in an hiv patient.the patient is a 52-year-old african american man with a past medical history of hiv infection (on antiretroviral therapy, cd4 count 399 cells/µl, and undetectable hiv viral load) and recurrent genital herpes. while on valacyclovir, the patient presented with four tumorous lesions on the perineum and scrotum. a biopsy specimen stained positively with hsv-1 and hsv-2 immunostains and displayed a lymphoplasmacytic infiltrate. the patient received foscarnet and imiquimod for two weeks with minimal ...201728373917
ancient recombination events between human herpes simplex viruses.herpes simplex viruses 1 and 2 (hsv-1 and hsv-2) are seen as close relatives but also unambiguously considered as evolutionary independent units. here, we sequenced the genomes of 18 hsv-2 isolates characterized by divergent ul30 gene sequences to further elucidate the evolutionary history of this virus. surprisingly, genome-wide recombination analyses showed that all hsv-2 genomes sequenced to date contain hsv-1 fragments. using phylogenomic analyses, we could also show that two main hsv-2 line ...201728369565

peptides derived from glycoproteins h and b of herpes simplex virus type 1 and herpes simplex virus type 2 are capable of blocking herpetic infection in vitro.the aim of this study was to design peptides derived from glycoproteins h (gh) and b (gb) of herpes simplex viruses type 1 (hsv-1) and type 2 (hsv-2) with the potential to block herpetic infection and to evaluate their ability to inhibit hsv-1 and hsv-2 infection in vitro.201728329739
antiviral activity of pha767491 against human herpes simplex virus in vitro and in vivo.herpes simplex virus (hsv) is a common human pathogen that causes a variety of diseases, including oral-labial, genital lesions and life-threatening encephalitis. the antiviral nucleoside analogues such as acyclovir are currently used in anti-hsv therapies; however, clinical overuse of these drugs has led to the emergence of drug-resistant viral strains. hence, there is an urgent need to develop new anti-hsv agents.201728320320
worldwide circulation of hsv-2 × hsv-1 recombinant strains.homo sapiens harbor two distinct, medically significant species of simplexviruses, herpes simplex virus (hsv)-1 and hsv-2, with estimated divergence 6-8 million years ago (mya). unexpectedly, we found that circulating hsv-2 strains can contain hsv-1 dna segments in three distinct genes. using over 150 genital swabs from north and south america and africa, we detected recombinants worldwide. common, widely distributed gene ul39 genotypes are parsimoniously explained by an initial >457 basepair (b ...201728287142
the product of the herpes simplex virus type 2 ul16 gene is critical for the egress of capsids from the nuclei of infected cells.the herpes simplex virus (hsv) ul16 gene is conserved throughout the herpesviridae and encodes a poorly understood tegument protein. the hsv-1 ul16 protein forms complexes with several viral proteins including ul11, ge, vp22 and ul21. we previously demonstrated that hsv-2 ul21 was essential for virus propagation due to the failure of dna-containing capsids to exit the nucleus. we hypothesized that if a ul16/ul21 complex were required for nuclear egress then hsv-2 lacking ul16 would have a simila ...201728275195
linear multiepitope (glyco)peptides for type-specific serology of herpes simplex virus (hsv) infections.detection of type-specific antibodies is an important and essential part of accurate diagnosis, even in silent carriers of herpes simplex virus (hsv)-1 (oral) and hsv-2 (genital) infections. serologic assays that identify hsv-1 and hsv-2 type-specific antibodies have been commercially available for more than a decade but often face problems related to cross-reactivity and similar issues. attempts to identify type-specific peptide epitopes for use in serology for both hsv-1 and hsv-2 have been li ...201728238255
