herpesvirus papio 2 encodes a virion host shutoff function.infection of baboons with herpesvirus papio 2 (hvp-2) produces a disease that is similar to human infection with herpes simplex viruses (hsv). molecular characterization of hvp-2 has demonstrated that the virion contains a factor which rapidly shuts off host cell protein synthesis after infection. reduction of host cell protein synthesis occurs in parallel with the degradation of mrna species. a homolog of the hsv virion host shutoff (vhs) gene was identified by southern and dna sequence analysi ...200212490401
the latency-associated gene of herpes simplex virus type 1 (hsv-1) interferes with superinfection by hsv-1.during herpes simplex virus type 1 (hsv-1) lifelong latency in human peripheral sensory ganglia (psg), only the viral latency-associated transcript (lat) gene is expressed. this raises the possibility that this gene is involved in establishment of latency of the virus, its maintenance, or reactivation. here we present data that indicate yet another independent function of the lat gene: interference with hsv-1 superinfection of latently infected neurons. neuronal cells stably expressing the lats ...200212491159

type-specific serologic testing for herpes simplex virus-2.genital herpes due to infection with herpes simplex virus-2 (hsv-2) affects an estimated 60 million adults in the united states. over 90% are unaware of their infection but are at risk of transmitting hsv to partners. this ongoing "silent" disease is responsible for the continued increase in hsv prevalence. the recent advent of type-specific serologic tests has allowed accurate differentiation of hsv-1 and hsv-2 infection. screening of at-risk populations will allow identification of individuals ...200312642003
divergence of reiterated sequences in a series of genital isolates of herpes simplex virus type 1 from individual patients.both serotypes of herpes simplex virus (hsv), hsv-1 and hsv-2, are aetiological agents of genital herpes, although genital herpes caused by hsv-1 recurs less frequently. the hsv-1 genome contains a number of short, tandemly repeated sequences, and some reiterated sequences can serve as sensitive markers for the differentiation of hsv-1 strains. in the present study, variation in reiterations (assumed to be due to different copy numbers of tandemly repeated sequences) was examined in hsv-1 isolat ...200312655092
predicting the emergence of drug-resistant hsv-2: new predictions.mathematical models can be used to predict the emergence and transmission of antiviral resistance. previously it has been predicted that high usage of antivirals (in immunocompetent populations) to treat herpes simplex virus type 2 (hsv-2) would only lead to fairly low levels of antiviral resistance. the hsv-2 predictions were based upon the assumption that drug-resistant strains of hsv-2 would be less infectious than drug-sensitive strains but that the drug-resistant strains would not be impair ...200312659657
progesterone increases susceptibility and decreases immune responses to genital herpes infection.depo-provera, a long-acting progestational formulation, is widely used to facilitate infection of sexually transmitted diseases in animal models. we have previously reported that hormone treatments change susceptibility and immune responses to genital tract infections. in this study we compared the changes in susceptibility of mice to genital herpes simplex virus type 2 (hsv-2) after depo-provera or a saline suspension of progesterone (p-sal). we found that following depo-provera-treatment, mice ...200312663762
herpes simplex virus type 2 and heterosexual spread of human immunodeficiency virus infection in developing countries: hypotheses and research priorities.herpes simplex virus type 2 (hsv-2) infection is almost always sexually transmitted, and causes genital ulceration. significant progress in our understanding of hsv infection has occurred over the last decade, in part related to the development of accurate and sensitive laboratory tests to study hsv-2. the application of pcr and type-specific serology to individual cases and in population-based studies has enabled the identification of a potentially important role for hsv-2 infection as a cofact ...200312667248
synthesis of novel apionucleosides: a short and concise synthesis of 2-deoxyapio-l-furanosyl acetate from d-lactose.a series of 2'-deoxyapio-l-furanosyl pyrimidine nucleosides were efficiently synthesized starting from d-lactose via condensation of lactitor acetates with silylated pyrimidine bases under standard vorbrüggen conditions. their structures were determined by 1d and 2d nmr spectroscopy. all the synthesized nucleosides were assayed against several viruses such as hiv-1, hbv, hsv-1, hsv-2, and hcmv. however, none of these compounds had any significant antiviral activity at concentrations up to 100 mi ...200312668089

incidence and prevalence of herpes simplex virus type 2 infection in persons seeking repeat hiv counseling and testing.voluntary hiv testing sites provide an opportunity to identify and counsel persons with herpes simplex virus type 2 (hsv-2) infection, thereby enhancing the prevention of hsv-2 and hiv infections. goal and study design: using serologic specimens left over from hiv testing, we measured hsv-2 prevalence and incidence among persons who had repeatedly tested for hiv at anonymous counseling and testing sites in san francisco during the period october 1997 through march 2000.200312671554
structure-activity relationships of (s,z)-2-aminopurine methylenecyclopropane analogues of nucleosides. variation of purine-6 substituents and activity against herpesviruses and hepatitis b virus.a series of 13 new (s,z)-2-aminopurine methylenecyclopropane analogues was synthesized, and their antiviral activity was investigated. the nucleophilic displacement of chlorine of 2-amino-6-chloropurine derivative 5 with allyl-, propargyl-, cyclopropylmethyl-, isopropyl-, benzyl-, cyclohexyl-, and 2-hydroxyethylamine gave n(6)-alkyl compounds 2a, 2b, 2c, 2d, 2e,2f, and 2g. a similar reaction of 5 with allyl, cyclopropylmethyl, propyl, or pentyl alcohol catalyzed by k(2)co(3) afforded o(6)-alkyl ...200312672254
genotyping of dna using sequence-specific methyltransferases followed by immunochemical detection.modern molecular genetics relies on the ability to map the positions of genes on chromosomes, relative to known dna markers. the first such dna markers described were restriction fragment length polymorphisms, but any restriction endonuclease used for rflp mapping is just one member of a restriction-modification pair. for each restriction endonuclease, there is a companion methyltransferase (mtase) that has the same dna sequence specificity. therefore, in principle, it should be possible to use ...200312680604
rapid detection of herpes simplex virus and varicella-zoster virus infections by real-time pcr.the herpes simplex viruses types 1 and 2 (hsv-1 and hsv-2) and varicella-zoster virus (vzv) can cause life-threatening infections of the central nervous system and lead to severe infections in immunocompromised subjects and newborns. in these cases, rapid diagnosis is crucial. we developed three different real-time pcr assays based on taqman chemistry for the lightcycler instrument to detect hsv-1, hsv-2, and vzv. when the taqman assays were compared to our in-house nested pcr assays, the test s ...200312682146
t cell immunity to herpes simplex viruses in seronegative subjects: silent infection or acquired immunity?during the course of investigating t cell responses to hsv among volunteers entering trials of investigational genital herpes vaccines, 6 of the 24 immunocompetent subjects with no prior history of oral/labial or genital herpes possessed hsv-specific t cell immunity but, by multiple determinants of even the most sensitive serological assays, remained seronegative to hsv-1 and -2. of these six immune seronegative (is; hsv-seronegative with hsv-specific t cell responses) subjects, two had transien ...200312682275
isolation and characterization of a sulfated polysaccharide from the brown alga sargassum patens and determination of its anti-herpes activity.bioactivity-guided fractionation of the hot water extract from the brown alga sargassun patens led to the isolation of a polysaccharide as an antiviral component against herpes simplex viruses which are the cause of cold sores (hsv-1) and genital herpes (hsv-2). the polysaccharide contained a sulfur group that could be present as a sulfate ester. it is thus a sulfated polysaccharide with a molecular mass of about 424 kda, and is designated sp-2a. gas chromatographic assay showed that the polysac ...200312683633
