hsv igg antibody inhibits virus detection in csf.before pcr testing of cerebrospinal fluid (csf), laboratory diagnosis of herpes encephalitis (hse) was based on virus isolation from brain biopsy. viral isolation from csf has limited clinical value due to low virus recovery; the cause for which has not been demonstrated.201222841844
reactive benign follicular mucinosis: a report of 2 cases.we report 2 cases of adolescents who developed follicular mucinosis following cutaneous infections. a 17-year-old adolescent boy was evaluated for a 2-week history of erythematous papules and plaques on his face and neck. one month prior to presentation a culture was taken that was positive for methicillin-sensitive staphylococcus aureus-associated impetigo. biopsies from 2 representative lesions demonstrated follicular mucinosis without evidence of folliculotropism or t cell gene rearrangements ...201222838088
serum apoptosis markers in hiv-infected patients with human herpesvirus type 8 and herpes simplex virus type 2 co-infection.this study aimed to examine the influence of human herpesvirus type 8 (hhv-8) and herpes simplex virus type 2 (hsv-2) co-infections on apoptosis serum markers in human immunodeficiency virus (hiv)-infected patients. sera from 110 hiv-infected and 59 hiv-uninfected individuals were analyzed for soluble fas (sfas), sfas ligand (sfasl), caspase-8, and bcl-2. the findings of hiv-infected patients with no co-infection (n = 37), hiv-infected patients with hhv-8 co-infection (n = 22), hiv-infected pati ...201222837067
changes in the soluble mucosal immune environment during genital herpes outbreaks.genital tract secretions provide variable inhibitory activity against herpes simplex virus (hsv) ex vivo. we hypothesize that the anti-hsv activity may prevent the spread of virus from the more commonly affected sites, such as the external genitalia, to the upper genital tract.201222820806
disruption of the p53-p21 pathway inhibits efficiency of the lytic-replication cycle of herpes simplex virus type 2 (hsv-2).cellular p53 and its downstream mediator p21, the major cellular growth suppression and dna repair markers, have recently been implicated in viral amplification. here, we show that herpes simplex virus type 2 (hsv-2) infection of both hct116 p53(+/+)and nih3t3 cells resulted in sustained increases of p21. hsv-2 infection did not increase cellular p53 expression, but led to phosphorylation of this protein at ser20. this phosphorylation was accompanied by the increase of p21 protein levels. furthe ...201222820403
maternal antibodies to infectious agents and risk for non-affective psychoses in the offspring--a matched case-control study.an increasing number of studies suggest that certain maternal infections are associated with non-affective psychoses in the offspring. here we investigated if maternal exposure to toxoplasma gondii, cytomegalovirus (cmv), herpes simplex virus type 1 (hsv-1) or type 2 (hsv-2) prior to delivery was associated with future diagnosis of schizophrenia or other non-affective psychoses in the offspring.201222819777
an effector phenotype of cd8+ t cells at the junction epithelium during clinical quiescence of herpes simplex virus 2 infection.herpes simplex virus 2 infection is characterized by cycles of viral quiescence and reactivation. cd8(+) t cells persist at the site of viral reactivation, at the genital dermal-epidermal junction contiguous to neuronal endings of sensory neurons, for several months after herpes lesion resolution. to evaluate whether these resident cd8(+) t cells frequently encounter hsv antigen even during times of asymptomatic viral infection, we analyzed the transcriptional output of cd8(+) t cells captured b ...201222811543

the 2010 royal australasian college of physicians' policy statement 'circumcision of infant males' is not evidence based.infant male circumcision (mc) is an important issue guided by royal australasian college of physicians (racp) policy. here we analytically review the racp's 2010 policy statement 'circumcision of infant males'. comprehensive evaluation in the context of published research was used. we find that the statement is not a fair and balanced representation of the literature on mc. it ignores, downplays, obfuscates or misrepresents the considerable evidence attesting to the strong protection mc affords ...201222805686
detection of herpes viruses in the cerebrospinal fluid of adults with suspected viral meningitis in malawi.we looked for herpes simplex virus types 1 and 2 (hsv-1 and hsv-2, respectively), varicella zoster virus (vzv), epstein-barr virus (ebv) and cytomegalovirus (cmv) dna in malawian adults with clinically suspected meningitis.201322798048
sperm-mediated host-derived dna transfer as a new mechanism for immune system evasion of sexually transmitted genital tract pathogens.over one century of extensive efforts directed towards investigating the immune response and the immuno-protection associated with sexually transmitted infections have failed to produce any effective vaccines against most of the major pathogens, among them neisseria gonorrhea, herpes simplex virus type 2, and chlamydia trachomatis. attempts to design and develop protective vaccines against them have also yielded disappointing results. it has long been felt that there might be another yet undisco ...201222795612
herpes simplex virus is equipped with rna- and protein-based mechanisms to repress expression of atrx, an effector of intrinsic immunity.intrinsic immunity is a first-line intracellular defense against virus infection, and viruses have evolved mechanisms to counteract it. during herpes simplex virus (hsv) infection, nuclear domain 10 (nd10) components localize adjacent to incoming viral genomes and generate a repressive environment for viral gene expression. here, we found that the nd10 component, alpha-thalassemia/mental retardation syndrome x-linked (atrx) protein, is predicted to be a target of hsv-1 mir-h1 and hsv-2 mir-h6. t ...201222787211

bacterial vaginosis associated with increased risk of female-to-male hiv-1 transmission: a prospective cohort analysis among african couples.bacterial vaginosis (bv), a disruption of the normal vaginal flora, has been associated with a 60% increased risk of hiv-1 acquisition in women and higher concentration of hiv-1 rna in the genital tract of hiv-1-infected women. however, whether bv, which is present in up to half of african hiv-1-infected women, is associated with an increase in hiv-1 transmission to male partners has not been assessed in previous studies.201222745608
intranasal immunization in mice with non-ionic surfactants vesicles containing hsv immunogens: a preliminary study as possible vaccine against genital herpes.the purpose of this study was to investigate the potential of intranasal immunization with non-ionic surfactant vesicles (nisv) containing either the secretory recombinant form of glycoprotein b (gbs) of herpes simplex virus type 1 or a related polylysine reach peptides (dtk) for induction of protective immunity against genital herpes infection in mice. nisv were prepared by lipid film hydration method. the mean diameter of vesicles was around 390 nm for dtk-containing nisv (dtk-nisv) and 320 nm ...201322743007
hsv-2 seroepidemiology and risk factors among iranian women: a time to new thinking.genital herpes is a common sexually transmitted disease in many developed and developing countries mostly caused by herpes simplex virus type 2 (hsv-2). this study determines the prevalence of hsv-2 infection between two groups of women with high and low risk behaviors.201122737421
no association between antibodies to sexually transmitted infections and colorectal hyperplastic polyps in men: minnesota cancer prevention research unit polyp study.oncogenic human papillomaviruses (hpv) are sexually transmitted and linked to several epithelial malignancies, but an association between hpv and colorectal neoplasia is not established. previously, we reported a three-fold increase in the odds of colorectal hyperplastic polyps associated with oncogenic hpv seropositivity in men but detected no hpv dna in colorectal tissues from these same men.201222736792
stat4 regulates antiviral gamma interferon responses and recurrent disease during herpes simplex virus 2 infection.stat4 is an important transcription factor that contributes to the incidence and severity of different autoimmune diseases and is implicated in the antiviral immune responses in mice. in this study, we evaluated the role of stat4 in human and murine herpes simplex virus 2 (hsv-2) infections. we show that stat4 regulates antiviral gamma interferon (ifn-γ) responses and disease severity during chronic hsv-2 infections in humans and vaccine-induced ifn-γ-mediated protection against hsv-2 infection ...201222718836
delayed but effective induction of mucosal memory immune responses against genital hsv-2 in the absence of secondary lymphoid organs.to examine whether local immunization in the absence of secondary lymphoid organs (slos) could establish effective antiviral memory responses in the female genital tract, we examined immunity in the vaginal tracts of ltα-/- mice, ltα-/- spl (splenectomized), and control c57bl/6 (wt) mice. all three groups of mice were immunized intravaginally (ivag) with attenuated thymidine kinase-negative (tk(-)) herpes simplex virus type 2 (hsv-2) and challenged 4-6 weeks later with wild-type (wt) hsv-2. both ...201322718264
prenatal maternal infection, neurodevelopment and adult schizophrenia: a systematic review of population-based studies.disruption of foetal development by prenatal maternal infection is consistent with a neurodevelopmental model of schizophrenia. whether specific prenatal infections are involved, their timing and the mechanisms of any effect are all unknown. we addressed these questions through a systematic review of population-based studies.201322717193
anti-herpes simplex virus efficacies of 2-aminobenzamide derivatives as novel hsp90 inhibitors.after the widespread use of the acyclic purine nucleoside analogues for therapy of herpes simplex virus (hsv) infection since the 1980s, new antiviral strategies are urgently needed to counter the emergence of drug-resistant clinical isolates. in this report, we define the anti-hsv efficacies of three optimized 2-aminobenzamide derivatives in vitro and in vivo. the synthetic analogues snx-25a, snx-2112 and snx-7081, which selectively bind to the n-terminal atp pocket of heat shock protein 90 (hs ...201222704890
effects of valacyclovir on markers of disease progression in postpartum women co-infected with hiv-1 and herpes simplex virus-2.herpes simplex virus type 2 (hsv-2) suppression has been shown to reduce hiv-1 disease progression in non-pregnant women and men, but effects on pregnant and postpartum women have not been described.201222701683
future of an "asymptomatic" t-cell epitope-based therapeutic herpes simplex vaccine.considering the limited success of the recent herpes clinical vaccine trial [1], new vaccine strategies are needed. infections with herpes simplex virus type 1 and type 2 (hsv-1 & hsv-2) in the majority of men and women are usually asymptomatic and results in lifelong viral latency in neurons of sensory ganglia (sg). however, in a minority of men and women hsv spontaneous reactivation can cause recurrent disease (i.e., symptomatic individuals). our recent findings show that t cells from symptoma ...201222701511
mucus-penetrating nanoparticles for vaginal drug delivery protect against herpes simplex virus.incomplete coverage and short duration of action limit the effectiveness of vaginally administered drugs, including microbicides, for preventing sexually transmitted infections. we investigated vaginal distribution, retention, and safety of nanoparticles with surfaces modified to enhance transport through mucus. we show that mucus-penetrating particles (mpps) provide uniform distribution over the vaginal epithelium, whereas conventional nanoparticles (cps) that are mucoadhesive are aggregated by ...201222700955
pathological effect of il-17a-producing tcrγδ(+) t cells in mouse genital mucosa against hsv-2 infection.interleukin (il)-17a is a cytokine that plays an important role in infectious, autoimmune, and inflammatory diseases. in this study, we found that tcrγδ(+)cd4(-)cd8(-) t cells, but not tcrαβ(+)cd4(+) t cells, are the primary producers of il-17a in the genital tract of female mice in the steady-state condition. high mrna levels of il-17a and rorγt were determined in tcrγδ(+) t cells isolated from mouse genital tract but lacked detectable expression of ifnγ, t-bet, and foxp3. il-17a production by ...201222698680
poly (i:c), an agonist of toll-like receptor-3, inhibits replication of the chikungunya virus in beas-2b cells.double-stranded rna (dsrna) and its mimic, polyinosinic acid: polycytidylic acid [poly (i:c)], are recognized by toll-like receptor 3 (tlr3) and induce interferon (ifn)-β in many cell types. poly (i:c) is the most potent ifn inducer. in in vivo mouse studies, intraperitoneal injection of poly (i:c) elicited ifn-α/β production and natural killer (nk) cells activation. the tlr3 pathway is suggested to contribute to innate immune responses against many viruses, including influenza virus, respirator ...201222698190
evaluation of antibodies against glycoprotein d (gd) and glycoprotein g (gg) in hsv-1 infected individuals' serum samples.glycoproteins d (gd) and g (gg) of herpes simplex virus type 1 (hsv-1) are virus envelope glycoproteins that are able to induce hsv-1 antibody production in infected persons. therefore, those proteins could be in interest to develop the serodiagnostic test(s) for hsv antibody detection. the aim of present study was the comparison of anti-gd and anti-gg antibodies in hsv-1 infected individuals' serum samples.201222696877
topical microbicides for prevention of sexually transmitted infections.two decades of research on topical microbicides for prevention of sexually transmitted infections (stis) have had limited success. however, new microbicide randomised controlled trial (rct) data have recently been published; but these have not yet been the subject of a systematic review.201222696373
the risk of mental health disorders among u.s. military personnel infected with human immunodeficiency virus, active component, u.s. armed forces, 2000-2011.mental health disorders (mhd) are reportedly more common among soldiers and airmen with hiv than their seronegative counterparts. this report documents the incidence rates of mhd among hiv-positive members of all service branches and compares the rates to those of two hiv-unexposed control groups: an hsv2-infected group and a group without documented hiv or hsv2 infections. approximately 56 percent of hiv-infected service members received an incident diagnosis of a mhd six months or more after t ...201222694588
hiv delays ifn-α production from human plasmacytoid dendritic cells and is associated with syk phosphorylation.plasmacytoid dendritic cells (pdc) are the major producers of type i interferons (ifns) in humans and rapidly produce ifn-α in response to virus exposure. although hiv infection is associated with pdc activation, it is unclear why the innate immune response is unable to effectively control viral replication. we systematically compared the effect of hiv, influenza, sendai, and hsv-2 at similar target cell multiplicity of infection (m.o.i.) on human pdc function. we found that influenza, sendai, h ...201222693567

herpes simplex virus 2 infection impacts stress granule accumulation.interference with stress granule (sg) accumulation is gaining increased appreciation as a common strategy used by diverse viruses to facilitate their replication and to cope with translational arrest. here, we examined the impact of infection by herpes simplex virus 2 (hsv-2) on sg accumulation by monitoring the localization of the sg components t cell internal antigen 1 (tia-1), ras-gtpase-activating sh3-domain-binding protein (g3bp), and poly(a)-binding protein (pabp). our results indicate tha ...201222623775
entry of herpes simplex virus type 1 (hsv-1) into the distal axons of trigeminal neurons favors the onset of nonproductive, silent infection.following productive, lytic infection in epithelia, herpes simplex virus type 1 (hsv-1) establishes a lifelong latent infection in sensory neurons that is interrupted by episodes of reactivation. in order to better understand what triggers this lytic/latent decision in neurons, we set up an organotypic model based on chicken embryonic trigeminal ganglia explants (tges) in a double chamber system. adding hsv-1 to the ganglion compartment (gc) resulted in a productive infection in the explants. by ...201222589716
herpes simplex virus type 2 infection of human epithelial cells induces cxcl9 expression and cd4+ t cell migration via activation of p38-ccaat/enhancer-binding protein-β pathway.recruitment of cd4(+) t cells to infection areas after hsv-2 infection may be one of the mechanisms that account for increased hiv-1 sexual transmission. lymphocytes recruited by chemokine cxcl9 are known to be important in control of hsv-2 infection in mice, although the underlying mechanism remains to be addressed. based on our observation that cxcl9 expression is augmented in the cervical mucus of hsv-2-positive women, in this study we demonstrate that hsv-2 infection directly induces cxcl9 e ...201222586042
inhibition of herpes simplex virus infection by oligomeric stilbenoids through ros generation.stilbenoids including resveratrol contain the basic structural unit of 1,2-diphenylethylene. naturally occurring stilbenoids have broad structural features due to oligomerization and modifications and some have demonstrated potent biological activities. in an effort to identify bioactive stilbenoids, we screened a group of dimeric and oligomeric stilbenoids against hsv-1 and hsv-2 infection. several trimeric and tetrameric derivatives showed anti-herpetic activity at single digit micromolar conc ...201222584350
biological basis for the protective effect conferred by male circumcision against hiv infection.here we provide an up-to-date review of research that explains why uncircumcised men are at higher risk of hiv infection. the inner foreskin is a mucosal epithelium deficient in protective keratin, yet rich in hiv target cells. soon after sexual exposure to infected mucosal secretions of a hiv-positive partner, infected t-cells from the latter form viral synapses with keratinocytes and transfer hiv to langerhans cells via dendrites that extend to just under the surface of the inner foreskin. the ...201222581866
in vitro and in vivo evaluation of a novel antiherpetic flavonoid, 4'-phenylflavone, and its synergistic actions with acyclovir.the development of therapeutic agents for preventing herpes simplex virus (hsv) infections has become urgently necessary because of the increasing incidence of this virus and its role as a cofactor in the transmission of human immunodeficiency virus infection. we have evaluated the antiviral activities of a series of natural and synthetic flavonoids and found that a synthetic flavonoid, 4'-phenylflavone, showed the highest activity against acyclovir (acv)-sensitive and acv-resistant strains of h ...201222580497
congenital non-central nervous system malformations in cerebral palsy: a distinct subset?the aim of this article was to identify and contrast the subset of children with cerebral palsy (cp) and non-central nervous system (cns) congenital malformations with children with cp but no coexisting non-cns congenital malformations.201222577967
[anti alpha-herpesvirus drugs].therapy for infectious diseases resulting from alpha-herpesvirus infections has been dramatically improved by the development of acyclovir (acv). acv is highly specific against herpes simplex virus type 1(hsv-1), herpes simplex virus type 2 (hsv-2) and varicella-zoster virus (vzv) as acv is specifically phosphorylated by the thymidine kinases (tks) of these viruses. these viral tks are important enzymes for viral replication in vivo; therefore, the growth of tk-deficient mutants is impaired. acv ...201222568134
coinfection with rickettsia helvetica and herpes simplex virus 2 in a young woman with meningoencephalitis.herpes virus type 2 dna was detected by pcr in the cerebrospinal fluid in a young woman presenting with headache, stiff neck and pleocytosis, and serological findings consistent with reactivation. since she was exposed to ticks, lyme disease and tick-borne encephalitis were excluded. further investigation in an ongoing project, using pcr and sequencing of the amplified products, showed the presence of rickettsia helvetica in the cerebrospinal fluid. the bacteria were also isolated in vero cell c ...201122567472
recrudescent herpes labialis mimicking primary herpes labialis in pregnancy.herpes simplex virus (hsv) infection is prevalent worldwide. herpes labialis is caused predominantly by hsv-1, and herpes vulvo-vaginitis is caused predominantly by hsv-2. hsv-2 may result in significant morbidity and mortality for infected neonates exposed during delivery. due to this fact, a large amount of literature exists for hsv-2 but data for hsv -1 is scanty.201022558555
immunization with a highly attenuated replication-competent herpes simplex virus type 1 mutant, hf10, protects mice from genital disease caused by herpes simplex virus type 2.genital herpes is an intractable disease caused mainly by herpes simplex virus (hsv) type 2 (hsv-2), and is a major concern in public health. a previous infection with hsv type 1 (hsv-1) enhances protection against primary hsv-2 infection to some extent. in this study, we evaluated the ability of hf10, a naturally occurring replication-competent hsv-1 mutant, to protect against genital infection in mice caused by hsv-2. subcutaneous inoculation of hf10-immunized mice against lethal infection by ...201222557998
glycoprotein g of herpes simplex virus 2 as a novel vaccine antigen for immunity to genital and neurological disease.the envelope glycoproteins of herpes simplex virus 1 (hsv-1) and hsv-2, with the exception of glycoprotein g, elicit cross-reactive b- and t-cell responses. human vaccine trials, using the cross-reactive glycoproteins b and d, have shown no protection against genital hsv-2 infection or disease. in this study, the mature form of glycoprotein g (mgg-2) of hsv-2 was used for immunization of mice, either alone or in combination with adjuvant cpg, followed by an intravaginal challenge with a lethal d ...201222553328
polymorphisms in toll-like receptor 3 confer natural resistance to human herpes simplex virus type 2 infection.lack of toll-like receptor 3 (tlr3) functional activity predisposes children to human herpesvirus 1 (hsv-1) encephalitis. in this study, we have investigated whether there is any link between tlr3 and adult hsv-2 infection by studying genetic variations in tlr3. the frequency of four single-nucleotide polymorphisms (snps) in the tlr3 gene in 239 patients with genital hsv-2 infection and 162 healthy controls, as well as the impact of these variants on tlr3 gene-expression levels, were compared. t ...201222552940
the roles of self-efficacy and pretest counseling in type 2 herpes simplex virus screening in asymptomatic adults.to evaluate the role of counseling for patients undergoing screening for type 2 herpes simplex virus (hsv-2). using pre- and post-screening questionnaires, we evaluated correlations between demographic factors, measures of self-efficacy and follow-through with the screening test, and willingness to take antiviral medication and share results with sexual partners.201222551336
clinical impact of hsv-1 detection in the lower respiratory tract from hospitalized adult patients.the occurrence and clinical impact of herpes simplex virus (hsv) were evaluated in 342 bronchoalveolar lavage specimens from 237 patients. hsv-1 and hsv-2 were detected in 32.1% and <1% of patients, respectively. a significant difference of hsv-1 prevalence and load was found in relation to admission to intensive care unit, mechanical ventilation and mortality within 28 days; in particular, a viral load ≥10(5) copies/ml bronchoalveolar lavage fluid was significantly associated with critical feat ...201222548647
towards a rational design of an asymptomatic clinical herpes vaccine: the old, the new, and the unknown.the best hope of controlling the herpes simplex virus type 1 and type 2 (hsv-1 and hsv-2) pandemic is the development of an effective vaccine. however, in spite of several clinical trials, starting as early as 1920s, no vaccine has been proven sufficiently safe and efficient to warrant commercial development. in recent years, great strides in cellular and molecular immunology have stimulated creative efforts in controlling herpes infection and disease. however, before moving towards new vaccine ...201222548113

impact of asymptomatic herpes simplex virus-2 infection on t cell phenotype and function in the foreskin.herpes simplex virus type 2 (hsv-2) increases the risk of hiv acquisition in men and overall cd4 t cell density in the foreskin. using tissues obtained during routine male circumcision, we examined the impact of hsv-2 on the function and phenotype of foreskin t cells in ugandan men. hsv-2 infection was predominantly associated with a compartmentalized increase in ccr5 expression by foreskin cd4 t cells, which may contribute to hiv susceptibility.201222516874
glycoprotein b of herpes simplex virus 2 has more than one intracellular conformation and is altered by low ph.the crystal structure of herpes simplex virus (hsv) gb identifies it as a class iii fusion protein, and comparison with other such proteins suggests this is the postfusion rather than prefusion conformation, although this is not proven. other class iii proteins undergo a ph-dependent switch between pre- and postfusion conformations, and a low ph requirement for hsv entry into some cell types suggests that this may also be true for gb. both gb and gh undergo structural changes at low ph, but ther ...201222514344
aptamer that binds to the gd protein of herpes simplex virus 1 and efficiently inhibits viral entry.the ectodomain of the gd protein of herpes simplex viruses (hsvs) plays an important role in viral entry by binding to specific cellular coreceptors and mediating viral entry to the host cells. in the present study, we isolated rna aptamers (aptamer-1 and aptamer-5) that specifically bind to the gd protein of hsv-1 with high affinity and are able to discriminate the gd protein of a different virus, hsv-2. aptamer-1 efficiently interfered with the interaction between the gd protein and the hsv-1 ...201222514343
case-crossover analysis of condom use and herpes simplex virus type 2 acquisition.although growing evidence suggests that condoms offer moderate protection against herpes simplex virus type 2 (hsv-2), inability to control for unknown or unmeasured confounders associated with sexual activity may reduce the accuracy of the estimates. the case-crossover design offers increased control of individual-level confounders, and was thus used with the aim of producing a more accurate estimate of the effect of condom use on hsv-2 acquisition.201222504606
