| first description of herpes simplex virus type 1 epididymo-orchitis: a new clinical form of herpes simplex virus infection during septic shock? | genital herpes is increasingly caused by herpes simplex virus type 1 (hsv-1), but recurrences are less frequent than with hsv-2. distinguishing between primary genital infection and reactivation can be difficult, but hsv-1 more often causes severe primary infections and fewer recurrences. however, as virus reactivation is common during septic shock, a severe form of hsv-1 reactivation can occur in locations other than the lungs, which remain the most common site. the case of a 79-year-old caucas ... | 2016 | 27672563 |
| medroxyprogesterone acetate and levonorgestrel increase genital mucosal permeability and enhance susceptibility to genital herpes simplex virus type 2 infection. | depot-medroxyprogesterone acetate (dmpa) is a hormonal contraceptive especially popular in areas with high prevalence of hiv and other sexually transmitted infections (sti). although observational studies identify dmpa as an important sti risk factor, mechanisms underlying this connection are undefined. levonorgestrel (lng) is another progestin used for hormonal contraception, but its effect on sti susceptibility is much less explored. using a mouse model of genital herpes simplex virus type 2 ( ... | 2016 | 27007679 |
| bacterial vaginosis: a synthesis of the literature on etiology, prevalence, risk factors, and relationship with chlamydia and gonorrhea infections. | bacterial vaginosis (bv) is a common vaginal disorder in women of reproductive age. since the initial work of leopoldo in 1953 and gardner and dukes in 1955, researchers have not been able to identify the causative etiologic agent of bv. there is increasing evidence, however, that bv occurs when lactobacillus spp., the predominant species in healthy vaginal flora, are replaced by anaerobic bacteria, such as gardenella vaginalis, mobiluncus curtisii, m. mulieris, other anaerobic bacteria and/or m ... | 2016 | 26877884 |
| ifn-ε protects primary macrophages against hiv infection. | ifn-ε is a unique type i ifn that is not induced by pattern recognition response elements. ifn-ε is constitutively expressed in mucosal tissues, including the female genital mucosa. although the direct antiviral activity of ifn-ε was thought to be weak compared with ifn-α, ifn-ε controls chlamydia muridarum and herpes simplex virus 2 in mice, possibly through modulation of immune response. we show here that ifn-ε induces an antiviral state in human macrophages that blocks hiv-1 replication. ifn- ... | 2016 | 27942584 |
| complement opsonization promotes herpes simplex virus 2 infection of human dendritic cells. | herpes simplex virus 2 (hsv-2) is one of the most common sexually transmitted infections globally, with a very high prevalence in many countries. during hsv-2 infection, viral particles become coated with complement proteins and antibodies, both present in genital fluids, which could influence the activation of immune responses. in genital mucosa, the primary target cells for hsv-2 infection are epithelial cells, but resident immune cells, such as dendritic cells (dcs), are also infected. dcs ar ... | 2016 | 26937039 |
| prevalence of herpes simplex virus 2 (hsv-2) infection and associated risk factors in a cohort of hiv negative women in durban, south africa. | herpes simplex virus 2 (hsv-2) is one of the most common sexually transmitted infections (stis) worldwide and is a risk factor for the acquisition and transmission of other stis, including hiv. we determined the prevalence and predictors of hsv-2 infection among women screened for a hiv prevention trial in durban, south africa. univariate and multivariate logistic and cox regression models were used to determine the correlates and predictors of hsv-2 infection at enrolment and seroconversion dur ... | 2016 | 27955706 |
| evolution of rational vaccine designs for genital herpes immunotherapy. | immunotherapeutic vaccines have emerged as a novel treatment modality for genital herpes, a sexually transmitted disease mainly caused by herpes simplex virus type 2. the approaches to identify potential vaccine antigens have evolved from classic virus attenuation and characterization of antibody and t cell responses in exposed, but seronegative individuals, to systematic screens for novel t cell antigens. combined with implementation of novel vaccine concepts revolving around immune evasion and ... | 2016 | 26896782 |
| parents' reactions to testing for herpes simplex virus type 2 as a biomarker of sexual activity in botswana junior secondary school students. | background use of sexual activity biomarkers in hiv prevention trials has been widely supported to validate self-reported data. when such trials involve minors, researchers may face challenges in obtaining parental buy-in, especially if return of results procedures uphold the confidentiality and privacy rights of minors and preclude parental access to test results. in preparation for a randomised controlled trial (rct) with junior secondary school (jss) students in botswana, a formative assessme ... | 2016 | 26886026 |
| treatment of colon cancer with oncolytic herpes simplex virus in preclinical models. | cancer stem cells (cscs), which are a rare population in any type of cancer, including colon cancer, are tumorigenic and responsible for cancer recurrence and metastasis. cscs have been isolated from a number of different solid tumors recently, although the isolation of cscs in colon cancer is still challenging. we cultured colon cancer cells in stem cell medium to obtain colonosphere cells. these cells possessed the characteristics of cscs, with a high capacity of tumorigenicity, migration and ... | 2016 | 26871935 |
| incidence of co-infections of hiv, herpes simplex virus type 2 and syphilis in a large cohort of men who have sex with men in beijing, china. | the hiv-epidemic among msm in china has worsened. in this key population, prevalence of hsv-2 and syphilis infection and co-infection with hiv is high. | 2016 | 26820145 |
| dysbiosis-induced il-33 contributes to impaired antiviral immunity in the genital mucosa. | commensal microbiota are well known to play an important role in antiviral immunity by providing immune inductive signals; however, the consequence of dysbiosis on antiviral immunity remains unclear. we demonstrate that dysbiosis caused by oral antibiotic treatment directly impairs antiviral immunity following viral infection of the vaginal mucosa. antibiotic-treated mice succumbed to mucosal herpes simplex virus type 2 infection more rapidly than water-fed mice, and also showed delayed viral cl ... | 2016 | 26811463 |
| oasl1 deficiency promotes antiviral protection against genital herpes simplex virus type 2 infection by enhancing type i interferon production. | type i interferon (ifn) interferes with virus replication, promotes antiviral responses, and controls innate and adaptive immune responses to certain viruses. recently, we reported that 2'-5' oligoadenylate synthetase-like 1 (oasl1) negatively regulates type i ifn production by inhibiting the translation of the type i ifn-regulating master transcription factor, irf7. notably, while oasl1-deficient mice induce robust production of type i ifn and are resistant to systemic viral infection, the effe ... | 2016 | 26750802 |
| sustained high prevalence of viral hepatitis and sexually transmissible infections among female sex workers in china: a systematic review and meta-analysis. | the 1980's economic boom has been associated with a rapid expansion of china's sex industry over the past three decades. consequently, the spread of sexually transmitted infections (stis) and hepatitis infections among female sex workers (fsw) has become an important public health issue in china. this study identifies prevalence and risks of hepatitis and stis in chinese fsws. | 2016 | 26732281 |
| genital herpes simplex virus type 2 shedding among adults with and without hiv infection in uganda. | despite the high prevalence of herpes simplex virus type 2 (hsv-2) in sub-saharan africa, the natural history of infection among africans is not well characterized. we evaluated the frequency of genital hsv shedding in hiv-seropositive and hiv-seronegative men and women in uganda. | 2016 | 26486633 |

| herpes simplex virus type 2: cluster of unrelated cases in an intensive care unit. | herpes simplex viruses, which are associated with various clinical manifestations, can be transmitted to critically ill patients from other patients or health care staff. we report an apparent outbreak of mucocutaneous herpes simplex virus 2 infections (5 cases in 10 weeks). an epidemiologic investigation and genotype analysis showed no connections among the 5 cases. | 2016 | 27198455 |
| anti-apoptotic function of herpes simplex virus -2 latency-associated transcript rl1 sequence and screening of its encoded micrornas. | the latency-associated transcript (lat) gene of herpes simplex virus (hsv)-2 is the only detectable viral gene expressed during latent infection in neurons. lat inhibits apoptosis and maintains latency by promoting the survival of infected neurons. however, whether lat functions during hsv-2 infection via its encoded rnas or via its encoded proteins remain unknown. increasing evidence has indicated that lat is likely to functionally promote the establishment of latent infection via lat-encoded m ... | 2016 | 27663158 |
| formative work and community engagement approaches for implementing an hiv intervention in botswana schools. | providing adolescents with evidence-based sexual risk reduction interventions is critical to addressing the hiv/aids epidemic among adolescents in sub-saharan africa. project aim (adult identity mentoring) is an innovative, evidence-based, youth development intervention that is being evaluated for the first time in botswana through a 3-year (2015-2017), 50-school cluster randomized controlled trial, including testing for herpes simplex virus type 2 as a sexual activity biomarker. conducting a tr ... | 2016 | 27196663 |
| herpes simplex virus type 2 seroprevalence and ultrasound-diagnosed uterine fibroids in a large population of young african-american women. | for decades reproductive tract infections (rtis) have been hypothesized to play a role in uterine fibroid development. the few previous studies conducted used self-reported history of rtis and had inconsistent findings. we investigated this hypothesis further using serological analysis, an immunological measure of past exposure. we focused on herpes simplex virus type 2 (hsv-2) because prior published data have suggested a possible association with fibroids, and serology for hsv-2 is much more s ... | 2016 | 27188945 |
| intravaginal zinc oxide tetrapod nanoparticles as novel immunoprotective agents against genital herpes. | virtually all efforts to generate an effective protection against the life-long, recurrent genital infections caused by hsv-2 have failed. apart from sexual transmission, the virus can also be transmitted from mothers to neonates, and it is a key facilitator of hiv coacquisition. in this article, we uncover a nanoimmunotherapy using specially designed zinc oxide tetrapod nanoparticles (zoten) with engineered oxygen vacancies. we demonstrate that zoten, when used intravaginally as a microbicide, ... | 2016 | 27183601 |
| in situ detection of regulatory t cells in human genital herpes simplex virus type 2 (hsv-2) reactivation and their influence on spontaneous hsv-2 reactivation. | herpes simplex virus type 2 (hsv-2) reactivation is accompanied by a sustained influx of cd4(+) and cd8(+) t cells that persist in genital tissue for extended periods. while cd4(+) t cells have long been recognized as being present in herpetic ulcerations, their role in subclinical reactivation and persistence is less well known, especially the role of cd4(+) regulatory t cells (tregs). | 2016 | 27117511 |
| [factors related to syphilis and other infections among female drug users in shandong women's compulsory drug rehabilitation center in 2015]. | objective: to analyze the prevalence of hiv, syphilis and related factors among female drug users in shandong women's compulsory drug rehabilitation center(swcdrc). methods: during may 2015, we used a cluster sampling method for drug users in swcdrc, with a questionnaire and serological testing. we included respondents who volunteered to take part in this study, had clear histories of drug abuse, and had no symptoms of psychosis or current drug use; 451 women participated. the questionnaire addr ... | 2016 | 27655604 |
| immune responses elicited by the gen-003 candidate hsv-2 therapeutic vaccine in a randomized controlled dose-ranging phase 1/2a trial. | gen-003 is a candidate therapeutic hsv-2 vaccine containing a fragment of infected cell protein 4 (icp4.2), a deletion mutant of glycoprotein d2 (gd2δtmr), and matrix-m2 adjuvant. in a dose-ranging phase 1/2a clinical trial, immunization with gen-003 reduced viral shedding and the percentage of reported herpetic lesion days. here we examine the immune responses in the same trial, to characterize vaccine-related changes in antibody and cell-mediated immunity. | 2016 | 27642130 |
| vaccination with the secreted glycoprotein g of herpes simplex virus 2 induces protective immunity after genital infection. | herpes simplex virus 2 (hsv-2) infects the genital mucosa and establishes a life-long infection in sensory ganglia. after primary infection hsv-2 may reactivate causing recurrent genital ulcerations. hsv-2 infection is prevalent, and globally more than 400 million individuals are infected. as clinical trials have failed to show protection against hsv-2 infection, new vaccine candidates are warranted. the secreted glycoprotein g (sgg-2) of hsv-2 was evaluated as a prophylactic vaccine in mice usi ... | 2016 | 27110813 |
| strong country level correlation between syphilis and hsv-2 prevalence. | background. syphilis is curable but herpes simplex virus-2 (hsv-2) is not. as a result, the prevalence of syphilis but not hsv-2 may be influenced by the efficacy of national sti screening and treatment capacity. if the prevalence of syphilis and hsv-2 is found to be correlated, then this makes it more likely that something other than differential sti treatment is responsible for variations in the prevalence of both hsv-2 and syphilis. methods. simple linear regression was used to evaluate the r ... | 2016 | 27069710 |
| no evidence of pritelivir resistance among herpes simplex virus type 2 isolates after 4 weeks of daily therapy. | pritelivir is a novel helicase-primase inhibitor in clinical development for treatment of herpes simplex virus type 2 (hsv-2) infections. in preclinical work, resistance-mediating mutations were identified in the hsv-2 genome at 3 loci in the ul5 gene and 1 locus in ul52. | 2016 | 27056950 |

| regulatory t cells are essential to promote proper cd4 t-cell priming upon mucosal infection. | regulatory t cells (tregs) limit autoimmunity and immunopathology using a variety of suppressive mechanisms, but their roles during pathogen-directed immune responses remain unclear. following herpes simplex virus-2 (hsv-2) infection, mice lacking tregs fail to control viral replication, pointing to a role for tregs in facilitating productive immune responses. using adoptive transfer of t-cell receptor transgenic cd4 t cells into treg-sufficient or treg-depleted mice prior to hsv-2 infection, we ... | 2016 | 27007674 |
| alphaherpesvirus subversion of stress-induced translational arrest. | in this article, we provide an overview of translational arrest in eukaryotic cells in response to stress and the tactics used specifically by alphaherpesviruses to overcome translational arrest. one consequence of translational arrest is the formation of cytoplasmic compartments called stress granules (sgs). many viruses target sgs for disruption and/or modification, including the alphaherpesvirus herpes simplex virus type 2 (hsv-2). recently, it was discovered that hsv-2 disrupts sg formation ... | 2016 | 26999187 |
| accumulation of a soluble form of human nectin-2 is required for exerting the resistance against herpes simplex virus type 2 infection in transfected cells. | cell entry of herpes simplex virus type 2 (hsv-2) requires the interaction of viral glycoprotein d (gd) with the receptor nectin-1 and herpesvirus entry mediator (hvem). in addition, it is known that nectin-2 is also functional as a receptor for hsv-2, although the binding to the gd is weak. to examine an antiviral potential of a soluble form of human nectin-2 (hnectin-2ig), transfected vero cells expressing the entire ectodomain of nectin-2 fused to the fc portion of human igg were established. ... | 2016 | 26982466 |
| seroprevalence and risk factors of herpes simplex virus-2 among pregnant women attending antenatal care at health facilities in wolaita zone, ethiopia. | herpes simplex virus type-2 is the common cause of genital ulcer disease worldwide. genital herpes infection is a major concern in pregnancy due to the risk of neonatal transmission. | 2016 | 26979484 |
| effect of condom use on per-act hsv-2 transmission risk in hiv-1, hsv-2-discordant couples. | the efficacy of condoms for protection against transmission of herpes simplex virus type 2 (hsv-2) has been examined in a variety of populations with different effect measures. often the efficacy has been assessed as change in hazard of transmission with consistent vs inconsistent use, independent of the number of acts. condom efficacy has not previously measured on a per-act basis. | 2016 | 26578538 |
| hexagonal-shaped chondroitin sulfate self-assemblies have exalted anti-hsv-2 activity. | the initial step in mucosal infection by the herpes simplex virus type 2 (hsv-2) requires its binding to certain glycosaminoglycans naturally present on host cell membranes. we took advantage of this interaction to design biomimetic supramolecular hexagonal-shaped nanoassemblies composed of chondroitin sulfate having exalted anti-hsv-2 activity in comparison with native chondroitin sulfate. nanoassemblies were formed by mixing hydrophobically-modified chondroitin sulfate with α-cyclodextrin in w ... | 2016 | 26572336 |
