evidence for deficiencies in intracerebral cytokine production, adhesion molecule induction, and t cell recruitment in herpes simplex virus type-2 infected mice. | we examined the intracerebral t cell response in mice infected with neurovirulent hsv-2 strains and an avirulent hsv-1. in hsv-2-infected brains, (i) il-1beta, tnf-alpha and ifn-gamma mrna expression was low, (ii) icam-1 and vcam-1 were not induced, (iii) few cd4+ or cd8+ cells were detected. by contrast, in hsv-1-infected brains, (i) cytokine mrna expression was high, (ii) adhesion molecules were strongly expressed, (iii) many t cells were detected. we suggest that deficient t cell extravasatio ... | 1998 | 9521606 |
evidence that deficient ifn-gamma production is a biological basis of herpes simplex virus type-2 neurovirulence. | although immune response control of herpes simplex virus (hsv) has been well demonstrated, numerous hsv-2 strains are neurovirulent in immunocompetent mice. using an rnase protection assay and an elisa, we found that hsv-2-infected mice exhibited a deficient ifn-gamma response, an inability to clear virus, and eventual death. an hsv-based amplicon vector expressing mouse ifn-gamma was constructed and packaged into hsv-1-helper virus (hsv(pifn-gamma)). in mice treated with hsv(pifn-gamma), (i) th ... | 1998 | 9521607 |
neonatal herpes simplex virus infections. | neonatal herpes simplex virus (hsv) infection is one of the life-threatening infections of newborns. it affects approximately 1,500 to 2,200 infants per year in the united states. changes in the presentation of neonatal hsv infection over the past two decades include an increase in the frequency of skin, eye, and mouth (sem) disease with a relatively unchanged rate of central nervous system (cns) disease, but a relative decline in disseminated infection. although the mortality of neonatal hsv in ... | 1998 | 9523400 |
perspectives on switching oral acyclovir from prescription to over-the-counter status: report of a consensus panel. | the proposed switching of oral acyclovir from prescription to over-the-counter (otc) status for the 5-day episodic treatment of genital herpes was considered by a consensus panel. it was concluded that self-diagnosis/misdiagnosis, misuse, and adverse drug effects were potential problems with the otc use of acyclovir. while acyclovir reduces asymptomatic shedding of herpes simplex virus type 2, the reduction in transmission of virus potentially resulting from increased acyclovir use was felt to b ... | 1998 | 9524840 |
mucosal immunity to herpes simplex virus type 2 infection in the mouse vagina is impaired by in vivo depletion of t lymphocytes. | intravaginal (ivag) inoculation of wild-type herpes simplex virus type 2 (hsv-2) in mice causes epithelial infection followed by lethal neurological illness, while ivag inoculation of attenuated hsv-2 causes epithelial infection followed by development of protective immunity against subsequent ivag challenge with wild-type virus. the role of t cells in this immunity was studied by in vivo depletion of these cells with monoclonal antibodies. three groups of mice were used for each experiment: non ... | 1998 | 9525585 |
the quantity of latent viral dna correlates with the relative rates at which herpes simplex virus types 1 and 2 cause recurrent genital herpes outbreaks. | herpes simplex virus types 1 and 2 (hsv-1 and hsv-2) have evolved specific anatomic tropisms and site-dependent rates of reactivation. to determine whether reactivation rates depend on distinct abilities of hsv-1 and -2 to establish latency and to express latency-associated transcripts (lats), virulent strains of each virus were studied in the guinea pig genital model. following infection with equivalent titers of virus, the quantities of latent hsv-2 genomes and lats were higher in lumbosacral ... | 1998 | 9525595 |
clearance of hsv-2 from recurrent genital lesions correlates with infiltration of hsv-specific cytotoxic t lymphocytes. | the mechanisms involved in host clearance of symptomatic mucocutaneous herpes simplex virus (hsv) infection are unclear. we studied the functional properties of bulk cultures of skin-infiltrating lymphocytes from normal skin and serial biopsies of recurrent genital hsv-2 lesions, and compared hsv-specific and nk responses with viral clearance. hsv-specific cd4+ or cd8+ t cells were rarely detected in lymphocytes cultured from normal skin. the total lymphocyte count and hsv-specific and nk-like e ... | 1998 | 9525993 |
the novel immunosuppressive agent mycophenolate mofetil markedly potentiates the antiherpesvirus activities of acyclovir, ganciclovir, and penciclovir in vitro and in vivo. | the immunosuppressive agent mycophenolate mofetil (mmf) has been approved for use in kidney transplant recipients and may thus be used concomitantly for the treatment of intercurrent herpesvirus infections with drugs such as acyclovir (acv), ganciclovir (gcv), and penciclovir (pcv). we found that mmf and its parent compound mycophenolic acid (at concentrations that are attainable in plasma) strongly potentiate the antiherpesvirus (herpes simplex virus [hsv] type 1 [hsv-1], hsv-2, thymidine kinas ... | 1998 | 9527762 |
influence of mucosal and parenteral immunization with a replication-defective mutant of hsv-2 on immune responses and protection from genital challenge. | herpes simplex virus (hsv) most frequently initiates infection at a mucosal surface; thus mucosal immune responses are likely to be important in defense against hsv infection. we have examined the effects of eliciting mucosal as well as systemic immune responses on protection against genital challenge infection with virulent hsv-2 in mice immunized with a replication-defective mutant of hsv-2. in addition, we have examined the types of immune responses elicited by immunization by the different r ... | 1998 | 9527927 |
the comparative biology of latent herpes simplex virus type 1 and type 2 infections: latency-associated transcript promoter activity and expression in vitro and in infected mice. | hsv-1 and hsv-2 express abundant latency-associated transcripts (lats) without which these viruses reactivate in animals inefficiently. to further characterize the importance of lats to the comparative biology of latent hsv-1 and -2 infections, we assessed the relative activities of the viral lat promoters in vitro using transient transfection assays, and the accumulation of lats in vivo using a mouse ocular infection model. in vitro, the hsv-2 lat promoter proved to be six to tenfold more poten ... | 1998 | 9531009 |
increase in vdelta1+ gammadelta t cells in the peripheral blood and bone marrow as a selective feature of hiv-1 but not other virus infections. | dysregulation of t-cell receptor (tcr) alphabeta bearing lymphocytes and an increase in vdelta1+ gammadelta t cells are typical features of hiv-1 infection. however, the role of gammadelta t cells remains unclear. therefore, peripheral blood mononuclear cells (pbmc) of 103 hiv-1-infected patients were investigated with respect to expression of vdelta1. these results were compared to the vdelta1 expression of bone marrow mononuclear cells (bmmc). in contrast to healthy controls, vdelta1+ cells do ... | 1998 | 9531341 |
[genital herpes with special emphasis on perinatal herpes simplex virus infection]. | the incidence of genital herpes is increasing worldwide and at present herpes simplex virus type 2 is the most common cause of genital ulceration all over the world. classification: the international herpes management forum (ihmf) was established in 1993, suggesting a new classification of genital herpes: primary genital herpes, non-primary genital herpes, recurrent genital herpes, first episode genital herpes, atypical genital herpes and asymptomatic hsv (herpes simplex virus) infection. | 1998 | 9531774 |

evidence of latency and reactivation of both herpes simplex virus (hsv)-1 and hsv-2 in the genital region. | while superinfection with different herpes simplex virus (hsv) types has been demonstrated in animals, the ability of the two hsv types to colonize and reactivate in the same anatomic region in humans has not been well demonstrated. in 6 patients, both hsv-1 and hsv-2 was recovered from genital lesions. in 4 of them, who initially acquired genital hsv-1 infection, subsequent hsv-2 infection presented as a prolonged episode of genital lesions and a marked increase in the frequency of genital recu ... | 1998 | 9534984 |
antibodies to varicella zoster virus in the cerebrospinal fluid of neonates with seizures. | four neonates with convulsions had igg antibodies in their cerebrospinal fluid (csf) to varicella zoster virus (vzv). these antibodies were found in the sera of two of these patients after the age of 6 months. antibodies to 16 different microbes were studied from the serum and csf of 201 neonates with neurological problems. the presence of dna specific to hsv-1, hsv-2, and vzv in the csf was also investigated using the polymerase chain reaction (pcr). antibodies to vzv were detected in the csf o ... | 1998 | 9536843 |
genital herpes: epidemiology and pathophysiology. update and new perspectives. | genital herpes simplex virus (hsv) is a sexually transmitted disease (std) which affects millions of people worldwide and is mainly due to hsv type 2. seroprevalence rates as high as 60-90% have been reported in developing countries. in developed countries, 20% of the general population is hsv2 seropositive. recent epidemiological surveys employing type-specific antibody assays show that the prevalence of hsv-2 infections is rising at an alarming rate. also, the epidemiology is changing with an ... | 1997 | 9538399 |
a study of the viral etiology of histiocytic necrotizing lymphadenitis (kikuchi-fujimoto disease). | histiocytic necrotizing lymphadenitis (hnl) or kikuchi's disease is a distinctive, self-limited disorder characterized by necrotizing cervical lymphadenopathy in young individuals. hnl is more prevalent among asians and is a relatively common disorder among koreans. a preceding fever, lymphopenia, and occasional skin rashes suggest a viral etiology and there have been sporadic reports of viral association. however, so far, no infectious agent has been proven to be etiologically related. in the p ... | 1998 | 9539315 |
metal complexes of bovine lactoferrin inhibit in vitro replication of herpes simplex virus type 1 and 2. | the inhibitory effect of bovine lactoferrin (blf) saturated with ferric, manganese or zinc ions, on the infection of vero cells by human herpes simplex virus type 1 (hsv1) and 2 (hsv2) was investigated. viral infectivity determined by intracellular antigen synthesis and plaque formation was efficiently inhibited by metal saturated lactoferrins in a dose-dependent manner. effective blf concentrations which reduced the infection by 50% ranged from 5.2 to 31 micrograms ml-1 and were far below the c ... | 1998 | 9542061 |
