| virion component of herpes simplex virus type 1 kos interferes with early shutoff of host protein synthesis induced by herpes simplex virus type 2 186. | herpes simplex virus (hsv) strains hsv type 1 (hsv-1) kos and hsv-2 186 are representative of delayed and early shutoff strains, respectively, with regard to their ability to inhibit protein synthesis in friend erythroleukemia cells. when these cells were simultaneously infected with hsv-1 kos and hsv-2 186, hsv-1 kos interfered with the rapid suppression of globin synthesis induced by hsv-2 186. the observed interference was competitive and not due to exclusion of hsv-2 by hsv-1 at the level of ... | 1985 | 2993660 |
| cytomegalovirus and herpes simplex virus ascending myelitis in a patient with acquired immune deficiency syndrome. | progressive ascending myelitis was the presenting feature of the acquired immune deficiency syndrome (aids) in a homosexual man who also had kaposi's sarcoma, pneumocystis pneumonia, and disseminated cytomegalovirus (cmv) infection. neuropathological studies showed profuse cytomegalic cells throughout the brain and spinal cord, but no inflammatory response. at postmortem examination, cmv and herpes simplex virus, type 2 (hsv-2), were recovered from multiple sites throughout the central nervous s ... | 1985 | 2994553 |
| immunoblotting and enzyme-linked immunosorbent assay analysis of serological responses in patients infected with herpes simplex virus types 1 and 2. | serological responses to soluble membrane and cytoplasmic antigens specified by herpes simplex type 1 (hsv1) and 2 (hsv2) were studied by immunoblotting and by enzyme-linked immunosorbent assay (elisa). in the immunoblotting test, polypeptides migrating like the hsv1-specified glycoprotein c showed type-specific reactivity but could not always be detected. the immunoblotting and elisa results were in agreement when antibody responses to hsv1- and hsv2-specified antigens were compared, and they a ... | 1985 | 2995271 |
| differences in humoral immunogenicity between herpes simplex virus types 1 and 2. | infection of nmri mice with increasing doses of six different strains of herpes simplex virus type 1 (hsv-1) induced increasing levels of neutralizing antibodies. in contrast, three strains of hsv-2, irrespective of the dose, induced only marginal antibody responses. only strain hg 52 (hsv-2) at high doses of infection stimulated antibody formation. the virus content of some organs in 6- to 8-week-old mice appeared to be lower after hsv-2 than after hsv-1 infection. application of immune-modulat ... | 1985 | 2995556 |
| inhibition of herpes simplex virus replication in vitro by human cytotoxic t cell clones and natural killer cell clones. | the abilities of human cytotoxic t cell (ctl) clones and natural killer (nk) cell clones to inhibit the replication of herpes simplex virus (hsv) in vitro were shown. the specificities of clones inhibiting hsv replication were the same as those of cytotoxicity in hsv type specificity and hla restriction, i.e. hsv type 1 (hsv-1) and hsv type 2 (hsv-2) common ctl clones inhibited the replication of both hsv-1 and hsv-2 in autologous cells, but not in allogeneic cells. hsv-1-specific ctl clones inh ... | 1985 | 2995557 |
| acute and latent herpes simplex virus neurological disease in mice immunized with purified virus-specific glycoproteins gb or gd. | groups of 5-week-old balb/c mice were immunized intraperitoneally with approximately 10 micrograms of purified alum-precipitated glycoprotein gb or gd of either herpes simplex virus type 1 (hsv-1) or type 2 (hsv-2) origin. control mice received injections of alum-precipitated 1% bovine serum albumin (bsa). following a second immunization 4 weeks later, seroconversion was confirmed by demonstrating the presence of glycoprotein-specific antibody by immune precipitation. all animals were challenged ... | 1985 | 2995573 |
| (+/-)-2-amino-3,4-dihydro-7-[2,3-dihydroxy-4-(hydroxymethyl)-1- cyclopentyl]-7h-pyrrolo[2,3-d]pyrimidin-4-ones: new carbocyclic analogues of 7-deazaguanosine with antiviral activity. | 5-allyl-2-amino-4,6-dihydroxypyrimidine (3) was chlorinated and ozonized to yield (2-amino-4,6-dichloro-pyrimidin-5-yl)acetaldehyde (5). acetalization of 5 with ethanol afforded a new pyrimidine intermediate 6 which can lead to 2-amino-3,4-dihydro-7-alkyl-7h-pyrrolo[2,3-d]pyrimidin-4-ones and therefore to carbocyclic analogues of 7-deazaguanosine. the 7-substituent was a cyclopentyl analogue of the arabinofuranosyl moiety in 10a, lyxofuranosyl moiety in 10b, and ribofuranosyl moiety in 10c. comp ... | 1985 | 2995667 |
| effect of dimethyl sulfoxide on interaction of human cytomegalovirus with host cell: conversion of a nonproductive state of cell to a productive state for virus replication. | the effect of dimethyl sulfoxide (dmso) on the interaction of human cytomegalovirus (hcmv) with host cell was studied. confluent state of a human rhabdomyosarcoma cell line (a204) showed a much lower susceptibility to hcmv infection when compared to that in subconfluent actively growing cell cultures. treatment of confluent cultures with dmso, however, converted many nonproductive cells in these cultures to a productive state for virus replication. infectious center assay revealed that approxima ... | 1985 | 2996216 |
| immunoperoxidase staining for the detection of herpes simplex virus antigen in cervicovaginal smears. | destained cervicovaginal smears from eight patients with herpes simplex virus (hsv) infections were stained by means of the peroxidase-antiperoxidase (pap) technique to demonstrate the presence of the hsv type 2 (hsv-2) antigen. positive results were obtained in six of the eight cases, with intense staining for the hsv-2-specific antigen throughout the cytoplasm and nuclei of cells having a ground-glass nuclear appearance as well as in multinucleated giant cells. virus isolation was successfully ... | 1985 | 2996270 |
| herpes simplex viral infection in human neonates: an immunohistochemical and electron microscopic study. | specimens obtained at autopsy from six neonates with herpes simplex virus (hsv) infections were examined microscopically, electron microscopically, and immunohistochemically. coagulative necrosis with inclusions was found in the livers and adrenal glands in all cases, as well as in various other organs, including the spleen, bone marrow, lungs, esophagus, tongue, and thymus, in some cases. distinct hemorrhagic diathesis was found in three cases. no characteristic clinical findings, such as skin ... | 1985 | 2997017 |
| the sources of thymidine nucleotides for virus dna synthesis in herpes simplex virus type 2-infected cells. | the thymidine nucleotide sources present during herpes simplex virus type 2 (hsv-2) infection were examined. it was concluded that the source of dttp in hsv-2-infected cells is not only derived from the ribonucleotide reductase-catalyzed de novo pathway, but also from host dna. when the de novo pathway was inhibited by the addition of hydroxyurea, an inhibitor of ribonucleotide reductase, the dttp levels were maintained by a compensatory increase in dttp derived from host dna. the utilization of ... | 1985 | 2997161 |
| humoral immune response to herpes simplex virus type 2 glycoproteins in patients receiving a glycoprotein subunit vaccine. | serial serum specimens from 22 herpes simplex virus (hsv)-seronegative recipients of an hsv type 2 (hsv-2) glycoprotein subunit vaccine were analyzed by radioimmunoprecipitation and polyacrylamide gel electrophoresis for the development of antibodies to hsv-2 gb, gd, and g80, a complex of gc and ge. volunteers received 50 (n = 12) or 100 micrograms (n = 10) of vaccine at days 0, 28, and 140; sera were drawn weekly for 8 weeks and again at days 140, 147, and 365. among seronegative volunteers, an ... | 1985 | 2997470 |
| evaluation of two rapid methods for the detection of herpes simplex virus antigen in patient specimens. | an indirect immunofluorescent antibody procedure (ifa) for the detection and typing of herpes simplex virus (hsv) and an enzyme-linked immunosorbent assay (elisa) procedure were compared with conventional viral culture. specimens for culture and elisa were inoculated into serum free viral transport medium (vtm) and, for ifa, onto slides provided in the kit. tissue cultures (mrc-5 and primary rabbit kidney) were inoculated and examined daily for cytopathogenic effect (cpe). the remaining vtm was ... | 1985 | 2998264 |
| topical butylated hydroxytoluene treatment of genital herpes simplex virus infections of guinea pigs. | the effect of topical treatment with butylated hydroxytoluene (bht) was evaluated in primary and recurrent genital herpes simplex virus type 2 (hsv-2) infection of guinea pigs. in the first experiment, treatment with placebo, 5%, 10%, or 15% bht was initiated 48 h after viral inoculation and continued 4 times daily for 15 days. during primary infection no differences in maximum lesion severity or titers of virus in lesions were observed, however, lesion duration was reduced in bht-treated animal ... | 1985 | 2998276 |
| delta-9-tetrahydrocannabinol decreases host resistance to herpes simplex virus type 2 vaginal infection in the b6c3f1 mouse. | the effect of delta-9-tetrahydrocannabinol (delta-9-thc) on host resistance to herpes simplex virus type 2 (hsv-2) vaginal infection in the b6c3f1 mouse was determined. animals were given delta-9-thc or vehicle on days -1 to 2, or cyclophosphamide on day -1 or on days -1 to 2. hsv-2 was introduced intravaginally on day 0. host resistance to virus infection was assessed by comparing frequency and severity of lesions, virus shedding and mortalities. replicate groups of animals were bled on days 5, ... | 1985 | 2999306 |
| synthetic glycoprotein d-related peptides protect mice against herpes simplex virus challenge. | glycoprotein d (gd) of herpes simplex virus (hsv) protects mice from a lethal challenge by either hsv type 1 (hsv-1; oral) or hsv-2 (genital). we evaluated whether synthetic peptides representing residues 1 through 23 of gd (mature protein) can be used as a potential synthetic herpesvirus vaccine. the immunogenicity of the peptides was demonstrated by the biological reactivity of antipeptide sera in immunoprecipitation and neutralization assays. all sera which immunoprecipitated gd had neutraliz ... | 1985 | 2999419 |
| effect of herpes simplex virus types 1 and 2 on surface expression of class i major histocompatibility complex antigens on infected cells. | cytotoxic t lymphocytes (ctl) generated in c57bl/6 (h-2b) mice in response to infection with the serologically distinct herpes simplex virus type 1 (hsv-1) or type 2 (hsv-2) were cross-reactive against target cells infected with either serotype. however, hsv-2-infected cells were shown to be much less susceptible to ctl-mediated lysis, and analysis through the use of hsv-1 x hsv-2 intertypic recombinants mapped the reduced susceptibility to a region contained within 0.82 to 1.00 map units of the ... | 1985 | 2999432 |
| a modular system for the assay of transcription regulatory signals: the sequence taatgarat is required for herpes simplex virus immediate early gene activation. | a modular system for assaying the activity of transcriptional regulatory signals based on herpes simplex virus (hsv) promoter and terminator sequences linked to the bacterial chloramphenicol acetyltransferase (cat) gene has been used to study activation of hsv immediate early (ie) gene expression. insertion of the sv40 72 base pair (bp) repeat increased mrna levels by 15-fold thus demonstrating the ability of the hsv ie promoter to respond to a heterologous enhancer. a fragment containing part o ... | 1985 | 2999706 |
| expression of the herpes simplex virus type-2 major dna-binding protein (icp8) gene in cos-1 cells. | by the use of an sv40 origin of replication plasmid vector and the cos-1 cell system, expression of the gene encoding the herpes simplex virus type-2 (hsv-2) major dna binding protein (icp8) has been achieved. the hsv-2 4.5 kb bglii 0 dna fragment containing the icp8 coding region was inserted into the plasmid vector psvod containing the sv40 origin of replication. transfection of cos-1 cells by the resultant recombinant plasmid (psvod20), and subsequent multiplication of this plasmid, led to th ... | 1985 | 3000103 |
| synergistic effect of human leukocyte interferon and nonoxynol 9 against herpes simplex virus type 2. | the nonionic surfactant nonoxynol 9 (np9), in combination with human alpha interferon, synergistically reduced the titer of herpes simplex virus type 2 (hsv-2) in vitro. the degree of synergy was highest at an interferon concentration of 10(3) iu/ml and an np9 dilution of 1:1,500. we postulate that np9 inactivates extracellular hsv-2, whereas interferon inhibits hsv-2 replication at the intracellular level. | 1985 | 3000288 |
| antiviral activity of 5-ethyl-2'-deoxyuridine against herpes simplex viruses in cell culture, mice, and guinea pigs. | the susceptibility of 3 laboratory strains and 24 clinical isolates of herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) to 5-ethyl-2'-deoxyuridine was determined in plaque reduction assays in vero cells. the median effective doses were 8.6 and 7.8 microm, respectively. the drug was less potent than acyclovir and other related antiviral drugs, but it had a high therapeutic index against both hsv-1 and hsv-2. drug-resistant viruses were readily produced in cell culture. these variants were c ... | 1985 | 3000291 |
| construction of rat cell lines that contain potential morphologically transforming regions of the herpes simplex virus type 2 genome. | hybrid recombinant plasmids were constructed; they were composed of the herpes simplex virus type 2 (hsv2) thymidine kinase (tk) gene and dna sequences of hsv2 that have been reported to induce morphological and/or oncogenic transformation of rodent cells in culture. several plasmids were made in two versions, with or without the simian virus 40 enhancer sequences. these plasmids were employed to transfect contact-inhibited rat-2 tk- cells. it was demonstrated that cell lines with stably integra ... | 1985 | 3000980 |
| recurrent genital herpes simplex virus infection in guinea pigs. | after recovery from initial genital herpes simplex virus (hsv) infections, female guinea pigs developed spontaneous recurrent infections characterized by discrete erythematous or vesicular herpetic lesions on the external genital skin. hsv type 2 (hsv2) caused significantly more recurrent infections in guinea pigs than did hsv type 1 (hsv1). hsv2-infected animals demonstrated a significant decline in frequency of recurrences over time. the viral nature of the recurrent lesions was confirmed by r ... | 1985 | 3000982 |
| the cervical tumor-associated antigen (icp-10/ag-4) is encoded by the transforming region of the genome of herpes simplex virus type 2. | bglii fragment c mapping between 0.416 and 0.580 map units (mu) on the herpes simplex virus type 2 (hsv-2) genome was used for in vitro translation to identify proteins encoded on this fragment. rna homologous to the bglii c fragment directs the synthesis of three proteins with approximate molecular weights of 144,000, 52,000 and 27,000. the 27,000 dalton protein is encoded by sequences within the ecori/hindiii ae fragment (0.419-0.525 mu) that overlap the immortalizing sequences within bglii c. ... | 1985 | 3001010 |
| typing of herpes simplex virus isolates with monoclonal antibodies and by nucleic acid spot hybridization. | fifty-one clinical isolates of herpes simplex virus (hsv) were typed by an enzyme immunoassay (eia) using mouse monoclonal antibodies, by dna spot hybridization, and by restriction enzyme analysis using restriction endonuclease eco ri. extracts of vero cells infected with the isolates were used for coating microtitre plates or denatured and spotted onto nitrocellulose filters. viral antigens passively adsorbed to microtitre plates were detected by an indirect eia using mouse monoclonal antibodie ... | 1985 | 3001118 |
| detection of herpes simplex virus type 2-specific antibody with glycoprotein g. | a recently described herpes simplex virus (hsv) type 2 (hsv-2)-specific glycoprotein (gg-2) was purified on an immunoaffinity column prepared with monoclonal antibody. this purified antigen was used in an immunodot enzymatic assay on nitrocellulose paper for the detection of hsv-2 antibodies in human serum. the test was very sensitive in that hsv-2 antibodies were detected in the convalescent sera of 132 of 134 patients with recurrent genital infections in which hsv-2 had been isolated earlier. ... | 1985 | 3001136 |
| detection of herpesvirus cervicovaginitis by a sequential papanicolaou--immunoperoxidase technique. | herpes simplex virus (hsv) infection constitutes an immediate threat to the neonate of pregnant women who deliver vaginally, and thus requires a rapid, specific means of diagnosis that is easily applicable to cervicovaginal smears. we applied the peroxidase-antiperoxidase technique to variously fixed, previously stained papanicolaou smears from 60 women with hsv and 18 negative controls using an hsv-2 antibody and either diaminobenzidine (dab) or aminoethylcarbazol (aec) as the chromogen and may ... | 1985 | 2424682 |
| anti-herpes simplex virus and cytostatic activity of some new 5-substituted 1-(4-hydroxybutyl)-and 1-(2-hydroxyethoxymethyl) uracil nucleoside analogues. | two series of 5-substituted acyclic uracil nucleoside analogues (5-x-acyclo-u) were evaluated for their inhibitory effects against three herpes simplex virus type 1 (hsv-1) strains and one type 2 (hsv-2) strain in a plaque inhibition assay on human embryonic lung fibroblast (helf) cell cultures as well as for their ability to inhibit the proliferation of baby hamster kidney cells in suspension (bhk-s) culture. acyclovir [9-(2-hydroxyethoxymethyl)guanine; acv] and (s)-9-(2,3-dihydroxypropyl)adeni ... | 1985 | 2864819 |
| herpes simplex virus hepatitis in mice: effects of treatment with trisodium phosphonoformate. | clinical isolates of herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) induced focal necrotic hepatitis in icr/schö mice. the extent of the hepatitis could be considerably reduced by trisodium phosphonoformate (pfa) administered for 3 days in a daily dose of 400-600 mg/kg. the hsv hepatitis in mice could serve as a suitable model for testing antiherpetic drugs. | 1985 | 2869661 |
| multistep transformation by defined fragments of herpes simplex virus type 2 dna: oncogenic region and its gene product. | diploid syrian hamster embryo cells transfected with bgl ii c fragment of herpes simplex virus type 2 dna acquired a neoplastic phenotype. cultures transfected with its left-hand 64% subclone ecori/hindiii fragment ae (0.419-0.525 map unit) grew into established but nontumorigenic lines. transfection of ecori/hindiii ae-immortalized cells with a 4.4-kilobase sac i/bamhi subfragment within bamhi e (0.554-0.584 map unit; overlaps the right-hand 16% of bgl ii c) converted them to tumorigenicity. th ... | 1985 | 3001705 |
| risk of recurrence after treatment of first-episode genital herpes with intravenous acyclovir. | to determine whether intravenous acyclovir treatment for a first episode of genital herpes could prevent or reduce subsequent recurrences, we combined and analyzed the results of two independently conducted, randomized, double-blind, placebo-controlled studies. sixty-one patients were enrolled in the two trials; 30 received the drug, and 31 received placebo. at entry the demographic, epidemiologic, and clinical features of acyclovir- and placebo-treated patients from the two centers showed no si ... | 1985 | 3001952 |
| herpes simplex virus antigen detection in human acute encephalitis: an immunohistochemical study using avidin-biotin-peroxidase complex method. | autopsy specimens from six patients with clinically diagnosed herpes simplex virus (hsv) encephalitis were studied. since immunocytochemistry has been reported to be a more reliable and successful method to identify hsv as the etiologic agent, antitype 1 hsv (hsv1) and antitype 2 hsv (hsv2) and the avidin-biotin-peroxidase complex (abc) method were applied to brain paraffin sections. positive immunostaining was observed in front-orbital, mediobasal temporal lobes, cingulate gyrus, and insula. th ... | 1985 | 3002087 |
| [inhibition of virus multiplication by immunoactive peptides]. | in the present study we show that peritoneal macrophages obtained from the mice treated with the immunoactive peptides inhibit the multiplication of herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2), but not that of vesicular stomatitis virus (vsv), and that the intraperitoneal administration of the peptides suppresses the infection with hsv-1 in mice. | 1985 | 3002570 |
| detection of herpes simplex virus type-2 antigen(s) in biopsies from carcinoma of the uterine cervix. | indirect immunofluorescence technique was employed to detect herpes simplex virus type-2 (hsv-2) antigens in tumor biopsies from 215 patients with carcinoma of the uterine cervix. a total of 169 samples (79%) revealed brilliant nuclear fluorescence. inflammatory cells infiltrating the tumor mass were positive to 60 of the 215 patients (28%). samples showed no significant variation in the degree of fluorescence or proportion of cells binding hsv antibody with advancement in the clinical stage of ... | 1985 | 2431113 |
| the effect of food dye and other environmental substances on the host defense reaction in mice in relation to virus infection. | environmental substances were examined for their effect on interferon induction and delayed type hypersensitivity (dth) responses in mice. amaranth, safrole, phenacetin and nicotine suppressed the dth response, and suppressed the serum interferon titers induced by virus infection. however, they did not affect the interferon titers which were induced by tilorone, a chemical inducer. the peak of interferon titer was 12 hours after infection with herpes simplex virus type 2 (hsv-2). therefore, amar ... | 1986 | 2432279 |
| enhancement of host resistance against virus infections by mtp-pe, a synthetic lipophilic muramyl peptide--i. increased survival in mice and guinea pigs after single drug administration prior to infection, and the effect of mtp-pe on interferon levels in sera and lungs. | muramyl tripeptide-phosphatidylethanolamine (mtp-pe, cgp 19835) displays prophylactic antiviral activity in mice infected with influenza viruses a and b, parainfluenza 1 virus or herpes simplex type 1 viruses (hsv/1) and in guinea pigs infected with herpes simplex type 2 viruses (hsv/2). mtp-pe is effective when given in a single intranasal dose as early as 1-4 weeks before infection. in the case of hsv/2 infections, prophylactic effectiveness can be demonstrated after a single topical applicati ... | 1986 | 2433236 |
| mothers of children with down syndrome have higher herpes simplex virus type 2 (hsv-2) antibody levels. | the antibody response to herpes simplex virus (hsv) was studied in 53 mothers of children with down syndrome (ds) and compared with that in 154 controls, using sera sampled during pregnancy or at delivery. conventional analysis of hsv complement fixing antibodies showed the same frequency of positivity for the two groups (70%). when the levels of igg antibodies to an hsv-1 and an hsv-2 antigen preparation were determined by an enzyme-linked immunosorbent assay (elisa) technique, it was found tha ... | 1986 | 3002957 |
| infection of the adrenal gland as a route to the central nervous system after viraemia with herpes simplex virus in the mouse. | intravenous inoculation of 4-week-old female nih (inbred) mice with herpes simplex virus type 1 (hsv-1) strain p2c6 (defective in thymidine kinase) produced bilateral hind limb paralysis in nearly all animals by the 5th day after inoculation; very few mice died. in male mice the incidence and severity of paralysis was considerably lower than in females. the parental strain, cl(101), produced similar paralysis but all mice died by day 7. observations on paralysis and death after intravenous inocu ... | 1986 | 3003239 |
| an in vitro latency system for herpes simplex virus type 2. | an in vitro latency system for herpes simplex virus type 2 (hsv-2) in cultured cells has been developed. virus replication was suppressed by infection of human foetal lung cells at the supraoptimal temperature of 42 degrees c, and, following transfer of such cell cultures to the normal growth temperature of 37 degrees c, infectious virus was generally undetectable for at least 6 days. hsv-2 was reactivated by intertypic superinfection at 38.5 degrees c with temperature-sensitive mutants of hsv-1 ... | 1986 | 3003243 |
| age-specific prevalence of antibodies to pyrimidine kinase enzymes of herpes simplex virus types 1 and 2, and of varicella zoster virus. | the age-specific prevalence of antibodies to pyrimidine kinase enzymes of herpes simplex virus types 1 (hsv-1) and 2 (hsv-2) and of varicella zoster virus (vzv) was measured in serum specimens from 360 persons. specific inhibition of viral enzyme activity by the serum was used as an indication of the presence of antibodies to the enzyme. for hsv-1 and hsv-2 together the overall prevalence of positive sera increased with age and reached about 50% in the older age groups, the major part of the pos ... | 1986 | 3003247 |
| hexavalent capsomers of herpes simplex virus type 2: symmetry, shape, dimensions, and oligomeric status. | the structures of the hexavalent capsomers of herpes simplex virus type 2 were analyzed by negative staining electron microscopy of capsomer patches derived from partially disrupted nucleocapsids. optimally computer-averaged images were formed for each of the three classes of capsomer distinguished by their respective positions on the surface of the icosahedral capsid with a triangulation number of 16; in projection, each capsomer exhibited unequivocal sixfold symmetry. according to corresponden ... | 1986 | 3003389 |
| hsv infected raji-cells specify hsv specific immediate early and/or early dna-binding proteins. | herpes simplex virus specified dna-binding proteins were purified from virus infected vero and raji cells. the expression of the proteins differed depending on the type of the host cell. polypeptides corresponding to hsv-1 specific icp 8 and hsv-2 specific icsp 11/12 were the major products of hsv-infected vero cells. in raji cells polypeptides with a corresponding molecular weight, together with a cellular protein having almost similar mobility on sds gels could be detected. using immuno-blotti ... | 1986 | 3002298 |
| transcriptional induction of cellular gene expression during lytic infection with herpes simplex virus. | herpes simplex virus type 2 causes a severe repression of host cell biosynthesis at a number of levels. we show that despite this, non-viral cdna clones derived from cellular rna species which accumulate to high levels after infection can be isolated using differential screening techniques. by using nuclear run-off assays, we have shown that this rna accumulation is mediated by transcriptional induction of the corresponding cellular genes. | 1986 | 2883998 |
| induction of recurrent genital herpes simplex virus type 2 infection by ultraviolet light. | 1986 | 2870285 | |
| studies on interactions of dtk-hsv mutants with neurons in vitro. | thymidine kinase negative (dtk-) mutants of herpes simplex virus type 1 (hsv-1) multiplied well in rat brain glioma cells. a proportion (less than 1%) of glioma cells survived the infection with hsv and were designated "survivor" glioma cells. survivor cells of dtk- mutant virus infection ceased to produce infectious virus after two passages and were highly resistant to both hsv-1 and hsv-2 but not to vesicular stomatitis virus (vsv). flow cytometric studies indicated morphological differences b ... | 1986 | 2871727 |
| early intrathecal production of specific igm and igg antibodies and alpha-interferon in herpes simplex virus encephalitis. | a complex approach was used in order to establish non-invasively the aetiology in three cases of encephalitis presumptively caused by herpes simplex virus (hsv). as indicative of brain hsv infection was considered the lowered serum to cerebrospinal fluid specific antibody ratio, which also assessed the humoral immune response within the cns. for this purpose, during ongoing brain tissue infection, the early intrathecal (ith) production of igg and igm antibodies was analysed by a differential enz ... | 1986 | 2873733 |
| induction of chromosomal aberrations in human cells by a temperature-sensitive mutant of herpes simplex virus type 2 and its revertants. | the induction of chromosomal aberrations by a temperature-sensitive (ts) mutant of herpes simplex virus type 2 (hsv-2) strain hg52 (ts 13), its revertants 4-8 and 5-8 and by etalon strains hsv-1 17 syn+ and hsv-2 hg52 was studied in human fibroblast and lymphocyte cultures. the effect on chromosomes of the revertants was tested at permissive (31 degrees c) and non-permissive (38 degrees c) temperatures. at 38 degrees c the revertants could not induce dnase activity. the present results contribut ... | 1986 | 2874732 |
| vaccine potential of a live avirulent herpes simplex virus. | we previously described a herpes simplex intertypic recombinant that is completely and specifically non-neurovirulent following intracranial inoculation. in this report the vaccine potential of this mutant (re6) is analyzed. it is shown that re6 replicates to wild type levels at the peripheral site of inoculation (the mouse footpad) but, unlike its virulent parental strains, does not replicate to detectable levels in lumbosacral ganglia. a single vaccination with re6 is sufficient to completely ... | 1986 | 2854601 |
| structural features of ribonucleotide reductase. | herpes simplex virus type 1 (hsv-1) encodes a ribonucleotide reductase which comprises two polypeptides with sizes of 136,000 (rr1) and 38,000 mol. wt. (rr2). we have determined the entire dna sequence specifying hsv-1 rr1 and have identified two adjacent open reading frames in varicella-zoster virus (vzv) which have homology to hsv rr1 and rr2; the predicted sizes for the vzv rr1 and rr2 polypeptides are 87,000 and 35,000 mol. wt. respectively. amino acid comparisons with rr1 and rr2 polypeptid ... | 1986 | 2835765 |
| acyclovir treatment of disseminated herpes simplex virus type 2 infection in weanling mice: alteration of mortality and pathogenesis. | intranasal inoculation of weanling mice with herpes simplex virus type 2 (hsv-2) provides an experimental infection that closely resembles disseminated and central nervous system hsv infections of human neonates. intraperitoneal treatment with acyclovir (acv) successfully reduced mortality even when therapy was begun as late as 2 days and oral therapy as late as 4 days after viral challenge. treatment with acv beginning on day 1 completely inhibited hsv-2 replication in lung, spleen, kidney, olf ... | 1986 | 2427021 |
