| "in vivo" and "in vitro" effects of a bacterial extract on herpes simplex virus. | the present studies were designed to evaluate the effects of substance or substances extracted from escherichia coli on herpes simplex virus. the "in vivo" assays show that bacterial extract introduced i.p. in mice simultaneously with hsv2 brought about 100% of survival, but the inoculation of crude extract after virus challenge brought about complete mortality of mice. "in vitro" assays show that the crude extract reduced significantly the numbers of pfu; better results were obtained when the c ... | 1980 | 6255968 |
| double infection of balb/c mice with rauscher murine leukemia and herpes simplex virus type 2. | when balb/c mice were first infected with rauscher murine leukemia virus (mulv-r) and then superinfected with herpes simplex virus type 2 (hsv-2) the inhibition of the evolution of splenomegaly was observed. the effect did not depend on the route of hsv-2 administration. experiments in which potent anti-interferon serum was administered to double infected mice suggested that the antagonism between mulv-r and hsv-2 was not mediated by endogenous interferon, hsv-2 was found to replicate in the lps ... | 1980 | 6255890 |
| an evaluation of herpes simplex virus antigenic markers in the study of established and developing cervical neoplasia. | previous reports from our laboratory have shown that antiserum to "pure" ag-e, a type-common hsv antigen, specifically stains atypical cervical cells in indirect immunofluorescence. these observations have been confirmed and extended. antisera were prepared against the two protein components of pure ag-e, designated icp 12 (m. w. = 140,000) and icp 14 (m. w. = 130,000), and were purified to radiochemical homogeneity by sds-acrylamide gel electrophoresis. the antisera reacted as well as antiserum ... | 1980 | 6255843 |
| comparative structural analysis of glycoprotein gd of herpes simplex virus types 1 and 2. | we studied the synthesis and processing of the type-common glycoprotein gd in herpes simplex virus type 2 (hsv-2) and compared it structurally to glycoprotein gd of herpes simplex virus type 1 (hsv-1). we demonstrated that in hsv-2, gd undergoes posttranslational processing from a lower-molecular-weight precursor (pgd51) to a higher-molecular-weight product (gd56). tryptic peptide analysis by cation-exchange chromatography indicated that this processing step altered neither the methionine nor th ... | 1980 | 6255183 |
| quantification of plasminogen activator activity associated with herpesvirus-transformed cells. | herpesvirus-transformed cell lines were examined for plasminogen activator (pa) activity using a quantitative assay. previous results of cold fibrin overlay assays indicated that herpesvirus-transformed hamster cell lines produce fibrinolytic activity. quantification of this activity involved the use of an 125i-fibrin lysis assay in which medium previously incubated with transformed or normal cells was tested for its ability to lyse 125i-fibrin polymers. this assay indicated an enhanced producti ... | 1980 | 6255081 |
| the effect of delta-9-tetrahydrocannabinol on herpes simplex virus replication. | both herpes simplex virus type 1 (hsv-1) and herpes simplex virus type 2 (hsv-2) failed, in an identical fashion to replicate and produce extensive c.p.e. in human cell monolayer cultures which were exposed (8 h before infection, at infection, or 8 h p.i.) to various concentrations of delta-9-tetrahydrocannabinol. similar results were obtained with a plaque assay utilizing confluent monkey cells. possible mechanisms for this antiviral activity are discussed. | 1980 | 6255077 |

| immunity to herpes simplex virus type 2: cell-mediated immunity in latently infected guinea pigs. | cell-mediated (cmi) and humoral immunity to herpes simplex virus type 2 (hsv-2) were evaluated in infected strain 13/n guinea pigs with (45%) and without a history of recurrent herpetic disease. virus was isolated by cocultivation from active herpetic lesions (9 of 10) as well as from the footpads (17 of 38), sacral ganglia (7 of 21), and sciatic nerves (1 of 21) of asymptomatic animals. viral isolates grew in cells of human origin and were neutralized by hyperimmune anti hsv-2 sera. humoral imm ... | 1980 | 6254886 |
| pathogenicity of wild-type and temperature-sensitive mutants of herpes simplex virus type 2 in guinea pigs. | the pathogenicity of herpes simplex virus type 2 strain 186, the wild-type (wt) strain, and four temperature-sensitive (ts) mutants was studied after genital inoculation of female guinea pigs. infection with the wt virus was generally severe, with extensive skin lesions in 89% and mortality in 37% of inoculated animals. guinea pigs inoculated with ts mutants manifest remarkably mild disease, with lesions occurring in only 16% of the guinea pits and a mortality rate of 7%. wt virus was recovered ... | 1980 | 6254877 |
| reaction patterns of herpes simplex virus type 1 and type 2 proteins with sera of patients with uterine cervical carcinoma and matched controls. | serum from 105 individuals with diagnosed uterine cervical cancer and 231 matched controls were examined for their ability to react with a large number of herpes simplex virus type 1 or type 2 (hsv-1, hsv-2) proteins. radiolabeled hsv-1 or hsv-2 proteins were mixed with test serum and immune complexes were isolated with staphylococcal protein a. viral proteins in the immune complexes were resolved by polyacrylamide gel electrophoresis and visualized by fluorography. when the frequency of precipi ... | 1980 | 6254649 |
| comparison of indirect hemagglutination and 51chromium release tests for detection of herpes simplex virus type 1 and 2 antibodies in patients with recurrent herpes infections. | indirect hemagglutination and 51cr release tests (ihat and 51-crt respectively) were compared in patients with recurrent herpes simplex virus (hsv) infections from whom hsv-1 or hsv-2 was isolated. both tests were equally sensitive and specific in detecting hsv antibodies. however, ihat was more specific in detecting homologous hsv antibody response in patients with recurrent hsv-2 infections. past infections with hsv-1 in the patients with dual infections were detected by determining hsv-type s ... | 1980 | 6254476 |
| responses of mouse spleen morphology to the growth of subcutaneously injected virally transformed cells. | the changes in the fractional volume of six structural components in the spleens of balb/c mice injected with herpes simplex virus type 2-transformed cells (h238 tumor cells) were quantitated during progressive tumor growth. spleen stereology was performed at three time intervals during the early stages of tumor development. the results revealed that the volume of the compact myeloid tissue and reaction center of lymphoid nodules increased about four- to five-fold from 10 to 33 days after h238 t ... | 1980 | 6254396 |
| temporal regulation of herpes simplex virus type 2 transcription and characterization of virus immediate early mrna's. | nuclear and cytoplasmic virus rnas, synthesized in cells infected with herpes simplex virus type 2 at early and late times post-infection, and in the continuous presence of the protein synthesis inhibitor cycloheximide (immediate early), have been analyzed by blot hybridization to virus dna fragments generated by bam hi and eco ri restriction endonucleases. polyadenylated immediate early mrnas were separated on denaturing gels containing ch3hgoh giving three virus-specific mrna bands of estimate ... | 1980 | 6253886 |
| herpes simplex virus phosphoproteins. ii. characterization of the virion protein kinase and of the polypeptides phosphorylated in the virion. | the protein kinase associated with purified herpes simplex virus 1 and 2 virions partitioned with the capsid-tegument structures and was not solubilized by non-ionic detergents and low, non-inhibitory concentrations of urea. the enzyme required mg2+ or mn2+ and utilized atp or gtp. the activity was enhanced by non-ionic detergents and by na+ even in the presence of high concentrations of of mg2+, but not by cyclic nucleotides. the enzyme associated with capsid-tegument structures phosphorylated ... | 1980 | 6252339 |
| experimental infection and the state of viral latency of adult tupaia with herpes simplex virus type 1 and 2 and infection of juvenile tupaia with temperature-sensitive mutants of hsv type 2. | the susceptibility of adult tupaia belangeri to infection with herpes simplex virus (hvs) was investigated. adult animals were inoculated intraperitoneally with hsv type 1 or 2. with the exception of hsv-2, strain hg-52, 10(5)--10(6) pfu of all hsv strains caused lethal infection irrespective of the age of the animals. infections hsv was recovered from the spinal cord of those animals which had survived infection with a low dose of virus. the dna of the recovered viruses was compared to the dna ... | 1980 | 6251787 |
| properties of herpes simplex virus type 1 and type 2 dna polymerase. | herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) dna polymerases were highly purified from infected hela bu cells by deae cellulose, phosphocellulose and dna cellulose column chromatography. dna exonuclease activity but not endonuclease activity was found associated with both types of dna polymerase. both dna polymerase activities could be activated by salt in a similar fashion with the optimal activity in the range of ionic strength between 0.22 and 0.29 alpha. at an ionic strength of 0.1 ... | 1980 | 6250618 |
| [effect of the physiological status of culture on herpes simplex virus type 2 infection of synchronized cells bnk-21]. | infecting of synchronized cells-bnk-21 by herpes simplex virus type 2 in the s period resulted in a secondary rise of the labeled cells index and shortened time of the cell cycle as a whole. while infecting of the cells during the s period some morphological transformation was observed. the infecting of the cells in the periods m, g1, g2 revealed no essential changes in cell dna synthesis and failed to result in any cell transformation. | 1980 | 6250284 |
| elution of herpes simplex virus-specific cytotoxic antibodies from squamous cell carcinoma of uterine cervix. | there is evidence that carcinoma of the cervix uteri is associated with infection with herpes simplex virus type 2 (hsv-2), and although indirect evidence suggests an aetiological relationship, this remains controversial. one facet of the problem is that complement-dependent cytotoxic antibodies is hsv-2-infected cells have been undetectable or found only in low titre in sera from patients with progressive cervical cancer whereas higher titres have been found where cervical lesions are less adva ... | 1980 | 6250079 |
| ag-4 complement-fixing antibodies in cervical cancer and herpes-infected patients using local herpes simplex virus type 2. | the incidence of anti-ag-4 complement-fixing antibodies in australian cervical carcinoma (cacx), herpes simplex virus (hsv) type 1 and 2, and control patients, was investigated using local hsv strains. the local hsv strains (both hsv-imi and hsv-2mi) were found, by neutralization experiments, to vary from the american prototype strains. all hsv-2-strains tested were able to induce ag-4 in 4-h infected hep-2 cells. anti-ag-4-complement-fixing antibodies were detected in 40% of dysplasia patients, ... | 1980 | 6249764 |
| cervical carcinoma: detection of herpes simplex virus rna in cells undergoing neoplastic change. | 3h-hsv-2 dna has been hybridized in situ to frozen sectioned tissue from human cervical biopsies. rna complementary to the virus-specific probe was detected in cells undergoing pre-malignant changes, but not in the cells of the fully developed squamous-cell cancer. | 1980 | 6249760 |
| differences in attachment between herpes simplex type 1 and type 2 viruses to neurons and glial cells. | fractions of nerve cell perikarya, synaptosomes, and astrocytic glia were prepared from human, monkey , rabbit, rat, and mouse brain tissue. the herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) binding capacity of these fractions was studied. pretreatment of fractions with one type of hsv and the subsequent testing of adsorption of homotypic and heterotypic virus ws employed to reveal type selectivity of virus binding receptors. a higher density of hsv-1 than of hsv-2 selective receptors w ... | 1980 | 6249749 |
| combination chemotherapy: interaction of 5-methoxymethyldeoxyuridine with adenine arabinoside, 5-ethyldeoxyuridine, 5-iododeoxyuridine, and phosphonoacetic acid against herpes simplex virus types 1 and 2. | the antiviral activity of 5-methoxymethyl-2'-deoxyuridine (mmudr) was compared with that of 5-iodo-2'-deoxyuridine (iudr), 5-ethyl-2'-deoxyuridine (etudr), adenine arabinoside (ara-a), and phosphonoacetic acid (paa) against herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2). mmudr was more potent than ara-a and paa but less active than etudr and iudr against hsv-1 in rabbit kidney (rk-13) cells. in vero cells, the antiviral activities of mmudr, ara-a, and paa against hsv-1 were of the same o ... | 1980 | 6249191 |

| changes in the vaginal cytology of the guinea pig induced by herpes simplex virus. | the vaginal cytology of guinea pigs with genital herpes simplex virus type 2 (hsv-2) infection was examined during acute and latent infection. cytologic changes similar to those observed in humans with hsv-2 genital infections were observed in the guinea pigs during acute infection. during latent infection, some animals continued to have abnormal cytology. the severity of the changes was reduced after treatment with phosphonoformic acid during acute infection. | 1983 | 6223477 |
| immunofluorescent evidence of prior herpes simplex virus type-2 infection in prostate carcinoma. | the finding of herpes simplex virus type-2 (hsv-2) particles in prostatic carcinoma (pca) tissue has led to speculation that the virus might cause this disease. we studied 27 pca and 33 benign prostatic hyperplasia (bph) specimens for the presence of hsv-2 antigens by indirect immunofluorescent staining to hsv-2 using commercially prepared rabbit anti-hsv-2 and fluorescein-tagged goat and anti-rabbit antibody. the slides were randomly number coded by an impartial referee then read independently ... | 1984 | 6209848 |
| clonal analysis of t-cell responses to herpes simplex virus: isolation, characterization and antiviral properties of an antigen-specific helper t-cell clone. | a herpes simplex virus (hsv)-specific long-term t-cell clone has been established from the draining lymph node cells of balb/c mice; the cells required repeated in vitro restimulation with uv-irradiated virus. the established t-cell clone expresses the thy-1 and lyt-1+2,3- surface antigens. for optimal proliferation of the cloned cells, both the presence of specific antigen and an exogenous source of t-cell growth factor are required. the proliferative response of the cloned t cells was found to ... | 1984 | 6209206 |
| immunity to herpes simplex virus type 2. v. risk of recurrent disease following primary infection: modulation of t-cell subsets and lymphokine (lif) production. | phenotypic and functional characteristics of peripheral blood lymphocytes (pbl) from 133 patients (87 female; 46 male) with documented primary or recurrent genital hsv-2 infection were determined by serologic testing and cmi [lymphocyte blastogenesis and lymphokine (lf)] evaluation. primary infection was followed by the development of virus-specific immune memory as defined in vitro by lymphocyte blastogenesis and the development of neutralizing antibody. virus-specific lif production was detect ... | 1983 | 6209056 |
| fine structure analysis of type-specific and type-common antigenic sites of herpes simplex virus glycoprotein d. | the fine structure of the antigenic determinants of herpes simplex virus type 1 and 2 glycoprotein d (gd) was analyzed to determine whether structural differences underlie the differential immunogenicity of these glycoproteins. a region common to herpes simplex virus type 1 and 2 gd (amino acid residues 11 to 19) and two sites specific for herpes simplex virus type 2 gd (one determined by proline at position 7, the other determined by asparagine at position 21) were localized within the n-termin ... | 1984 | 6208376 |
| sensitivity and specificity of monoclonal antibodies directed against antigenic determinants of treponema pallidum nichols in the diagnosis of syphilis. | murine anti-treponema pallidum monoclonal antibodies were employed in studies on sensitivity and specificity of binding to examine their potential for use in the detection of low numbers of pathogenic treponemes present in various body fluids. monoclonal antibodies were used as a primary antibody source in a solid-phase immunoblot assay system. all monoclonal antibodies assayed were capable of detecting ca. 1.0 x 10(3) to 2.5 x 10(3) treponemes. of 13 monoclonal antibodies examined, 3 were able ... | 1984 | 6208218 |
| characterization of mrnas that map in the bglii n fragment of the herpes simplex virus type 2 genome. | the bglii n dna fragment (0.580 to 0.620 map units) of herpes simplex virus type 2 strain (333) is of interest because of its transforming potential. this fragment contains either partial or the complete coding sequences for nine mrna transcripts that can be detected during a lytic infection. subclones of the bglii n dna fragment were generated in plasmid vectors, and the approximate locations of the mrna transcripts were mapped by rna blot hybridization technology. precise 5' or 3' ends (or bot ... | 1984 | 6207312 |
| human cytotoxic t cell clones directed against herpes simplex virus-infected cells. ii. bifunctional clones with cytotoxic and virus-induced proliferative activities exhibit herpes simplex virus type 1 and 2 specific or type common reactivities. | human cytotoxic t lymphocyte (ctl) clones directed against herpes simplex virus (hsv)-infected cells were generated after stimulation of peripheral blood lymphocytes (pbl) with hsv type 1 (hsv-1) and hsv type 2 (hsv-2). these ctl clones were studied with regard to hsv type specificity and with regard to whether they also express helper cell activity. some clones, generated after stimulation with hsv-1, were cytotoxic for autologous cells infected with either hsv-1 or hsv-2 ("hsv type common clon ... | 1984 | 6207243 |
| inhibition of the herpes simplex virus-coded thymidine kinase-complex by 9-beta-d-arabinofuranosyladenine 5'-monophosphate (ara-amp) and 9-(2-hydroxyethoxymethyl)guanine-monophosphate (acyclo-gmp). | the thymidine kinase-complex isolated from herpes simplex virus type 1 and type 2 (hsv-1 and hsv-2) is associated with the following enzyme activities:atp:dthd (dcyd) deoxypyrimidine kinase, atp:dtmp thymidylate kinase, adp:dthd- and amp:dthd 5'-phosphotransferase. in kinetic experiments it is shown that ara-amp inhibits amp:dthd- and adp:dthd phosphotransferase activity, while acyclo-gmp impairs adp:dthd phosphotransferase reaction only; the inhibition was found to be non-competitive. the funct ... | 1984 | 6206825 |
| localization of a type-specific antigenic site on herpes simplex virus type 2 glycoprotein d. | a herpes simplex virus type 1 strain isolated from a recurrent lesion of the nose reacted with monoclonal antibodies recognizing a type 2-specific site on glycoprotein d but not with monoclonal antibodies recognizing other type 2-specific sites. dna sequence analysis of the glycoprotein d gene of the isolate revealed a single nucleotide alteration which changed the codon for asparagine to one encoding histidine at amino acid 97 in the protein. histidine is located at this position in glycoprotei ... | 1984 | 6202883 |
| antiidiotype modulation of herpes simplex virus infection leading to increased pathogenicity. | antiidiotype reagents that recognize idiotypic determinants associated with the combining site of monoclonal antibodies to herpes simplex virus type 2 ( hsv2 ) were used to manipulate the immune response to hsv2 in balb/c mice. the injection of antiidiotype antibodies into mice before challenge with a 50% lethal dose of hsv2 resulted in a shorter survival time than that of mice receiving either preimmune rabbit immunoglobulin g or antiidiotype reagents against hepatitis b surface antigen before ... | 1984 | 6202879 |
| successful use of oligopeptides as immunogens in the preparation of antisera to immediate-early gene products of herpes simplex virus type 1. | antisera to two herpes simplex virus-type 1 (hsv-1) immediate-early gene products ( ie12 and ie175 ) have been produced using oligopeptides, constructed on the basis of proposed dna coding sequences, as immunogens. in both cases the synthetic peptides were linked to bovine serum albumin via an n-terminal tyrosine prior to immunization. both the ie12 and the ie175 antisera reacted with their respective hsv-1 antigens and with antigens produced by the hsv-1 immediate-early mutant tsk but not with ... | 1984 | 6202828 |
| potent synergistic inhibition of herpes simplex virus-2 by 9-[(1, 3-dihydroxy-2-propoxy)methyl]guanine in combination with recombinant interferons. | dhpg, an acyclic guanine nucleoside with the structure 9-[(1,3-dihydroxy-2-propoxy)methyl]guanine], showed potent synergism with recombinant alpha or beta interferons and modest synergism with gamma interferon in inhibiting the replication of herpes simplex virus type 2 in vitro. the most potent direct anti-herpes viral synergism was obtained by combination of dhpg and recombinant human interferon-beta-ser17; when combined, doses of each near their separate effective dose50's resulted in almost ... | 1984 | 6201172 |
| a rapid procedure for the enrichment of undenaturated, antigenically active herpes simplex virus glycoproteins. | the usefulness of lentil lectin affinity chromatography for the rapid enrichment of hsv glycoproteins in an undenatured state for both research and clinical purposes was investigated. in order to compare the lentil lectin-binding characteristics and immunologic specificities of undenatured hsv-1 and hsv-2 glycoproteins, [35s]methionine-labelled extracts of virus-infected hep-2 cells were subjected to lentil lectin affinity chromatography. individual hsv-1 and hsv-2 glycoproteins in bound and unb ... | 1984 | 6200489 |
| identification and preliminary mapping with monoclonal antibodies of a herpes simplex virus 2 glycoprotein lacking a known type 1 counterpart. | the properties of herpes simplex virus 2 (hsv-2)-specific proteins reactive with monoclonal antibody h966 derived from mice immunized with hsv-2 strain g are reported. the reactive proteins contained in infected cell lysates subjected to electrophoresis in denaturing gels and transferred to nitrocellulose sheets form a relatively sharp band characteristic of mr 124,000 proteins and a diffuse, more slowly migrating band. antigens reactive with h966 were detected on the surface of viable, unfixed ... | 1984 | 6199891 |
| localization and synthesis of an antigenic determinant of herpes simplex virus glycoprotein d that stimulates the production of neutralizing antibody. | an antigenic determinant capable of inducing type-common herpes simplex virus (hsv)-neutralizing antibodies has been located on glycoprotein d (gd) of hsv type 1 (hsv-1). a peptide of 16 amino acids corresponding to residues 8 to 23 of the mature glycoprotein (residues 33 to 48 of the predicted gd-1 sequence) was synthesized. this peptide reacted with an anti-gd monoclonal antibody (group vii) previously shown to neutralize the infectivity of hsv-1 and hsv-2. the peptide was also recognized by p ... | 1984 | 6197535 |
| comparison of the antiviral effects of 5-methoxymethyldeoxyuridine-5'-monophosphate with adenine arabinoside-5'-monophosphate. | methoxymethyldeoxyuridine-5'-monophosphate (mmudr-mp) and arabinofuranosyladenine-5'-monophosphate (ara-amp) had significant antiviral activity against herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) in rk-13 and vero cells. mmudr-mp and ara-amp were more potent than methoxymethyldeoxyuridine (mmudr) and arabinofuranosyladenine (ara-a) against the ms strain of hsv-2. mmudr-mp inhibited replication of hsv-1r (mutant resistant to mmudr). mmudr in combination with ara-amp showed additive act ... | 1983 | 6197027 |
| x-linked resistance of mice to high doses of herpes simplex virus type 2 correlates with early interferon production. | mice inoculated intraperitoneally with herpes simplex virus type 2 develop focal necrotizing hepatitis and eventually die from ascending myelitis and encephalitis. the genetics of resistance to the infection were analyzed in crosses between resistant c57bl/10 mice and susceptible balb/c mice. it was shown that the resistance of c57bl/10 mice to hepatitis induction was influenced by an x-linked dominant gene as previously shown for the gr mouse strain. the course of infection in the liver pointed ... | 1983 | 6196293 |
| mode of protection of mice against herpes simplex virus type 2 infection by propionibacterium. | we compared various strains of propionibacterium with regard to protection of young adult mice against lethal infection with herpes simplex virus type 2 (hsv-2). propionibacterium acnes, p. granulosum, and p. avidum were protective, while p. acidi-propionici and p. lymphophilum were ineffective. the protective effect proved to be in the cell wall fraction. attempts were made to elucidate possible mechanisms of the protection using both effective and ineffective strains. the results strongly sugg ... | 1983 | 6195512 |
| characterization of a herpes simplex virus type 2 75,000-molecular-weight glycoprotein antigenically related to herpes simplex virus type 1 glycoprotein c. | evidence is presented that the herpes simplex virus type 2 glycoprotein previously designated gf is antigenically related to herpes simplex virus type 1 gc (gc-1). an antiserum prepared against type 1 virion envelope proteins immunoprecipitated gf of type 2 (gf-2), and competition experiments revealed that the anti-gc-1 component of the antiserum was responsible for the anti-gf-2 cross-reactivity. an antiserum prepared against fully denatured purified gf-2, however, and three anti-gf-2 monoclona ... | 1983 | 6194310 |
| herpes simplex virus type 2 glycoprotein gf and type 1 glycoprotein gc have related antigenic determinants. | the 104-s monoclonal antibody immunoprecipitated from herpes simplex virus type 2 (hsv-2)-infected cell extracts the 75,000-molecular-weight glycoprotein gf and its 65,000-molecular-weight precursor (pgf). the precursor pgf was sensitive to endoglycosidase h digestion, indicating the presence of high mannose-type oligosaccharides, whereas the stable gf product was sensitive to neuraminidase digestion, indicating the presence of sialic acid residues. the 104-s antibody also weakly precipitated th ... | 1983 | 6191040 |
| rapid and selective shutoff of plasma protein production in herpes simplex virus type 2-infected hepatoma cells. | the effect of herpes simplex virus type 2 (hsv-2) infection of hepatoma mca-rh7777 cells on the production of alpha-fetoprotein (afp) and several other secreted plasma proteins was examined. cells infected with hsv-2 were labeled with [35s]methionine for various times postinfection (p.i.). culture media and intracellular extracts were immunoprecipitated with plasma protein antibodies and examined by polyacrylamide gel electrophoresis. the relative levels of afp and several other plasma proteins ... | 1983 | 6190309 |
| a micro solid-phase radioimmunoassay for detection of herpesvirus type-specific antibody: specificity and sensitivity. | the specificity and sensitivity of a micro solid-phase radioimmunoassay (micro-spria) that detects type-specific igg antibody to herpes simplex virus types 1 and 2 (hsv1 and hsv2) were evaluated. glycoproteins vp123 (molecular weight, 123,000) of hsv1 and vp119 (molecular weight, 119,000) of hsv2 were found to display the greatest degree of antigenic type-specificity of several hsv antigens tested with the micro-spria technique. when testing a group of sera, negative for anti-hsv antibodies by m ... | 1983 | 6189849 |
| a micro solid-phase radioimmunoassay for detection of herpesvirus type-specific antibody: parameters involved in standardization. | a micro solid-phase radioimmunoassay (micro-spria) was developed to demonstrate type-specific antibodies to herpes simplex virus types 1 and 2 (hsv1 and hsv2). glycoproteins from the 123,000 dalton region of hsv1 (vp123) and the 119,000 dalton region of hsv2 (vp119) were isolated on preparative polyacrylamide gels for use as antigens in the micro-spria. human sera selected from clinical samples by virological history and appropriate microneutralization data were used to standardize the micro-spr ... | 1983 | 6189848 |
| human cytomegalovirus and herpes simplex type 2 virus in normal and adenocarcinomatous prostate glands. | normal prostate, benign prostate hypertrophy (bhp), and prostate adenocarcinoma (acp) biopsy specimens were analyzed for the presence of human cytomegalovirus (hcmv) and herpes simplex virus type 2 (hsv-2)-specific macromolecules. hcmv dna homologous sequences were detected in 2 of 13 normal prostate, 2 of 9 bhp, and 3 of 10 acp tissues, and hsv-2 dna homologous sequences were found in 1 normal prostate tissue and 2 acp tissues. in situ dna-rna hybridizations indicated hcmv-specific rna in 3 of ... | 1983 | 6188872 |
| antigenic variants of herpes simplex virus selected with glycoprotein-specific monoclonal antibodies. | monoclonal antibodies specific for herpes simplex virus type 1 (hsv-1) glycoproteins were used to demonstrate that hsv undergoes mutagen-induced and spontaneous antigenic variation. hybridomas were produced by polyethylene glycol-mediated fusion of p3-x63-ag8.653 myeloma cells with spleen cells from balb/c mice infected with hsv-1 (strain kos). hybrid clones were screened for production of hsv-specific neutralizing antibody. the glycoprotein specificities of the antibodies were determined by sod ... | 1983 | 6187935 |
| characteristics of a shared idiotype by two igm anti-herpes simplex virus monoclonal antibodies that recognize different determinants. | two igm monoclonal antibodies (mcab) that recognized distinct antigenic determinants of herpes simplex virus type 2 (hsv2) were shown to share idiotypes. seven other igm mcab generated to either hsv2 or the major envelope glycoprotein of hsv2, vp119, did not express this shared idiotype. the idiotypic determinants were associated with the antibody-combining site, because hsv2 inhibited the idiotype-anti-idiotype reactions. anti-hsv2 sera raised in balb/c mice also expressed the idiotype shared b ... | 1983 | 6187827 |
| hla-restricted t lymphocyte-mediated cytotoxicity against herpes simplex virus-infected cells in humans. | cytotoxic t lymphocytes (ctl) against herpes simplex virus (hsv) were induced in vitro from human peripheral blood lymphocytes by stimulation with hsv antigen. ctl generated by hsv type 1 (hsv-1) antigen stimulation killed not only hsv-1-infected target cells but also hsv type 2 (hsv-2)-infected target cells, though at a lower level. this evidence suggests that ctl against hsv recognize the hsv type-specific and type-common determinants on hsv-infected target cells. these ctl were generated from ... | 1983 | 6187690 |
| experimental infection of inbred mice with herpes simplex virus. iv. comparison of interferon production and natural killer cell activity in susceptible and resistant adult mice. | inbred mouse strains differ in susceptibility to infection with herpes simplex virus type 1 or type 2 (hsv-1, hsv-2). in this study interferon production was tested in the peritoneal exudate of mice after intraperitoneal (i.p.) injection of hsv-1 or hsv-2. in hsv-resistant mice (c57 bl/6, c3 h/hej) high titers of interferon were already present 2 to 4 hours after injection. in comparison, less resistant mice (dba/2, akr) lacked this early response. there was no correlation between interferon tit ... | 1982 | 6187314 |
| herpes simplex infection simulating a positive auto-inoculation for haemophilus ducreyi. | auto-inoculation from a genital ulcer suspected of being ulcus molle gave redness after 24 hours and after 48 hours vesicles and pustules appeared. cultivation from the auto-inoculation after the 48 hours was positive for herpes simplex virus type 2. our observation underlines two points: auto-inoculation for the diagnosing of haemophilus ducreyi infection may be mimicked by herpes simplex infection, and the incubation period of herpes simplex can be shorter than the 4-5 days usually given. | 1982 | 6183910 |
| effect of combinations of acyclovir with vidarabine or its 5'-monophosphate on herpes simplex viruses in cell culture and in mice. | the combination of various concentrations of acyclovir and vidarabine or its 5'-monophosphate usually produced an additive interaction with various strains of herpes simplex virus types 1 and 2 in vero cells. similarly, certain combinations of these drugs were more effective than the individual drugs in decreasing the mortality and increasing the mean day of death of mice inoculated intracerebrally with herpes simplex virus type 2. neither antagonism nor interference was noted for any of the in ... | 1982 | 6182836 |
| anti-herpesvirus activity of adenine arabinoside analogues in tissue culture and a genital infection of mice and guinea pigs. | four analogues of adenine arabinoside (ara-a) were compared for activity against herpes simplex virus (hsv) in tissue culture and in a genital infection of mice and guinea pigs. these analogues, 5'-monophosphate (ara-amp), 5'-valerate ester (ara-av), 2'3'-diacetate ester (ara-ada), and 2',3',5'- triacetate ester (ara-ata) have greater water and lipid solubility and resistance to deamination than ara-a. in mouse embryo fibroblast cells, similar viral inhibitory levels were noted with ara-a, amp, ... | 1982 | 6179469 |
| protease inhibitors suppress fibrinolytic activity of herpesvirus-transformed cells. | previous studies in this laboratory have quantified the fibrinolytic activity of herpesvirus-transformed cell lines and implicated the proteolytic capacity of cloned cell lines in the formation of primary and metastatic tumours. because of the involvement of proteases in tumourigenesis in this system, we examined the effect of various protease inhibitors (alpha-1-antitrypsin, leupeptin and alpha-2-macroglobulin), as well as hamster serum containing acute phase proteins generated in response to p ... | 1982 | 6178796 |
| effect of monoclonal antibodies on limited proteolysis of native glycoprotein gd of herpes simplex virus type 1. | we examined the properties of 17 monoclonal antibodies to glycoprotein gd of herpes simplex type 1 (hsv-1) (gd-1) and hsv-2 (gd-2). the antibodies recognized eight separate determinants of gd, based on differences in radioimmuno-precipitation and neutralization assays. the determinants were distributed as follows: three were gd-1 specific, one was gd-2 specific, and four were type common. several type-specific and type-common determinants appeared to be involved in neutralization. we developed a ... | 1982 | 6176725 |
| herpes simplex virus type 1 and 2 intracellular p40: type-specific and cross-reactive antigenic determinants on peptides generated by partial proteolysis. | intracellular p40 is a class of protein ranging in molecular weight from 39,000 to 45,000 that is immunoprecipitated from herpes simplex virus type 1 (hsv-1)- and hsv-2-infected cell extracts by mouse monoclonal antibodies or guinea pig antisera against hsv-1 and hsv-2 nucleocapsid p40. analysis by a two-dimensional gel system showed that hsv-1 and hsv-2 intracellular p40 each consisted of three major components. however, these hsv-1 and hsv-2 proteins differed in charge and size. analysis of st ... | 1981 | 6172597 |
| characteristics of a persistent rubella infection in a human cell line. | a persistent infection of the human mcf-7 cell line (mcf-7rv) was established with the dbs strain of rubella virus at a low multiplicity of infections. fluorescent antibody staining revealed that 100% of the cells were positive for rubella antigens. the infected cells were refractory to superinfection with vesicular stomatitis virus (vsv) but were susceptible to herpes simplex virus type 2 (hsv-2). no interferon could be detected in infected cell culture fluid, and continuous passage in the pres ... | 1981 | 6169785 |
| monoclonal antibodies to two glycoproteins of herpes simplex virus type 2. | monoclonal antibodies to herpes simplex virus type 2 were found to precipitate different numbers of radiolabeled polypeptides from lysates of virus-infected cells. antibodies directed against two viral glycoproteins were characterized. antibodies from hybridoma 17 alpha a2 precipitated a 60,000-molecular-weight polypeptide which chased into a 66,000- and 79,000-molecular-weight polypeptide. all three polypeptides labeled in the presence of [3h]glucosamine and had similar tryptic digest maps. the ... | 1981 | 6168775 |
| detection of rna complementary to herpes simplex virus dna in human cervical squamous cell neoplasms. | nonneoplastic and neoplastic cervical biopsy specimens were examined by in situ hybridization to 125i-labeled dna of herpes simplex virus (hsv), adenovirus, and bacteriophage lambda dna's, and quantitative hybridization data were obtained using a video image analyser. hsv-specific rna was detected in 72% of cervical intraepithelial neoplasia, 60% of squamous cervical carcinomas, 2% of nonneoplastic cervices, and 9% of primary adenocarcinomas of the cervix. none of the tissues gave positive hybri ... | 1981 | 6167349 |
| comparison of the effects of arabinosyladenine, arabinosylhypoxanthine, and arabinosyladenine 5'-monophosphate against herpes simplex virus, varicella-zoster virus, and cytomegalovirus with their effects on cellular deoxyribonucleic acid synthesis. | in a single line of human foreskin fibroblasts, minimum inhibitory concentrations (mics) and the minimum intracellular virus inactivation concentrations (miics) of arabinosyladenine, arabinosylhypoxanthine, and arabinosyladenine 5'-monophosphate were assayed for a number of recent isolates of herpes simplex virus types 1 and 2 (hsv-1, hsv-2), varicella-zoster virus (vzv), and cytomegalovirus (cmv). (the term miic is used here to describe the selective qualitative intracellular inhibition of the ... | 1981 | 6166244 |
| function, target-cell preference and cell-surface characteristics of herpes-simplex virus type-2-induced non-antigen-specific killer cells. | wild-type and congenitally athymic nude mice injected with herpes-simplex virus type 2 (hsv 2) responded with a local outburst of non-antigen-specific killer cells masking any virus-specific response. cytolytic activity could be assayed on mouse-tumor cell lines and on syngeneic or allogeneic non-transformed cells from various sources. some of the tumor cell lines and proteose-peptone-induced peritoneal exudate cells were lysed more efficiently after infection with either hsv 2, vaccinia or infl ... | 1981 | 6165679 |
| glycoproteins with type common and type specific antigenic sites excreted from cells infected with herpes simplex virus types 1 and 2. | agar immunodiffusion tests demonstrated that bhk 21 cells infected with either hsv i or hsv 2 release only a few hsv-specified antigens into the extracellular fluid (infected cell released polypeptides-icrp). neutralization blocking experiments showed that the majority of antigens/(including the band ii common antigen) involved as target sites in antibody-mediated virus neutralization are present in the icrp of both hsv i and hsv 2.sds-page identified six regions of virus-specified proteins in t ... | 1980 | 6156995 |
| structural analysis of the capsid polypeptides of herpes simplex virus types 1 and 2. | capsids of herpes simplex virus (hsv) types 1 and 2 contain seven polypeptides ranging in molecular weight from 154,000 to 12,000 (termed nc-1 through nc-7 in order of descending molecular weight). antibodies prepared to hsv-1 capsid polypeptides isolated from sodium dodecyl sulfate-polyacrylamide gels reacted in an immunofluorescence assay against hsv-1-infected kb cells. three of the antibodies (anti-nc-1, anti-nc-2, and anti-nc-3,4) also reacted with hsv-2-infected cells. tryptic peptide anal ... | 1980 | 6154808 |
| biochemical transformation of mouse cells by a purified fragment of marmoset herpesvirus dna. | although the size of marmoset herpesvirus (marhv) dna, estimated by velocity sedimentation in sucrose gradients, was similar to that of herpes simplex virus type 1 (hsv-1) dna, the restriction endonuclease sites of marhv and hsv-1 dnas were quite different. a specific bamhi restriction fragment (6.2 x 10(6) daltons) of marhv dna biochemically transformed lm(tk-) mouse fibroblasts to the thymidine kinase(tk)-positive phenotype. rabbit antisera, prepared against marhv tk, inhibited marhv-induced t ... | 1980 | 6154671 |
| inhibition of herpes simplex virus type 2-induced biochemical transformation by interferon. | the effect of interferon on the biochemical transformation of thymidine kinase-deficient cells by uv-inactivated herpes simplex virus type 2 has been studied. transformation was much less sensitive to the action of interferon than virus multiplication. however, the continuous presence of a high dose of interferon (2,000 u) inhibited transformation almost completely. although we could not differentiate between the effect of interferon on fixation and expression of the virus thymidine kinase gene, ... | 1980 | 6154151 |
