assay of type-specific and type-common antibodies to herpes simplex virus types 1 and 2 in human sera.a reliable and reproducible method for determining specific reactivity to herpes simplex virus types 1 and 2 (hsv-1 and hsv-2) in human sera has been developed. human sera were used to immunoprecipitate hsv-specific glycoprotein antigens from both hsv-1- and hsv-2-infected cell extracts. the viral glycoproteins precipitated from these extracts were then analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis to detect specific reactivity of the sera with distinct type-specific anti ...19816262247
production of hybrid cell lines secreting antibodies to herpes simplex virus type 2.following different immunization schedules we have produced 102 myeloma--spleen cell hybrid lines (30.8% of the total) secreting antibodies to hsv-2 infected cells. the highest yield of hybrids was derived from fusion of myeloma cells with spleen cells from mice sensitized by footpad injection of formalin-inactivated virus and boosted intravenously with the same antigen. to date, twelve of the antibody-producing hybrids have been cloned by limiting dilutions to generate over 100 monoclonal lines ...19816262346
involvement of an early human cytomegalovirus function in reactivation of quiescent herpes simplex virus type 2.we have previously described an in vitro system in which the function lacking for herpes simplex virus type 2 (hsv-2) replication can be induced by human cytomegalovirus (hcmv). the mechanism of this reactivation of quiescent hsv-2 by hcmv has been further defined. the hcmv function(s) responsible for hsv-2 stimulation was examined temporally, and the fraction of cells in quiescent cultures producing hsv-2 after superinfection was determined. using independent biological, genetic and molecular t ...19816262523
aminoacyl fucosides as possible biochemical markers at tumorigenic and metastatic potential in herpes simplex virus type 2-transformed rat cells.two classes of aminoacyl fucosides termed fl3 and fl4 were studied as possible markers of tumorigenic and metastatic potential in herpes simplex virus type 2 transformed rat cells. in the present study, clonal cell lines of transformed highly tumorigenic and metastatic (t-ref-g-1.1), weakly tumorigenic and nonmetastatic (t-ref-g-2.1), nontumorigenic (t-ref-g-2.0), and secondary nontransformed rat embryo fibroblast cells were labeled with [3h]fucose, and cell extracts were analyzed for ratio of r ...19816266657
herpes virus inactivation by chemical carcinogens: differential inactivation of herpes simplex viruses by 4-nitroquinoline 1-oxide and related compounds.treatment of stocks of herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) with the chemical carcinogen 4-nitroquinoline 1-oxide (nqo) resulted in inactivation of virus infectivity at rates which were directly dependent on the concentration of nqo and interval of exposure to nqo. hsv-1 strains were more sensitive than hsv-2 strains to inactivation by nqo, although survival curves of both hsv types were multicomponent. exposure of hsv-2 to a related group of chemicals suggested that the struct ...19816266824
complement-fixing antibody to the ag-4 antigen in herpes simplex virus type 2-infected patients.sera collected from confirmed herpes simplex virus type 2 (hsv-2) patients were found to be devoid of complement-fixing antibody to the ag-4 antigen at the time of the herpes lesion outbreak in 10 out of 13 cases. however, 1 to 4 weeks after hsv-2 lesion appearance, 28 out of 30 patients acquired complement-fixing antibody to the ag-4 antigen. the sera of these patients contained immunoglobulin m antibody activity and the ability to immunoprecipitate a 160,000-molecular weight early hsv-2 antige ...19816266964
latency in vitro using irradiated herpes simplex virus.human embryonic fibroblasts infected with u.v.-irradiated herpes simplex virus type 2 (hsv-2, strain 186) and maintained at 40.5 degrees c did not yield detectable virus. virus synthesis was induced by temperature shift-down to 36.5 degrees c. the induced virus grew very poorly and was inactivated very rapidly at 40.5 degrees c. non-irradiated virus failed to establish latency at 40.5 degrees c in infected cells. enhanced reactivation of hsv-2 was observed when latently infected cultures were su ...19816267167
physical mapping of temperature-sensitive mutations of herpes simplex virus type 2 by marker rescue.the physical mapping of six ts mutations of herpes simplex virus type 2 (hsv-2) is presented. the results were obtained from 14 separate intratypic marker rescue experiments and the analysis of 20 hsv-1/hsv-2 intertypic recombinants. the order of these mutations on the physical map of hsv-2 is unambiguous and correlates almost exactly with the previously published genetic map of timbury & calder (1976). one of the mutants studied (hsv-2 ts12) has apparently two distinct conditionally lethal ts m ...19816267168
experimental studies of acute and recurrent herpes simplex virus infections in the murine heart and dorsal root ganglia.the multiplication of hsv-1 and hsv-2 strains in the heart and the corresponding dorsal root ganglia (drg) was examined in experimentally infected mice. infectious hsv-1 was recovered from the heart between the second and fourth day after inoculation and 3 days later from the drg. both the heart and drg yielded infectious hsv-2 from the fourth to the twenty-first day after inoculation. the hsv-2, but not the hsv-1, induced recrudescent disease in chronically infected mice up to 18 months after i ...19816267190
[new antigens induced by herpes simplex virus in human tumors].tissues of malignant tumors of the genitalia (cervix, uterus body, ovary) contain a specific antigen associated with herpes simplex virus type 2 (hsv-2) identical with the antigen of the infected cells. the virus-induced antigen was detected in tissues of cervical carcinoma in 35% of cases, in 15% of tumors of the corpus uteri and in 13% of ovary tumors. hsv-2 was isolated from pathologically altered cervical carcinoma cells in 2 out of 56 cases examined. these facts indicate the presence of hsv ...19816267821
differentiation of members of the human herpesviridae family by radioimmunoassay.many individuals who are seronegative for one member of the human herpesviridae family are strongly seropositive for other members. using sera from such individuals, the radioimmunoassay technique demonstrated absence of antigen-antibody cross-reactions between varicella-zoster virus (vzv) and herpes simplex virus (hsv) at levels of less than one part in 1,000. sera containing antibody to both hsv and vzv were absorbed with antigens of one agent without significantly altering the amount of remai ...19816268545
protectivity of herpes simplex virus antigens: studies in mice on the adjuvant effect of piclc and on the dependence of protection on t cell competence.the efficacy of a herpes simplex virus type 1 (hsv-1) envelope antigen (eag) preparation against hsv infection was studied in t cell competent and t cell deficient mice. immuno-competent mice were successfully protected against herpes simplex virus type 1 (hsv-1) or type 2 (hsv-2) infection when immunized 2 weeks prior to this infection with a heat-inactivated whole virus preparation or a hsv-1 envelope antigen (hsv-1 eag) preparation. since hsv-1 eag was considerably less effective than the who ...19816268955
the influence of different modes of immunization on the experimental genital herpes simplex virus infection of mice.previous investigations, which simulated the usual sequence of the human herpes simplex virus (hsv) infections, had shown that the oral infection of mice with hsv-1 caused only weak protection from genital infection with hsv-2, although the course of infection was attenuated and lethality diminished. this heterologous, heterotopic model was compared with a homologous, heterotopic and a heterologous, homotopic model. the results did not differ very much, although the homologous immunization prote ...19816268958
antiherpesviral and anticellular effects of 1-beta-d-arabinofuranosyl-e-5-(2-halogenovinyl) uracils.1-beta-d-arabinofuranosyl-e-5-(2-bromovinyl) uracil (bv-ara-u) and 1-beta-d-arabinofuranosyl-e-5-(2-chlorovinyl)uracil (cv-ara-u) were tested for their anti-herpesviral activity in virus rating method, a plaque reduction method, and a virus yield reduction method, using human embryonic lung fibroblast (hel-f) cells, at a concentration as low as 0.1 microgram/ml, both drugs exerted a marked inhibitory effect on the development of cytopathogenic effect induced by herpes simplex virus type 1 (hsv-1 ...19816269482
induction of uterine cancer with inactivated herpes simplex virus, types 1 and 2.a series of studies were performed to evaluate the oncogenic potential of inactivated herpes simplex viruses types 1 (hsv-1) and 2 (hsv-2) in the mouse cervix. hsv-1 or hsv-2 prepared in hep-2 cell cultures and inactivated by exposure to formalin or ultraviolet light was applied to the mouse cervix for periods ranging from 20 to 90 weeks. control mice were exposed for the same period to control fluids. vaginal cytologic preparations from all animals were examined weekly to detect epithelial abno ...19816269724
recovery of mice from herpes simplex virus type 2 hepatitis: adoptive transfer of recovery with immune spleen cells.young balb/c mice inoculated intraperitoneally with herpes simplex virus type 2 develop focal necrotizing hepatitis. after infection, the livers of these mice show increasing virus titers, which reach a maximum on day 3 after infection; this is followed by a dramatic decrease in the amount of virus recovered on days 4 and 5. this decrease in virus content is accompanied by a progressive infiltration of the lesions with mononuclear leukocytes and an apparent resolution of the lesions. adoptive tr ...19816269998
conversion of herpetic lesions to malignancy by ultraviolet exposure and promoter application.many lines of evidence exist associating herpes simplex virus (hsv) with the development of carcinoma, but much of this evidence is anecdotal or associative in nature and does not prove a cause and effect. the purpose of this research was to investigate the oncogenic potential of hsv type 2 (hsv-2) in vivo. a mouse model for lip carcinogenesis was designed to combine hsv-2 infection, u.v. exposure and tetradecanoyl-phorbol-acetate (tpa) application. hsv-2 inoculation on to abraded mouse lips was ...19816270265
nucleotide sequences of the joint between the l and s segments of herpes simplex virus types 1 and 2.the a sequence of herpes simplex virus (hsv) is present as a direct repeat at the genomic termini and also in inverted orientation at the joint between the l and s segments. dna sequences have been determined for the joint regions of the genomes of hsv-1 and hsv-2, and relative to these sequences the genomic termini are in both cases located close to a short direct repeat of 17 to 21 base pairs (bp) at the b-a and a-c junctions. the hsv-1 joint region contains three separate tandem direct reiter ...19816270266
physical mapping of drug resistance mutations defines an active center of the herpes simplex virus dna polymerase enzyme.the genome structures of herpes simplex virus type 1 (hsv-1)/hsv-2 intertypic recombinants have been previously determined by restriction endonuclease analysis, and these recombinants and their parental strains have been employed to demonstrate that mutations within the hsv dna polymerase locus induce an altered hsv dna polymerase activity, exhibiting resistance to three inhibitors of dna polymerase. the viral dna polymerases induced by two recombinants and their parental strains were purified a ...19816270349
nonstructural proteins of herpes simplex virus. ii. major virus-specific dna-binding protein.the major herpes simplex virus type 2 dna-binding infected cell-specific polypeptides 11 and 12 have been purified to homogeneity from extracts of virus-infected cells. monospecific antiserum to the purified protein has been made and used to examine virus temperature-sensitive mutants for defects in the synthesis of the protein and to probe virus dna synthesis in isolated chromatin. the purified protein acted directly on a polydeoxyadenylic acid-polydeoxythymidylic acid helix, reducing its melti ...19816270358
identification of a virus-specific polypeptide associated with a transforming fragment (bglii-n) of herpes simplex virus type 2 dna.the bglii n fragment of herpes simplex virus type 2 (hsv-2) dna (approximately 0.58 to 0.63 map unit) was examined for encoded products. using plasmid pgz59, which consists of bglii-n cloned in pat153, in conjunction with hybrid arrested translation, mrna selection, and in vitro protein synthesis, we found that the major translated product of this region has an approximate molecular weight of 37,800. by further mapping, coding sequences for this polypeptide were located within the region of bgli ...19816270369
herpes simplex virus types 1 and 2 completely help adenovirus-associated virus replication.in addition to adenoviruses, which are capable of completely helping adenovirus-associated virus (aav) multiplication, only herpesviruses are known to provide any aav helper activity, but this activity has been thought to be partial (i.e., aav dna, rna, and protein syntheses are induced, but infectious particles are not assembled). in this study, however, we show that herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) are in fact complete aav helpers and that aav type 2 (aav2) infectivity yi ...19816270377
focus formation and neoplastic transformation by herpes simplex virus type 2 inactivated intracellularly by 5-bromo-2'-deoxyuridine and near uv light.the induction of focus formation in low serum and of neoplastic transformation of syrian hamster embryo cells was examined after the expression of herpes simplex virus type 2 functions. syrian hamster embryo cells infected at a high multiplicity (5 pfu/cell) with 5-bromo-2'-deoxyuridine-labeled herpes simplex virus type 2 (11% substitution of thymidine residues) were exposed to near uv light irradiation at various times postinfection. this procedure specifically inactivated the viral genome, whi ...19816270382
phospholipid synthesis in human embryo fibroblasts infected with herpes simplex virus type 2.the effect of herpes simplex virus type 2 infection on the synthesis of phospholipids in human embryo fibroblasts was determined at temperatures permissive (35 c) or nonpermissive (42 c) for virus replication. incorporation of [32p]i was decreased by herpes simplex virus type 2 infection after 6 hr, which corresponds to the time of initiation of progeny virus production. no differences were observed in the relative incorporation of [32p]i phospholipid classes. in another series of experiments ce ...19816270493
in vitro studies of a co-carcinogenic effect of vaccinia and herpes group viruses.the results of studies of a co-carcinogenic effect of two human infectious viruses in tissue culture are reported here. viable vaccinia virus actively replicating in the cells of primary balb/c tissue culture and in a number of continuous murine cell lines has been shown to induce in them expression of major structural p30 protein of murine retroviruses. vaccinia virus has been also shown to cause biochemical transformation of murine cells. evidence for the capacity of herpes simplex virus type ...19816270580

specific lymphocyte blastogenic responses in children with cytomegalovirus and herpes simplex virus infections acquired early in infancy.cell-mediated immune responses in 27 infants and children with cytomegalovirus (cmv) infection acquired between birth and 1 year of age were compared with responses in 13 children who had neonatal herpes simplex virus (hsv) infection. infection was asymptomatic in 25 of 27 cmv-infected children; the 13 patients with hsv infection were all ill as newborns. the median age when studied was 46 months for children infected with cmv and 24 months for those infected with hsv. we measured lymphocyte tra ...19816271679
use of monoclonal antibody directed against herpes simplex virus glycoproteins to protect mice against acute virus-induced neurological disease.monoclonal antibodies hcl and hd1, directed against herpes simplex virus type 1 (hsv-1) glycoproteins gc and gd, respectively, were evaluated for their ability to passively immunize mice against acute virus-induced neurological disease after footpad inoculation with hsv-1 or herpes simplex virus type 2 (hsv-2). control virus-infected mice receiving a single intraperitoneal injection of normal serum died within 7 to 10 days after the spread of virus from footpad to spinal cord and brain. however, ...19816271681
ocular lesions associated with dissemination of type 2 herpes simplex virus from skin infection in newborn rabbits.the subcutaneous inoculation of the backs of new zealand white rabbits 17 to 34 hr old with 10(3) 50% tissue culture infection dose (tcid50) of type 2 herpes simplex virus (hsv-2) induced cutaneous lesions within 24 hr, foci of disseminated infection in many organs (including the eye) on day 3 and thereafter, and the death of the animals on day 5 with infection of the central nervous system. infectious hsv-2 could be isolated from the mononuclear cells and plasma of the peripheral blood, indicat ...19816271702
the detection of dna tumour virus-specific rna sequences in abnormal human cervical biopsies by in situ hybridization.we have used the technique of in situ nucleic acid hybridization and autoradiography of thin frozen sections of human tissue to search for virus rna sequences in human cervical tumours. of cervical biopsies with abnormal cytology, 67% bound herpes simplex virus type 2 (hsv2) 3h-labelled dna probes and 39% bound adenovirus type 2 (ad2) 3h-labelled dna probes, whereas control experiments with phage lambda 3h-labelled dna probes, under the same conditions, bound to only 7% of cases. in contrast, no ...19816271899
one functional copy of the long terminal repeat gene specifying the immediate-early polypeptide ie 110 suffices for a productive infection of human foetal lung cells by herpes simplex virus.the hsv-1/hsv-2 intertypic recombinant bx1 (28-1) is heterotypic for the repeat sequences flanking the long unique region of the genome (irl and trl) and expresses both the immediate-early polypeptide ie 110 of hsv-1 and its functionally equivalent polypeptide ie 118 of hsv-2. the genome structures of five subclones of this recombinant and the immediate-early polypeptides they induce have been analysed. subclone 14 lacked most of the irl sequence, including the region from which part of the mrna ...19816271901
differential immunologic reactivity and processing of glycoproteins ga and gb of herpes simplex virus types 1 and 2 made in vero and hep-2 cells.herpes simplex virus types 1 and 2 (hsv-1 and hsv-2, respectively) specify five major glycoproteins designated as ga, gb, gc, gd, and ge. previous studies have shown that ga and gb differ in electrophoretic mobility but not in reactivity with antisera prepared to each of these glycoproteins. moreover, ga and gb of hsv-1 crossreact in serologic tests with the corresponding glycoproteins of hsv-2. in this paper, we report on the reactivities of ga and gb of hsv-1 and hsv-2 with 24 independently de ...19816272294
consistent appearance of microtubules in cells productively infected with various strains of type 2 herpes simplex virus.electron microscopic examination showed microtubular structures in fl cells infected with all 18 strains of hsv-2 examined, but not in cells infected with 9 strains of hsv-1. these structures were also detected in other cultured cells (vero and earle's l cells) infected with hsv-2, and also in vivo in cells, such as neuronal cells of the spinal ganglia and liver cells, of one-day-old suckling mice (ddd strain) infected with this type of virus. thus the microtubules were consistently detected in ...19816272691

kaposi's sarcoma. iv. detection of cmv dna, cmv rna and cmna in tumor biopsies.in order to determine whether human cytomegalovirus- (cmv) dna homologous sequences as well as cmv-specific rna(s) and antigen(s) exist in tumor biopsies of kaposi's sarcoma (ks) dna-dna reassociation, rna-dna in situ cytohybridization and anticomplement immunofluorescence test (acif) tests were applied. three of 10 dnas extracted from kaposi sarcoma biopsies contained dna sequences homologous to radioactively labelled human cmv dna probe. the amount of cmv dna in these sarcoma tissues was calcu ...19816273333
evaluation of the antiherpetic activity of 2'-fluoro-5-iodo-ara-c in rabbit eyes and cell cultures.2-fluoro-5-iodo-ara-c (fiac), a new and potent drug, was tested for antiviral activity against several strains of herpes simplex virus (hsv), types 1 and 2. effective dose-50% (ed-50) determinations for fiac ranged from 0.023 to 0.51 mum for hsv-2. fiac-treated cells did not exhibit any toxicity until the drug concentration was increased 2000-fold above the ed-50 level. ocular herpetic keratitis in new zealand white rabbits was treated with 1.0%, 0.1%, 0.01% fiac beginning 3 days after inoculati ...19816273355
differences in neurovirulence among isolates of herpes simplex virus types 1 and 2 in mice using four routes of infection.differences in neurovirulence between herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) were investigated using recent clinical isolates and laboratory-passaged strains in intravaginal, intranasal, intraperitoneal, and intracerebral infections of mice. the hsv-2 isolates caused higher death rates in all four infections. no differences in death rate were observed between recent and passaged isolates of either hsv-1 or hsv-2. after intravaginal inoculation, hsv-1 isolates replicated to higher ...19816273475
repression and activation of the genome of herpes simplex viruses in human cells.we have described previously a cell culture system in which the herpes simplex virus (hsv) type 2 (hsv-2) genome is maintained in a repressed form after treatment of infected cells with 1-beta-d-arabinofuranosylcytosine and increase of incubation temperature from 37 degrees c to 39.5 degrees c. infectious hsv-2 production was activated by altering incubation temperature or by superinfecting with human cytomegalovirus. we now report the establishment of an analogous system utilizing hsv type 1 (h ...19816273875

the development and use of microcarrier and glass sphere culture techniques for the production of herpes simplex viruses.two high productivity monolayer culture methods, the microcarrier and glass sphere culture, were compared for their capacity to support the growth of mrc-5 and vero cells, and herpes simplex type 2 virus. cell growth was similar in both systems giving yields of 14 x 10(5)/cm2 in microcarrier and 18 x 10(5)/cm2 in glass sphere cultures with yields of vero cells being marginally better than mrc-5 cells. virus yields were only slightly lower in these cultures than in small scale stationary cultures ...19816281104
herpes simplex vaccine using cell membrane associated antigen in an animal model.vesicles of plasma membrane, containing no detectable live virus, were prepared by treatment of herpes simplex virus type 2 (hsv-2) infected vero cells with dithiothreitol and formaldehyde. these preparations proved to be antigenic on injection into guinea-pigs and also protected these animals against intravaginal challenge with hsv-2.19816281105
expression of herpes simplex virus common surface antigens and malignancy by clonal cells of a herpes simplex virus type 2-transformed line.herpes simplex virus (hsv) type common surface antigens (csa) were examined by indirect immunofluorescence with rabbit antiserum to hsv type 1 in a clonal hamster cell line 155-4 transformed by hsv type 2. the tumor formation was examined in hamsters transplanted with various transformed and tumor cells. the examination of subclones derived from 1554-cell line gave the following results. (1) thirty subclones were isolated and classified into three phenotypes as to csa expression: (i) in csa-pos ...19816281115
antiherpes activity of [e]-5-(1-propenyl)-2'-deoxyuridine and 5-(1-propenyl)-1-beta-d-arabinofuranosyluracil.5-(1-propenyl)-1-beta-d-arabinofuranosyluracil has been synthesized, and this compound and [e]-5-(-propenyl)-2'-deoxyuridine have been tested for inhibition of herpes virus multiplication. only [e]-5-(1-propenyl)-2'-deoxyuridine was found to be an active inhibitor reducing by 50% the plaque formation of herpes simplex virus type 1 (hsv-1) at about 1 mum. a comparison to the bromovinyl derivatives showed the following order of descending activity; [e]-5-(2-bromovinyl)-2'-deoxyuridine greater than ...19816280606
a comparison of phosphonoacetic acid and phosphonoformic acid activity in genital herpes simplex virus type 1 and type 2 infections of mice.the activity of phosphonoacetic acid (paa) and phosphonoformic acid (pfa) against four strains of herpes simplex virus type 1 (hsv-1) and four strains of hsv-2 were compared in tissue culture and in a murine model of genital herpes. in mouse embryo fibroblast cells, both drugs were three-fold more active against the hsv-1 strains than against the hsv-2 strains. in contrast, in the animal model infections, paa appeared to be more active against the hsv-2 strains, while pfa was equally effective a ...19816280607
roles of polyamines in the replication of animal viruses.several animal viruses are known to contain significant amounts of polyamines but so far the function of these viral components is poorly understood. in this study the role of polyamines in the replication of two different types of viruses, herpes simplex virus type 2 and semliki forest virus (sfv) has been investigated. purified sfv was found to contain fairly small amounts of polyamines, sufficient to neutralize only about 3% of viral nucleic acid phosphate, i.e., 1/20 of that found in herpes ...19816279979
[use of a contraceptive suppository as chemoprophylaxis against sexually-transmitted diseases].the incidence of sexually transmitted diseases (std), especially gonorrhea, has risen dramatically in the past 2 decades. the population at greatest risk is also at high risk for unwanted pregnancies. since currently employed treatment methods are failing to curb the problem, a search was instituted for an available vaginal contraceptive that would have a prophylactic effect against these diseases. in vitro studies have indicated that a vaginal contraceptive made of phenylmercuric acetate is ...19816277015
sexually transmitted infections and cervical atypia.epidemiologic studies have long associated cervical cancer and dysplasia with sexual activity. in the past two decades an abundance of biological and epidemiologic data have indicated a relationship between herpes simplex virus type 2 (hsv-2) and these conditions. unfortunately, the strength of the evidence (albeit circumstantial) has led many researchers to focus exclusively on the putative role of hsv-2 as the carcinogen. at the same time, many studies have shown that cervical atypia, if it is ...19816277023
[new antigen induced by herpes simplex virus in human tumors].the study showed the new antigen induced by herpes simplex virus type 2 (hsv-2) to be present not only in cancer tumors of the cervix and corpus uteri, and ovaries but also in malignant tumors of the mammary glands, kidneys, urinary bladder, as well as in tissues of fibrous-cystic mastopathy and fibroadenoma of the mammary glands. in malignant tumors of the cervix, however, the hsv-2-induced antigen was found more frequently and had a higher serological activity than in other tumors. in contrast ...19816278776
[malignant transformation of newborn hamster cells by herpes simplex virus type 2].the oncogenic potentials of hsv-2 inactivated by ultraviolet rays in newborn hamster cell culture were studied. virus-induced morphological and malignant transformation of cells was accompanied by synthesis of virus-specific antigen, changes in morphology, formation of colonies in semi-liquid agar, and tumorigenicity of cells. the animals bearing tumors induced by transformed cells showed humoral and cellular immune responses to the virus-specific antigen. lines of transformed and tumor cells we ...19816278782

herpesvirus type 2 in adenocarcinoma of the uterine cervix: a possible association.sera from 16 jewish patients with histologically confirmed adenocarcinoma of the uterine cervix (auc) and 32 control subjects matched by age and ethnic origin were examined for herpesvirus type 1 (hsv-1) and type 2 (hsv-2) neutralizing antibodies. titers were determined by means of the quantitative plaque reduction neutralization test on vero cell monolayers, using hsv-1 strain vr3 and hsv-2 strain. significantly increased levels of antibodies against both virus strains were found in the auc pat ...19817284955
in-vivo modulation of macrophage functions by herpes simplex virus type 2 in resistant and sensitive inbred mouse strains.intra-peritoneal (i.p.) infection of mice with herpes simplex virus type 2 (hsv 2) attracted macrophages into the peritoneum. macrophages from moderately and highly hsv 2 resistant mouse strains expressed elevated phagocytosis activity 24 hours after injection. stimulation of phagocytosis in low resistant strains was generally less effective or absent. this was, in some experiments, due to the fact that macrophages were already highly activated before the experimental infection. i.p. infection a ...19817319542
tumorigenicity of herpesvirus-transformed cells correlates with production of plasminogen activator.our studies first demonstrated that established hamster cell lines transformed in vitro by herpesviruses activate plasminogen more effectively than normal hamster fibroblasts. this ability is probably due to increased levels of the enzyme plasminogen activator (pa). in the studies described here, the 333-8-9 cell line, originally transformed by herpes simplex virus type 2 strain 333, was used to derive subclonal lines that maintained stable pa phenotypes over the course of long in vitro passage. ...19816100964
herpes simplex virus types 1 and 2 and multiple sclerosis.a hypothesis is proposed which states that multiple sclerosis (ms) is caused by herpes simplex virus type 2 (hsv-2) in persons lacking herpes simplex virus type 1(hsv-1) immunity. it is examined by comparing the epidemiology of these viruses with that of ms. the age at which hsv-2 infections are first detected, as well as the age of peak incidence are similar to those for ms. if age-specific hsv-1 immunity data from various places is compared, an inverse relationship of immunity levels with lati ...19816116906
correlation of the chemical structure of 4-nitroquinolines inactivating human cytomegalovirus and established in vivo carcinogenicity tests.inactivation of the infectivity of human cytomegalovirus (cmv) and herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) has been observed following exposure to 4-nitroquinoline 1-oxide (nqo) or its metabolite, 4-hydroxyaminoquinoline 1-oxide (haqo). the present study of the specificity of the chemical structure of 4-nitroquinolines demonstrated that both the 4-nitro and 1-oxide groups were required for inactivation of virus infectivity. reduction of the 4-nitro group to a 4-hydroxyamino group ...19806119808
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, ...19806154151
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 ...19806154671
