| amplification and characterization of herpesvirus dna in cerebrospinal fluid from patients with acute encephalitis. | a single pair of oligonucleotide primers selected within a highly conserved region of the dna polymerase gene of the herpesviruses was designed to amplify related viral genomes, i.e., herpes simplex virus type 1, herpes simplex virus type 2, epstein-barr virus, and cytomegalovirus, by the polymerase chain reaction. a simple restriction enzyme analysis of these amplified products allowed accurate characterization of the herpesvirus type. ninety-nine cerebrospinal fluid samples from 36 patients (i ... | 1991 | 1663508 |
| genomic sequences homologous to the protein kinase region of the bifunctional herpes simplex virus type 2 protein icp10. | the large subunit of herpes simplex virus type 2 (hsv-2) ribonucleotide reductase (icp10) consists of two functional domains. the amino (n)-terminal domain at residues 1-411 has serine/threonine-specific kinase activity (pk domain) and is encoded by a dna fragment with transforming potential (15,17). the remaining region is required for ribonucleotide reductase activity (rr domain) (14, 15). computer-assisted comparison of the icp10 sequence to the embl database 21 has revealed sequences within ... | 1991 | 1663292 |
| discrimination of herpes simplex virus types 1 and 2 cerebral infections in a rat model. | a rat model was used to evaluate intertypic differences after intracranial (i.c.) inoculation of herpes simplex virus (hsv) types 1 and 2 strains with regard to neurovirulence and neuropathology, and influence of age on susceptibility. in adult rats, hsv-1 strains were more virulent than hsv-2 strains. hsv-1 replicated to higher titers in the central nervous system (cns) of rats, as compared with hsv-2. in rats of less than 2-3 weeks of age, hsv-1 and hsv-2 were equally virulent, but morphologic ... | 1991 | 1662855 |
| a transformation-specific polypeptide distinct from heat shock proteins is induced by herpes simplex virus type 2 infection. | a tumour-specific polypeptide designated u90 is one of a set of polypeptides which are encoded by the host cell and are specific for the transformed cell state, being immunoprecipitated by the sera of tumour-bearing animals. the interest in these tumour-specific polypeptides centres on the finding that they are also recognized by antisera raised against herpes simplex virus type 2 (hsv-2)-infected cells, implying some role for hsv-2 in tumorigenesis. the peptide map of hsv-2-induced u90 is indis ... | 1991 | 1662699 |
| comparative sequence analysis of the long repeat regions and adjoining parts of the long unique regions in the genomes of herpes simplex viruses types 1 and 2. | we report the determination of the dna sequence of the long repeat (rl) region and adjacent parts of the long unique (ul) region in the genome of herpes simplex virus type 2 (hsv-2) strain hg52. the dna sequences and genetic content of the extremities of hsv-2 ul were found to be closely similar to those determined previously for hsv-1. the 5658 bp sequenced at the left end of hsv-2 ul contained coding regions for genes ul1 to ul4 plus part of ul5. the 4355 bp sequenced at the right end of ul co ... | 1991 | 1662697 |
| efficacy of hsv-1 iscom vaccine in the guinea-pig model of hsv-2 infection. | the capability of a herpes simplex virus (hsv)-1 iscom vaccine to protect against intravaginal hsv-2 challenge infection in guinea-pigs is described. the protective efficacy of the hsv-1 iscom vaccine is compared with that of a purified, aqueous hsv-1 antigen preparation administered using a similar immunization schedule. the results show that female guinea-pigs immunized with two doses of hsv-1 iscom vaccine, each consisting of 20 micrograms of protein given 2 weeks apart responded with high el ... | 1991 | 1661978 |
| improved detection of hsv by electron microscopy in clinical specimens using ultracentrifugation and colloidal gold immunoelectron microscopy: comparison with viral culture and cytodiagnosis. | three tests were compared to diagnose herpes virus infection: electron microscopy (em), viral culture (vc) and cytodiagnosis (tzanck smear). the study comprised 67 patients with skin or mucous membrane lesions suggestive of herpes simplex virus (hsv) infection. the sensitivity of em increased 25% after virus concentration by ultracentrifugation. herpes virus infection was confirmed in 55 of the 67 cases by em or vc or both. em detected 53 herpes virus-positive lesion samples of which 14 were not ... | 1991 | 1660490 |
| apical expression of herpes simplex virus type 2 glycoproteins in human neuroblastoma cells. | the expression of herpes simplex virus type 2 (hsv-2) glycoproteins on the surface of human neuroblastoma cells has been investigated using millipore millicell culture plate inserts. utilizing a modified radioimmunoassay, we learned that glycoproteins b, c, d, e, and i were expressed predominantly on the apical membrane domain of the infected neuroblastoma cells. the unidirectional transport of hsv-2 glycoproteins was substantiated by the analysis of extracellular glycoproteins released from neu ... | 1991 | 1660208 |
| antiviral activity of 1-docosanol, an inhibitor of lipid-enveloped viruses including herpes simplex. | this article reports that 1-docosanol, a 22-carbon-long saturated alcohol, exerts a substantial inhibitory effect on replication of certain viruses (e.g., herpes simplex virus and respiratory syncytial virus) within primary target cells in vitro. to study the basis for its viral inhibitory activity, a suspension of 1-docosanol was formulated in an inert and nontoxic surfactant, pluronic f-68; this suspension exerted potent inhibitory activity on the ability of susceptible viruses to infect cultu ... | 1991 | 1660151 |
| suppression of immune responses by herpes virus type 2-transformed murine tumor cells. | work done in our laboratories, using a murine model, indicates that suppression of host immune responses might be due to secretion of soluble factors by tumor cells. the h238 cells (balb/c embryonic fibroblasts transformed by uv-inactivated herpes simplex virus type 2) exhibit progressive tumor growth with subsequent decrease in lymphoproliferation. to further study the suppressive effects of a tumor, h238 conditioned medium (cm) was tested for its ability to block murine and human mitogenic and ... | 1991 | 1660030 |
| recurrent herpes simplex virus type 2 encephalitis in a preterm neonate. favourable outcome after prolonged acyclovir treatment. | we describe a case of recurrent herpes simplex virus type 2 (hsv-2) central nervous system infection in a preterm neonate. on two occasions, encephalitis occurred together with eruption of vesicles on the right arm, and the patient was treated with acyclovir. new recurrences of vesicles followed each attempt to discontinue antiviral treatment, and prompted a continuous long-term acyclovir prophylaxis. at three years of age, the patient has developed normally. the use of immunoblotting for serolo ... | 1991 | 1659768 |
| evaluation of a test based on baculovirus-expressed glycoprotein g for detection of herpes simplex virus type-specific antibodies. | an immunoblot assay for discrimination of antibodies to herpes simplex virus (hsv) types 1 and 2 was devised using extracts of recombinant-baculovirus-infected insect cells expressing hsv-1 or -2 glycoprotein g (gg1 or gg2). the assay was evaluated by comparing its results with those obtained by using an immunodot assay based on gg immunopurified from hsv-1- and hsv-2-infected cells. each of 110 human serum specimens was tested blindly and independently three times. at a serum dilution of 1:20, ... | 1991 | 1659601 |
| the pathogenicity of ribonucleotide reductase-null mutants of herpes simplex virus type 1 in mice. | the pathogenicity of ribonucleotide reductase (rr)-null mutants (hrr3 and icp6 delta) of herpes simplex virus (hsv) type 1 was studied after intracerebral and corneal inoculation in newborn and adult icr mice. icp6 delta failed to replicate in brains of mice greater than or equal to 8 days old but exhibited significant virulence for newborn mice as a result of viral replication in the brains. the rr- and a thymidine kinase (tk)-deficient mutant of hsv-1 strain kos could grow in eye tissues of ad ... | 1991 | 1659596 |
| development and evaluation of an elisa using secreted recombinant glycoprotein b for determination of igg antibody to herpes simplex virus. | an elisa for the determination of igg antibody to herpes simplex virus (hsv) was developed using a secreted recombinant hsv-1 glycoprotein b (gb-1s) as a solid phase. the clinical validity of the elisa was established by testing different groups of sera containing hsv-1, hsv-2, or mixed antibody, in parallel with gb-1s elisa and conventional hsv-1/hsv-2 elisa. the new gb-1s elisa detected hsv-1/hsv-2 antibody in sera from 48 subjects with either hsv-1 or hsv-2 past infection as well as in sera f ... | 1991 | 1659581 |
| effects of cytokines and r-837, a cytokine inducer, on uv-irradiation augmented recurrent genital herpes in guinea pigs. | we have recently reported that latently hsv-2-infected guinea pigs exhibit a three- to four-fold increase in recurrent lesions after exposure to ultraviolet radiation (uv), allowing rapid evaluation of antiviral drugs in treating recurrent hsv disease. in this report we examine the effect of alpha interferon (ifn-alpha), interleukin-2 (il-2), and a cytokine inducer (r-837) on uv-induced recurrent genital herpes. we have previously shown that topical r-837 is a biologic response modifier with no ... | 1991 | 1659313 |
| sequence, function, and regulation of the vmw65 gene of herpes simplex virus type 2. | we determined the sequence of the gene for the virion transactivator protein vmw65 of herpes simplex virus type 2 (hsv-2), strain 333. an analysis of the coding sequence revealed an overall high degree of primary sequence conservation (86%) relative to the hsv-1 protein, although the carboxy-terminal region which encompasses the powerful acidic transactivation domain of the hsv-1 protein was slightly less well conserved (70%). one important change in this region was the presence of a proline res ... | 1991 | 1658370 |
| abolition of the rl neurovirulence phenotype of herpes simplex virus type 2 strain hg52 does not require deletion of the dr1 element of the 'a' sequence. | we have characterized a spontaneous variant of herpes simplex virus type 2 (hsv-2) strain hg52, 2616, which has 786 bp of both copies of rl deleted, but which retains 782 bp upstream of the 5' end of immediate early gene 1 and 463 bp downstream of the 'a' sequence. variant 2616 is avirulent following intracerebral inoculation of balb/c mice, thus showing in vivo characteristics similar to those of variant 2604, described previously (a 1488 bp deletion incorporating the dr1 element of the 'a' seq ... | 1991 | 1658204 |

| the herpes simplex virus 1 protein kinase encoded by the us3 gene mediates posttranslational modification of the phosphoprotein encoded by the ul34 gene. | earlier studies have shown that a herpes simplex virus 1 (hsv-1) open reading frame, us3, encodes a novel protein kinase and have characterized the cognate amino acid sequence which is phosphorylated by this enzyme. this report identifies an apparently essential viral phosphoprotein whose posttranslational processing involves the viral protein kinase. analyses of viral proteins phosphorylated in the course of productive infection revealed a phosphoprotein whose mobility was viral protein kinase ... | 1991 | 1656069 |
| herpes simplex virus type 2: a possible interaction with human papillomavirus types 16/18 in the development of invasive cervical cancer. | a case-control study of 766 histologically confirmed incident cases of invasive cervical cancer and 1,532 hospital and community controls was conducted in latin america to evaluate the etiologic role of herpes simplex virus type 2 (hsv-2) and to examine whether hsv-2 interacts with other risk factors. in addition to a personal interview, all subjects were asked to donate blood samples and cervical swabs for assessment of exposure to hsv-2 and human papillomaviruses (hpvs) respectively. ninety-ei ... | 1991 | 1655658 |
| genital warts, other sexually transmitted diseases, and vulvar cancer. | to determine whether specific sexually transmitted diseases were associated with an increased risk of vulvar cancer, we conducted a case-control study among residents of three countries in western washington. we identified, interviewed, and obtained blood samples from women with in situ (n = 180) and invasive (n = 53) vulvar cancer, 18-79 years of age, who were first diagnosed with these diseases during 1980-1988. we compared their responses with those of 466 women from the general population wh ... | 1991 | 1655066 |
| screening pregnant women for genital herpes. | in a prospective study to identify the viral type isolated from women undergoing screening for herpes simplex virus (hsv) during pregnancy using fluoroscine-labelled monoclonal antibodies to hsv-1 and hsv-2, hsv-2 was more likely to be isolated during the third trimester and was the only viral type isolated at term. as the severity of neonatal central nervous system disease is greater with hsv-2 than hsv-1 we recommended that all women with a history of genital herpes should be screened during p ... | 1991 | 1655058 |
| modulation of lymphoproliferation and oxidative burst by herpes-transformed tumors. | in this study, herpes simplex virus type 2 (hsv-2)-transformed cells (h238) and conditioned medium (cm) from h238 cell cultures were studied with respect to their effects on lymphoproliferation and the chemiluminescent oxidative burst of phagocytic cells. the h238 cells expressed a nuclear antigen detectable by fluorescent antibody testing using pooled sera from tumor-bearing mice, but no hsv-1 or hsv-2 cell membrane antigens could be found using specific monoclonal antibodies. balb/c mice subcu ... | 1991 | 1654931 |
| enhanced malignant transformation induced by expression of a distinct protein domain of ribonucleotide reductase large subunit from herpes simplex virus type 2. | the 1.3-kilobase (kb) pst i dna fragment c (pst i-c) of herpes simplex virus type 2 (hsv-2) morphological transforming region iii (mtriii; map unit 0.562-0.570) encodes part of the n-terminal half of the large subunit of ribonucleotide reductase (rr1; amino acid residues 71-502) and induces the neoplastic transformation of immortalized cell lines. to assess directly the role of these rr1 protein sequences in cell transformation, the pst i-c fragment was cloned in an expression vector (p91023) co ... | 1991 | 1654564 |
| the nucleotide sequence, 5' end, promoter domain, and kinetics of expression of the gene encoding the herpes simplex virus type 2 latency-associated transcript. | the sequence of the herpes simplex virus type 2 (hsv-2) latency-associated transcript (lat) region resembles that of hsv-1 only where the lats overlap icp0 and in the putative promoter region. otherwise, the lat 5' ends, kinetics of expression, and promoter elements are mostly conserved between hsv-1 and hsv-2. the remaining differences between the lats could contribute to each virus's distinctive pattern of reactivation. | 1991 | 1654458 |
| the rl neurovirulence locus in herpes simplex virus type 2 strain hg52 plays no role in latency. | we have demonstrated that the variant jh2604 of the herpes simplex virus type 2 (hsv-2) strain hg52 is completely avirulent in balb/c mice following intracranial inoculation, with an ld50 of greater than 10(7) p.f.u./mouse compared to the wild-type ld50 of less than 10(2) p.f.u./mouse. in jh2604, a 1.5 kbp deletion extends from the dr1/ub junction of the 'a' sequence to 511 bp upstream of the 5' end of ie1 in both long repeats. we have since constructed a second variant (2701) in which only 850 ... | 1991 | 1654382 |
| cleavage of the bovine herpesvirus glycoprotein b is not essential for its function. | herpes simplex virus glycoprotein b (hsvgb) and its bovine herpesvirus homologue (bhvgb) share similar primary structures. these glycoproteins are present in the envelope of the virion and are believed to initiate infection by fusing the virus envelope with a host cell membrane. bhvgb, like the membrane-fusing glycoproteins of most enveloped viruses, is normally cleaved and is present as a disulphide-linked complex in the virus envelope and host cell membranes. hsvgb, however, remains uncleaved, ... | 1991 | 1654372 |
| herpes simplex virus glycoprotein c is a receptor for complement component ic3b. | herpes simplex virus type 1-infected cells bind c3b and ic3b, but not c3d, at the cell surface. herpes simplex virus type 2 (hsv-2)-infected cells bind none of these c3 fragments. a transfection assay was used to demonstrate that binding of ic3b was to gc1. although ic3b did not bind to hsv-2-infected cells, it did bind to mammalian cells transfected with the gc2 gene. using linker insertion mutants, three domains on gc2 that are important for binding ic3b were mapped; these regions were similar ... | 1991 | 1654359 |
| seroreactive recombinant herpes simplex virus type 2-specific glycoprotein g. | the herpes simplex virus type 2 (hsv-2) genome codes for an envelope protein, glycoprotein g (gg), which contains predominantly type 2-specific epitopes. a portion of this gg gene has been expressed as a fusion protein in escherichia coli. expression was regulated by a lambda phage pl promoter. the 60,000-molecular-weight recombinant protein was purified by ion-exchange chromatography. amino acid sequence analysis confirmed the n terminus of the purified protein. mice immunized with recombinant ... | 1991 | 1653787 |
| nucleotide and deduced amino acid sequences of the gene encoding virion protein 16 of herpes simplex virus type 2. | a virion protein (vp16) of herpes simplex virus (hsv) activates transcription of viral immediate-early genes. we have determined the nucleotide sequence of the virion activator gene from hsv-2, which we term vp16-2. comparison of the deduced amino acid sequences of the hsv-1 and hsv-2 homologs shows that the vp16-2 gene product retains features determined to be important for transcriptional activation by vp16. | 1991 | 1653757 |
