ebv-related cytotoxicity of fc receptor negative t lymphocytes separated from the blood of infectious mononucleosis patients.epstein-barr virus (ebv) related specific killing was demonstrated previously in the t cell enriched subpopulations of blood lymphocytes of im patients. in the present work we demonstrate that the cytotoxic cells belong to the fc negative t subset. t cells in the blood of im patients can be divided in 2 categories, 1 fc positive with non discriminative cytotoxicity and the other, fc negative with selective cytotoxicity against ebv genome carrying lymphoblastoid cell lines.1978206347
detection of the ebv-determined nuclear antigen (ebna) in burkitt's lymphoma and nasopharyngeal carcinoma biopsies by the acid fixed nuclear binding (afnb) technique.epstein-barr virus (ebv) carrying biopsies of burkitt lymphoma (bl) and nasopharyngeal carcinoma (npc) were used to examine the question whether the ebv-associated nuclear antigen (ebna) can be demonstrated by the acid fixed nuclear binding (afnb) technique, developed previously for the demonstration of ebna in cultured cell lines [11]. extracts of 5 bl and 5 npc biopsies gave a brilliant, ebna specific fluorescence after binding to acid fixed chicken red cells. similar extracts of 3 other afric ...1978206349

athymic nude mice: induction of tumors containing epstein-barr virus using burkitt's-related cell lines.we studied tumor induction in athymic nude mice by d98/hr-1 cells, an epithelial somatic cell hybrid containing the epstein-barr virus (ebv) genome, and by the parental d98 and hr-1 cells. groups of animals were inoculated with cells grown in culture, with cells from tumors induced by the cell lines, or with cells from lines derived from tumors. the tumors induced by d98/hr-1 cells were undifferentiated carcinomas; those induced by d98 cells were carcinomas and those induced by hr-1 cells were p ...1978206453
lymphocytes transformed by epstein-barr virus. induction of nuclear antigen reactive with antibody in rheumatoid arthritis.sera from approximately two-thirds of patients with rheumatoid arthritis contain an antibody which is reactive with a nuclear antigen present in human b-lymphocyte tissue culture cells. the immunological reaction can be demonstrated by precipitation and immunofluorescence. evidence is present that the reactive nuclear antigen is associated with epstein-barr (eb) virus-transformed lymphocytes. normal human peripheral blood lymphocytes did not contain the nuclear antigen reactive with rheumatoid a ...1978206643
sensitization of lymphocytes against pooled allogeneic cells. i. generation of cytotoxicity against autologous human lymphoblastoid cell lines.lymphocytes sensitized in vitro to a pool of x-irradiated allogeneic normal lymphocytes from 20 individuals develop cytotoxic activity for autologous human lymphoblastoid cells (lcl). whereas pool sensitized t lymphocytes lyse autologous lcl cells, they fail to lyse autologous b-enriched or t-enriched normal target cells nor autologous phytohemagglutinin (pha) blasts. in contrast to pool sensitization, stimulation with normal cells of single allogeneic individuals rarely led to development of cy ...1978206649

epstein-barr virus-associated thymidine kinase.superinfection of raji cells with epstein-barr virus induced a new thymidine kinase that was distinguishable from both adult and fetal kinases of the host cell by discontinuous electrophoresis on polyacrylamide gels and glycerol gradients.1978206728
establishment of paired tumor cells and autologous virus-transformed cell lines to define humoral immune responses in melanoma and sarcoma patients.peripheral blood lymphocytes and skin fibroblasts from 12 cancer patients were infected with epstein-barr virus (ebv) or sv40 virus. the ebv-transformed lymphoblasts and sv40-transformed fibroblasts were grown as continuous cell lines and expressed the same histocompatibility antigens as tumor cell lines established from the same cancer patients. sera from 350 melanoma and 195 sarcoma patients were tested for antibody reactive with membrane antigens on three of these tumor cell lines (two melano ...1978204583
autoradiographic detection of epstein-barr virus (ebv)-associated early antigen in a variety of ebv dna-containing lymphoblastoid cell lines previously designated as nonproducers.by using autoradiography combined with 125i-labeled igg prepared from human sera containing high anti-ea (early antigen) antibody titers, ea has been detected in a low fraction of cells in a variety of ebv dna-containing cell lines previously designated as negative for this antigen. these positive cell lines are highly inducible for ea following treatment with iododeoxyuridine (iudr) and also contain multiple copies of the virus genome on average. the correlation between iudr inducibility and sp ...1978204604
partial purification and properties of the epstein-barr virus-associated nuclear antigen.the epstein-barr virus (ebv)-associated nuclear antigen (ebna) was purified 85-fold from a nuclear pellet derived from an ebv-transformed b lyphoblastoid cell line by a five-step procedure consisting of preparation of extract, heating at 80 degrees c in phosphate buffer, ammonium sulfate precipitation, preparative ultracentrifugation, and affinity chromatography on double-stranded dna-cellulose. the purified complement fixing antigen specifically blocked the anticomplement immunofluorescence ass ...1978204660
laboratory diagnosis of eb virus infection in some cases presenting as hepatitis.in 1975 and 1976, 7580 serum specimens were tested for hbsag by the passive haemagglutination test, hepanosticon. serum from 38 people gave a positive result after absorption with the absorbent provided, but the presence of hbsag could not be confirmed by other tests. tests for current infection with eb virus, namely, the presence of heterophil antibody and eb virus specific igm, were performed and were positive in 11 of the 38. in six of these the clinical picture was of hepatitis rather than i ...1978204666

[adenomegalic cytophagic sinusal histiocytosis. morphological and immunologic study of a case].the case of a 14-year-old boy of north-african origin, presenting a phagocytic sinus histiocytosis is reported. the main features of this now classical disease are illustrated: its localization to the neck, its chronicity, the fact that it is well tolerated, the pseudotumoral appearance of the adenomegaly as well as the intensive phagocytic (essentially lymphocytophagic) activity of the sinus macrophages. the bringing to light in a picture of hyperimmunity of an elevated percentage of antibodies ...1978205185
factors affecting serum iga antibody to epstein-barr viral capsid antigens in nasopharyngeal carcinoma.irrespective of the ethnic origin of the patient, nasopharyngeal carcinoma (npc), appears to stimulate the production of iga antibodies against vca. these antibodies are detected at high frequency and titres in sera from npc patients but only rarely from control subjects. a majority of relapse-free survivors tested 1-12 years after radiotherapy (rt) sustain a detectable level of iga anti-vca. serum titres of iga anti-vca remain relatively unchaged in individual npc patients after rt, regardless ...1978205232
an immunologic basis for detection of occult primary malignancies of the head and neck.after extensive evaluation of patients with metastatic neck disease and clinically undetectable primary cancer of the head and neck, the clinician is often faced with the difficult question of subsequent management. in this study, sera from 11 patients with clinically occult carcinoma and metastatic lymphadenopathy were studied for epstein-barr virus-associated antigens. these were compared with 35 sera from patients with known nasopharyngeal carcinoma at all stages of disease and treatment and ...1978205337
ocular granulocytic sarcoma (chloroma) with acute myelomonocytic leukemia in turkish children.in a series of 166 leukemic children from turkey, 56 had acute myelomonocytic leukemia (amml). seventeen boys and 3 girls presented with chloroma-like deposits (granulocytic or myeloid sarcomas) in the eye and orbit, all showing amml on initial study of blood and marrow. the ocular lesions responded rapidly to antileukemic therapy. laboratory studies of amml cases revealed no cytogenetic or immune defects, and epstein-barr virus titers were normal. a group-specific (gs-3) antigen (type-c virus?) ...1978205341
characterization of a unique cell line (laz 221) from human acute lymphocytic ("null" cell) leukemia.a unique human cell line designated laz 221 has been established from the peripheral blood of a patient with acute lymphocytic leukemia of the "null" cell type. the cell line does not possess the epstein-barr virus nuclear antigen and has a karyotype of 45,xx,-9,-12,+(9q12q). both the established cell line and the patient's uncultured blast cells share the same phenotypic markers. they both lack t-cell markers. they fail to form sheep erythrocyte rosettes and do not react with t-cell-specific an ...1978205365
epstein-barr virus-determined nuclear antigen in malignant epithelial cells of nasopharyngeal carcinoma.tumor tissue from lymph node metastasis of nasopharyngeal carcinoma (npc) was successfully heterotransplanted into an athymic nude mouse and the tumor grown in the nude mouse was identical in its morphology to that form the patient by optical and electron microscopy. tumor cells at passage 2 were dispersed in vitro by enzymic digestion and smeared. epstein-barr virus-determined nuclear antigen (ebna) was demonstrated in malignant epithelial cells of the smear.1978205477
[hepatology and immunology].immunologic diseases of the liver are exogenous mostly initiated by virus or endogenous initiated by autoaggression. all virus-induced kinds of hepatitis are due to an immune response against inocculated hepatocytes. therefore the hepatitis is limited to the period of complete elimination of virus-infected cells. a strong immune response therefore corresponds with an acute and short hepatitis whilest a weak immune response develops a chronic hepatitis. in contrast, autoimmune hepatitis based on ...1978205495
heterophil antigen in bovine sera detectable by immune adherence hemagglutination with infectious mononucleosis sera.bovine sera for tissue culture use were shown to contain heterophil antigen of the paul-bunnell-davidsohn type by immune adherence hemagglutination tests with sera from patients with infectious mononucleosis. the antibody titers observed were comparable to those determined by two other methods; i.e., the immune adherence hemagglutination test was found to be as specific as the differential absorption test with horse erythrocytes or the ox cell hemolysis assay,but it appeared to be the most sensi ...1978205510

state of epstein-barr virus dna in an american burkitt's lymphoma line.a human lymphoma cell line, positive for the epstein-barr virus (ebv)-associated nuclear antigen, was recently established from a north american burkitt's lymphoma. this cell line, su-amb-2, contained ebv dna both in the form of circular, nonintegrated dna molecules of viral genome length, present in multiple copies per cell, and as integrated sequences. having dna present in both of these forms, it resembled cell lines established from african burkitt's lymphomas. in studies on ebv strain diffe ...1978205666
integrated viral dna sequences in epstein-barr virus-converted human lymphoma lines.most human lymphoid cell lines contain multiple copies of circular, nonintegrated epstein-barr virus (ebv) dna molecules as well as viral dna sequences with properties of integrated dna. the physical state of the ebv dna in a human lymphoma line that only contains one virus genome equivalent per cell has now been studied by three different methods, neutral cscl density gradient centrifugation, actinomycin d-cscl gradient centrifugation, and hirt fractionation. this cell line, aw-ramos, has been ...1978205668

differences in expression of surface marker characteristics on epstein-barr virus-transformed human and simian lymphoid cell lines.human lymphoblastoid cell lines transformed in vitro by the epstein-barr virus (ebv) had receptors for fixed complement detectable by a rosette test. ebv transformed cells derived from cotton-topped marmoset leukocytes did not express this receptor. evidence is presented that both human and marmoset cell lines arose from precursor cells which have complement receptors. our findings suggest that transformation of marmoset leukocytes by ebv results in the loss of a differentiated surface marker.1978205852
characteristics of cell lines established from epstein-barr virus induced marmoset tumors.the inoculation of a cotton-topped marmoset with b95-8 strain of ebv resulted in the induction of a multifocal lymphoma and lymphoblastoid cell lines were established from liver, spleen and mesenteric lymph node tumors. the cell lines were remarkably similar to each other with respect to the presence of ebv and its expression, the surface properties of the cells and their stability, and the functional products of the cells. karyotypic examination of the cell lines revealed the common loss of a s ...1978205853
susceptibility of marmosets to epstein-barr virus-like baboon herpesviruses.epstein-barr virus (ebv)-like herpeviruses, strains of herpesvirus papio (hvp), have recently been isolated from lymphomatous (hvp-l) and from normal baboons (hvp-n). both hvp isolates infect some species of marmosets, hvp-l inoculated adult animals develop a mild to severe and sometimes fatal lymphoproliferative disease whereas newborn marmosets of the same species do not develop a measureable disease after inoculation with hvp-l. hvp-n infects adult marmosets but does not cause disease.1978205854
overview of viral oncology studies in saguinus and callithrix species.marmoset monkeys are highly susceptible to tumor induction by type c sarcoma viruses and primate lymphotropic herpeviruses. six experimental models were reviewed, three sarcoma models induced by rous, feline or simian sarcoma viruses and three models of lymphoproliferative disease induced by herpevirus saimiri, h. ateles or epstein-barr virus. relative susceptibility of cotton-topped (saguinus oedipus oedipus), white-lipped (s. nigricollis, s. fuscicollis subspecies) and commone (callithrix jacc ...1978205860
transforming activity of epstein-barr virus obtained by superinfection of raji cells.epstein-barr virus obtained by superinfection of raji cells with epstein-barr virus recovered from p3hr1 cells (hri virus) transformed human lymphocytes, but it did not superinfect raji cells. a human lymphoblastoid cell line, hlb, established by such transformation contained 22 epstein-barr virus genomes per cell and epstein-barr virus-associated nuclear antigen, and a few cells contained early or viral capsid antigen complexes. chromosomal analysis revealed that hlb-cells were diploid with nor ...1978205877

induction of ebna precedes the first cellular s-phase after ebv-infection of human lymphocytes.using a combination of immunofluorescence and autoradiography, we studied the appearance of ebna and dna synthesis in cord-blood lymphocytes after infection with ebv derived from the b95-8 cell line. ebna appeared between 12 and 25 h after addition of the virus. dna synthesis was detected in ebna-positive cells approximately 20 h after the appearance of ebna. this shows that ebna induction precedes the first cellular s-phase and suggests that the cells have not yet entered the cell-division cycl ...1978203544
two e-rosette-forming lymphoid cell lines.two e-rosette (spontaneous rosette with sheep red blood cells)-forming lymphoid cell lines were established. one (hpb-all) was derived from a young male japanese patient with acute lymphoblastic leukemia (all), and the other (hpb-mlt) was from a 62-year-old female japanese patient with a leukemic t-lymphoid malignancy. formation of e rosettes, absence of any immunoglobulin determinants, absence of ebna (epstein-barr virus associated nuclear antigen) and very limited stimulating ability in mixed ...1978203546
immune function in healthy relatives of patients with malignant disease.immune function studies of healthy members of families with multiple lymphoreticular neoplasms were compared with those of healthy members of families with multiple cancers and families with no known history of cancer. the lymphoma family group had a significantly elevated serum level of igm and diminished responses to the candida albicans skin test antigen and the t-cell mitogen concanavalin a. subjects with epstein-barr virus-viral capsid antigen titers greater than or equal to 160 had lower r ...1978203705
epstein-barr virus-associated and other antiviral antibodies during intense bcg administration to patients with burkitt's lymphoma in remission.patients with burkitt's lymphoma in chemotherapy-induced remission received through dermal scarifications one or two doses per week of approximately 3 x 10(8) living bcg organisms (pasteur institute vaccine). this treatment was always followed by usually rapid increases by 1--4 log2 steps in the antibody titers to epstein-barr virus (ebv)-associated cell membrane antigens. titer increases of less than 2.5 log2 steps within the first month after the start of bcg treatment correlated with a signif ...1978203706
infectious mononucleosis and the epstein-barr virus.recent elucidation of the relationship between the epstein-barr virus and infectious mononucleosis has resulted in the development of new diagnostic serological tests, and has amplified our knowledge of the epidemiological and clinical aspects of the disease. the history, epidemiology, clinical characteristics, diagnostic features, and therapy of infectious mononucleosis are reviewed. this is done in the light of recent knowledge concerning the epstein-barr virus as well as previous studies empl ...1978203184
tonsillectomy and infectious mononucleosis.tonsillar tissue may be the primary site of infection with epstein-barr virus (ebv), the etiologic agent of classical infectious mononucleosis (im). therefore, a retrospective study of the association between tonsillectomy and im was performed in a college student population. in the first part of the study, tonsillectomy rates were compared between 164 im-positive students and 164 student controls who attended ucla in 1972-1975. although it was determined that the development of im during colleg ...1978203187
large-scale production and concentration of infectious epstein-barr virus.infectious epstein-barr virus (ebv) was produced from suspension cultures of p3hr-1 cells. a protocol for the scaled-up production and concentration of the virus was developed. virus from the culture fluid was concentrated by continuous-flow pelletization or continuous flow with banding in sucrose. ebv prepared by pelletization yielded 1.7 x 10(4) infectious units/ml (100 x concentration) and less than 3.4 x 10(7) evb particles/ml (1,000 x concentration), whereas ebv prepared by banding yielded ...1978203227
a new lymphoid cell line, reh 6, with characteristics of non-t and non-b cells, lacking the epstein-barr virus genome and derived from human acute lymphoblastic leukemia.a new lymphoid cell line, reh 6, has been established from the peripheral blood of a patient with acute lymphocytic leukemia. reh 6 cells were assayed for the presence of epstein-barr virus (ebv) dna by nucleic acid hybridization and for epstein-barr nuclear antigen (ebna) by the immunofluorescence test. reassociation kinetics between in vitro [3h]-labeled ebv dna and reh 6 cell dna indicated the absence of detectable amounts of ebv dna in reh 6 cell dna. in addition, attempts to detect ebna by ...1978202576
appearance of early and late components of epstein-barr virus-associated membrane antigen in daudi cells superinfected with p3hr-1 virus.this study investigated the synthesis of membrane antigen (ma) as well as virus capsid antigen (vca) and early antigen (ea) in daudi cells which had been superinfected with the p3hr-1 strain of epstein-barr virus (ebv) and then treated with trypsin to remove initially absorbed ma-positive material from the cell surface. synthesis of ma, vca and ea was completely inhibited by puromycin. a marked reduction in the frequency of ma positive cells was observed in superinfected cells cultured in the pr ...1978202665
cytofluorometry of lymphocytes infected with epstein-barr virus: effect of phosphonoacetic acid on nucleic acid.dna synthesis in epstein-barr virus (ebv)-infected lymphocytes was inhibited by phosphonoacetic acid (paa) as measured by [3h]thymidine incorporation. paa, at a concentration of 200 microgram/ml, inhibited [3h]thymidine incorporation by human umbilical cord lymphocytes infected with ebv strain p94 but had little effect on dna synthesis in mitogen-stimulated cells. transformed cell lines did not develop from infected cord cell cultures treated with 100 microgram of paa per ml. cytofluorometric an ...1978202732
radiobiological inactivation of epstein-barr virus.lymphocyte transforming properties of b95-8 strain epstein-barr virus (ebv) are very sensitive to inactivation by either uv or x irradiation. no dose of irradiation increases the transforming capacity of ebv. the x-ray dose needed for inactivation of ebv transformation (dose that results in 37% survival, 60,000 rads) is similar to the dose required for inactivation of plaque formation by herpes simplex virus type 1 (fischer strain). although herpes simplex virus is more sensitive than ebv to uv ...1978202757

comparison of the stimulating capacity of human leukemia t-cell, null cell, and b-cell lines in mixed lymphoma culture.one-way mixed lymphocyte reactions between lymphocytes from normal human donors and mitomycin c-treated cells from human leukemia t-cell, null cell, and b-cell lines were investigated. an epstein-barr virus (ebv)-negative japanese burkitt's lymphoma line and two ebv-positive normal lymphoid cell lines were studied in parallei. normal lymphocytes were stimulated significantly by the cultured null cells and b-cells, but only slightly by the cultured t-cells. the stimulatory capacity of these two l ...1978147348
the simultaneous observations of immunofluorescence and cellular morphology in viral infections: a new procedure.a simple method for comparative observations of immunofluorescence and cellular morphology has been developed in the investigation of epstein-barr virus (ebv) infection and oncogenesis. when cells were stained for immunofluorescence of ebv-determined nuclear antigen, early antigens, or the viral capsid antigen, followed by treatment with hematoxylin, viral marker expression and cellular morphology could be simultaneously observed in individual cells by simply changing ultraviolet illumination to ...197895789
a novel surface antigen on lymphoid cells transformed by epstein-barr virus.a surface antigen (sa) was detected on ebv-carrying lymphoid cell lines by an indirect membrane immunofluorescence test with serum from rabbits immunized with raji cells; the antiserum had been extensively absorbed with normal human blood and tonsil cells. the sa was not detected on normal human umbilical-cord and adult peripheral blood lymphocytes or ebv-negative cell lines. the incidences of the sa and ebv-determined membrane antigen (ma) on certain ebv-carrying cell lines were not compatible. ...197887368

uv-inactivation of epstein-barr virus: differences in early antigen expression in two different non-productive cell lines and influence of caffeine.two non-productive epstein-barr (eb) virus genome-carrying lymphoblastoid cell lines, namely raji and nc37, were used for studying the effect of uv irradiation on the ability of p3hr-1 eb virus to induce early antigen (ea) formation. in nc37 cells infected with uv-irradiated virus the formation of ea was delayed; thus the slope of inactivation curve based on the early (24 hr) reading was steeper than that based on the late (72 hr) reading. this was not observed in raji cells. caffeine did not in ...197830263

production of rabbit antibodies against the viral capsid antigen (vca) of the epstein-barr virus (ebv).rabbits were immunized with nuclear or cytoplasmic extracts of the epstein-barr virus (ebv)-producing marmoset cell line b95-8. following extensive absorption with human ebv-negative cells (hep-2, ramos and bjab), sera were obtained that no longer reacted with cellular or serum proteins of human origin, but gave a single precipitin band with extracts of the human ebv-producing line, p3hr-1. immunofluorescence tests performed with appropriate parallel human serum controls showed that the rabbit s ...197875856
transmission of non-a, non-b hepatitis from man to chimpanzee.non-a, non-b hepatitis was transmitted to four colony-born chimpanzees by intravenous inoculation of human sera. two chimpanzees were inoculated with serum from a patient with a clinical and serological diagnosis of chronic non-a, non-b hepatitis whose blood appeared to transmit this disease to a nurse following accidental needle-stick, and the other two chimpanzees were inoculated with serum from either of two former blood-donors whose hbsag-negative blood appeared to transmit clinically recogn ...197876018

observations on cell lines derived from a patient with hodgkin's disease.permanent cell lines have been established from a spleen nodule and lymph node of a male hodgkin's disease (hd) patient whose father has the same disease. th in vitro growth pattern morphological and cytogenetic characteristics of these lines maintained continuously for over 2 years are described. the cultures contain a population of mixed cell types that grow in suspension. between 5 and 10% of the cells have surface immunoglobulins m and d. b-cell alloantigens are also detectable. while the cu ...197878764
colonies of ebna-positive cells in soft agar from peripheral leukocytes of infectious mononucleosis patients.epstein-barr virus (ebv)-associated nuclear antigen (ebna)-positive lymphoblastoid cells grew as colonies in soft agar after seeding of leukocytes from the peripheral blood of four patients with infectious mononucleosis serologically determined to be caused by ebv. in individual cases more colonies were obtained from blood specimens during the acute phase of the disease than during the convalescent phase. incorporation of human umbilical cord serum, which contained neutralizing antibody to ebv, ...197878908
ebv antigens in lymphocytes of patients with exudative tonsillitis, infectious mononucleosis and hodgkin's disease.a protocol utilizing isokinetic gradients to isolate human lymphocytes is combined with another that purifies the c3 receptor-bearing b lymphocyte subpopulation, thus enriching the eb virus genome-carrying population. also, rabbit antisera were prepared to the epstein-bar virus nuclear antigen (ebna) and the early antigen (ea) and utilized in an indirect immunofluorescence test (iit) to detect these antigens in human lymphocytes isolated from various disease states. using these methods we demons ...197878913
persistent epstein-barr virus infection in a child with hypergammaglobulinaemia and immunoblastic proliferation associated with a selective defect in immune interferon secretion.a 5-year-old girl had a chronic disease characterised by fever, lymphoid hyperplasia, interstitial pneumonitis, thrombocytopenia, and polyclonal hypergammaglobulinaemia. evidence for severe, persistent epstein-barr virus (e.b.v.) infection was found: titres of antibody to e.b.v. viral capsid antigen (igm and igg) and early antigen were extremely high, cells containing e.b.v.-associated nuclear antigen (e.b.n.a.) were found in lymph nodes and blood, and spontaneous permanent lymphoblastoid cell l ...197879029
