induction of epstein-barr virus early antigens by corticosteroids: inhibition by tpa and retinoic acid.corticosteroids can induce the synthesis of ebv antigens in the burkitt lymphoma line daudi. as early as 12 h after application of the drug, an increase of ea-positive cells can be seen, the maximum induction being reached after 2 days. nanogram amounts per ml of hormone are sufficient for measurable effects. early antigen induction by corticosteroids does not require replication of viral dna. induction by corticosteroid differs from induction by other systems in two major respects: (1) it does ...19836826253
multiple hepatitis attacks with immunothrombocytopenia in a heroin addict.a 25-year-old heroin-addict had four episodes of acute hepatitis, each of them associated with thrombocytopenia. serologically, hepatitis a and b as well as cytomegalo- or epstein-barr virus infections were excluded. high levels of circulating immune complexes and antibodies reacting with aminophospholipids, a component of both liver cell and platelet membranes, were detected during the last two attacks of hepatitis, but were absent during remission. platelet-associated antibodies of the igm cla ...19836832695
detection of hla antigens on lymphoblastoid and epithelial cell lines and cross-reactivity of hla-cw5 and hla-cw8.antibody-dependent cell-mediated cytotoxicity was used to detect hla antigens on tissue cultured lymphoblastoid cells (phytohemagglutin blasts and epstein-barr virus lines) and transitional cell carcinomas. the results agreed with those obtained on fresh peripheral blood lymphocytes by conventional hla typing. the same hla antigens were detected on cells from an individual irrespective of their tissue origin or length of time in vitro. antibody-dependent cell-mediated cytotoxicity (adcc) showed ...19836841162
inhibition of 12-o-tetradecanoylphorbol-13-acetate-induced induction in epstein-barr virus early antigen in raji cells.retinol, 5 flavonoids, 3 steroids and 7 sweetening agents were studied for their effects on 12-o-tetradecanoylphorbol-13-acetate (tpa)-induced early antigen (ea) of epstein-barr virus (ebv) in raji cells. concomitant treatment of raji cells with tpa and retinol showed inhibition of ea induction. among flavonoids, quercetin resulted in effective inhibition of ea induction by tpa and alpha-naphthoflavone showed the weakly inhibitory effect. none of the other flavonoids such as rutin, catechin and ...19836850568
o6-methylguanine removal by competent and incompetent human lymphoblastoid lines from the same male individual.two cell lines, one proficient (mex+) and one deficient (mex-) in the ability to remove o6-methylguanine, have been isolated by epstein-barr virus-mediated transformation of a single blood sample obtained from a normal human male. extracts of untreated cells differ in their o6-methylguanine transferase (methyl acceptor protein) activity. although both lines arise from the same individual, they show great difference in their sensitivities to the toxic action of n-methyl-n'-nitro-n-nitrosoguanidin ...19836850639

epstein-barr virus infection and antibody synthesis in patients with multiple sclerosis.we studied infectious and immune mechanisms in demyelinating disease. the clinical diagnosis in this study of 313 consecutive cases of multiple sclerosis (ms) was based on the clinical conclusions of two or more neurologists and definite abnormalities in csf igg. measurement of antibodies to six microbial agents was compared in 313 patients with ms and 406 controls in the same age range. using a standardized immunofluorescent antibody (ifa) technique, we found a significantly higher prevalence o ...19836860175
erythema nodosum associated with infectious mononucleosis.erythema nodosum is an immunoallergic epiphenomenon appearing during the course of various conditions; it has been exceptionally observed in association with infectious mononucleosis. a 9-year-old girl with clinical manifestations of infectious mononucleosis developed cutaneous nodules of erythema nodosum over the shins, which cleared after 12 days. diagnosis was based on the presence of atypical mononuclear cells, detection of antibodies against epstein-barr virus, and positive ox red blood cel ...19836862998
primary infection by epstein-barr virus presenting as aplastic anemia. 19836866059
viruses and human cancer.the cause of human cancer is probably multifactorial and the role of viruses is unclear. the study of retroviruses has led to the identification of oncogenes responsible for transformation and tumor induction. human viruses associated with malignancies include the jc virus (associated with progressive multifocal leukoencephalopathy) and some adenoviruses. no human malignancies have been associated with the latter group. a number of herpes viruses of lower animals have been associated with malign ...19836870184
antibody- and interferon-dependent killer cells are part of the nk cell receptor positive subpopulation of human peripheral blood cells.cytotoxicity by human non-adherent peripheral blood lymphocytes was analysed after effector cell activation with either interferon (if) or by target cell specific igg antibodies (t-igg). four different cell lines were used as target cells that differed in susceptibility to natural killer cell (nk) activity; a highly susceptible t cell line (molt-4), a medium susceptible b lymphoma line (daudi), a resistant b cell line established by epstein-barr virus transformation (lcl-ls) and a resistant mous ...19836872324
altered oligosaccharides as the initiating autoantigen in rheumatoid arthritis.the linkage of rheumatoid arthritis (ra) to infection though vague has remained a persistent notion for the past fifty years. the hypotheses that streptococcus was responsible; then m. pneumoniae; the implication of a viral pathogenesis and, more especially, the epstein-barr virus, have all not withstood the test of koch's postulates. today, autoimmunity holds the field in the pathogenesis of ra. we know in fair detail what happens after failure of self-recognition develops. why does synovial ti ...19836877115
viral antibodies in maternal and cord sera.viral antibodies were determined in paired maternal and cord blood sera of 258 consecutive deliveries. antibodies to epstein-barr virus (ebv), cytomegalovirus (cmv), herpes simplex type 1 (hsv-1), adenovirus (adv), and varicella zoster (vzv) were tested by indirect immunofluorescence and to rubella (rub) by hemagglutination inhibition. analysis of the overall pattern of differences between maternal and cord blood showed a highly significant difference for all six viruses. analysis regarding indi ...19836877173
gangliotriaosylceramide (asialo gm2), a glycosphingolipid marker for cell lines derived from patients with hodgkin's disease.three cell lines, isolated from different patients with hodgkin's disease, were analyzed for their neutral glycosphingolipids by high performance liquid chromatography. on two of these lines gangliotriaosylceramide (asialo gm2) was identified by the comparison of retention time to authentic standards and by degradation with specific glycosidases. this glycosphingolipid was also serologically detected with a specific monoclonal antibody of the igm class. the third line, which according to other c ...19836886427
characterization of lymphoid cells by two-dimensional mini gel electrophoresis of proteins.cytosol proteins from normal lymphocytes, leukemic lymphocytes, and different cultured lymphoid cell lines were separated by two-dimensional mini gel electrophoresis. by staining with coomassie blue, specific protein patterns were obtained. very similar gel maps were produced by the cytosol proteins of chronic lymphocytic leukemia cells, hairy cells, and of in vitro grown b cells. protein 36/6.2 (molecular weight/isoelectric point), consistently present in these cells, could not be demonstrated ...19836572191
[fatal infectious mononucleosis in a leukemic child in remission].the authors report the case of a 5 year-old girl who died from primary epstein-barr virus infection while in remission from acute lymphoblastic leukemia. there was a diffuse, polymorphic and polyclonal proliferation of b lymphocytes, associated with a strong histiocytic reaction with hemophagocytosis. the role of epstein-barr virus was ascertained by the appearance of specific antibodies and the finding of ebna antigen on liver smear.19836578707
characterization of the phorbol 12,13-dibutyrate (p(bu)2) induced binding between human lymphocytes.the mechanisms, cell surface structures, and cell types involved in the phorbol 12,13-dibutyrate (p(bu)2)-induced binding between human lymphocytes were studied. induction of cell aggregation by 20 min treatment with p(bu)2 required ca2+, an intact membrane, functional microfilaments, and the possible participation of an esterase or, less likely, a protease. trypsin-sensitive cell surface structures were needed and neuraminidase (nanase) treatment slightly increased the intercellular binding. re ...19836580088
human monoclonal antibody to a neuroectodermal tumor antigen (ofa-i-2).human igm kappa monoclonal antibody to human tumors of neuroectodermal origin was produced in the spent medium of an epstein-barr virus-transformed b-lymphoblastoid cell line, l72. chemically, the antigen was identified as ganglioside gd2 [gal nac beta 1----4 (neu ac alpha 2----8 neu ac alpha 2---3) gal beta 1----4 glc----ceramide]. twenty-seven mg of pure human igm were obtained from 10 liters of l72 spent medium using salt and hypotonic precipitation, ultracentrifugation, and sephacryl-s 300 s ...19836584083
pre-b-cells in normal human bone marrow and in bone marrow from patients with leukemia in remission: persistent quantitative differences and possible expression of cell surface igm in vitro.pre-b-cells are bone marrow lymphoid cells that lack surface immunoglobulin (sig-) but contain intracytoplasmic (c) igm heavy chains and are probably the immediate precursors of immature sigm+ b lymphocytes. to better understand early stages of b-cell development, immunofluorescence techniques were employed to identify pre-b-cells and b lymphocytes and to examine the expression of sigm in vitro by human marrow that had been previously depleted of b cells by immunoadsorption. marrow was derived f ...19836600632
chromosome replication in normal and transformed human lymphocytes.we analyzed the late-replication patterns of human b-lymphocyte chromosomes before and after transformation by epstein-barr virus. there were no statistically significant differences between normal cells and transformed cells derived from the same male individual; therefore, the order of termination of chromosome replication was unchanged by transformation. we also examined the replication patterns of t lymphocytes from the same donor and found no differences between normal b and t cells.19836601510
increased frequency of rheumatoid factor precursor b lymphocytes after immunization of normal adults with tetanus toxoid.vaccination of normal adults with tetanus toxoid induced a two-three-fold rise in the frequency of igm anti-igg (rheumatoid factor, rf) b lymphocytes inducible by the polyclonal b cell activator, epstein-barr virus. the increase in igm-rf precursors occurred earlier, was greater in magnitude, and was more sustained than the change in plasma igm-rf. it was associated with a rise in total igm levels, and correlated positively with the magnitude of the igg anti-tetanus antibody response, but not wi ...19836601551
deficiency in epstein-barr virus receptors on b-lymphocytes of preleukemia patients.lymphocytes from eight preleukemia patients were exposed to epstein-barr virus (ebv) in vitro in an attempt to establish lymphoblastoid cell lines. no signs of viral infection were detected, and no cell lines were obtained. studies using fluorescein-labeled ebv and flow cytometry revealed an unusual and consistent deficiency in ebv receptors in all patients examined. in control studies, about 15% of the unseparated lymphocytes from healthy donors bound fluorescein-labeled ebv. in spite of the la ...19836602654
alternative pathway of complement activation by human lymphoblastoid b and t cell lines.other investigators have reported activation of the alternative complement (c) pathway in homologous and heterologous serum by a variety of human lymphoblastoid b cell lines. their ability to activate the c was associated with epstein barr virus transformation of the cells. we report that some human lymphoblastoid t cell lines, lacking ebv-dna in their genome, do activate the human alternative c pathway with no participation of immunoglobulin or specific antibodies. nevertheless, activation meas ...19836604099
chromosome abnormality in a human tcgf-dependent t-lymphocyte culture generated against autologous melanoma cells in vitro.six t-cell growth promoting factor (tcgf)-dependent t-cell cultures and phytohemagglutinin-stimulated peripheral blood lymphocytes from a patient with metatastic malignant melanoma were karyotyped. three of the tcgf-dependent cultures were noncloned, started after in vitro sensitization against autologous malignant melanoma cells in tissue culture. a fourth was a subculture of one of these. the two remaining t-cell cultures were generated by in vitro sensitization of the same individual's lympho ...19836605190
two non-t/non-b leukemia cell lines (thp-3-1 and thp-3-2) established from a patient at different stages of the disease.two leukemia cell lines of different phenotypic expression were established from a single patient with non-t/non-b acute lymphocytic leukemia (all); one (thp-3-1) was derived from the peripheral blood taken on admission before chemotherapy and the other thp-3-2) during the terminal stage. both thp-3-1 and thp-3-2 cells were positive for terminal deoxynucleotidyl transferase (tdt) and ia-like antigen but negative for surface immunoglobulins (ig), nuclear antigen of epstein-barr virus (ebna) and r ...19836605598
a novel hla-d/dr-like antigen specific for human b lymphoid cells. biochemical evidence for similarity to but nonidentity with known hla-d/dr antigens.the polymorphic human b cell-specific antigen, 33.1, detected by a murine monoclonal antibody, was compared by genetics and structural analysis with known human ia antigens from a panel of dr homozygous epstein-barr virus-transformed b lymphoblastoid cell lines. cells homozygous for dr 1, 2, 4, 5, and w6 were positive, while cells that are dr3,3 or dr7,7 usually failed to express this antigen. mutant dr null, dc/mb-positive cells were 33.1 positive while dr null, dc/mb-negative cells failed to e ...19836606012
[human monoclonal antibodies with human-mouse hybridomas].our trial to produce human monoclonal antibodies with human-mouse hybridomas is described. human spleen cells, in comparison with peripheral blood lymphocytes, bone marrow cells and lymphnode lymphocytes, seem to be the best partner to fuse with myeloma line ns-1 to obtain hybridomas. about sixty percent of hybridomas derived from human spleen cells at first produce human ig which in most cases belong to either igg or igm. fifty percent of hybridomas which had initially produced human ig continu ...19836606396
acute cerebellar ataxia and hearing loss as initial symptoms of infectious mononucleosis.a 16-year-old boy had symptoms and signs of cerebellar ataxia and hearing loss. he had no systemic manifestations of infectious mononucleosis and no lymphocytosis. results of a test for infectious mononucleosis were positive and there was a fourfold rise of serum antibody titer to epstein-barr virus capsid antigen. the patient recovered from ataxia but the hearing loss persisted. we reviewed the english literature and 15 cases of cerebellar ataxia associated with infectious mononucleosis were co ...19836625994
estrogen receptor analysis in chronic lymphocytic leukemia.estrogen receptor (er) determinations were performed on cytosol preparations of ficoll-hypaque density separated mononuclear cells from 11 patients with chronic lymphocytic leukemia (cll). the presence of er was noted in 8 of 11 specimens (73%). er ranged from 431 fmole/mg to 4.3 fmole/mg cytosol protein. two types of receptor subunits were observed at the 8s and 4s region of the sucrose gradient. in addition, 1 of 3 epstein-barr virus (ebv) transformed b-lymphoblastoid cell lines from healthy d ...19836626749
a novel japanese burkitt's lymphoma cell line, p32/ishida, with a new variant chromosomal translocation (2;14).a novel cultured cell line, p32/ishida, was established from a japanese 8-year-old boy with abdominal burkitt's lymphoma. the p32/ishida cells were proved to have immature b-cell phenotypes on the basis of immunological surface marker analysis: surface immunoglobulins (gamma, mu, kappa), ia-like antigen, b1 antigen, and common acute lymphoblastic leukemia antigen were positive. a small amount of igm, but no igg, could be detected in both cell extract and culture supernate of p32/ishida cells. cy ...19836667834
