| blastogenic response of purified human t-lymphocyte populations to epstein-barr virus (ebv). | the blastogenic response of t-cell populations to infectious ebv (b95-8 strain) was studied. the addition of virus increased the [3h]thymidine uptake of unfractionated lymphocytes from seropositive and seronegative subjects, and from cord blood, but not from patients with infectious mononucleosis. the same amount of virus evoked a small response in purified t cells from seropositive donors, but not in t cells from the other sources. the addition of autologous b lymphocytes with ebv adsorbed on t ... | 1977 | 203426 |
| 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 ... | 1978 | 203544 |

| 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. | 1978 | 205852 |
| 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 ... | 1978 | 205853 |
| 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. | 1978 | 205854 |
| 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 ... | 1978 | 205860 |
| 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 ... | 1978 | 205877 |

| 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. | 1978 | 206347 |
| 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 ... | 1978 | 206349 |
