Epstein-Barr Virus Transformation Induces B Lymphocytes
Interleukin 10 (I1.10) is a pleiotropic factor that enhances proliferation of activated human B lymphocytes and induces them to secrete high amounts of immunoglobulins. Here we show that several human B cell lines were able to constitutively secrete human (h)Ibl0. Whereas none of the pre-B nor the plasmocytic cell lines tested produced hi1-10, 25 of the 36 tested mature B cell lines (lymphoblas...
متن کاملTransformation of nonhuman primate lymphocytes by Epstein-Barr virus.
Continuous lymphoblastoid cell cultures were established from marmoset (Saguinus sp.), squirrel (SaimirÃ-sciureus), owl (Aotus trivirgatus), and cebus (Cebus apella) monkeys after their peripheral lymphocytes were cultured with lethally, X-irradiated cells carrying Epstein-Barr virus (EBV). Simian lymphocytes were also transformed after exposure to infectious, cell-free EBV derived from some si...
متن کاملEpstein-Barr virus-infected T lymphocytes in Epstein-Barr virus-associated hemophagocytic syndrome.
The clonal composition of EBV-infected cells was examined in three cases of EBV-associated hemophagocytic syndrome by analysis of the heterogeneity of terminal repetitive sequences in the EBV genome, indicating monoclonal expansion of EBV-infected cells in all cases. Involvement of T lymphoid cells was determined by in situ hybridization using 35S-labeled RNA probes specific for the small EBV-e...
متن کاملCharacteristics of Epstein-Barr virus activation of human B lymphocytes
Epstein-Barr virus (EBV) will infect at least every third cell if exposed in vitro to an extensively purified B cell population from human peripheral blood. About 10% of such infected cells will be driven into immunoglobulin synthesis and secretion, as judged by the indirect protein A plaque assay. The appearance of EB nuclear antigen, de novo DNA synthesis, and immunoglobulin secretion are lin...
متن کاملDendritic Cells Initiate Immune Control of Epstein-Barr Virus Transformation of B Lymphocytes In Vitro
The initiation of cell-mediated immunity to Epstein-Barr virus (EBV) has been analyzed with cells from EBV-seronegative blood donors in culture. The addition of dendritic cells (DCs) is essential to prime naive T cells that recognize EBV-latent antigens in enzyme-linked immunospot assays for interferon gamma secretion and eradicate transformed B cells in regression assays. In contrast, DCs are ...
