CELL GROWTH FACTOR SECRETING HUMAN T - T CELL HYBRIDOMA TABLE I Development and Screening of Human T Cell Hybridomas
The development of human T cell hybridomas secreting immunoregulatory molecules has been an area of recent intense interest and investigation. Functional hybrids derived from both normal and malignant human T cells have been developed. These hybrids have been demonstrated to secrete interleukin 2 (IL-2) 1 (1), killer helper factor (2), and factors that help or suppress immunoglobulin production...
متن کاملConstruction of T cell hybridomas secreting allogeneic effect factor
T cell hybridoma lines were constructed by fusion of DBA/2 alloantigen-activated T cell blasts with the AKR thymoma line BW5147. Certain of the hybridomas prepared in this manner secreted spontaneously into their culture supernates biologically active molecules that displayed B cell- and T cell-activating properties characteristic of allogeneic effect factor (AEF). Cell surface phenotype analys...
متن کاملHuman T cell hybridomas secreting factors for IgA-specific help, polyclonal B cell activation, and B cell proliferation
Human T-T hybridomas were established by fusion of concanavalin A-activated OKT-4+ T cells with hypoxanthine guanine phosphoribosyl transferase-deficient as well as nondeficient T cell lines. Four hybrids were selected for further study. Supernatant from hybrid clone J1.3 specifically enhanced IgA production and secretion by isolated human B cells, with increases in IgA plaque-forming cells app...
متن کاملCharacterization of human hybridomas secreting antibody to tetanus toxoid.
We have selected a thioguanine-resistant lymphoblastoid cell line (LTR228) that forms human-human hybrids with high efficiency. Fusions with peripheral B cells consistently yield one colony per 10(5) cells plated. To produce antitetanus monoclonal antibodies, we withdrew blood from persons who had recently received booster injections of tetanus toxoid. T cells were separated from peripheral mon...
متن کاملAntigen-specific human T-cell hybridomas with helper activity.
Human T cell hybridomas were produced by fusing the hypoxanthine phosphoribosyltransferase-deficient line of the human T cell lymphoma Jurkat with a continuous line of normal human T cells specific for tetanus toxoid (TeT). The hybridomas were selected for their ability to produce interleukin 2 after exposure to TeT on semiautologous monocytes and for their ability to bind to TeT-pulsed semiaut...
