Analysis of T cell hybridomas. IV. Characterization of inducible suppressor cell hybridomas
The Ts3 subset of suppressor cells is generated after antigen priming, but, in order to express suppressor activity these cells require an additional activation step involving triggering with specific suppressor factors (TsF2). This report characterizes two cloned hybridoma cell lines (pTs3 hybridomas) that represent this stage of Ts3 cell differentiation. These hybridoma cells could be specifi...
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...
متن کاملAntigen-specific, H-2-restricted helper T cell hybridomas
We have examined the carrier-specific helper activity of a number of antigen-specific, I region-restricted T cell hybridomas prepared in our laboratory. The hybridomas were assayed for helper activity in the presence or absence of exogenously added nonspecific factors found in the concanavalin A-activated supernatants of normal mouse spleen cells. Of six hybridomas tested, all six could stimula...
متن کاملAnalysis of T cell hybridomas. I. Characterization of H-2 and Igh- restricted monoclonal suppressor factors
Five hybridoma T cell lines were prepared by fusion of second order suppressor T cells (Ts2) with the BW5147 thymoma. The culture supernates from these T cell hybrids contained a factor, TsF2, which specifically suppressed 4-hydroxy-3-nitrophenyl acetyl hapten (NP)-induced cutaneous sensitivity responses. TsF2 activity was observed when the factor was administered during the effector phases of ...
متن کاملHaplotype-specific suppression of antibody responses in vitro. II. Suppressor factor produced by T cells and T cell hybridomas from mice treated as neonates with semiallogeneic spleen cells
Culture supernatant fluids from spleen cells from C57BL/10 or BALB/c mice neonatally treated with semiallogeneic (B 10.D2 x B10)F1 cells to induce haplotype-specific suppressor T cells and restimulated with macrophages syngeneic at I-A with the allogeneic haplotype encountered as neonates contain a soluble factor capable of suppressing primary in vitro antibody responses of normal syngeneic spl...
