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 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 کاملFunctional analysis of Histoplasma capsulatum-reactive T-cell hybridomas.
Activation of CD4+ T cells is a crucial step in the elimination of Histoplasma capsulatum yeast cells from tissues. However, only a limited amount of information exists concerning the immunobiology of H. capsulatum-reactive T cells that are CD4+. To facilitate the analysis of the functional activities of this T-cell subpopulation, we developed a panel of 10 murine T-cell hybridomas from splenoc...
متن کاملAnalysis of T cell hybridomas. II. Comparisons among three distinct types of monoclonal suppressor factors
Five hybridoma T cell lines were prepared by fusion of Ts3 cells with the BW 5147 thymoma. The culture supernatants from these T cell hybrids contained a factor, TsF3, which specifically suppressed 4-hydroxy-3-nitrophenyl acetyl hapten (NP(-hapten cutaneous sensitivity responses. The properties of this new series of hybridoma factors was compared with those of two previously characterized types...
متن کاملAntigen presentation to T cell hybridomas by a macrophage cell line: an inducible function.
We have investigated the ability of an Ia-, nonantigen-presenting macrophage tumor cell line, P388D, (H-2d), to present antigen to T cell hybridomas after incubation in a lymphokine-containing preparation. P388D, cells were incubated in microtiter wells with various concentrations of Con A-stimulated spleen cell supernatants. Antigen-specific stimulation of H-2d-restricted, KLH-specific T cell ...
