Abstract

BDF1 [(C57BL/6 x DBA/2)F1] mice were primed with alum-absorbed ovalbumin, and their spleen cells were cultured with ovalbumin to activate antigen-primed T cells. The activated T cells were then propagated in interleukin 2-containing medium in the presence or absence of affinity-purified glycosylation-inhibiting factor (GIF). Upon incubation with ovalbumin-pulsed macrophages, T cells propagated in the absence of GIF produced IgE-potentiating factor and glycosylation-enhancing factor. In contrast, T cells propagated in the presence of GIF produced IgE-suppressive factor and GIF. The ovalbumin-primed T cells propagated in the presence of GIF constitutively produced the 13-kDa GIF that lacked affinity for ovalbumin. However, stimulation of the same T cells with ovalbumin-pulsed macrophages resulted in the production of 80- and 35-kDa GIF that had affinity for ovalbumin. Both the antigen-specific GIF and nonspecific GIF from the activated BDF1 T cells had I-Jb determinants. Since the ovalbumin-specific GIF is derived from Lyt-2+, I-J+ ovalbumin-specific suppressor T cells and suppresses the anti-hapten antibody response to dinitrophenyl-coupled ovalbumin, the results strongly suggest that the presence of GIF during the propagation of antigen-primed T cells facilitates the generation of antigen-specific suppressor T cells.
