We have previously characterized a macrophage hybridoma clone, termed clone 59, which induced immunity but consistently failed to induce Ts responses. Macrophage 59 cells were cultured with supernatants from several activated T cell clones to determine if lymphokines could modulate the activity of this macrophage hybridoma to generate effector Ts. Culture supernatants from Th1 clones and from one atypical IL-4 and IFN-gamma-producing T cell clone successfully modulated clone 59 cells to induce effector Ts cells. In contrast, supernatants from activated Th2 cells failed to generate Ts-inducing activity in macrophage 59 cells. Culture with recombinant derived IFN-gamma was sufficient to cause modulation of Ts-inducing activity in macrophage 59 cells. The data imply that the differential functional activities ascribed to various macrophage hybridoma clones reflect macrophage heterogeneity instead of independent macrophage lineages. The suppression induced by clone 59 macrophages was genetically restricted to the putative I-J region. The ability of IFN-gamma containing supernatants to endow macrophage 59 with the capacity to induce effector suppressor cells was specifically abrogated by addition of an anti-IJk-idiotype antibody, which also reacts with IJ-interaction molecules, indicating that the mechanism of modulation most likely involves expression of IJ-interaction molecule determinants on antigen presenting cells.
