Different antigen-presenting cells differ in their capacity to induce lymphokine production and proliferation of an apo-cytochrome c-specific T cell clone.
The activation of an apo-cytochrome c-specific T cell clone was found to differ, depending on the antigen-presenting cell population. Whereas total syngeneic spleen cells and bone marrow macrophages could be shown to trigger proliferation, IL 2, and MAF production by the T cell clone, a B cell lymphoma only induced MAF secretion. Further studies demonstrated that this effect was not due to a different antigen processing by the B lymphoma or to limiting amounts of Ia and antigen molecules on the B lymphoma cell surface. The dissociation of induction of MAF production from IL-2 production/proliferation found with the different antigen-presenting cells indicates strongly that molecules other than Ia and antigen may be required for the complete functional activation of antigen-specific T cell clones.
