CsA interferes in a specific manner with the expansion of T cell clones in that it inhibits the antigen-driven component of the proliferative responses made by cloned helper T cells, cloned conventional cytolytic T cells, and cloned helper-independent cytolytic T cells. Cloned helper T cells and helper-independent cytolytic T cells, which share the ability to proliferate when cultured with specific alloantigen, fail to proliferate when cultured with specific alloantigen, fail to proliferate in response to this stimulus in the presence of CsA (10 to 100 ng/ml). In contrast, the proliferation observed when these cells are cultured with exogenous growth factors (but not alloantigen) is little influenced by as much as 1000 ng/ml CsA. When cloned helper T cells or helper-independent cytotoxic T cells are cultured with alloantigen plus exogenous growth factor, additive or synergistic proliferation occurs. However, CsA (10 to 1000 ng/ml) blocks only the component of proliferation induced by alloantigen, and leaves the lymphokine-driven component intact. CsA has similar effects on the proliferation of cloned conventional cytolytic T cells. Thus, CsA separates cloned T cell proliferation into two components: one driven by contact with alloantigens, the other driven by contact with mitogenic lymphokines.
