The ability to maintain actively proliferating, antigen specific functional T-cells in suspension culture in vitro has allowed the development of cellular and humoral reagents that can be used to dissect regulation of the T-cell immune response. The T-cell proliferation can be divided into four functionally distinct components: interaction of antigen and macrophage and the resultant production of lymphocyte activating factor (LAF, interleukin 1), action of LAF, production of T-cell growth factor (TCGF, interleukin 2) and action of TCGF. A significant portion of physiological regulation of the immune response is mediated at the levels of production and action of these factors. For example, the immunosuppressive effects of glucocorticosteroids are primarily mediated through suppression of TCGF production. Analogous to other polypeptide hormone systems, agonists and antagonists to the LAF or TCGF production or action will have therapeutic importance in states of either hyperimmune reactivity or immunodeficiency.
