With the description of lymphocyte-derived growth factor activities in the 1960s and 1970s, it was realized that activated lymphocytes secrete soluble factors that are critical for subsequent lymphocyte proliferation [ 2 3 ] . Moreover, in 1967 it was demonstrated that monocytes or macrophages serve as necessary accessory cells for the lymphocyte activation process [ 4 ] . Then, in the early 1970s several reports indicated that mitogen- or endotoxin-stimulated macrophages release soluble lymphocyte activating factors (LAFs) that also amplify the activation process [ 5 6 ] . Accordingly, lymphokines and monokines, which collectively came to be known as cytokines, became prime research subjects for those interested in lymphocyte activation [ 7 8 ] . However, it was not until the 1980s that the cell surface and soluble molecules responsible for the complex cellular changes of lymphocyte activation were identified.
The molecules responsible for the contribution by the soluble macrophage-derived LAFs still remain obscure, even today.
