Culture supernatants generated by alloantigenic or lectin stimulation of a cloned helper T lymphocyte, designated L2, contain interleukin 2 (IL2), granulocyte/macrophage colony-stimulating factor (CSF), B cell stimulating factor (BCSF), macrophage (Ia +)-recruiting factor (MIRF), (Ia +)-inducing activity, γ-interferon, Fc receptor-enhancing activity, macrophage migration inhibitory factor (MIF), macrophage activation factor (MAF), interleukin 3 (IL 3), and a factor responsible for prolonging the synthesis and secretion of the fourth and second components of complement by guinea pig peritoneal macrophages. Erythropoietin was not detected. A spontaneously arising variant of L2, designated L2V, produces much lower quantities of macrophage-stimulating activities, IL 2, and interferon. However, when compared to L2, L2V produces much higher levels of BCSF, equivalent amounts of IL 3, and slightly smaller amounts of CSF. Unlike L2V, a cytolytic clone, designated L3, secretes lymphokines that primarily affect macrophage function. The time course of lymphokine production by L2 cells indicates that for the six lymphokine activities studied there are three different times at which maximal or near maximal levels are reached, as follows: 1) IL 2, 12 to 24 hr; 2) IL 3 and CSF, 24 to 48 hr; and 3) (Ia +)-inducing activity, MAF, and interferon, 48 hr or later. Only IL 2 activity disappears during the 8-day culture cycle. The time course data and the differential production of activities by the three types of lymphocyte clones suggest that at least four terminal effector lymphokine molecules account for the ten biologic activities tested.
