An Ag-specific interleukin 1 (IL-1)-dependent bovine CD4+ Th cell clone, termed 300B1, was isolated and found to resemble the previously described IL-1-dependent murine CD4+ Th2 cell clone, D10.G4.1. Both the 300B1 and the D10.G4. 1 T cell clones proliferated to bovine (Bo) IL-1β human (Hu) IL-1α and IL-1β, and murine IL-1α when cells were costimulated with concanavalin A (Con A). Proliferation of the 300B1 clone, when costimulated with Con A, appeared to be IL-1 -specific in that proliferation could not be promoted by BoIL-2, HuIL-3, HuIL-4, HuIL-5, or HuIL-6. The 300B1 clone produced interferon-γ (IFN-γ), but not IL-2 following stimulation with either Con A, Con A plus phorbol 12-myristate 13-acetate or Ag plus antigen-presenting cells. Upon stimulation with Con A, the 300B1 clone expressed IL-4 mRNA and produced an automne growth factor (AGF) that could be inhibited by anti-HuIL-4 but not by anti-HuIL-2 Ab. The clonal derivation of the 300B1 clone was confirmed by isolating five 300B1 subclones, all of which produced IFN-γ and an AGF but not IL-2. Collectively, these results suggest the IL-1-dependent bovine 300B1 Th cell clone produces IL-4, but not IL-2, as an AGF. Furthermore, the bovine Th cell clone appeared to share many characteristics of previously described murine Th2 cell clones except that the bovine clone produced IFN-γ.
