The murine lymphokine B-cell stimulatory factor 1 (BSF-1) has been described previously in terms of its action on B lymphocytes. We now provide evidence that BSF-1 is also responsible for two additional biological activities. The first of these is the stimulation or maintenance of a state of activation in mouse T-cell lines. The second activity is the increase in the proliferative rate of certain mast cell lines costimulated with interleukin 3. The T-cell and mast cell activities are mediated by purified BSF-1 and copurify with BSF-1 from supernatants of certain T-cell lines. Each of these activities is inhibited by monoclonal anti-BSF-1 but not by monoclonal anti-interleukin 2 antibody. The antibody inhibition results also indicate that BSF-1 is the major or only source of these two activities in the activated T-cell supernatants that we have tested.
鼠淋巴细胞刺激因子1(BSF-1)先前已根据其对B淋巴细胞的作用进行过描述。我们现在提供证据表明,BSF-1还具有另外两种生物学活性。其中第一种是刺激或维持小鼠T细胞系的激活状态。第二种活性是在与白细胞介素3共同刺激时某些肥大细胞系增殖速率的增加。T细胞和肥大细胞活性由纯化的BSF-1介导,并与来自某些T细胞系上清液的BSF-1共纯化。这些活性中的每一种都被抗BSF-1单克隆抗体抑制,但不被抗白细胞介素2单克隆抗体抑制。抗体抑制结果还表明,在我们测试的活化T细胞上清液中,BSF-1是这两种活性的主要或唯一来源。
