从静息前体产生效应细胞毒性T淋巴细胞通过途径中的一系列步骤进行,所述途径总体上涉及细胞毒性的增殖和发展1 -7。为了理解导致沿着该途径进展的各种信号(促分裂原和/或淋巴因子)的关系,需要定义一系列“最小信号”,其中每一个都刺激细胞在该分化过程中进行到另一个阶段。刺激淋巴细胞与两种不同的单克隆抗体直接针对CD 2表面分子诱导增殖response 8;我们在这里报告,CD 4+和CD 8+细胞增殖响应这样的刺激,但不发展细胞毒性。向活化细胞中加入重组γ-干扰素(rIFN-γ)或重组IL-2(rIL-2)导致CD 8+细胞获得细胞毒性状态,但CD 4+细胞不获得。可用性,除了前体和效应,一个明显的中间阶段的形式增殖的CD 8+细胞是非细胞毒性的,应促进细胞和分子研究的这种成熟途径; CD 4+和CD 8+细胞之间的差异,在这些实验条件下的细胞毒性的发展是一个有价值的模型,了解T淋巴细胞的分化。
The generation of effector cytotoxic T lymphocytes from resting precursors proceeds through a series of steps in a pathway that, in aggregate, involves both proliferation and development of cytotoxicity1–7. To understand the relationship of the various signals (mitogens and/or lymphokines) that bring about progress along this pathway, it is desirable to define a series of 'minimal signals', each of which stimulates the cell to proceed to a further stage in this process of differentiation. Stimulation of lymphocytes with two different monoclonal antibodies directed against the CD2 surface molecule induces a proliferative response8; we report here that both CD4+ and CD8+ cells proliferate in response to such a stimulus but do not develop cytotoxicity. Addition of recombinant γ-interferon (rIFN-γ) or recombinant IL-2 (rIL-2) to the activated cells leads to acquisition of cytotoxic status by the CD8+ cells but not the CD4+ cells. The availability, in addition to precursors and effectors, of an apparently intermediate stage in the form of proliferating CD8+ cells that are non-cytotoxic should facilitate both cellular and molecular studies of this maturation pathway; the differences between CD4+ and CD8+ cells in development of cytotoxicity under these experimental conditions is a valuable model for understanding differentiation of T lymphocytes.
