Purified interleukin 2 (IL-2) was found to be sufficient for direct activation of peripheral blood lymphocytes into lymphokine-activated killer (LAK) cells. The LAK activation factor was directly and consistently associated with IL-2 activity using classic protein purification techniques, adsorption to IL-2-dependent cell lines, and inhibition with anti-Tac antibody. As yet, no other cytokines have been found that perform the same role.
纯化的白细胞介素2(IL-2)被发现足以将外周血淋巴细胞直接激活为淋巴因子激活的杀伤细胞(LAK细胞)。使用经典的蛋白质纯化技术、吸附到依赖IL-2的细胞系以及用抗Tac抗体抑制,LAK激活因子与IL-2活性直接且始终相关。迄今为止,尚未发现其他细胞因子具有相同的作用。
