Gamma interferon induced surface expression of interleukin 2 (IL-2) receptors on normal human monocytes and the monocytoid cell lines U937 and HL60. These receptors were detected by anti-IL-2 receptor monoclonal antibodies, and U937 IL-2 receptors were indistinguishable from T lymphocyte IL-2 receptors by immunoprecipitation. Also, U937 IL-2 receptors bound biologically active IL-2. These results suggest a role for monocyte IL-2 receptors in T cell/monocyte interaction during an immune response.
γ干扰素可诱导正常人单核细胞以及单核细胞样细胞系U937和HL60表面表达白细胞介素2(IL-2)受体。这些受体通过抗IL-2受体单克隆抗体进行检测,并且通过免疫沉淀法发现U937细胞的IL-2受体与T淋巴细胞的IL-2受体难以区分。此外,U937细胞的IL-2受体可结合具有生物活性的IL-2。这些结果表明单核细胞IL-2受体在免疫应答过程中的T细胞/单核细胞相互作用中发挥作用。
