据报道,活化的T 淋巴细胞具有胰岛素和胰岛素生长因子-1(IGF-1)受体,但关于淋巴细胞上这两类受体的功能尚不甚清楚,本文对此进行了研究。已知血清中存在能增强人淋巴细胞增殖反应的因子,故作者先测定了不同厂家生产的不同批号胎牛血清中的胰岛素和IGF-1含量。结果发现在5批胎牛血清中,IGF-1的平均含量为138ng/ml,其浓度范围是1～2×10~(-8)M,而胰岛素的浓度范围是 Activated T lymphocytes have been reported to have insulin and insulin-like growth factor-1 (IGF-1) receptors, but the function of these two classes of receptors on lymphocytes is unclear, and this article has been studied. It is known that there is a factor that can increase the human lymphocyte proliferation reaction in serum. Therefore, the authors first determined the contents of insulin and IGF-1 in different batches of fetal bovine serum produced by different manufacturers. As a result, it was found that in 5 batches of fetal bovine serum, the average level of IGF-1 was 138 ng / ml, and the concentration range of IGF-1 was 1-2 × 10 -8 M while the concentration range of insulin was
