The effect of IL-2, IL-3, IL-4 and GM-CSF on beta-adrenoceptor function of human peripheral blood mononuclear cells (PBMC) was studied. After a 2 h pre-incubation period of PBMC with each of the lymphokines (1-100 units/ml), the isoprenaline stimulated cAMP production in these cells was not altered. However, IL-2 and GM-CSF induced a concentration dependent decrease of the beta-adrenoceptor agonist stimulated cAMP production after a 20 h pre-incubation period.
研究了白细胞介素-2(IL-2)、白细胞介素-3(IL-3)、白细胞介素-4(IL-4)和粒细胞巨噬细胞集落刺激因子(GM-CSF)对人外周血单个核细胞(PBMC)β-肾上腺素能受体功能的影响。在PBMC与每种淋巴因子(1-100单位/毫升)预孵育2小时后,异丙肾上腺素刺激这些细胞中cAMP的产生没有改变。然而,在预孵育20小时后,IL-2和GM-CSF诱导β-肾上腺素能受体激动剂刺激的cAMP产生呈浓度依赖性下降。
