Expression of a highly specific protein inhibitor for cyclic AMP-dependent protein kinases in interleukin-1 (IL-1)-responsive cells blocked IL-1-induced gene transcription that was driven by the kappa immunoglobulin enhancer or the human immunodeficiency virus long terminal repeat. This inhibitor did not affect protein kinase C-mediated gene transcription, suggesting that cyclic AMP-dependent protein kinases are involved in the signal transduction pathway for IL-1 in a number of responsive cell types.
在白细胞介素-1(IL-1)应答细胞中,一种针对环磷酸腺苷(cAMP)依赖性蛋白激酶的高度特异性蛋白抑制剂的表达,阻断了由κ免疫球蛋白增强子或人类免疫缺陷病毒长末端重复序列驱动的IL-1诱导的基因转录。该抑制剂不影响蛋白激酶C介导的基因转录,这表明cAMP依赖性蛋白激酶在多种应答细胞类型中参与了IL-1的信号转导途径。
