摘要 核转录因子NF-kB由Sen等在1986年首先发现于B淋巴细胞,它可与免疫球蛋白的k轻链基因增强子10bp DNA序列(5′-GGGACTTTCC-3′)特异结合,调控免疫球蛋白k轻链的转录。NF-kB活化存在正负反馈两种途径。例如炎症刺激时可使内皮细胞的NF-kB活化,促进内皮细胞分泌TNF-α,而TNF-α又是NF-kB的激活剂,通过正反馈作用,进一步激活NF-kB,增加其它细胞因子的分泌,引起级联反应(cascades)。而负反馈途径主要是ⅠkBα亚基的增加及P50同源二聚体的增多,与NF-kB竞争结合kB序列从而抑制其活性。NF-kB在心肌细胞中扮有重要的角色,其与心肌细胞凋亡、心肌缺血-再灌注、心肌中的抑制剂等有着密不可分的关系。对这几个方面做一简述。
