CaMKⅡ在8-Br-cAMP诱发的脊髓背角LTP中的作用
摘要
目的:探讨钙-钙调蛋白依赖性蛋白激酶Ⅱ(CaMKⅡ)在8-Br-cAMP诱发的脊髓背角长时程增强(LTP)中的作用。方法:采用SD大鼠,常规细胞外记录技术记录脊髓背角腰膨大部位浅层C-纤维诱发电位。结果:①8-Br-cAMP(1mmol/L)诱发的脊髓背角LTP咬合(occlude)强直刺激诱导的LTP;②CaMKⅡ选择性抑制剂KN-93(100μmol/L)或AIP(200μmol/L)阻断8-Br-cAMP诱导的脊髓背角LTP;③蛋白质合成抑制剂茴香霉素(200μmol/L)抑制8-Br-cAMP诱发的脊髓LTP。结论:CaMKⅡ参与8-Br-cAMP诱导的脊髓背角C-纤维诱发的LTP;8-Br-cAMP诱导的LTP与强直电刺激诱导的LTP在机制上至少存在部分相同的步骤或途径。
