摘要
目的研究自发性高血压大鼠(SHR)外周血淋巴细胞电压依赖性钾通道(Kv)、钙激活钾通道(KCa)mRNA表达的变化,探讨淋巴细胞Kv1.3、KCa3.1在高血压病中的变化。方法使用密度离心法采集10只SHR和10只正常Wistar大鼠外周血淋巴细胞,运用实时荧光定量PCR技术检测外周血淋巴细胞Kv1.3、KCa3.1 mRNA表达水平。结果 (1)SHR组Kv1.3 mRNA表达水平高于对照组(P<0.05);(2)与对照组相比,SHR组KCa3.1 mRNA表达水平增高,差异有统计学意义(P<0.05)。(3)SHR收缩压和淋巴细胞Kv1.3、KCa3.1基因表达呈正相关:相关系数为r=0.830,P=0.003;r=0.674,P=0.03。结论 SHR淋巴细胞Kv1.3、KCa3.1 mRNA表达增高,推测淋巴细胞钾通道增多可能与高血压病的发生发展相关。
