表达APP—C100和SOD1基因突变子的转基因小鼠血管反应性变化的研究
目的:研究转单基因和转双基因小鼠外周微血管反应性改变的作用机制。方法:在未转基因、转单基因和转双基因小鼠的后足爪垫皮肤暴露微血管网,灌注血管扩张剂乙酰胆碱和硝普钠,多普勒检测血液流量变化,应用Western blot检测小鼠外周血β-淀粉样蛋白(Aβ)水平。结果:与未转基因和转单基因(表达SOD1基因突变子G93A)小鼠相比,2-3月龄转单基因(表达APP-C100、TgC100)和转双基因(APP-C100和SOD1基因突变子G93A基因共表达)小鼠外周血液流量下降28%,8-9月龄TgC100小鼠外周血液流量减少34%,TgC100和转双基因小鼠外周血Aβ水平较未转基因小鼠明显升高,差异有...
