Acta Neuropathologica:在英国,接触疯牛病前后人类阑尾中异常朊蛋白的流行情况。

2020-07-28 网络 网络

在20世纪80年代和90年代,英国人饮食普遍暴露于牛海绵状脑病(BSE)朊病毒,导致变异克雅氏病(vCJD)的出现。

在20世纪80年代末和90年代初,英国人对牛海绵状脑病(BSE)朊病毒的饮食暴露引起了变异克雅氏病(vCJD)的出现。这种朊病毒病的特点在于它一种不同于其他形式的人类朊病毒病的菌株,能产生独特的临床图像、生化模式和组织病理学外观。受vCJD影响而死亡的人明显比死于散发性朊病毒疾病的人年轻。vCJD的一个特征是异常朊病毒蛋白(PrP)的聚集,这是正常宿主朊病毒蛋白在淋巴网状系统中的错误折叠形式,如在肠道器官中的淋巴结、扁桃体、脾脏和淋巴滤泡。本实验对1962年至1979年以及2000年至2014年中接受阑尾手术的病人中取出的29516份标本进行了异常PrP的免疫组化检测。

方法:收集并存档来自英国病理科的阑尾标本(多达40000份),其中20000份来自1980年以前的阑尾切除术,另外20000份来自2000年至2014年间手术的阑尾样本,后者样本来自1996年或1996年后出生的人。由于预计约25%的样本不适合进行IHC测试,因此将检查约30000个样本来确定是否存在异常PrP。这些样本在实验室进行切片、IHC染色、初筛和专家显微镜检查。每个阑尾块上切下一组三个切片,再进行切片制备及免疫组化检测。

结果:在29516份受检样本中,7份阑尾样本内发现异常PrP积聚,其中2个来自BSE暴露前时期,5个来自BSE暴露后时期。这7份阳性样本均来自1977年以前切除的阑尾或在2000年后出生的患者,没有来自诊断为vCJD的患者。研究结果表明,在假定的疯牛病流行之前和1996年之后,英国食物链中与疯牛病相关的朊病毒接触被认为"极低"之后,都有可能出现异常朊病毒接触。
