Science:VirScan可揭示一个人完整的病毒接触史

2015-06-05 coo 生物360

一种叫做VirScan的新技术只需不到一滴血的量便能确定一个人在其一生中所接触过的所有病毒。研究人员对来自世界各地569人使用了该筛检技术并发现,平均而言,他们的实验参与者在其一生中接触过大约10种病毒。VirScan为研究人类病毒组(已知会感染人的各种病毒汇集)和免疫系统(它会因接触病毒而永久性地改变)之间的相互作用提供了一个强有力而且廉价的工具。在此之前,用来检测病毒遗留下来的无法抹灭足迹的血

一种叫做VirScan的新技术只需不到一滴血的量便能确定一个人在其一生中所接触过的所有病毒。研究人员对来自世界各地569人使用了该筛检技术并发现,平均而言,他们的实验参与者在其一生中接触过大约10种病毒。

VirScan为研究人类病毒组(已知会感染人的各种病毒汇集)和免疫系统(它会因接触病毒而永久性地改变)之间的相互作用提供了一个强有力而且廉价的工具。在此之前,用来检测病毒遗留下来的无法抹灭足迹的血液化验(即免疫系统所分泌的抗体)受到了其所能筛检病毒数目的限制。

为了扩大这些化验所能涵盖的范围,George Xu和同事用采自206种病毒的一个大型病毒肽数据集(它代表了1000多不同的病毒株)创建了一个所有人类病毒肽的综合代表。用这一模板,他们能筛检血样本中的病毒抗体,而每个样本的筛检价格只要25美元。这些来自不同研究参与者(他们来自4个不同的大陆)的样本揭示了超过1.06亿种肽-抗体相互作用。多人接触过大约10种病毒,但至少有一些志愿者接触过84种病毒。

这些发现凸显了保守的免疫应答(或称“公共抗原表位”)并表明个人可能会因应相同的病毒而分泌类似的抗体--尽管人们接触病毒的比率是大相径庭的。Xu和他的同事提出,VirScan的精度可用更多的血样本来提高,且未来它可能还会适用于细菌、真菌或原生动物。
