据估计,全球有 1.7 亿人感染了致命的丙型肝炎病毒 (HCV)——其中大多数人甚至不知道自己感染了。事实上,该病毒通常会在体内潜伏多年而未被发现,然后最终导致晚期肝病。研究 HCV 的努力一直受到病毒不愿在实验室中生长的阻碍。然而,一项新研究的结果有望改变这种状况。根据今天发表在《科学》杂志上的一份报告,洛克菲勒大学的查尔斯·M·赖斯 (Charles M. Rice) 及其同事发现,某些 HCV 毒株在一种名为 NS5A 的蛋白质的特定区域含有突变,这使得病毒能够在细胞培养物中更自由地复制。利用这一点,该团队开发了一种培养系统,该系统应使研究人员能够在不久的将来更快速地进行病毒的遗传分析和测试化合物药物。此外,对于复制似乎至关重要的 NS5A 区域本身可能代表着一个良好的药物靶点。赖斯说:“这对于病毒的遗传学研究和设计筛选有效药物的方法来说是一项重大突破。” “这真的可以加快药物发现过程。”

Kate Wong is an award-winning science writer and senior editor at 大众科学 focused on evolution, ecology, anthropology, archaeology, paleontology and animal behavior. She is fascinated by human origins, which she has covered for more than 25 years. Recently she has become obsessed with birds. Her reporting has taken her to caves in France and Croatia that Neandertals once called home, to the shores of Kenya's Lake Turkana in search of the oldest stone tools in the world, to Madagascar on an expedition to unearth ancient mammals and dinosaurs, to the icy waters of Antarctica, where humpback whales feast on krill, and on a "Big Day" race around the state of Connecticut to find as many bird species as possible in 24 hours. Kate is co-author, with Donald Johanson, of Lucy's Legacy: The Quest for Human Origins. She holds a bachelor of science degree in biological anthropology and zoology from the University of Michigan.
