当新的HIV病毒颗粒从被感染的细胞中出芽时,一种被称作蛋白酶(protease)的酶被激活从而协助HIV成熟和感染更多的细胞。这就是为什么现代的AIDS(获得性免疫缺陷综合征,由HIV感染导致的一种疾病)药物通过抑制蛋白酶控制这种疾病。在一项新的研究中,来自美国犹他大学的研究人员发现一种将蛋白酶变成双刃剑的方法:他们证实如果他们延迟新的HIV颗粒出芽, As new HIV virus particles sprout from infected cells, an enzyme called protease is activated to help HIV mature and infect more cells. This is why modern AIDS (Acquired Immune Deficiency Syndrome), a disease caused by HIV infection, controls this disease by inhibiting proteases. In a new study, researchers from the University of Utah found a way to turn proteases into double-edged sword: They showed that if they delayed budding of new HIV particles,
