The word lentivirus has its root in the Latin “lentus,” which means slow or lingering — an apt description for the chronic, persistent infections the virus causes in animals and people. For the past 25 years, Susan Carpenter has studied the genetic strategies that allow lentiviruses to linger. The professor of animal science studies equine infectious anemia virus, a lentivirus that afflicts horses and is a close relative of human immunodeficiency virus, HIV. That makes it a good model to inform new vaccine strategies for HIV and other persistent viruses and prevent the progression to AIDS and some cancers.
