Antiretroviral treatments sometimes fail to work in people with HIV because of the virus' ability to "hide" in cells and then reemerge once therapy stops. Norway's Bionor tested anticancer drug romidepsin and a vaccine, Vacc-4x, in 17 HIV-positive patients in the hopes that the combo would force the virus out of hiding and then kill it.

> Researchers from the University of Texas Health Science Center and the National School of Tropical Medicine at Baylor College of Medicine identified how the parasite that causes Chagas disease evades the immune system. The parasite, T. cruzi, uses a protein to hide, allowing it to stay hidden for decades. Read more
