Medical researchers have gained a significant insight into how the virus that causes AIDS hides in the body as it dodges medicines that are designed to kill it off. Scientists at the University of Michigan have found that a reservoir of dormant cells in bone marrow serves as a holding cell, from which the virus can roar back into action as soon as the drugs are gone.
The scientists say the research opens the door to a new field of study that could eventually reduce the drug burden on HIV patients

KATHLEEN COLLINS: Well, what we found that there was evidence that HIV in fact, does infect the bone marrow progenitor cells or parent cells that are the source of all of the different blood lineages in the body and moreover that HIV can take on a latent form and so we were able to detect the presence of virus ending cells even after patients had been on therapy for years.
ASHLEY HALL: It's not the first time scientists have found reservoirs of the virus in the body. They've already found HIV hiding out in blood cells called macrophages and in the immune cells known as memory T-cells. But scientists believed there was at least one more major reservoir of the virus in the body and Dr Collins' team thought just maybe that was bone marrow.
