A new dwelling of HIV-infected cells has been brought to notice by Researchers at University of Michigan. The findings also point towards a new target for getting a new remedy for the disease; hence the infected ones need not rely on AIDS drug throughout their life.

It is revealed in a latest study that the virus lurks in the bone marrow cells and comes back to life under specific circumstances.

"Antiviral drugs have been effective at keeping the virus at bay. However once the drug therapy is stopped, the virus comes back", Nature quoted senior author of the study Dr Kathleen L. Collins, as saying.

People infected with human immunodeficiency virus who are consuming anti-viral drugs can't get rid of the virus for good. Infected cells will continue to dwell in the body, unnoticed by the immune system and will supply machinery for the dreadful virus to multiply.

The study has revealed that bone marrow may contain some hidden infection, which earlier was thought of as resistant to the virus. Currently used anti-HIV drug treatments have no effect on them.

Collins said, "Currently people have to take anti-viral drugs for their entire life to control the infection. It would be easier to treat this disease in countries that don't have the same resources as we do with a course of therapy for a few months, or even years. But based on what we know now people have to stay on drugs for their entire life".
