HIV Can Dodge Drugs By Hiding in Bone Marrow

The virus that causes AIDS can hide in the bone marrow, avoiding drugs and later awakening to cause illness, says new research that could point the way toward better treatments for the disease. Finding that hide–out is a first step, but years of research lie ahead.

Kathleen Collins of the University of Michigan and her colleagues report in the journal Nature Medicine that the HIV virus can infect longlived bone marrow cells that eventually convert into blood cells.

The virus is dormant in the bone marrow cells, she said, but when those progenitor cells develop into blood cells, it can be reactivated and cause renewed infection. The virus kills the new blood cells and then moves on to infect other cells, she said. “If we’re ever going to be able to find a way to get rid of the cells, the first step is to understand” where a latent infection can continue, Collins said.

Eliminating these sources of infection would allow AIDS patients to stop taking drugs after their infection was over. That’s critical in countries where the treatment is hard to afford and deliver.
