In the current issue of Nature Medicine, scientists have proven what they long suspected – that HIV can hide in our bone marrow and avoid eradication by HIV drugs. Current medications can reduce HIV levels in the blood to an undetectable amount. But, the virus can often come surging back when one stops taking medication because our current drugs do not attack the bone marrow cells which harbor dormant viruses. Why not? Because if we completely kill off all our marrow cells our body cannot produce blood, which would essentially be fatal. However, we now have a new target for future medications to act. And, who knows, we may discover even more places where the virus is able to hide and evade attack.
