Cancer drug shocks HIV out of hiding

Image
HIV is an exceptional adversary. It is more diverse than any other virus, and it attacks the very immune cells that are meant to destroy it. If that wasn’t bad enough, it also has a stealth mode. The virus can smuggle its genes into those of long-lived white blood cells, and lie dormant for years. This “latent” form doesn’t cause disease, but it’s also invisible to the immune system and to anti-HIV drugs. This viral reservoir turns HIV infection into a life sentence.

When the virus awakens, it can trigger new bouts of infection – a risk that forces HIV patients to stay on treatments for life. It’s clear that if we’re going to cure HIV for good, we need some way of rousing these dormant viruses from their rest and eliminating them.

A team of US scientists led by David Margolis has found that vorinostat – a drug used to treat lymphoma – can do exactly that. It shocks HIV out of hiding. While other chemicals have disrupted dormant HIV within cells in a dish , this is the first time that any substance has done the same thing in actual people.

At this stage, Margolis’s study just proves the concept – it shows that disrupting HIV’s dormancy is possible, but not what happens afterwards. The idea is that the awakened viruses would either kill the cell, or alert the immune system to do the job. Drugs could then stop the fresh viruses from infecting healthy cells. If all the hidden viruses could be activated, it should be possible to completely drain the reservoir. For now, that’s still a very big if, but Margolis’s study is a step in the right direction.
