"Shock & kill" approach cures mice of HIV in world first


Credit: scottcamazine.com

One of the difficulties involved with treating AIDS is that the HIV virus, which causes the disease, is able to "hide" from treatment.

A new approach uses a combination of drugs, one of which provides a boost to the immune system, & others which flush the HIV virus from its hiding places. When flushed from their hiding places, the virus particles can be killed by the boosted immune system. Only tested in mice so far, but looks promising.
