MadSci Network: Immunology |
You have a pretty good idea, but here is why it unfortunately wouldn't work. The virus that causes AIDS, the human immunodeficiency virus (HIV), infects many cells all throughout the body, not just cells in the blood. Examples of some organs where lots of virus-infected cells are present include the spleen and lymph nodes. Draining the blood wouldn't remove the infected cells from these organs, and so virus would just return to the blood quickly after replacement. As far as treatment for HIV right now, the best available medicines block the replication and infection-process of the virus. This way, any cells which are not yet infected won't become infected by virus spreading from already infected cells. These drugs have proven to be very effective at letting people with AIDS live longer and healthier lives. Unfortunately, eventually the virus changes in a way to make the drugs less and less effective, and eventually the person will become very sick with AIDS. Right now there is no cure, although a great deal of research is going on, searching for both a cure and a vaccine, to prevent the spread of the virus from person to person. Hope this helps.
