HIV can only bond with a special receptor on white blood cells called the CD4 receptor. These receptors are special proteins that exist on the outside of white blood cells.

In the lab we can make CD4 receptors with ease and then inject them into the patient's blood stream without causing any harm. These free floating receptors then attach to HIV floating in the blood and cause it to become harmless. We can even attach the CD4 receptors in large numbers to a bigger molecule, so they can be filtered out of the blood by the kidneys. This dramatically reduces the amount of HIV in the blood by tricking it into bonding with a significantly larger number of either free floating or CD4 receptors bonded with larger harmless molecules. Regular treatments could completely eliminate the risk of HIV causing any significant damage to the immune system and developing into AIDS.

The second line of defense is to protect all the healthy white bloods cells in the patient, so the immune system can get back to normal. Since CD4 receptors serve no purpose in the body and some people don't even have them, we can create complimentary molecules to bond with and essentially cap the CD4 receptors. The last time I checked there were close to 200 commercially available injectable medicines that served this purpose. The down side is that new white blood cells would not be protected, so regular injections would be necessary and the CD4 receptor problem would not be permanently solved. However, we can work backwards chemically to identify the segment of DNA that results in a person having CD4 receptors and replace that segment of DNA using genetic medicines to permanently eliminate the problem. Or we can trick the ribosomes into creating proteins that will cap the CD4 receptors throughout an individual's lifetime by adding a segment with instructions to make the new protein.

So here is a cure to eliminate HIV and provide significant immunity to acquiring AIDS.
