Interleukin-2--where are we going?

We have seen many advances in treatment modalities for patients infected with HIV. Trying to improve the immune system of our patients is one of them. An interesting treatment being investigated for this purpose is the use of interleukin-2. Interleukin-2 has been used in many clinical trials and is being used in ongoing trials. The successes/limitations of these trials have given us much information. Is immune reconstitution aided by the use of interleukin-2?
