Description of intervention(s) / exposure
Treatment: Surgery - Leukapheresis
Treatment: Surgery - Lymph node biopsy

HIV infected individuals on long term ART - * Leukapheresis
* Lymph node biopsy


Treatment: Surgery: Leukapheresis
Blood will be taken by a needle inserted into a vein in one arm and processed through a machine, which spins the blood so that the white blood cells will be separated out of the machine for purposes of this research. The rest of the blood will be returned through a needle in the other arm.

Treatment: Surgery: Lymph node biopsy
Ultrasound will be used to localize the position of one lymph node in the groin. Under a light general anesthetic, one lymph node will be removed.

Summary
Brief summary
The aim of this project is to determine whether latent HIV is enriched in cells expressing certain proteins (receptors) on their surface and whether it is possible to eliminate these cells through the use of drugs that specifically target these proteins. Lymph nodes are known to contain very high numbers of HIV infected cells.
