Tissue Drug Levels of HIV Medications

September 21, 2026 updated by: University of Minnesota

A Compartmental Analysis of HIV Reservoirs and Immune Reconstitution

The aim of this study is to find out why HIV continues to make copies in people taking HIV drugs. The investigators want to know if the medications most people use to treat HIV get into the lymphatic tissue where HIV persists.
