Antiretroviral Localization in Gut-Associated Lymphoid Tissue and Lower Female Genital Tract Tissue of HIV+ Subjects

The purpose of this research study is to find out how the drugs Truvada® (tenofovir/emtricitabine), Isentress® (raltegravir), Reyataz® (atazanavir), Sustiva® (efavirenz), and Selzentry® (maraviroc) get into the intestines and the female genital tract. All of these drugs are very effective at reducing the number of HIV viruses in the blood, however it is unknown how the drugs move around inside tissues where HIV might be hiding. This study will determine specifically where in the tissue the drug and the HIV are located through the use of a new technology that takes creates a picture of the tissue. This information will help scientists determine the best way to make new drugs to target the hidden HIV in tissue.
