|Brief Title ICMJE||Studies of Blood and Reproductive Fluids in HIV-Infected and Non-HIV-Infected Persons|

This study will examine the effects of HIV infection on substances produced by immune cells that increase or decrease HIV infection.
HIV-infected patients and healthy normal volunteers may be eligible for this study. Participants will be required to have a yearly medical evaluation, including blood tests for cell counts and chemistries, a blood or urine pregnancy test for women, and other laboratory tests as medically indicated or for research purposes.
Participants will donate blood or reproductive fluids, or both. From 20 to 150 cc (4 to 30 teaspoonfuls) of blood will be drawn from the arm using a small needle. Participants may be asked to provide blood samples on more than one occasion over the course of the study. No more than 450 cc (less than 1 pint) of blood will be drawn during any 6-week period. Males will be given a private room for semen donation; fluid from females will be collected with a cotton swab after speculum insertion. Participants may also be asked to have a buccal swab. For this procedure, the inside of the cheek is gently scraped with a blunt-ended stick or brush to obtain cells (buccal mucosal cells). The tissues will be used for a variety of studies on the effects of HIV infection on factors that increase or decrease HIV infection.
Some of the tissues collected for this study may also be used for the following tests:
We are studying the pathogenesis of HIV infection. Because of the lack of an adequate animal model it is generally necessary to utilize human peripheral blood cells for studying aspects of either in vivo or in vitro HIV infection. We wish to be able to continue to elucidate many pathogenic aspects of HIV infection using human peripheral blood mononuclear cells as a model.
