Official title
Mononuclear Cell Phenotyping in Normal Children
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to learn more about some of the immune cells in the blood (CD4 cells, for example) of healthy children in order to better understand the differences in the blood cells of children infected with HIV. Because children's bodies are still developing, their cells are different from those of adults, and their bodies respond differently to infections such as HIV. In order to understand how immune cells grow and mature so that they can fight HIV, it is important to see how these cells behave in normal children.
