Summary
This study aims to learn more about how HIV infects cells and affects the immune system by collecting blood samples from up to 2,419 adults, both with and without HIV. Researchers will analyze these samples to compare genetic and protein differences. The goal is to better understand the disease, not to test a new treatment.
