Fixing cells infected by HIV and stained for immunofluorescence on a glass slide. Human macrophages, immune cells, were extracted from the blood of healthy donors. These were then put into culture and co-infected with HIV and Mycobacterium tuberculosis, the agent responsible for tuberculosis. The infected cells were stained with visible fluorescent antibodies which specifically recognize HIV. These immunofluorescence experiments were designed to monitor the development of the HIV infection and improve our understanding of the mechanisms behind the aggravation of this infection induced by tuberculosis.
