title: Methods to study monocyte migration induced by HIV-infected cells.
abstract: HIV-associated dementia (HAD) is a multi-factorial disease set in motion by the presence of HIV-infected cells in the brain. A characteristic feature of HAD is the infiltration of mononuclear phagocytes into the brain, which is aided by HIV-1 Tat protein and other chemokines secreted by both HIV-infected cells and uninfected cells in their vicinity. Both direct and indirect chemokine activity of HIV-1 Tat protein has been demonstrated employing purified recombinant Tat protein. However, a corroboration of a key role for Tat or other chemokines in monocyte migration, in the context of HIV-infection, has not yet been demonstrated. Here we describe methods, to measure the role of soluble factors, such as chemokines and Tat, released by HIV-infected cells or uninfected cells in their vicinity, in monocyte migration in vitro.
