Isolation, propagation, and HIV-1 infection of monocyte-derived macrophages and recovery of virus from brain and cerebrospinal fluid.
Mononuclear phagocytes (MP: monocytes, dendritic cells, and tissue macrophages) are host cells for the human immunodeficiency viruses types 1 and 2. MPs are both the first lines of defense and vehicles for viral dissemination in the infected human host. Viral infection of MP can affect the disease directly during interstitial pneumonitis and HIV encephalitis. Both revolve around MP secretions of immune regulatory and neurotoxic factors. Clearly, laboratory models that mimic disease need to include primary human MP infected with viral isolates obtained from diseased tissues. Over the past two decades our laboratory has developed state-of-the-art methods for isolation and propagation of monocytes from peripheral blood. This technology directly supports work at the University of Nebraska Medical Center as well as research performed throughout the United States, including the laboratories of Drs. Mario Stevenson, William Tyor, David Volsky, Loyda Melendez, and Mary-Jane Potash, among others. The importance of these cells as targets for virus and reservoirs of persistent infection are discussed.
