N2 - OTK18 was isolated by mRNA differential display of human monocyte-derived macrophages (MDM) infected with human immunodeficiency virus type one (HIV-1). Northern blot and real-time reverse transcription polymerase chain reaction showed low levels of OTK18 expression in human tissue, which markedly increased during advanced HIV-1 encephalitis (HIVE). Immunocytochemistry, using rabbit polyclonal antisera, showed OTK18 localized to brain mononuclear phagocytes (MP) in moderate to severe HIV-1 encephalitis. OTK18 expression was selective and not found in HIV-1-infected brain tissue with limited neuropathological abnormalities, nor in cytomegalovirus encephalitis, multiple sclerosis, Alzheimer's disease, or uninfected control brains. Thus, OTK18 expression in brain mononuclear phagocytes is a signature for advanced HIV-1 encephalitis.
