... Cells of the mononuclear phagocyte system represent the predominant cell population expressing human immunodeficiency virus-1 (HIV-1) in most tissues. Unlike CD4+ T-lymphocytes, monocytes and macrophages are relatively resistant to the cytopathic effect of HIV-1 and, thus, serve as a reservoir for t ...
