Due to the important role of monocytes/macrophages in the pathogenesis of AIDS, potential drugs with anti-HIV activity in lymphocytes must also be effective in monocytes/macrophages. For testing the efficacy of antiviral substances, monocytes/macrophages from peripheral blood were infected, respectively, with highly replicating HIV1 and HIV2 strains, thereby providing an extremely sensitive system of testing. Azidothymidine was found to inhibit both HIV types at 0.04 microgram/ml. The polysulphated polyxylan, Hoe/Bay-946 (MW 6,000 Daltons), which acts through a different mechanism and is being tested in clinical pilot studies in Germany, was also found to be effective against HIV1 and HIV2 in macrophages at concentrations of 10-50 micrograms/ml.

UI MeSH Term Description Entries
D008264 Macrophages The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D000163 Acquired Immunodeficiency Syndrome An acquired defect of cellular immunity associated with infection by the human immunodeficiency virus (HIV), a CD4-positive T-lymphocyte count under 200 cells/microliter or less than 14% of total lymphocytes, and increased susceptibility to opportunistic infections and malignant neoplasms. Clinical manifestations also include emaciation (wasting) and dementia. These elements reflect criteria for AIDS as defined by the CDC in 1993.
