The use of antisense oligodeoxynucleotides as antiviral drugs to combat HIV-1 infection may offer an alternative to traditional pharmacological therapies. We compared the effects of two 28-mer antisense phosphorothioate oligodeoxynucleotides [PS-oligo(dN)] with non-sequence-specific controls on HIV-1 replication in long-term human monocyte/macrophage and PBMC cultures. The anti-rev PS-oligo(dN) was complementary to the messenger RNA (mRNA) sequences derived from the overlapping region of the HIV-1 regulatory genes tat and rev, while anti-gag targeted the translational initiation site of the gag mRNA. In vitro cytotoxicity of the PS-oligo(dN) was evaluated at concentrations ranging from 0.1 to 10.0 microM for a period of 20 days. Cell survival was 100% at 0.1 microM, but decreased to 5% at 10.0 microM in relation to the untreated control cultures. Our data demonstrate that replication of both the T cell-tropic and macrophage-tropic HIV-1 strains in primary cells can be inhibited by PS-oligo(dN) in a sequence-specific and dose-dependent manner at concentrations achievable in vivo. However, the sequence-dependent antiviral activity of the utilized PS-oligo(dN) was limited to a window of specificity at concentrations between 0.25 and 1.0 microM.

D007700 Kinetics The rate dynamics in chemical or physical systems.
D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
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.

D000998 Antiviral Agents Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly.

D013601 T-Lymphocytes Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
