    摘要: Acemannan has now been discovered to be a potent inducer of Interleukin 1 (Il-1) and prostaglandin E.sub.2 (PGE.sub.2) production by human peripheral blood adherent cells in culture. Il-1 has been shown to be an important macrophage product and is associated with influencing the activity and production of T lymphocytes, fibroblasts, B lymphocytes and endothelial cells. Acemannan has no demonstrated toxicity, and acts as an adjuvant and immunoenhancer. Administration of an amount of acemannan sufficient to stimulate monocytes and macrophages not only produces Il-1 and PGE.sub.2 but also stimulates phagocytosis, increases antibody production, enhances antiviral activity in the serum and, in those patients with AIDS/ARC, produces defective HIV virus.Acemannan has been shown to affect the rate of virus production in viral vaccine master seed cultures by accelerating the rate of viral replication. In addition, acemannan is a potent adjuvant to viral vaccines in chickens. Acemannan has also shown specific antitumor activity against sarcoid tumors in horses.

    摘要: The present invention relates to compounds and methods for the prevention or treatment of infections by negative strand RNA viruses, such as influenza virus and measles virus, wherein said compounds delay or inhibit viral replication by modulating the level or activity of a polypeptide involved in the synthesis or degradation of sphingosine-1-phosphate (S1P) in a cell, tissue, or subject. The methods involve administration of one or more compounds which modulate the level of gene expression, where the gene encodes a polypeptide involved in regulating the metabolic level of S1P, or modulate the level or activity of a polypeptide involved in regulating the metabolic level of S1P, such as sphingosine kinase (SK) and S1P lyase (SPL). Exemplary methods are directed towards reducing the level of SW by reducing the level or activity of one or more SKs, increasing the level or activity of one or more SPLs, or a combination of both steps.
