Pharmacological properties / immunological and biological properties.
LIASTENUM® belongs to naturally derived immunomodulators with a broad spectrum of action. It represents fragments of the cell wall of lactobacilli. LIASTENUM® stimulates macrophage function and normalizes the number of T-lymphocytes. LIASTENUM® activates cells of the monocyte-macrophage lineage, enhances phagocytosis, increases lysosomal enzyme activity, production of reactive oxygen species, and strengthens the cytotoxic effect of macrophages against cells infected with viruses and bacteria, as well as tumor cells. The medicinal product enhances cytokine synthesis, particularly interleukin-1. LIASTENUM® increases cytotoxic activity of natural killer cells. Immunomodulating activity of the medicinal product is also manifested by preservation of thymus endocrine function and reduction of circulating immune complexes. LIASTENUM® promotes stimulation of leukopoiesis, exhibits weak antimetastatic and antitumor effects, and reduces adverse effects of chemotherapy and radiation therapy. The drug has no embryotoxic, mutagenic, or teratogenic effects.
