Pharmacological properties

INGARON® is a recombinant human interferon gamma, consists of 144 amino acid residues (a.a.), devoid of the first three amino acid residues. O. Cys-Tyr-Cys replaced by Met. Molecular weight 16.9 kDa. Obtained by microbiological synthesis in a recombinant Escherichia coli strain and purified by column chromatography. The specific antiviral activity on cells (human fibroblasts) infected with the vesicular stomatitis virus is 2 × 107 U per mg of protein. Interferon gamma (immune interferon) is the most important anti-inflammatory cytokine produced in the human body by natural killer cells, CD4Th1 cells and CD8 cytotoxic suppressor cells.

Receptors for interferon gamma have macrophages, neutrophils, natural killer cells, cytotoxic T-lymphocytes. It activates the effector functions of these cells, in particular their microbicidal, cytotoxicity, their production of cytokines, superoxide and nitroxide radicals (thereby causing the death of intracellular parasites). Interferon gamma blocks the replication of viral DNA and RNA, the synthesis of viral proteins and the assembly of mature viral particles. In this case, it causes a cytotoxic effect on virus-infected cells.

Inhibits B-cell response to interleukin-4, inhibits IgE production and expression of CB23 antigen. It is an inducer of apoptosis of differentiated B-cells, giving rise to autoreactive clones. Cancels the suppressive effect of interleukin-4 on interleukin-2-dependent proliferation and generation of activated killer lymphokines. It activates the production of proteins of the acute phase of inflammation, enhances the expression of genes C2 and C4 components of the complement system.

Unlike other interferons, it increases the expression of MHC antigens of both class I and II on different cells, and induces the expression of these molecules even on those cells that do not express them constitutively. This increases the efficiency of the presentation of antigens and the ability of their recognition by T-lymphocytes.

Interferon gamma blocks the synthesis of β –TGF, which is responsible for the development of pulmonary and liver fibrosis.
