[Molecular genetic aspects of interferon induction and antiviral action]. 1998

S I Bazhan, and O E Belova

Interferons (IFN) are cytokines with a wide range of biological activities. The most important function of IFN is associated with the induction of host resistance to viral infections. This paper discusses the well-known experimental data and the results of the authors' theoretical studies of the regularities of type 1 interferon induction and its antiviral action. The mechanisms both of interferon gene expression and transcription regulation of IFN-stimulated genes by IFNs and viruses are analyzed. The molecular mechanisms of IFN-induced resistance and the well-known strategies acquired by viruses to overcome IFN action are discussed. The authors' analyze possible regulation by IFN of its own expression and the role of IFN- and virus-induced expression of genes of antiviral response in the development of resistance to infection.

UI	MeSH Term	Description	Entries
D007372	Interferons	Proteins secreted by vertebrate cells in response to a wide variety of inducers. They confer resistance against many different viruses, inhibit proliferation of normal and malignant cells, impede multiplication of intracellular parasites, enhance macrophage and granulocyte phagocytosis, augment natural killer cell activity, and show several other immunomodulatory functions.	Interferon

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

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.
