Any of a group of glycoproteins, produced by the immune system, that prevent viral replication in infected cells
Protein produced by cells that induces immunity to viral infection Various types of this substance are used in cancer treatment
a glycoprotein produced by cell s which mobilise the T lymphocytes to inhibit viruses and the growth of cancer cells
a chemical substance that is produced by your body to fight against viruses that cause disease (interfere + -on chemical compound). Any of several related proteins produced by all vertebrates and possibly some invertebrates. They play an important role in resistance to infection. The body's most rapidly produced and important defense against viruses, they can also combat bacteria and parasites (see parasitism), inhibit cell division, and promote or impede cell differentiation. Interferon's effect is indirect it reacts with susceptible cells, which then resist virus multiplication in contrast to antibodies, which act by combining directly with a specific virus. Various types of interferons are distinguished by their characteristics as proteins and by which cells produce them. Some are now produced by genetic engineering. Initial hopes that interferon would be a wonder drug for a wide variety of diseases were deflated by its serious side effects, but a few rare conditions respond to it
A type of cytokine protein produced by cells Interferon helps regulate the bodys immune system
an antiviral protein produced by cells that have been invaded by a virus; inhibits replication of the virus
a class of protein produced in miniscule amounts by infected cells that appear to boost the immune system and its ability to fight cancer
A naturally occurring class of proteins used to simulate the immune system to fight hepatitis and certain forms of cancer When used to fight hepatitis C, individual responses to treatment may be divided into three broad categories: (1) sustained responders who rid the virus from their blood and have their serum liver enzymes return to normal even six months after therapy is stopped; (2) nonresponders, who do not show a disappearance of viral RNA levels from the blood and do not have their serum liver enzymes return to normal; and (3) partial responders, who drop their viral levels and liver enzymes on treatment but fail to maintain these successes once treatment is discontinued
a biological response modifier that stimulates the growth of certain disease-fighting blood cells in the immune system
(INF) - A class of small glycoproteins (one of a group of protein-carbohydrate compounds) that exert antiviral activity at least in homologous cells (cells that look alike)
A protein produced by the immune system in response to attack by a virus that helps protect other healthy cells from attack
The name given to a group of proteins that the body produces naturally in response to viral infections and other stimuli Interferon increases the activity of natural killer cells (types of lymphocytes that are part of the body's immune system)
A protein liberated by cells following exposure to viruses and other microorganisms Interferons induce protein synthesis inhibitors that block translation of viral mRNA
A cytokine (or hormone) which is produced normally in response to a viral infection Produced by genetic engineering techniques, synthetic interferon is given as treatment for Myeloma It is used primarily as maintenance therapy in the plateau phase to block any re-growth of Myeloma and thus delays or prevents relapse
A group of immune system proteins, produced and released by cells infected by a virus
a protein produced in organisms infected by viruses, and effective at protecting those organisms from other virus infections Interferons exert virus-nonspecific but host-specific antiviral activity by inducing the transcription of cellular genes coding for antiviral proteins that selectively inhibit the synthesis of viral DNA and proteins Interferons also have immunoregulatory functions Production of interferon can be stimulated by viral infection, especially by the presence of double stranded RNA, by intracellular parasites, by protozoa, and by bacteria and bacterial products Interferons have been divided into three distinct types (α, β, and γ) associated with specific producer cells and functions, but all animal cells are capable of producing interferons, and certain producer cells (leukocytes and fibroblasts) produce more than one type (both α and β)
