A naturally occurring substance that interferes with the ability of viruses to reproduce. Interferon also boosts the immune system. There are a number of different interferons. They fall into three main classes : alpha, beta, and gamma. All are proteins (lymphokines) normally produced by the body in response to infection. The interferons have been [..]

A chemical messenger of the immune system, produced by virus-infected cells and capable of helping other cells resist the virus.

A drug used in biologic therapy to affect the division of cancer cells and slow tumor growth.

animal protein, 1957, coined in English from interfere + subatomic particle suffix -on; so called because it "interferes" with the reduplication of viruses.

One of a number of antiviral proteins that control the immune response. Interferon (IFN) alpha is secreted by a virally infected cell and strengthens the defenses of nearby uninfected cells. A manufac [..]

A substance produced by cells infected with a virus. It has the ability to stop further growth of the virus.

One of a family of proteins that are liberated by special host cells in the mammal in response to viral infection. The interferons attach to an infected cell, where they stimulate antiviral protein sy [..]

(French : interferon) A protein that is synthesized by animal cells in response to viral infection and non specifically inhibits replication of the viruses. It is found in serum almost at the onset of [..]

A protein first recognized in animals for its action in inhibiting viral replication and inducing resistance in host cells. The interferons (IFNs) are a highly conserved family of multi-functional, sp [..]

a group of proteins with a carbohydrate component, which is produced by different cell types in response to an exposure of a virus, bacterium, or parasite, that prevents replication (of the virus, bac [..]

(n) an antiviral protein produced by cells that have been invaded by a virus; inhibits replication of the virus

Interferons (IFNs) are proteins made and released by host cells in response to the presence of pathogens such as viruses, bacteria, parasites or tumor cells. They allow for communication between cells [..]

A protein produced by cells, interferon helps regulate the body's immune system, boosting activity when a threat, such as a virus, is detected. Scientists have learned that interferon helps fight [..]

A naturally produced chemical released by the body in response to viral infections. Interferon can be artificially produced and used as a form of immunotherapy.

A natural substance produced by the body in response to a virus. Interferons can stimulate the immune system to fight the growth of cancer.

A substance secreted by an infected cell which strengthens the defenses of nearby cells that are not yet infected. These substances are named differently according to their activity (interferon alpha, [..]

A naturally produced chemical released by the body in response to viral infections. Interferon can be artificially produced and used as a form of immunotherapy.A biological response modifier (a substa [..]

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 mult [..]

Interferon secreted by Leukocytes, Fibroblasts, or lymphoblasts in response to Viruses or Interferon Inducers other than Mitogens, Antigens, or allo-Antigens. They include alpha- and beta-Interferons [..]

One of the Type I Interferons produced by Fibroblasts in response to stimulation by live or inactivated Virus or by Double-Stranded RNA. It is a cytokine with antiviral, antiproliferative, and immunom [..]

The major Interferon produced by mitogenically or antigenically stimulated Lymphocytes. It is structurally different from Type I Interferon and its major activity is immunoregulation. It has been impl [..]

One of the Type I Interferons produced by peripheral Blood Leukocytes or lymphoblastoid Cells. In addition to antiviral activity, it activates Natural Killer Cells and B-Lymphocytes, and down-regulate [..]

Cytokines secreted by certain cells in response to an antigen, usually a virus. Interferon signals neighboring cells into action and inhibits the growth of malignant cells. There are three types of interferons: alpha, beta, and gamma. Laboratory-made interferons are used to treat certain cancers and opportunistic infections. See Related Term(s): An [..]

Protein produced by immune cells that helps fight viral infection. See also

A naturally produced chemical released by the body in response to viral infections. Interferon can be artificially produced and used as a form of immunotherapy.

A biological response modifier (a substance that can improve the body's natural response to infections and other diseases). Interferons interfere with the division of cancer cells and can slow tumor growth. There are several types of interferons, including interferon-alpha, -beta, and -gamma. The body normally produces these substances. They a [..]

a chemical (cytokine) produced by virus-infected cells that contributes to the cells' death by apoptosis; can be genetically engineered to create medications that impair the growth and replication of viruses and cancer cells

A protein produced naturally by the cells of our bodies. It increases the resistance of surrounding cells to attacks by viruses. One type of interferon, alpha interferon, is effective against certain [..]

a family of cytokines released in response to the presence of an infectious agent or cancer cell.

Class of proteins produced by body to neutralize an endotoxin or virus attack. Three main interferons are alpha, beta, and gamma.

A potent immune-enhancing natural protein that is produced by most vertebrates cells to fight off viral infection and cancer.  

A protein liberated by cells following exposure to viruses and other microorganisms. Interferons induce protein synthesis inhibitors that block translation of viral mRNA.

(IFN):

A family of small proteins that stimulate viral resistance in cells.

one of a number of antiviral proteins that modulate immune response. Interferon alpha (IFNa) is secreted by an infected cell and strengthens the defenses of nearby uninfected cells. A manufactured version of IFNa (trade names: Roferon, Intron A) is an HPB approved treatment for Kaposi’s sarcoma, the hepatitis B virus and the hepatitis C virus.

A substance that occurs naturally within the body and which enhances the immune system’s fight against viruses.
