Question: Who Makes Interferon Alfa2b?

Who manufactures interferon?

Two drug companies manufacture pegylated interferon.

Roche Products Ltd make Pegasys (interferon alpha 2A) and MSD make PegIntron (interferon alpha 2B)..

What produces interferon alpha?

Alpha interferon is produced by white blood cells other than lymphocytes, beta interferon by fibroblasts, and gamma interferon by natural killer cells and cytotoxic T lymphocytes (killer T cells). All interferons inhibit viral replication by interfering with the transcription of viral nucleic acid.

Do humans have interferon?

Recombinant Analogs of Endogeneous Human Proteins (Interferons, Cytokines, Enzymes) Interferons (IFNs) are types of cytokines that occur naturally in the body. While there are three major types of IFNs—IFN alpha, IFN beta, and IFN gamma, IFN alpha is the type most widely used in cancer treatment [2].

What does interferon do in the body?

Interferons are proteins that are part of your natural defenses. They tell your immune system that germs or cancer cells are in your body. And they trigger killer immune cells to fight those invaders. Interferons got their name because they “interfere” with viruses and keep them from multiplying.

Where does interferon come from?

Type I interferon (IFN-alpha and IFN-beta) is secreted by virus-infected cells while type II, immune or gamma interferon (IFN-gamma) is mainly secreted by T cells, natural killer (NK) cells and macrophages.

What are the side effects of interferon?

These side effects can include:swelling or other reactions at the injection site.flu-like symptoms such as headache, tiredness, and weakness.chills.fever.trouble sleeping.nausea.vomiting.diarrhea.More items…

Can interferon cure HPV?

Interferons have been used successfully in treating patients with genital warts induced by low-risk HPV types but show mixed results in treating low-grade lesions and cancers induced by high-risk HPVs (zur Hausen 2002).

How is interferon manufactured?

In general, type I interferons are produced when the body recognizes a virus that has invaded it. They are produced by fibroblasts and monocytes. However, the production of type I IFN-α is inhibited by another cytokine known as Interleukin-10.

Does interferon kill viruses?

Interferons do not directly kill viral or cancerous cells; they boost the immune system response and reduce the growth of cancer cells by regulating the action of several genes that control the secretion of numerous cellular proteins that affect growth.

Is interferon an antiviral?

The interferons (IFNs) are glycoproteins with strong antiviral activities that represent one of the first lines of host defense against invading pathogens. These proteins are classified into three groups, Type I, II and III IFNs, based on the structure of their receptors on the cell surface.

What does interferon mean?

Listen to pronunciation. (in-ter-FEER-on) A natural substance that helps the body’s immune system fight infection and other diseases, such as cancer. Interferons are made in the body by white blood cells and other cells, but they can also be made in the laboratory to use as treatments for different diseases.

Can Interferon be taken orally?

Interferon-alpha (IFN-alpha) given orally has biological activity in humans and other animals. The dose providing the most benefit delivers IFN-alpha to the oral mucosa in a concentration (10(2)-10(3) IU), similar to that naturally produced in the nasal secretions during respiratory infections.
