Summary of Applications of Orally Administered Interferon in Animal and Human Health
The Interferons (IFN) are a group of natural proteins that are produced by mammalian cells in response to viral infection and other stimuli. They were first described in 1957, and were named for their ability to interfere with viral and tumor cell replication. There are three main types of interferon:
- Interferons beta and alpha—produced mainly by white blood cells and certain connective tissue cells called fibroblasts.
- Interferon gamma—produced primarily by activated T cells—is a naturally-occurring substance in the body that promotes inflammation. In many ways, interferon beta and interferon gamma work to counteract each other.
- A distinct group of cytokines (molecules that cause movement of immune cells and promote immunity) exhibiting pleiotropic (multiple) activities categorized as antiviral, antiproliferative and immunomodulatory.
- Potent mediators in the host defense mechanism and homeostasis, modulating both the innate and adaptive immune responses.
- Small (20-25k daltons) proteins induced in vertebrate cells in response to viruses, bacteria, protozoa, certain cytokines, mitogens, natural and synthetic double-stranded RNA.
- Mediators of biological activities by binding to receptors present on the surface of target cells.
Low dose oral IFN alpha has been tested in:
- 68 human clinical trials
- 100+ clinical trials in dogs, cats, horses, swine, cattle, poultry, fish, & rodents.
Oral IFN is Safe and Often Beneficial in Humans:
- Aphthous Stomatitis (n=3 trials)
- Behcet’s Disease (n=1)
- Cancer (various) or Chemotherapy-induced Stomatitis (n=4)
- Chronic Fatigue Syndrome (n=1)
- Common Cold (n=5)
- Fibromyalgia Syndrome (n=2)
- Healthy Volunteers (n=2)
- Hepatitis B (n=7)
- Hepatitis C (n=6)
- HIV treatment (n=20)
- HIV-related Xerostomia (n=1)
- Idiopathic Pulmonary Fibrosis (n=1)
- Influenza (n=1)
- Miscellaneous Liver Diseases (n=1)
- Myeloproliferative Diseases (n=2)
- Oral Warts in HIV+ Patients (n=3)
- Sjögren’s Syndrome (n=8)
