商品名：Virbagen omega
Recombinant omega interferon contained in Virbagen omega is produced by silkworms previously inoculated with interferon-recombinant baculovirus. It allows the production of pure interferon. Omega interferon of feline origin, produced by genetic engineering, is a Type 1 interferon closely related to alpha interferon. The exact mechanism of action of interferon omega is not understood, but it may enhance nonspecific defenses in dogs and cats. Interferon does not act directly and specifically on the pathogenic virus but exerts its effect by inhibition of the internal synthesis mechanisms of the infected cells. After injection it has a half-life of 1.4 hours in dogs and 1.7 hours in cats. It is bound to receptors in cells infected by virus. There are multiple interferons available for human us
Interferon is used to stimulate the immune system in patients. It has been used to stimulate immune cells in dogs with parvovirus and in cats with feline retrovirus (feline leukemia virus [FeLV] and feline immunodeficiency virus [FIV]). It has not been effective for FIP in cats. Human interferon alpha, orally, has improved clinical signs in cats with FIV.
