CEL-SCI'S CEL-1000 Shown To Significantly Enhance Immune Response Against Avian Flu Antigen In Animals

CEL-SCI CORPORATION (Amex: CVM) announces that CEL-1000 increased the immune response against H5 avian influenza antigen in combination with MAS-1, a water-in-oil adjuvant delivery system. These findings were presented on May 23, 2007 by Dr. Daniel Zimmerman, Senior Vice President of Research, Cellular Immunology at CEL-SCI at the American Society of Microbiologists 107th annual general meeting in Toronto, Canada. This new finding with CEL-1000 may have broad application for the enhancement of immune responses by individuals who have a poor immune response to vaccinations. It also has application for antigen sparing (reducing the amount/dose of antigen required for protective immunity), and to biodefense and pandemic settings for anti-infectious vaccines. CEL-1000 has previously been shown to increase the antigenicity of hepatitis B virus (HBV). In challenge studies, CEL-1000 has also previously been shown to protect animals against infection against viruses and unrelated diseases, specifically herpes simplex virus, viral encephalitis and malaria. CEL-1000 appears to activate innate (very early stage) and Th1 type (cellular) immune responses to induce a broad-spectrum protection against infection in animal models. The innate immune system is generally accepted to be the first line of defense against infectious agents. CEL-1000, derived from the beta chain of human MHC-II, is a modified version of a human immune-based protein known to bind to both human and mouse immune cells and appears to act by enhancing the host's protective immune response.
