Irvine, CA / Kiel, December 11, 2006 – Proteo, Inc. (OTCBB: PTEO; WKN: 925981) and its wholly-owned subsidiary Proteo Biotech AG announced today:
The team of Prof. Noel McElvaney at the Respiratory Research Division, Royal College of Surgeons in Dublin, is focused on the research in the field of inflammatory pulmonary diseases, particularly of cystic fibrosis. The team has shown that Elafin is able to abrogate lipopolysaccharide-induced production of monocyte chemotactic protein 1 in monocytes by inhibiting AP-1 and NFkappaB activation. The authors conclude that due to its selective expression at mucosal surfaces as well as in alveolar macrophages, monocytes and neutrophils, the ability of Elafin to inhibit the lipopolysaccharide signaling pathway may be important in disease states such as cystic fibrosis, pneumonia, and acute respiratory distress syndrome. The inhibition of two key inflammatory pathways confirms the importance of Elafin as a mediator of the innate immune response.

Prof. Oliver Wiedow, Chairman of the Board, Proteo, Inc.: »These results are a major breakthrough in our understanding of the anti-inflammatory properties of Elafin. In addition to the known effects of Elafin in preventing tissue degradation during inflammation this novel anti-inflammatory mechanism of Elafin may contribute to its potential efficacy in the treatment of inflammatory lung diseases in which infections play a major role.«
Elafin is a protein that is produced naturally in the skin, lung and breast, protecting the respective tissue from destruction by the immune system. Elafin’s ability to block the activity of destructive enzymes that are involved in inflammatory reactions makes it a highly promising active compound for the treatment of inflammatory lung diseases or severe reperfusion injuries occurring after heart attacks, serious injuries and organ transplantation. The excellent tolerability of Elafin in human subjects was demonstrated in a Phase I clinical single dose escalating study.
PROTEO Biotech AG, based in Kiel, Germany was founded in April 2000 and in the same year was taken over by the US-American holding company PROTEO Inc. The company researches, develops and markets compounds for biological and medical research as well as for use as pharmaceuticals. PROTEO holds the production and utilization rights for recombinant human Elafin. PROTEO intends to out-license selected indications and to establish international strategic alliances in order to open up new fields of application and for marketing. The federal state of Schleswig-Holstein funds the innovative development venture of PROTEO Biotech AG with money from the European Fund for Regional Development (EFRE).
