November 9, 2007 — Researchers say that the integrin-transforming growth-factor beta axis is involved in the development of fibrosis and that by blocking integrin beta 6, pulmonary toxicity can be prevented and possibly even reversed. The promising preliminary results testing the new monoclonal antibody being developed by Biogen Idec were presented at plenary here at the 49th annual meeting of the American Society for Therapeutic Radiology and Oncology.
