New Treatment Strategy for Crohn’s Disease Shows Early Promise

A preliminary study reports that enhancing the body’s innate immunity can improve symptoms of Crohn’s disease in 80 percent of patients with moderate to severe forms of the debilitating, inflammatory gastrointestinal disorder. Crohn’s disease is a chronic, lifelong condition, which affects about half a million people in the United States. Until now, the disease has been thought to result from an overactive immune system, and therapies have attempted to suppress, rather than enhance, the immune response. Therapies that suppress immunity improve symptoms in many Crohn’s disease patients, but researchers are looking for alternative treatments to help those who don’t respond.

Anti-microbial peptide may improve cancer vaccines

Researchers have discovered that a molecule best known for its anti-microbial properties also has the ability to activate key cells in the immune response. This newly discovered function suggests the molecule, a peptide called ?-defensin 2, may be useful in the development of more effective cancer vaccines.
