Crohn's Disease - Inflammation and Microbial Proteolytic Activity

Crohn's Disease of Both Small and Large Intestine

This study postulates that altered microbiota associated with areas of mucosal inflammation in CD, can be characterized by an increased proteolytic profile. This is clinically important as it may be possible to modulate the proteolytic activity of the CD-associated bacteria by using other bacteria that produce protease inhibitors, such as serpins.
