Following tissue injury, platelets rapidly interact with the exposed extracellular matrix (ECM) of blood vessel wall and the surrounding tissues. Hyaluronan (HA) is a major polysaccharide component of the ECM and plays a significant role in regulating inflammation. Human platelets can degrade HA from the surfaces of activated endothelial cells into fragments capable of inducing immune responses by monocytes. In addition, platelets contain the enzyme hyaluronidse-2 (HYAL2), one of two major hyaluronidases that digest HA in somatic tissues. The deposition of HA increases in the inflamed tissues in several inflammatory diseases, including Inflammatory Bowel Disease (IBD). This study provides evidence …
