Description
Calprotectin is an important calcium signalling protein involved in wound healing. A complex of both MRP14 and MRP8, calprotectin plays a role in vascular inflammation and leukocyte recruitment. This 36kDA complex is a calcium and zinc- binding protein that represents 60% of cytosolic proteins of granulocytes. Classed as a damage associated molecular pattern marker it displays antimicrobial protective properties.
Extracellular release of calprotectin during cell damage/stress can be used as a marker for intestinal inflammation. There is growing evidence that faecal calprotectin correlates with mucosal disease activity which can be utilised as a monitoring response to relapse and treatments in inflammatory bowel disease. Measuring the concentration of calprotectin in faeces is an indirect measure of neutrophil infiltrate in the bowel mucosa.
