Flexi Says: Inflammation is one way the body reacts to infections or injuries. Inflammation is caused by chemicals that are released when the skin or other tissues are damaged. The chemicals cause nearby blood vessels to dilate, or expand. Mast cells play a central role in inflammatory and immediate allergic reactions since they are able to release potent inflammatory mediators including histamine, proteases, chemotactic factors and cytokines in injured or infected tissue sites.
