VCU study shows hormone-like molecule kills cells that cause inflammation in allergic disease
...an, mast cells are packed with granules containing histamine
and are present in nearly all tissues except blood. When mast cells are activated, inflammatory substances such as histamine, heparin and a number of cytokines are rapidly released into the tissues and blood, promoting an allergic reaction. Mast cel...
