Mast cells should be included in the definition of leukocytes as myeloid granulocytes. Mast cells are fewer in number than other leukocytes, but mast cells regulate the recruitment and activation of other leukocytes, both directly by release of inflammatory mediators and cytokines and indirectly by downstream signaling. Mast cells often are unidentified or misidentified as basophils and are included in the total leukocyte count. Adding mast cells to the leukocyte page would be consistent with the mast cell page.
