Explanation:
Detailed explanation-1: -Basophils are the least common of the leukocytes, and release histamine during inflammation.
Detailed explanation-2: -Histamine is stored in the granules of mast cells, basophils, platelets. This histamine is released from these cells by the stimuli inducing acute inflammation, anaphylatoxins, and histamine releasing factors.
Detailed explanation-3: -Once activated, mast cells secrete numerous vasoactive and pro-inflammatory mediators [37-42]. These include pre-formed molecules such as histamine, serotonin, TNF, kinins and proteases stored in secretory granules.
