Detailed explanation-1: -Mast cells are located in tissues, mainly in mucosa, and their granules contain heparin, serotonin, and histamine. They may also release a variety of cytokines that enhance the inflammatory process, especially during the early events. These cells are involved in allergic and viral processes.

Detailed explanation-2: -Innate Immunity Many of the cells in the innate immune system (such as dendritic cells, macrophages, mast cells, neutrophils, basophils and eosinophils) produce cytokines or interact with other cells directly in order to activate the adaptive immune system.

Detailed explanation-3: -Mast cells are immune cells of the myeloid lineage and are present in connective tissues throughout the body. The activation and degranulation of mast cells significantly modulates many aspects of physiological and pathological conditions in various settings.

Detailed explanation-4: -Mast cells are important for both innate and adaptive immunity in tissues that are in close contact with the environment, i.e. the skin, the airways and the lung, and the lining of the intestine.
