mastocyte

mast cell

a connective tissue cell that contains coarse, basophilic, metachromatic secretory granules that contain, among other pharmacologic agents, heparin, histamine, and eosinophilic chemotactic factor. These cells are involved in immediate hypersensitivity reactions and play a role in the regulation of the composition of ground substance.

contortus have reported cellular infiltrations in the mucosa and regional lymph nodes, increases in T CD4+, T CD8+, T gamma delta ([gamma][delta]) and B lymphocytes, eosinophils and mastocytes [5, 11, 17, 75].
The hyperplasia of mastocytes in the abomasum mucosa is associated mainly with the presence of adult parasites and is greater in re-infections [10, 42], requiring a continuous stimulation on the part of parasitic antigens [4, 10].
Through the release of specific cytokines from LC, the homing T lymphocytes are activated very rapidly because they are ready on site (in the skin) and they activate B cells with subsequent overproduction of IgE binding not only to LC but also to mastocytes and basophils, leading to the release of histamine, prostaglandins, and leukotrienes (early phase reaction) 15 to 60 minutes after contact with airborne allergens.
