a large cell that occurs esp in connective tissue and has basophilic granules containing substances (as histamine and heparin) which mediate allergic reactions
A cell found in connective tissue that contains numerous basophilic granules and releases substances such as heparin and histamine in response to injury or inflammation of bodily tissues
A cell that is derived from the pluripotential lymphohematopoietic stem cell It traverses the blood in such small numbers that it is not recognized as a blood cell It enters the tissues and in those sites is apparent because of its large and numerous granules, which when stained in slides of tissue samples have a characteristic deep blue-purple color In allergic reactions, it is the source of histamine and other chemicals that causes many of the symptoms of allergy
A specialized cell found in tissues It causes allergic reactions when activated by allergens that bind to IgE antibodies on the cell surface Activation of the cell is followed by release of histamine and other substances that cause symptoms of allergy
An immune system cell which attaches to antibodies and is located in the tissue that lines the nose, bronchial tubes, gastrointestinal tract, and the skin
Type of cell that is widely distributed throughout the body and particularly prevalent in neurofibroma tissue Mast cells secrete substances that may affect the behavior of other cells nearby, including those involved in the development of neurofibromas
Mast cells play an important role in the body's allergic response Mast cells are present in most body tissues, but are particularly numerous in connective tissue, such as the dermis (innermost layer) of skin In an allergic response, an allergen stimulates the release of antibodies, which attach themselves to mast cells Following subsequent allergen exposure, the mast cells release substances such as histamine (a chemical responsible for allergic symptoms) into the tissue
A bone marrow-derived cell present in a variety of tissues that resembles peripheral blood-borne basophils and contains an Fc receptor for IgE It undergoes IgE-mediated degranulation (See 707)
a basophil (a type of granular white blood cell) that has left the bloodstream and entered a tissue Mast cells release histamine and heparin, chemicals which mediate allergic reactions
An immune system cell filled with granules of inflammatory chemicals such as histamine This cell is believed to play a leading role in generating the symptoms of allergy
a large connective tissue cell that contains histamine and heparin and serotonin which are released in allergic reactions or in response to injury or inflammation

cells, which synthesize and store histamines, found in most body tissues, particularly just below the epithelial surfaces, serous cavities and around blood vessels In an allergic response, an allergen stimulates the release of antibodies, which attach themselves to mast cells

cells, which synthesize and store histamines, found in most body tissues In an allergic response, an allergen stimulates the release of antibodies, which attach themselves to mast cells
Cells present close to body surfaces (such as the skin and intestines), which produce and release chemicals-for instance, histamine-which then produce allergic symptoms
