A white blood cell with granules that can be stained by eosin dyes. Eosinophils participate in allergic and hypersensitivity reactions.
Polymorphonuclear leukocytes made in the bone marrow. They circulate in the blood for a number of hours (three to eight) and then migrate into the tissue where they reside. They kill parasites too large to be phagocytized by secreting substances that kill the parasites (hookworms, trichinosis, etc.). They also inhibit histamine release from mast cells and secrete chemicals that neutralize histamine. Allergy causes an increase in eosinophils. GM-CSF stimulates eosinophil production.
Granulocytes that constitute one of the two main types of leukocytes in the blood.
A type of cell that can be stained with eosin.
White blood cell readily stained with eosin. Eosinophils, normally about 1-3% of the total white blood cell count, are believed to function in allergic responses and in resisting some infections.
A variety of white blood cell distinguished by the presence in its cytoplasm of coarse granules that stain orange red with Romanovsky stains. The function of the eosinophil is poorly understood, but it is capable of ingesting foreign particles, is present in large numbers in lining or covering surfaces within the body, and is involved in allergic responses. There are normally 0.04-0.4 x 10′ eosinophils per liter of blood.
Any cell in the body with granules in its substance that stain easily with the dye, eosin. Granulocytes which form about 2 per cent of the white cells of the blood are eosinophils.
A white blood cell with a lobed nucleus and cytoplasmic granules that stain red with Wright’s stain. Eosinophils make up 1% to 3% of the white cell count. They contribute to the destruction of parasites and to allergic reactions by releasing chemical mediators such as histamine.
A segmented white blood cell characterized by sizable orange-red granules, which exhibits heightened levels in reaction to parasitic infections and allergic responses.
Eosinophils are a type of white blood cell (leukocyte) that serve a significant role in allergic responses and combatting parasitic infections.
A type of white blood cell with a strong affinity for eosin. The normal proportion of these cells significantly rises when the body is infested with parasites or in certain allergic conditions.
