a white blood cell that is involved in some allergic processes (asthma, allergic rhinitis and hay fever).

A type of cell that is often found in nasal mucus that identifies allergy.

a type of white-blood cell involved in allergic reactions and are thought to play a role in combating cancer.

a type of white blood cell characterized by granular cytoplasm readily stained by eosin

Pronounced "EE-Oh-SIN' -oh-fill": A type of white blood cell that normally combat moulds, fungi (funguses) worms, toxins, and a few drugs, but that in Churg-Strauss Syndrome patients multiply beyond their normal numbers and invade (infiltrate) lung tissue and blood vessels.

A type of white blood cell that offers important defense against allergic reactions.

A white blood cell that increases in number as a result of certain parasite infections and allergic diseases.

A type of white blood cell that participates in allergic reactions and helps to fight certain parasitic infections.

A granular leukocyte, the granules of which have an affinity for the acid dye of Wright’s stain (eosin). The granules are large, round, uniform in size, red-orange in color and are shiny and refractile.

polymorphonuclear leukocyte containing eosin-staining cytoplasmic granules; associated with parasites and asthma.

A polynucleated granulocyte containing granules filled with hydrolytic enzymes.

A granulated white blood cell with a nucleus that has one, two or more lobes connected by a thread of chromatin cytoplasm with coarse, uniform eosinophilic granules. 1-3% of total white blood cells. Increase in number with allergy and infection.

An inflammatory cell in the blood that is attracted to the site of allergic reactions and participates in allergic inflammation.

A type of white cell that responds to both allergic reactions and foreign bacteria.

a leukocyte readily stained with eosin

Component cell of the body's immune system. Contained/formed within bone marrow.

A leukocyte capable of phagocytosis and serves in mitigating allergic responses.

Amoeba-like scavenger leukocyte (white blood cell) that disposes of cellular debris; often involved in allergic responses

White blood cell with large eosinophilic granules with multiple inflammatory roles.

"leukocyte" characterized by a nucleus with 2 lobes, and by the fact that it contains large granulations (grains) which have a pronounced affinity for acid stains (low pH), such as eosin.

A granular leucocyte containing a bilobed nucleus and numerous eosinophilic granuoles. EM microscopy shows that eosinophil granuoles contain a semi-crystaline core called a crystalloid. These cells are thought to play a role in down regulating the inflamation reponse by degrading histamine but may also directly attack some parasitic organisms.

A white cell of the category known as granulocytes. These cells contain numerous dense granules in their cytoplasm that comprise a battery of highly active digestive chemicals and toxins. Their chief role is thought to be in combatting large parasites, although occasionally their activity may be triggered by other agents, potentially leading to damage of normal tissues (see eosinophilia myalgia syndrome).

Circulating white blood cell; a type of granulocyte; often involved in allergic reactions.

A type of white blood cell that is specifically involved in allergic reactions (IgE-Mediated), and also seems to be involved in some parasitic infections.

Type of white blood cell that kills parasites and plays a role in allergic reactions.

A specific type of immune cell that can cause tissue damage in the late phase of an allergic reaction.

a leukocyte (blood cell) that can accept eosin stain.

A type of white cell that responds to allergic reactions as well as foreign bacteria.

A type of white blood cell whose major useful role seems to be in protecting against parasitic infections. It is also associated, however, with the inflammation that is at the root of asthma. People with asthma tend to have more eosinophils in their blood and, in addition, have an unusual number of eosinophils "migrate" into their lungs. It is still not entirely clear whether eosinophils cause some of the problems that asthmatics experience, or whether they are just associated with the process without doing damage themselves.

(ee'-o-SIHN-o-fihl) A type of granulated white blood cell characterized by a cytoplasm that accepts the eosin stain.

A type of white blood cell, called granulocyte, that can digest microorganisms. The granules can be stained by the acid dye, eosin, for microscopic examination.

A white blood cell that contains granules filled with chemicals damaging to parasites, and enzymes that damp down inflammatory reactions.

A white blood cell readily stained with eosin that is often present in high numbers in patients with allergic disorders.

A type of white blood cell. Eosinophils are one type of granulocyte.

An eosinophil is a variety of white blood cell distinguished by the presence in its cytoplasm of coarse granules; its function is poorly understood, but it is known to be capable of ingesting foreign particles, is present in large numbers in lining or covering surfaces of the body, and is involved in allergic responses.

A polymorphonuclear leukocyte with large eosinophilic (i.e. red) cytoplasmic granules.

A type of white blood cell that usually comprises 5% of all white blood cells in the blood. Eosinophils are found in increased numbers in chronic rhinosinusitis, nasal polyps and asthma. They contribute to inflammation by production of inflammatory mediators, such as leukotriene C4.

A type of white blood cell important in modulating immune responses. High levels of these cells signal the presence of asthma or an ongoing allergic reaction.

A type of white blood cell involved in inflammation and allergic reactions. It is also important in parasite infections.

A type of leukocyte (white blood cell) with coarse round granules of uniform size within its cytoplasm and typically a two-lobed nucleus. Eosinophils normally constitute 1 to 3% of the peripheral blood leukocytes.The eosinophil count in the blood often rises above the normal range with allergic reactions and parasitic infections.

A white blood cell that can increase in numbers for many reasons but specifically in any parasitic disease such as heartworms.

A type of white blood cell, called granulocyte, that can digest infectious agents.

Granuloycte; granules of this type of white blood cell take up the dye eosin

One of white blood cell called granulocytes that can digest microorganisms.

The eosinophils, ordinarily about 2% of the granulocyte count (60 to 75% of the white blood cells), increase in number in the presence of allergic disorders and parasitic infestations.
