eosinophils

(noun)

a type of white blood cell used to fight parasitic infection

Examples of eosinophils in the following topics:

  • Types of Adaptive Immunity

    • Humoral immunity refers to the component of the adaptive immune response that is caused by B cells, antibodies, and type 2 helper T cells (Th2), as well as circulating mast cells and eosinophils to a lesser extent.
    • Mast cells and eosinophils are considered part of the humoral immune system because they can be sensitized towards certain antigens through circulating immunoglobin E (IgE), a specific type of antibody produced by B cells.
    • IgE binds to the mast cells and eosinophils when an antigen is detected, using a type of Fc receptor on the mast cell or eosinophil that has a high-binding affinity with IgE.
  • Innate Immune Response

    • In this compound light micrograph, purple-stained neutrophil (upper left) and eosinophil (lower right) are white blood cells that float among red blood cells in this blood smear.
    • Eosinophils play a variety of roles in the immune response.
  • Cystitis

    • Eosinophilic cystitis (EC) is a rare form of cystitis that is diagnosed via biopsy.
    • In these cases, the bladder wall is infiltrated with a high number of eosinophils.
    • Differentiate among the distinct types of cystitis: traumatic, interstitial, eosinophilic, hemorrhagic cystitis, and cystitis cystica, recognizing their causes and risk factors
  • Distribution and Importance of Parasitic Worms

    • The study demonstrates that immune system cells, eosinophils, that are present in fat tissue play a role in the prevention of insulin resistance via secretion of interleukin 4.
    • The study showed that parasitic worm infection results in an increase in eosinophils, thus, promoting control of glucose maintenance .
  • Types of WBCs

    • The different types of white blood cells (leukocytes) include neutrophils, basophils, eosinophils, lymphocytes, monocytes, and macrophages.
    • Eosinophils primarily deal with parasitic infections.
    • From left to right, a neutrophil, an eosinophil, and a basophil.
  • White Blood Cells

    • One of the two main groups are the granulocytes, which contain granules in their cytoplasm, and include the neutrophils, eosinophils, and basophils ( a).
    • (a) Granulocytes (neutrophils, eosinophils and basophils) are characterized by a lobed nucleus and granular inclusions in the cytoplasm.
  • Pathogen Recognition

    • An eosinophil is a leukocyte that works with other eosinophils to surround a parasite.
    • Neutrophils and eosinophils are particularly important leukocytes that engulf large pathogens, such as bacteria and fungi.
    • Eosinophils and basophils produce additional inflammatory mediators to recruit more leukocytes.
  • The Role of Blood in the Body

    • White blood cells (including neutrophils, monocytes, lymphocytes, eosinophils, and basophils) are involved in the immune response.
  • WBC Function

    • This process is performed primarily by mast cells, eosinophils, basophils, and NK cells.
  • X-Ray Studies of the GI Tract

    • This x-ray after barium swallow shows the effects of eosinophilic esophagitis.
