eosinophils

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.
