Cytoplasmic granules in eosinophils
WebEosinophils compose about 2-4% of white blood cells in circulating blood. This count fluctuates throughout the day, seasonally, and during menstruation. It rises in response to allergies, parasitic infections, … WebEosinophils are a prominent cell type in particular host responses such as the response to helminth infection and allergic disease. Their effector functions have been attributed to their capacity to release cationic proteins stored in cytoplasmic granules by degranulation. However, eosinophils are n …
Cytoplasmic granules in eosinophils
Did you know?
WebThe appearance of specific granules marks the progression of the promyelocyte to neutrophilic, eosinophilic, or basophilic myelocytes. Thereafter, the cell continues maturation into an amitotic cell with a segmented nucleus, capable of chemotaxis, phagocytosis, and microbial killing. WebEosinophils have round red granules and a light blue cytoplasm. Some species of dogs, such as Greyhounds, have vacuolated eosinophils (eosinophil granules lack myeloperoxidase and do not stain red). Their eosinophils can mimic monocytes but are far more vacuolated. Dog basophils have long, ribbon-like nuclei and faint purple granules.
When eosinophils are activated, they undergo cytolysis, where the breaking of the cell releases eosinophilic granules found in extracellular DNA traps. High concentrations of these DNA traps are known to cause cellular damage, as the granules they contain are responsible for the ligand-induced … See more Eosinophils, sometimes called eosinophiles or, less commonly, acidophils, are a variety of white blood cells and one of the immune system components responsible for combating multicellular parasites and … See more Following activation by an immune stimulus, eosinophils degranulate to release an array of cytotoxic granule cationic proteins that are capable of inducing tissue … See more Eosinophilia An increase in eosinophils, i.e., the presence of more than 500 eosinophils/microlitre of blood is called an eosinophilia, and is typically seen in people with a parasitic infestation of the intestines See more TH2 and ILC2 cells both express the transcription factor GATA-3, which promotes the production of TH2 cytokines, including the interleukins (ILs).

WebBlood from a Motmot (woodland bird in passerine order): Eosinophils in at least two members of this species have light blue to clear cytoplasmic vacuoles, which may be a species-unique finding (arrows).
