Cytoplasmic granules in eosinophils
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). Eosinophils have rounder and lighter red granules than heterophils, which have dull red rod-shaped granules (middle and lower left cells). WebJul 7, 2024 · Nuclei are stained purple, and cytoplasm is stained blue to pale pink, depending on cell type. The stain differentiates the granules of different blood cells by staining them different colours. Basophils show dark blue granules and eosinophils show orange granules. The staining process is as follows: A film of blood is air dried

Each type of granulocyte and agranulocyte plays a slightly different role in fighting infection and disease. The three types of granulocytes are neutrophils, eosinophils, and basophils. The two types of agranulocytes are lymphocytes and monocytes.
WebEosinophils are the second most abundant granulocyte and account for 1–3% of circulating leukocytes and ~6% in the bone marrow. They provide host response to parasitic … 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).
