Granulocytes

Group of white blood cells, white granule cells, relatively large, with a strongly segmented nucleus and neutrophilic, basophilic or eosinophilic granules (granula) in the cytoplasm.

White blood cells (leukocytes) with cell plasma granules that can be stained and are produced by the body's own mediators ( see or attracted to the site of inflammation by bacterial substances (leukotaxis), take up foreign bodies, bacteria, fungi or destroyed tissue there (phagocytosis) and kill germs by enzymes located mainly in the granula with formation of hydrogen peroxide.

There are three groups of granulocytes:

1. basophilic granulocytes whose granules can be stained with basic dyes; granulocyte content up to 1%;

2. eosinophilic granulocytes whose granules can be stained with eosin or acid dyes and whose proportion (normally 2-4%) in the blood increases, e.g. in allergic reactions; are capable of phagocytosis of blood immune complexes;

3. neutrophilic granulocytes, the most common form of granulocytes (in differential blood count up to 70%) with granules stainable by neutral, basic and acid dyes and with a strongly segmented core.
