There are four types of granulocytes (full name polymorphonuclear granulocytes): [3] Basophils; Eosinophils; Neutrophils; Mast cells; Except for the mast cells, their names are derived from their staining characteristics; for example, the most abundant granulocyte is the neutrophil granulocyte, which has neutrally staining cytoplasmic granules. [4]
Steady state granulopoiesis is a term used to describe the normal daily production of granulocytes. Granulocytes are short lived cells (their lifespan is between 6 and 8 hours) with a high cell turnover. The number of granulocytes produced every day is between 5 and 10 x 10 10. [13] The master regulator of steady state granulopoiesis is C/EBPα.
A group of leukocytes, called granulocytes, are white blood cells containing enzyme granules that play a significant role in the immune system. Granulocytes include neutrophils, eosinophils, and basophils which attack bacteria or parasites, and respond to allergens. Each type of granulocyte contains enzymes and chemicals tailored to its ...
Basophils are the least common type of granulocyte, representing about 0.5% to 1% of circulating white blood cells. [1] They are the largest type of granulocyte. They are responsible for inflammatory reactions during immune response, as well as in the formation of acute and chronic allergic diseases, including anaphylaxis , asthma , atopic ...
More specifically, they form the most abundant type of granulocytes and make up 40% to 70% of all white blood cells in humans. [1] Their functions vary in different animals. [2] They are also known as neutrocytes, heterophils or polymorphonuclear leukocytes.
An excess of white blood cells is usually due to infection or inflammation. Less commonly, a high white blood cell count could indicate certain blood cancers or bone marrow disorders. The number of leukocytes in the blood is often an indicator of disease, and thus the white blood cell count is an important subset of the complete blood count.
A band cell (also called band neutrophil, band form or stab cell) is a cell undergoing granulopoiesis, derived from a metamyelocyte, and leading to a mature granulocyte. It is characterized by having a curved but not lobular nucleus. [1] The term "band cell" implies a granulocytic lineage (e.g., neutrophils). [2]
