Agranulocyte

Agranulocyte (agranulocytus; a- + granulocyte; synonym non-granular leukocyte) is a type of leukocyte (white blood cell) that does not contain grains (granules) in the cytoplasm.

Agranulocytes include:

1. Lymphocytes are the main cells of the immune system, responsible for specific immunity.

2. Monocytes are large phagocytic cells that carry out nonspecific defense of the body.

3. Neutrophils are the most numerous leukocytes in the blood of a healthy person. They play an important role in nonspecific immunity.

4. Eosinophils - participate in protection against parasites and allergic reactions.

5. Basophils - play a role in allergic and inflammatory reactions.

Thus, agranulocytes are a type of leukocytes that do not contain grains in the cytoplasm and perform immune and protective functions in the body.

Agranulocytes in medicine are called non-granular leukocytes (account for 45%) or agranulocyte leukocytes. In other words, these are white blood cells, but without granularity, since there is no granularity. Mostly such cells are found in the hematopoietic organs of vertebrates and are exogenously present in the blood serum at a concentration of 0.04% - 0.
