Agranulocyte
Agranulocytes are leukocytes without the presence of visible granules in the cytoplasm, but may have nonspecific granules called azurophiles, which may also be present in granulocytes, these granules are very small, looking like small points in the cytoplasm and are blue in color. The agranulóticos have a nucleus rounded or indented. They have only primary granules, which are lysosomes. Agranulocytes include monocytes and lymphocytes: ▪ Monocytes when stimulated by foreign substances are transformed into macrophages that remove protein debris and phagocyte bacteria. Monocytes are found in circulating blood and macrophages are found in tissues. ▪ Lymphocytes are produced in bone marrow and generate T cells and B cells, mediators of the immune system, represent 20% to 25% of leukocytes in the blood. Agranulocytosis is unrelated to agranulocytes, agranulocytosis is a condition in which granulocytes, especially neutrophils, are absent. References ^ Gerard J. Tortora. Microbiology.
