Definition of granulocyte in English:



  • A white blood cell with secretory granules in its cytoplasm, i.e. a neutrophil, basophil, or eosinophil.

    • ‘White blood cells called granulocytes and lymphocytes travel along the walls of blood vessels.’
    • ‘The inflammatory response to viral-induced bronchiolitis includes bronchial obstruction, increased airway secretion, mucosal edema, and infiltration of inflammatory cells including eosinophil granulocytes.’
    • ‘It has to be taken into consideration that many cells of the lung, such as macrophages, eosinophils, dendritic cells, mast cells and granulocytes, interact with lymphocytes and vice versa via a number of cytokines and chemokines.’
    • ‘These stem cells proliferate and differentiate into granulocytes (neutrophils, eosinophils and basophils), monocytes and lymphocytes, which together comprise the absolute white blood cell count.’
    • ‘These are the eosinophils, neutrophils, and basophils (collectively known as granulocytes or polymorphonuclear leukocytes), mast cells, and monocytes.’


Early 20th century: from late Latin granulum ‘granule’ + -cyte.
