Agranulocyte

A nonspecific term for any white cells lacking granules—e.g., monocytes and lymphocytes. The term provides little value when compared to other, more widely-used and specific alternatives, especially the widely-used and understood “round cell.”

White blood cell without granules (e.g., monocytes and lymphocytes).

agranulocyte

a type of LEUCOCYTE (white blood cell) with nongranular cytoplasm and a large spherical nucleus. They are produced either in the LYMPHATIC SYSTEM or the bone marrow. Agranulocytes form about 30% of all leucocytes and are of two types, LYMPHOCYTES and MONOCYTES.

The Granulocyte consist of Neutrophils, basophils, eosinophils and agranulocytes i.e.
When analyzing the DEGs at different time points, we found 46, 46, 26, and 24 genes commonly upregulated or downregulated in the pathways of agranulocyte adhesion and diapedesis, granulocyte adhesion and diapedesis, IL-10 signaling, and IL-6 signaling, respectively (see the intersect in red, Figures 2(a), 2(b), 2(c), and 2(d)).
Signaling pathway analysis suggested that agranulocyte adhesion and diapedesis, granulocyte adhesion and diapedesis pathway, IL-6 signaling, and IL-10 signaling are the major immune/inflammation pathways upregulated during nerve degeneration and regeneration.

On Hemacolor smears, 2 hemocyte types were distinguished by light microscopy: granulocytes and hyalinocytes (or agranulocytes) according to the presence or the absence of cytoplasmic granules.
Cheng (1981) presented a morphological scheme based on numbers of cytoplasmic granules, dividing cells into 2 types: granulocytes, cells containing granules that ranged from very few to numerous; and agranulocytes, cells containing few or no granules.
After the separation in this type of density gradient, the granulocytes were separated from agranulocytes and pure granulocytes were obtained.
