neutrophil (redirected from hyposegmented neutrophil)

neutrophil /neu·tro·phil/ (noo´tro-fil)

1. a granular leukocyte having a nucleus with three to five lobes connected by threads of chromatin, and cytoplasm containing very fine granules; cf. heterophil.

2. any cell, structure, or histologic element readily stainable with neutral dyes.

rod neutrophil , stab neutrophil one whose nucleus is not divided into segments.

neu·tro·phil (ntr-fl) or neu·tro·phile (-fl)

n.

1. A neutrophil cell, especially an abundant type of granular white blood cell that is highly destructive of microorganisms.

2. A cell or tissue that manifests no special affinity for acid or basic dyes.

adj.

Not stained strongly or definitely by either acid or basic dyes but stained readily by neutral dyes. Used especially of white blood cells.

Neutrophil

The primary type of white blood cell involved in inflammation. Neutrophils are a type of granulocyte, also known as a polymorphonuclear leukocyte.

neutrophil

[no̅o̅′trəfil]

Etymology: L, neuter + Gk, philein, to love

a polymorphonuclear, granular leukocyte that stains easily with neutral dyes. The nucleus stains dark blue and contains three to five lobes connected by slender threads of chromatin. The cytoplasm contains fine, inconspicuous granules. Neutrophils are the circulating white blood cells essential for phagocytosis and proteolysis by which bacteria, cellular debris, and solid particles are removed and destroyed. A neutrophil count less than or equal to 500 may be life-threatening. See also basophil, eosinophil, granulocyte, polymorphonuclear leukocyte.

neutrophil

1. one of the three granular leukocytes having a nucleus with three to five lobes connected by threads of chromatin, and cytoplasm containing lysosomes that stain characteristically and enable neutrophils to be distinguished from basophils and eosinophils; called also a granulocyte or polymorphonuclear leukocyte. See also heterophil (1).

2. any cell, structure or histological element readily stainable with neutral dyes.

band neutrophil

see stab neutrophil (below).

neutrophil chemotactic factor

see chemotactic factor.

hypersegmented neutrophil

increased number of nuclear lobes; seen in hyperadrenocorticism or during treatment with corticosteroids, and in blood that has been in transit for long periods.

hyposegmented neutrophil

a lack of nuclear lobes; may occur in chronic infections and is a feature of pelger-huet anomaly.

neutrophil:lymphocyte ratio

correlates directly with the magnitude of the total leukocyte count in response to disease in domestic animals; it varies from 0.5 in cattle to 3.5 in dogs.

stab neutrophil

a neutrophilic leukocyte whose nucleus is not divided into segments.

toxic neutrophil

one with blue-black or large reddish cytoplasmic granules and diffuse cytoplasmic basophilia and vacuolation; caused by disruption of maturation.

neutrophil

 A phagocytic WBC, normally constituting 60-70% of circulating WBCs. See Band, Dysplastic neutrophil, Hypersegmented neutrophil, Polymorphonuclear neutrophil.
