| globular leukocyte | A type of wandering cell with a small, round nucleus found in the epithelium and lamina propria of the intestinal mucosa of many animals; its cytoplasm contains large eosinophilic globules or droplets. (05 Mar 2000) |
|---|---|
| granular leukocyte | Any one of the polymorphonuclear leukocyte's, especially a neutrophilic leukocyte. See: granulocyte, basophilic leukocyte, eosinophilic leukocyte. (05 Mar 2000) |
| chemotaxis, leukocyte | The movement of leukocytes in response to a chemical concentration gradient or to products formed in an immunologic reaction. (12 Dec 1998) |
| motile leukocyte | Any leukocyte that manifests active ameboid movement, especially a mature granulocytic leukocyte (eosinophils are less motile than neutrophils or basophils); monocytes manifest a slow, but persistent, wavelike movement. (05 Mar 2000) |
| multinuclear leukocyte | Small, actively motile white blood cells containing many lysosomes and specialising in phagocytosis. (09 Oct 1997) |
| polymorphonuclear leukocyte | Small, actively motile white blood cells containing many lysosomes and specialising in phagocytosis. (09 Oct 1997) |
| cystinotic leukocyte | A leukocyte having an enhanced content of cystine, found in patients with disorders characterised by the storage of cystine; within the leukocyte, the cystine, largely in noncrystalline form, is associated with dense lysosomal particles. (05 Mar 2000) |
| human leukocyte antigen | <immunology> A genetic fingerprint on white blood cells and platelets, composed of proteins that play a critical role in activating the bodys immune system to respond to foreign organisms. Acronym: HLA (16 Dec 1997) |
| human leukocyte-associated antigens | Proteins on the outer part of body cells that help fight illness. These proteins vary from person to person. Scientists think that people with certain types of HLA antigens are more likely to develop insulin-dependent diabetes.The HLA antigens are also responsible for histocompatibility reactions. (09 Oct 1997) |
| hyaline leukocyte | Old term for a monocyte, and for a mononuclear macrophage in various lesions. (05 Mar 2000) |
| nonfilament polymorphonuclear leukocyte | <haematology> A neutrophil, basophil, or eosinophil that is not completely matured, i.e., the lobes of the nuclei remain connected with bands of chromatin, in contrast to the thin strands observed in mature cells. (05 Mar 2000) |
| nongranular leukocyte | <haematology> A general, non-specific term frequently used with reference to lymphocytes, monocytes, and plasma cells; although the cytoplasm of a lymphocyte or monocyte contains tiny granules, it is nongranular in comparison with that of a neutrophil, basophil, or eosinophil. See: leukocyte. Synonym: agranular leukocyte. (05 Mar 2000) |
| nonmotile leukocyte | <haematology> A term sometimes used with reference to lymphocytes, monocytes, and plasma cells; although such forms actually have some degree of motility, they are nonmotile in comparison with the actively ameboid, neutrophilic, basophilic, and eosinophilic leukocyte's. (05 Mar 2000) |
| oxyphilic leukocyte | A polymorphonuclear leukocyte characterised by many large or prominent, refractile, cytoplasmic granules that are fairly uniform in size and bright yellow-red or orange when treated with Wright's or similar stains; the nuclei are usually larger than those of neutrophils, do not stain as deeply, and characteristically have two lobes (a third lobe is sometimes interposed on the connecting strand of chromatin); these leukocyte's are motile phagocytes with distinctive antiparasitic functions. Synonym: acidophilic leukocyte, eosinocyte, eosinophil, eosinophile, oxyphil, oxyphile, oxyphilic leukocyte. (05 Mar 2000) |
| transitional leukocyte | Old term for a monocyte. (05 Mar 2000) |
