| focal adhesion | <cell biology> Areas of close apposition and thus presumably anchorage points, of the plasma membrane of a fibroblast (for example) to the substratum over which it is moving. Usually 1m x 0.2 m with the long axis parallel to the direction of movement, always associated with a cytoplasmic microfilament bundle that is attached via several proteins to the plasma membrane at an area of high protein concentration (this is noticeably electron dense in electron micrographs). Focal adhesions tend to be characteristic of slow moving cells. (18 Nov 1997) |

| acidophilic 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) |
| agranular 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) |
| automated differential leukocyte counter | An instrument using digital imaging or cytochemical techniques to differentiate leukocytes. (05 Mar 2000) |
| basophilic leukocyte | A polymorphonuclear leukocyte characterised by many large, coarse, metachromatic granules (dark purple or blue-black when treated with Wright's or similar stains) that usually fill the cytoplasm and may almost mask the nucleus; these leukocyte's are unique in that they usually do not occur in increased numbers as the result of acute infectious disease, and their phagocytic qualities are probably not significant; the granules, which contain heparin and histamine, may degranulate in response to hypersensitivity reactions and can be of significance in general inflammation. Synonym: basocyte, basophilocyte, mast leukocyte. (05 Mar 2000) |
| mast leukocyte | A polymorphonuclear leukocyte characterised by many large, coarse, metachromatic granules (dark purple or blue-black when treated with Wright's or similar stains) that usually fill the cytoplasm and may almost mask the nucleus; these leukocyte's are unique in that they usually do not occur in increased numbers as the result of acute infectious disease, and their phagocytic qualities are probably not significant; the granules, which contain heparin and histamine, may degranulate in response to hypersensitivity reactions and can be of significance in general inflammation. Synonym: basocyte, basophilocyte, mast leukocyte. (05 Mar 2000) |
| 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) |
| segmented leukocyte | Any mature polymorphonuclear leukocyte, especially a neutrophilic leukocyte. (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) |
