| leukocyte interferon | <cytokine> One of the type I interferons produced by peripheral blood leukocytes or lymphoblastoid cells when exposed to live or inactivated virus, double-stranded RNA, or bacterial products. It is the major interferon produced by virus-induced leukocyte cultures and, in addition to its pronounced antiviral activity, causes activation of NK cells. It is used experimentally in the treatment of hairy-cell leukaemia. A number of different subtypes exist that are elaborated by leukocytes in response to viral infection or stimulation with double-stranded RNA; IFN-alpha-2A and -2B are protein products made by recombinant DNA techniques and are used as antineoplastic agents. See: interferon-alpha 2a, interferon-alpha 2b Synonym: leukocyte interferon. Pharmacological action: antineoplastic agent, antiviral agent. (20 Sep 2002) |

| leukocyte migration-inhibitory factors | Protein factor(s) released by sensitised lymphocytes (and possibly other cells) that inhibit the movement of leukocytes, especially polymorphonuclear cells, away from their site of release. Assays for these factors are used as tests for cellular immunity. Two of the common assays are the leukocyte migration capillary tube technique (lmct) and the leukocyte migration agarose technique (lmat). (12 Dec 1998) |
| leukocyte transfusion | The transfer of leukocytes from a donor to a recipient or reinfusion to the donor. (12 Dec 1998) |
| leukocyte tyrosine kinase receptor tyrosine kinase | <enzyme> May be receptor for pre-b lymphocyte growth or differentiation factor; aa sequence given in first source Registry number: EC 2.7.1.- Synonym: ltk receptor tyrosine kinase, ltk receptor tk, ltk protein, leukocyte tyrosine kinase (ltk) (26 Jun 1999) |
| leukocyte-adhesion deficiency syndrome | <syndrome> Rare, autosomal recessive disorder caused by deficiency of the beta 2 integrin receptors (receptors, leukocyte-adhesion) comprising the CD11/CD18 family of glycoproteins. The syndrome is characterised by abnormal adhesion-dependent functions, especially defective tissue emigration of neutrophils, leading to recurrent infection. (12 Dec 1998) |
| leukocytes | Cells that help the body fight infections and other diseases. Also called white blood cells (wbcs). (12 Dec 1998) |
| leukocytes, mononuclear | Mature lymphocytes and monocytes transported by the blood to the body's extravascular space. They are morphologically distinguishable from mature granulocytic leukocytes by their large, non-lobed nuclei and lack of coarse, heavily stained cytoplasmic granules. (12 Dec 1998) |
| leukocythemia | A seldom used term for leukaemia. Origin: Leukocyte + G. Haima, blood (05 Mar 2000) |
| leukocytic | Pertaining to or characterised by leukocytes. Synonym: leukocytal. (05 Mar 2000) |
| leukocytic pyrogens | Fever producing substance released by leucocytes (and Kuppfer cells in particular) that acts on the hypothalamic thermoregulatory centre. Now known to be interleukin-1. (18 Nov 1997) |
| leukocytic sarcoma | <haematology> An acute or chronic disease of unknown cause in man and other warm blooded animals that involves the blood forming organs, is characterised by an abnormal increase in the number of leucocytes in the tissues of the body with or without a corresponding increase of those in the circulating blood and is classified according of the type leucocyte most prominently involved. (18 Nov 1997) |
| leukocytoblast | A non-specific term for any immature cell from which a leukocyte develops, including lymphoblast, myeloblast, and the like. Origin: Leukocyte + G. Blastos, germ (05 Mar 2000) |
| leukocytoclasis | Karyorrhexis of leukocytes. Origin: Leuko-+ G. Kytos, cell, + klasia, a breaking (05 Mar 2000) |
| leukocytoclastic vasculitis | Cutaneous acute vasculitis characterised clinically by palpable purpura, especially of the legs, and histologically by exudation of the neutrophils and sometimes fibrin around dermal venules, with nuclear dust and extravasation of red cells; may be limited to the skin or involve other tissues as in Henoch-Schonlein purpura. See: cutaneous vasculitis. Origin: G. Leukos, white, + kytos, cell, + klastos, broken, fr. Klao, to break (05 Mar 2000) |
| leukocytogenesis | The formation and development of leukocytes. Origin: Leukocyte + G. Genesis, production (05 Mar 2000) |
