| Borst-Jadassohn type intraepidermal epithelioma | <tumour> Precancerous lesions clinically suggestive of actinic or seborrheic keratosis, with nests of immature or abnormal keratinocytes within the epidermis. (05 Mar 2000) |
|---|---|
| intraepidermal | Within the epidermis. (05 Mar 2000) |
| intraepidermal carcinoma | <tumour> Carcinoma in situ of the skin; e.g., Bowen's disease. (05 Mar 2000) |
| activated macrophage | A mature macrophage, in an active metabolic state, that is cytotoxic to tumour/target cells, usually following exposure to certain cytokines. Synonym: armed macrophage. (05 Mar 2000) |
| alveolar macrophage | Macrophage found in lung and that can be obtained by lung lavage, responsible for clearance of inhaled particles and lung surfactant. Metabolism slightly different from peritoneal macrophages (more oxidative metabolism), often have multivesicular bodies that may represent residual undigested lung surfactant. (18 Nov 1997) |
| alveolar macrophage elastase | <enzyme> Metalloproteinase found in human alveolar macrophages Registry number: EC 3.4.24.- Synonym: elastase, alveolar macrophage, metalloproteinase elastase, human macrophage metalloelastase, mmp12 gene product, mmp-12 gene product, mme gene product, macrophage metalloelastase (26 Jun 1999) |
| armed macrophage | A mature macrophage, in an active metabolic state, that is cytotoxic to tumour/target cells, usually following exposure to certain cytokines. Synonym: armed macrophage. (05 Mar 2000) |
| associated macrophage | A mature macrophage in an active metabolic state that is cytotoxic to tumour/target cells, usually following exposure to certain cytokines. (05 Mar 2000) |
| macrophage | Relatively long lived phagocytic cell of mammalian tissues, derived from blood monocyte. Macrophages from different sites have distinctly different properties. Main types are peritoneal and alveolar macrophages, tissue macrophages (histiocytes), Kupffer cells of the liver and osteoclasts. In response to foreign materials may become stimulated or activated. Macrophages play an important role in killing of some bacteria, protozoa and tumour cells, release substances that stimulate other cells of the immune system and are involved in antigen presentation. May further differentiate within chronic inflammatory lesions to epithelioid cells or may fuse to form foreign body giant cells or Langhans giant cells. (18 Nov 1997) |
| macrophage-1 antigen | An adhesion-promoting leukocyte surface membrane heterodimer. The alpha subunit consists of the CD11b antigen and the beta subunit of the CD18 antigen (antigens, CD18). The antigen, which is an integrin, functions both as a receptor for complement 3 and in cell-cell and cell-substrate adhesive interactions. (12 Dec 1998) |
| macrophage-activating factor | An agent that stimulates macrophages to attack and ingest cancer cells. They are secreted by stimulated lymphocytes that prime macrophages to become non-specifically cytotoxic to tumours. They also modulate the expression of macrophage cell surface ia antigens. One maf is interferon-gamma (interferon type II). Other factors antigenically distinct from ifn-gamma have also been identified. (12 Dec 1998) |
| macrophage activation | The process of altering the morphology and functional activity of macrophages so that they become avidly phagocytic. It is initiated by lymphokines, such as the macrophage activation factor (maf) and the macrophage migration-inhibitory factor (mmif), immune complexes, c3b, and various peptides, polysaccharides, and immunologic adjuvants. (12 Dec 1998) |
| macrophage colony-stimulating factor | <growth factor> A glycoprotein growth factor that causes the committed cell line to proliferate and mature into macrophages. A cytokine synthesised by mesenchymal cells that stimulates pluripotent stem cells of bone marrow into differentiating towards the production of monocytes (mononuclear phagocytes). The compound stimulates the survival, proliferation, and differentiation of haematopoietic cells of the monocyte-macrophage series. It is a disulfide-bonded glycoprotein dimer with a mw of 70 kD and binds to a single class of high affinity receptor which is identical to the product of the c-fms proto-oncogene. See: colony-stimulating factors. Chemical name: Colony-stimulating factor 1 Acronym: M-CSF (12 Dec 1998) |
| macrophage inflammatory protein | <cytokine> A chemokine that is chemotactic for neutrophils and monocytes, stimulates macrophages, and may play a role in regulating haematopoiesis. Its two variants, mip-1alpha and mip-1beta, are 60% homologous to each other. They are heparin-binding proteins that exhibit a number of inflammatory and immunoregulatory activities. Originally identified as secretory products of macrophages, these chemokines are produced by a variety of cell types including neutrophils, fibroblasts, and epithelial cells. They most likely also play a significant role in respiratory tract defenses. (20 Sep 2002) |
| macrophage inhibition factor | <cytokine> A group of lymphokines (including a 14 kD glycoprotein) produced by activated T lymphocytes that reduces macrophage mobility and probably increases macrophage macrophage adhesion. (18 Nov 1997) |
