| receptors, pituitary hormone-regulating hormone | Cell surface receptors that bind the hypothalamic hormones regulating pituitary cell differentiation, proliferation, and hormone synthesis and release, including the pituitary-releasing and release-inhibiting hormones. The pituitary hormone-regulating hormones are also released by cells other than hypothalamic neurons, and their receptors also occur on non-pituitary cells, especially brain neurons, where their role is less well understood. Receptors for dopamine, which is a prolactin release-inhibiting hormone as well as a common neurotransmitter, are not included here. (12 Dec 1998) |
|---|---|
| growth hormone inhibiting hormone | <protein> Gastrointestinal and hypothalmic peptide hormone (two forms: 14 and 28 residues), found in gastric mucosa, pancreatic islets, nerves of the gastrointestinal tract, in posterior pituitary and in the central nervous system. Inhibits gastric secretion and motility: in hypothalamus/pituitary inhibits somatotropin release. (18 Nov 1997) |
| growth hormone-regulating hormone | <endocrinology> Hypothalamic hormones that induce (somatoliberin) or inhibit (somatostatin) the release of growth hormone (somatotropin). (18 Nov 1997) |
| growth hormone-releasing hormone | <endocrinology> Peptide hormone related to the glucagon family, released from the pituitary, acts on the adenohypophysis to release growth hormone. Synonym: somatoliberin, growth hormone-releasing factor. (20 Sep 2002) |
| hormones, hormone substitutes, and hormone antagonists | A collective grouping for both naturally occurring and synthetic hormones, substitutes, and antagonists. (12 Dec 1998) |
| follicle-stimulating hormone-releasing hormone | A decapeptide of hypothalamic origin capable of accelerating pituitary secretion of follitropin. Synonym: follicle-stimulating hormone-releasing factor, follicle-stimulating hormone-releasing hormone. Origin: follicle-stimulating hormone + L. Libero, to free, + -in (05 Mar 2000) |
| luteinizing hormone/follicle-stimulating hormone-releasing factor | gonadotrophin-releasing hormone |
| luteinizing hormone-releasing hormone | A hormone that controls sex hormones in men and women. Also called lhrh. (12 Dec 1998) |
| chemotactic | A response of motile cells or organisms in which the direction of movement is affected by the gradient of a diffusible substance. Differs from chemokinesis in that the gradient alters probability of motion in one direction only, rather than rate or frequency of random motion. (18 Nov 1997) |
| chemotactic factors | Chemical substances that attract or repel cells or organisms. The concept denotes especially those factors released as a result of tissue injury, invasion, or immunologic activity, that attract leukocytes, macrophages, or other cells to the site of infection or insult. (12 Dec 1998) |
| chemotactic factors, eosinophil | Cytotaxins liberated from normal or invading cells that specifically attract eosinophils; they may be complement fragments, lymphokines, neutrophil products, histamine or other; the best known is the tetrapeptide ecf-a, released mainly by mast cells. (12 Dec 1998) |
| chemotactic factors, macrophage | Cytotaxins liberated from normal or invading cells that specifically attract macrophages. They may be lymphokines, products of antigen, antibody and complement interactions or other. (12 Dec 1998) |
| chemotactic protein methylesterase | <enzyme> Demethylates methyl-accepting chemotaxis proteins Registry number: EC 3.1.1.- Synonym: chemotactic methylesterase, carboxymethylesterase of chemotaxis, cheb methylesterase (26 Jun 1999) |
| monocyte chemotactic and activating factor | Cytokine of the C C subfamily, co induced with IL-8 on stimulation of endothelial cells, fibroblasts or monocytes that activates and is chemotactic for, monocytes. A chemokine. (18 Nov 1997) |
| monocyte derived neutrophil chemotactic factor | <cytokine> A cytokine that activates neutrophils and attracts neutrophils and T-lymphocytes. It is released by several cell types including monocytes, macrophages, T-lymphocytes, fibroblasts, endothelial cells, and keratinocytes by an inflammatory stimulus. Il-8 is a member of the beta-thromboglobulin superfamily and structurally related to platelet factor 4. Acronym: IL-8 (12 Dec 1998) |
