brain natriuretic peptide(redirected from Brain natriuretic factor)
brain natriuretic peptide (BNP)
a hormone, originally isolated from porcine brain tissue, having biological effects similar to those of atrial natriuretic peptide and stored mainly in the myocardium of the cardiac ventricles. Blood levels of BNP are elevated in hypervolemic states, such as congestive heart failure and hypertension.
brain natriuretic peptideAn atrial natriuretic peptide-like brain peptide produced predominantly in the cerebral ventricles, which induces diuresis and is secreted in response to fluid overload, as occurs in congestive heart failure.
peptide(pep'tid?) [ pept(ic) + -ide]
A compound containing two or more linked amino acids.
atrial natriuretic peptideAbbreviation: ANP
Atrial natriuretic factor.
brain natriuretic peptideB-type natriuretic peptide.
B-type natriuretic peptideAbbreviation: BNP
A hormone secreted by the left or right ventricle of the heart Concentration of this peptide in the bloodstream rises during episodes of decompensated heart failure.See: brain natriuretic peptide
A peptide that readily crosses cell membranes and therefore can influence cellular functions or carry other molecules that can directly or indirectly perform the same tasks.
endogenous opioid peptide
Any of a group of more than 15 substances present in the brain, certain endocrine glands, and the gastrointestinal tract. They have morphine-like analgesic properties, behavioral effects, and neurotransmitter and neuromodulator functions. Included in this group of chemicals are endorphins, enkephalins, and dynorphin.
glucose-dependent insulinotropic peptide
A hormone released by cells in the upper gastrointestinal tract in response to sugary or fatty meals. It stimulates beta cells in the pancreas to secrete insulin.
Any of the peptides having a strong affinity for binding with class I or II histocompatibility antigens and for stimulating a response by T lymphocytes. Immunodominant peptides are produced by antigen processing, are expressed on the surface of macrophages and other antigen-presenting cells, and may be useful both in desensitizing people to allergens and in vaccine production.Synonym: immunodominant epitope
Any peptide that stimulates the kidneys to excrete salt and water.
An appetite-regulating protein released by L cells of the mucosa of the gastrointestinal tract in response to a meal. It binds to cells in the arcuate nucleus of the brain, decreases the desire to eat, and creates a feeling of fullness.
