  Brain Natriuretic Peptide   (Site not responding. Last check: 2007-09-12)
Brain natriuretic peptide (BNP) belongs to a family of at least 3 members (atrial natriuretic peptide, ANP, BNP, C-type natriuretic peptide, CNP) that exert local and humoral effects on blood pressure and extracellular body-fluid volume.
BNP is a key cardiovascular peptide hormone that is derived mainly from the left ventricle upon increased wall stress (21).
BNP may be viewed as a counter measure to neurohumoral activation in heart failure or acute coronary syndromes.

 B-Type Natriuretic Peptide   (Site not responding. Last check: 2007-09-12)
BNP is predominantly secreted by the ventricles of the heart in response to increased pressure.
BNP levels correlate with end-diastolic pressure and tend to be increased in patients with diminished left ventricular ejection fraction.
BNP levels have been shown to be useful in the diagnosis of patients with symptoms that are consistent with CHF.

 Brain natriuretic peptide in the management of heart failure : the versatile neurohormone CHEST - Find Articles   (Site not responding. Last check: 2007-09-12)
Brain natriuretic peptide (BNP), also called B-type natriuretic peptide, is a member of a family of structurally related hormones, the natriuretic peptides.
Current data suggest that measurement of BNP plasma concentrations is a useful tool in the diagnosis of acute heart failure in patients presenting to an emergency department with acute dyspnea.
In humans, BNP is mainly secreted from the heart, and mostly from the ventricles in both healthy individuals and patients with congestive heart failure.

 Brain natriuretic peptide - Wikipedia, the free encyclopedia
Brain natriuretic peptide (also known as B-type natriuretic peptide or "GC-B") is a 32-amino-acid polypeptide secreted by the ventricles of the heart in response to excessive stretching of myocytes (heart muscles cells) in the ventricles.
Tests showing elevated levels of BNP or NT-proBNP in the blood are used as a diagnosis of heart failure and may be useful to establish prognosis in heart failure, as both markers are typically higher in patients with worse outcome.
Brain natriuretic peptide was originally identified in extracts of porcine brain, but in humans it is produced mainly in the cardiac ventricles.

 Hormone brain natriuretic peptide can predict pulmonary hypertension
Measuring levels of a hormone called brain natriuretic peptide in individuals with serious lung disease can predict the presence of pulmonary hypertension and a patient's potential death or survival, regardless of clinical severity or the cause of illness.
BNP, a hormone produced by the heart, is activated by different cardiovascular diseases.
The investigators concluded that BNP is a prognostic marker and a screening parameter for significant pulmonary hypertension in chronic lung disease.

 Monoclonal antibodies against N-Terminus proBNP - Patent 6960472
The production of antibodies by means of peptide immunization is possible in principle but the affinity regarding the whole molecule generally is too low to reach the necessary sensitivity in a test procedure.
In addition, there is a danger that when using peptides the antibodies obtained can for example identify the C-terminus of the peptide and can therefore only bind to this fragment of the whole molecule, thus resulting in antibodies which generally cannot bind to the whole molecule, or can do so to only a limited extent.
A single peptide chain is usually not very immunogenic in experimental animals, and it is generally necessary to couple the peptide to a carrier protein such as KLH or bovine serum albumin.
