OBJECTIVE Subjects with type 2 diabetes are at risk for vascular injury. Several vasoactive factors (e.g., angiotensin) have been implicated. We hypothesize that adrenomedullin, a novel vascoactive factor, is deranged in subjects with type 2 diabetes. RESEARCH DESIGN AND METHODS Using a new immunoluminometric method, plasma midregional proadrenomedullin (MR-proADM) was measured in four groups...

We examined the roles of central adrenomedullin, proadrenomedullin N-terminal 20 peptide (PAMP), and calcitonin gene-related peptide (CGRP) on the baroreceptor reflex in conscious rabbits. Intracerebroventricular injection of adrenomedullin (0.2 and 1 nmol/80 microL) elicited dose-related increases in arterial pressure and renal sympathetic nerve activity. On the other hand, a subpressor dose o...

Fungi are of increasing importance in sepsis. However, culture-based diagnostic procedures are associated with relevant weaknesses. Therefore, culture- and next-generation sequencing (NGS)-based fungal findings as well as corresponding plasma levels of β-d-glucan, interferon gamma (INF-γ), tumor necrosis factor alpha (TNF-α), interleukin (IL)-2, -4, -6, -10, -17A, and mid-regional proadrenomedu...

Proadrenomedullin N-terminal 20 peptide (PAMP-[1-20]; ARLDVASEFRKKWNKWALSR-amide) is a potent hypotensive and catecholamine release–inhibitory peptide released from chromaffin cells. We studied the mechanism of PAMP action and how its function is linked to structure. We tested human PAMP-[1-20] on catecholamine secretion in PC12 pheochromocytoma cells and found it to be a potent, dose-dependent...

Adrenomedullin is a vasodilatory polypeptide with pleiotropic effects secreted by various organs. Adrenomedullin is produced first as a prepropeptide, and then cleaved into mature adrenomedullin and mid-regional proadrenomedullin. Whereas levels of the latter have been shown to correlate with severity of sepsis and carry prognostic value, adrenomedullin plays a role in vascular tone homeostasis...
