1. Developmental and stress induced changes in peptide and catecholamine content of the paraaortic paraganglia
Sammanfattning : The paraaortic body (PAB) is the largest extra-adrenal paraganglion and during the perinatal period it contains a substantial amount of catecholamines (CAs). The PAB also contain peptides, whose function in the PAB is not clear. LÄS MER
2. Secretory activity in isolated rat stomach ECL cells
Sammanfattning : ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They are important regulators of gastric acid secretion in the stomach by virtue of their histamine synthesizing and secreting capacity. Histamine in turn stimulates parietal cells to secrete acid.

3. Neuropeptide Y Y1 receptor mechanisms in sympathetic vascular control
Sammanfattning : It was demonstrated that the Y1 receptor was the predominant vascular neuropeptide Y (NPY) receptor in pig kidney and hind limb as exogenous and endogenous NPY evoked vasoconstrictor responses that were almost or totally abolished by the selective non-peptide Y1 receptor antagonist, BIBP 3226. Furthermore, renal vasoconstriction was evoked by NPY and a peptide Y1 agonist, but not by a Y 2 agonist, and these responses were strongly reduced by another non-peptide Y, receptor antagonist, SR 120107A.

4. Vesicle proteins as markers for neuroendocrine tumors
Sammanfattning : The neuroendocrine (NE) tumours comprise a diversity of tumours which share commonproperties, e.g. the capacity to produce, store and release hormones. A prominent feature ofthe NE phenotype is the production of secretory granules with associated vescicle proteins,e. LÄS MER
5. Midgut carcinoid tumours - biochemical and therapeutic aspects
Sammanfattning : The biology of human midgut carcinoid tumour was studied experimentally in primary cell culture and clinically in patients with the midgut carcinoid syndrome. In cell cultures, tumour cells had a secretory pattern of 5-HTP, 5-HT and 5-HIAA specific for each tumour indicating individual regulation of synthesis/degradation. LÄS MER
