  2. 1. Developmental and stress induced changes in peptide and catecholamine content of the paraaortic paraganglia

    Author : Lars-Magnus Wikström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : paraganglia; adrenal gland; enkephalin; galanin; NPY; catecholamines; development; asphyxia; hypoglycemia; reserpine;

    Abstract : 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. READ MORE

  4. 2. Secretory activity in isolated rat stomach ECL cells

    Author : Erik Lindström; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocrinology; Calcium channels; Adrenaline; Pancreastatin; Prostaglandin E2; Galanin; Somatostatin; Histamine; Gastrin; VIP; PACAP; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Abstract : 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.

  5. 3. Neuropeptide Y Y1 receptor mechanisms in sympathetic vascular control

    Author : Rickard E Malmström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Sympathetic vasoconstriction; neuropeptide Y1 Y; receptor antagonists; BIBP 3226; SR 120107A; ischaemia; pig.;

    Abstract : 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.

  6. 4. Vesicle proteins as markers for neuroendocrine tumors

    Author : Anne-Marie Levin Jakobsen; Göteborgs universitet; []
    Keywords : Neuroendocrine tumours; gastrointestinal tract; pancreas; adrenal; vesicle proteins; ; SV2; NESP55; VMAT1; VMAT2; MIBG;

    Abstract : 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. READ MORE

  7. 5. Methological advances in the examination of the dopamine system in brain

    Author : Judit Sóvágó; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Dopamine-D2 D3 receptors; brain; [35S]GTPgS binding autoradiography; positron emission tomography; partial volume effect;

    Abstract : The dopamine (DA) system in brain has attracted considerable attention in neuroscience due to its involvement in fundamental brain functions and its postulated role in the pathophysiology of several neuropsychiatric disorders. Radioligand binding techniques in vitro and in vivo, such as receptor binding autoradiography and positron emission tomography (PET) have substantially contributed to our understanding of the DA system.
