  2. 1. Expression and Regulation of Neuropeptide Y (NPY) in the Islets of Langerhans

    Author : Ulrika Myrsén Axcrona; Neuroendokrin cellbiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocrinology; regulatory peptides; diabetes; glucocorticoids; beta cell; islet hormones; neuropeptide Y; insulin; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Abstract : This thesis deals with the expression, localization and regulation of neuropeptide Y (NPY) in the pancreatic islets of Langerhans under normal and experimental conditions. NPY is widely distributed in the mammalian nervous system and belongs to a family of closely related petides also comprising peptide YY (PYY) and pancreatic polypeptide (PP). READ MORE

  4. 2. On the role of nitric oxide in uterine secretion

    Author : Birgitta Mörlin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Autonomic nerves; endometrial and cervical secretion; nitric oxide; guineapig.;

    Abstract : Background: Uterine secretion is important in many different aspects of reproduction e.g. sperm transport and survival, fertilization, nourishment of the ovum and implantation. A cholinergic autonomic nervous secretory innervation has been established and modulation of the secretion by prostaglandins and NSAID drugs has been postulated. READ MORE

    Abstract : Asthma is one of the commonest diseases in industrialized countries. The cause and mechanisms of !he disorder are still not fully unden;tood, al!hough it is known that inflammation in !he airways plays an important role. Inflammatory mediators, e.g. READ MORE

  6. 4. 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.
