  1. 1. Neuropeptide Y Receptors in Human, Guinea pig and Chicken : Cloning, in vitro Pharmacology and in situ Hybridization

    Författare :Sara Holmberg; Helen Cox; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; G-protein coupled receptor; neuropeptide Y; neuropeptide Y receptor; ortholog; chicken; guinea pig; mutagenesis; receptor computer modeling; mRNA in situ hybridization; Neurovetenskap; Neurology; Neurologi; medicinsk farmakologi; Medical Pharmacology;

    Sammanfattning : Neuropeptide Y (NPY) is known to influence a vast number of physiological and behavioral processes such as vasoconstriction, circadian rhythms, feeding, anxiety and memory. Peptides of the NPY family bind to five different cloned G-protein coupled receptor subtypes (Y1, 2, 4-6). LÄS MER

  2. 2. Functional Studies of the Neuropeptide Y System : Receptor-Ligand Interaction and Regulation of Food Intake

    Författare :Helena Åkerberg; Dan Larhammar; Rickard Malmström; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropeptide Y; G-protein coupled receptor GPCR ; site-directed mutagenesis; pancreatic polypeptide; food intake; dog; Pharmacology; Farmakologi;

    Sammanfattning : The members of the mammalian neuropeptide Y family, i.e. the peptides neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP), are all involved in regulation of food intake. In human and most other mammals they act via receptors Y1, Y2, Y4 and Y5. LÄS MER

  3. 3. Cloning and characterization of neuropeptide Y receptors of the Y1 subfamily in mammals and fish

    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; G-protein; neuropeptide Y; panacreatic polypeptide; neuropeptide Y receptor; ortholog; zebrafish; guinea pig; pseudogene; evolution; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : Neuropeptide Y (NPY) is an abundant neurotransmitter in the nervous system and forms a family of evolutionarily related peptides together with peptide YY (PYY), pancreatic polypeptide (PP) and polypeptide Y (PY). These peptides are ligands to a family of receptors that mediate a wide range of physiological effects including stimulation of appetite. LÄS MER

  4. 4. Molecular Evolution of Neuropeptide Y Receptors in Vertebrates

    Författare :Erik Salaneck; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Neuropeptide Y; Receptor; Evolution; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : The three evolutionarily related peptides neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP) are ligands to at least five G-protein coupled receptors in mammals, which are denoted by numbers. NPY has many physiological effects including stimulation of appetite and regulation of circadian rhythm and blood pressure. LÄS MER

  5. 5. Intake inhibition by neuropeptide Y

    Författare :Ahmed A Ammar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : This thesis is an attempt to elucidate some neuroendocrine concomitants to Anorexia Nervosa (AN), an eating disorder that develops in women. In particular, the thesis has examined the effect of neuropeptide Y (NPY) on food intake under experimental conditions in male and female rats. LÄS MER
