    Sammanfattning : Neuropeptides, such as substance P (SP) and bombesin/gastrin-releasing peptide (BN/GRP), and neurotrophins are involved in neuro-immunomodulatory processes and have marked trophic, growth-promoting and inflammation-modulating properties. The impact of these modulators in rheumatoid arthritis (RA) is, however, unclear. LÄS MER

  3. 3. Microscale Tools for Sample Preparation, Separation and Detection of Neuropeptides

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Neuropeptides; Microchip; Enhanced microdialysis; Poly dimethylsiloxane PDMS ; Electrospray ionization ESI ; Multidimensional separation; Electrochemical manipulation; Mass spectrometry MS ; Capillary electrophoresis CE ; Microdevice; Microfabrication; Micro total analysis system μ-TAS ; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Sammanfattning : The analysis of low abundant biological molecules is often challenging due to their chemical properties, low concentration and limited sample volumes. Neuropeptides are one group of molecules that fits these criteria. Neuropeptides also play an important role in biological functions, which makes them extra interesting to analyze. LÄS MER

  4. 4. Estrogen-inducible neuropeptides in the rat brain: role in focal ischemic lesions

    Författare :Annette Theodorsson; Elvar Theodorsson; A: Langmoen; Linköpings universitet; []

    Sammanfattning : Sex steroids in general and estrogens in particular – in addition to their effects on the reproductive organs – affect a large number of crucial bodily functions, including “higher” brain functions.Neuropeptides constitute the phylogenetically oldest neurotransmitter system and are currently thought to act mainly during stress, disease or injury.

  5. 5. The neuropeptides GRP and PACAP and the function of the endocrine pancreas - A study on receptor deficient mice

    Författare :Kristin Persson; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; hypoglycemia; glucagon; insulin; islet of Langerhans; diabetes; PACAP; neuropeptides; GRP; diabetologi;

    Sammanfattning : The parasympathetic nerves are important for the regulation of insulin secretion, in particular after meal intake. Apart from acetylcholine, several neuropeptides can be found in the parasympathetic nerves innervating the islets of Langerhans, including gastrin-releasing peptide (GRP) and pituitary adenylate cyclase activating polypeptide (PACAP).
