  1. 1. Spinal Acetylcholine Release : Mechanisms and Receptor Involvement

    Författare :Mahinda Kommalage; Urban Höglund; Ernst Brodin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; acetylcholine release; spinal antinociception; nicotinic receptor; serotonin; GABA; Neurovetenskap; Neurology; Neurologi;

    Sammanfattning : Impulses coming from peripheries are modified in the spinal cord and transmitted to the brain. Several neurotransmitters have been involved in the processing of impulses in the spinal dorsal horn. Acetylcholine (ACh) is one of many neurotransmitters involved in the regulation of nociception in the spinal cord. LÄS MER

    Sammanfattning : In the present study, L-tryptophan (TRP)-related disturbances in the brain in experimental hepatic encephalopathy (HE) were investigated. The endogenous NMDA-receptor agonist and L-TRP metabolite quinolinic acid (QUIN) has been suggested to be involved in the pathogenesis of HE. LÄS MER

  4. 3. Serotonin in Fear and Anxiety

    Författare :S Melker Hagsäter; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serotonin; anxiety; fear; SSRI; IBS;

    Sammanfattning : That the neurotransmitter serotonin (5-HT) has a central role in fear and anxiety is supported by numerous experimental and clinical studies. Arguably the most illustrative example is the effect of serotonergic-acting drugs, and in particular the selective serotonin reuptake inhibitors (SSRIs), in the treatment of anxiety disorders.

  7. 5. Estrogen and Serotonin – old dogs, new tricks, Implications for pancreatic beta-cell function

    Författare :Alexander Balhuizen; Celiaki och diabetes; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diabetes; Estrogen; Serotonin; Pancreatic islets; Insulin resistance; Beta-cell function; GPCR;

    Sammanfattning : Islet hormone secretion is tightly regulated by metabolic status as well as local and circulating factors. These factors can activate different receptors on the pancreatic islet cells, for instance G-protein coupled receptors (GPCRs). LÄS MER
