  1. 1. Dopamine D2 and D3 receptors. Studies on transduction mechanisms and on the role of a D3 gene polymorphism

    Författare :Monika Hellstrand; Göteborgs universitet; []
    Nyckelord :dopamine; dopamine D2 receptor; dopamine D3 receptor; transduction; CHO cells; partial agonism; inverse agonism; arachidonic acid; prostaglandin E2; cAMP; haloperidol; -3-PPP; PNU-99194A; polymorphism; personality;

    Sammanfattning : The neurotransmitter dopamine has been implicated in the pathophysiology of, e.g., Parkinson s disease and schizophrenia, and dopamine receptor-active compounds are commonly employed therapeutically in these and other disorders. LÄS MER

  2. 2. Aerobic fitness and healthy brain aging : cognition, brain structure, and dopamine

    Författare :Lars Jonasson; Carl-Johan Boraxbekk; Katrine Riklund; Emrah Düzel; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aerobic exercise; VO2; working memory; executive function; freesurfer; striatum; dopamine; D2-receptors; [11C]raclopride;

    Sammanfattning : Background: Performing aerobic exercise and maintaining high levels of aerobic fitness may have positive effects on both brain structure and function in older adults. Despite decades of research however, there is still a rather poor understanding of the neurocognitive mechanisms explaining the positive effects of aerobic exercise on cognition. LÄS MER

  3. 3. Selectivity of dopamine D1 and D2 receptor agonists – A combined computational approach

    Författare :Marcus Malo; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dopamine; agonists; GPCRs; pharmacophore modeling; protein structure modeling; agonist selectivity;

    Sammanfattning : Dopamine (DA) is an endogenous neurotransmitter acting in the central nervous system. DA plays a key role in many vital brain functions such as behavior, cognition, motor activity, learning, and reward. Dopamine receptors belong to the rhodopsin like family of G-protein coupled receptors (GPCRs). LÄS MER

  4. 4. Dopamine D2 and D3 receptor-ligand interactions : molecular pharmacology and medicinal chemistry

    Sammanfattning : Schizophrenia is a group of disorders with a worldwide lifetime prevalence of 0.85%. Thefunctional outcome of the disorder seem stable from the first systematic outcome studies to thepresent day, and vary only with changes in diagnostic criteria. LÄS MER
