  1. 11. Neurosteroids Induce Allosteric Effects on the NMDA Receptor : Nanomolar Concentrations of Neurosteroids Exert Non-Genomic Effects on the NMDA Receptor Complex

    Författare :Tobias Johansson; Fred Nyberg; Pierre Le Grevès; Elisabeth Hansson; Uppsala universitet; []
    Nyckelord :Pharmaceutical pharmacology; Pharmacology; neurosteroids; NMDA receptor; NR2B subunit; ifenprodil; sigma receptor; anabolic androgenic steroids; allosteric modulation; non-genomic; Farmaceutisk farmakologi;

    Sammanfattning : The neurosteroids constitute a group of powerful hormones synthesized and acting in the central nervous system. They participate in a number of important central processes, such as memory and learning, mood and neuroprotection. LÄS MER

  3. 12. The Impact of the Neuropeptide Substance P (SP) Fragment SP1-7 on Chronic Neuropathic Pain

    Författare :Anna Jonsson; Fred Nyberg; Mathias Hallberg; James Zadina; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropathic pain; substance P SP ; SP1-7; bioactive fragments; spared nerve injury; spinal cord injury; streptozotocin-induced diabetes; allodynia; hyperalgesia; peptidomimetics; cerebrospinal fluid; spinal cord stimulation; radioimmunoassay; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : There is an unmet medical need for the efficient treatment of neuropathic pain, a condition that affects approximately 10% of the population worldwide. Current therapies need to be improved due to the associated side effects and lack of response in many patients. LÄS MER

  4. 13. Substance P Endopeptidase : Purification and Characterizataion of Enzyme Activity and Evaluation of its Function during Stressful Condition

    Författare :Krister Karlsson; Lars Oreland; Fred Nyberg; Tsukasa Sakurada; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; Substance P Endopeptidase; Neuropeptide; Central Nervous System; Purification; Drug Dependence; Heat Stress; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Sammanfattning : The purification and biochemical characterization of the substance P (SP) hydrolyzing enzyme, substance P endopeptidase (SPE), have been carried out; with subsequent orientation in neurobiological fundamental processes involved in opioid dependence, withdrawal, and heat-stress.SPE was purified from rat spinal cord, human spinal cord and cerebrospinal fluid (CSF), rat ventral tegemental area (VTA), and rat hippocampus.

  5. 14. Preproenkephalin Gene and mRNA : Studies of Structure, Function, Cocaine Responses in an Animal Model, and Genetic Association with Human Opiate Addiction

    Författare :Karl Steven LaForge; Fred Nyberg; Peter S. Eriksson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological research on drug dependence; Neuropeptides; Endogenous opioid system; Drug addiction; Heroin; Cocaine; Gene expression; Genetic association; Biologisk beroendeforskning; Biological research on drug dependence; Biologisk beroendeforskning;

    Sammanfattning : The endogenous opioid enkephalin neuropeptides are mediators of pain perception and have been implicated in human addictions. The preproenkephalin gene and its mRNA have also provided many examples of tissue- and species-specific variations in mRNA structure produced through a variety of transcriptional and post-transcriptional mechanisms.

  7. 15. CNS Targets for GH and IGF-1 : Emphasis on Their Regulation in Relation to Cognitive Processes

    Författare :Madeleine Le Grevès; Fred Nyberg; Anders Hallberg; Sigbritt Werner; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical pharmacology; Central nervous system; Growth hormone; Insulin-like growth factor-1; Receptor mRNA regulation; N-methyl-D-aspartate receptor mRNA; Morris water maze; Farmaceutisk farmakologi; Pharmaceutical pharmacology; Farmaceutisk farmakologi;

    Sammanfattning : The interest for the growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis and its role in the central nervous system (CNS) has grown during the past decade. GH has been associated with psychological functions as sleep, mood, general well-being and learning and memory. LÄS MER
