  1. 1. Striatal adenosine A2A receptors

    Detta är en avhandling från Stockholm : Karolinska Institutet, false

    Författare :Per Svenningsson; Karolinska Institutet.; Karolinska Institutet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caffeine; adenosine; A2A receptors; dopamine receptors; striatum; basal ganglia; immediate early genes; c-fos; NGFI-A; DARPP-32; in situ hybridization;

    Sammanfattning : The nucleoside adenosine exerts a modulatory action in the central nervous system by activating G-protein coupled receptors. Four such receptors are cloned and pharmacologically characterized: A1, A2A, A2B and A3. Caffeine, the most widely consumed psychostimulant, acts as an adenosine receptor antagonist predominantly on the first two. LÄS MER

    Sammanfattning : A balanced tear film is essential for a healthy ocular surface. Insufficient tear production may result in dry eye, a common disorder in the elderly population. Dry eye causes significant discomfort in the patients and may lead to visual impairment and ocular infections. LÄS MER

  4. 4. Studies of nucleotide receptors-induced calcium response in glomerular mesangial cells and afferent arterioles

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Antonio M. Gutiérrez; Uppsala universitet.; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; mesangial cells; nucleotide receptors; purinoceptors; desensitization; afferent arterioles; ATP; UTP; adenosine; protein phosphatases; calcium; Fysiologi och anatomi; MEDICINE Physiology and pharmacology; MEDICIN Fysiologi och farmakologi; Physiology; fysiologi;

    Sammanfattning : It is known that intracellular calcium concentration ([Ca2+]i) changes in rat glomerular mesangial cells (GMC) and rabbit afferent arterioles (AA) in response to extracellular nucleotides. We studied the nucleotide-induced calcium response in cultured GMC and AA. LÄS MER

  5. 5. Adenosine A2A and ATP receptors in PC12 cells

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Författare :Giulia Arslan; Karolinska Institutet.; Karolinska Institutet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PC12 cells; A2A receptors; ATP receptors; NGF; MAPK; Hypoxia; Cyclic AMP;

    Sammanfattning : PC12 cells, originally isolated from a rat pheochromocytoma, are widely used to study receptor pharmacology and nerve cell differentiation. They are the neoplastic counterpart of adrenal chromaffin cells, but upon treatment with NGF they acquire a neuronal phenotype. LÄS MER
