  1. 1. Melanophore a2-Adrenoceptors

    Författare :Samuel Svensson; Susanna Cotecchia; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The present study provides new insight into the pharmacology, the signal transduction mechanisms and the molecular biology of a2-adrenoceptors (a2-ARs) in black pigment cells (melanophores) of a teleost fish, the cuckoo wrasse (Labrus ossifagus L.). LÄS MER

  3. 2. α1- and α2-Adrenoceptors in the Eye : Pharmacological and Functional Characterization

    Författare :Anna Wikberg-Matsson; Thomas Mittag; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; α1-adrenoceptor subtypes; α2-adrenoceptor subtypes; iris; ciliary body; choroid; retina; ciliary artery; Neurovetenskap; Neurology; Neurologi; Ophtalmology; oftalmiatrik;

    Sammanfattning : α1- and α2-Adrenoceptors are involved in various physiological events in the eye: blood flow regulation, aqueous humor dynamics and pupil regulation. The α1- and α2-adrenoceptors can be further subdivided into six subtypes (α1A, α1B, α1D, α2A , α2B, and α2C ). LÄS MER

  4. 3. Function of B2-adrenoceptors on alveolar macrophages

    Författare :Anita Zetterlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :A;

    Sammanfattning : B2-Agonists are very effective drugs for bronchodilatation, provide a rapid relief of symptoms in asthma, and are recommended as first line treatment, together with steroids. The relaxation of bronchial smooth muscles is a well-established effect of B-agonists, but their effects on inflammatory cells in the airways are less certain. LÄS MER

  5. 4. Blood Flow Regulation and Inflammatory Response in Experimental Models of Diabetes

    Författare :Ulrika Pettersson; Mia Phillipson; Leif Jansson; Johanna Henriksnäs; Mikael Rydén; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Islets; beta-cells; pancreas; inflammation; obesity; adipose tissue; rats; mice; leukocytes; beta3-adrenoceptors; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Type 2 diabetes is caused by defect pancreatic islet β-cells together with peripheral insulin resistance. The disease is often accompanied by obesity with associated low-grade visceral adipose tissue inflammation, which contributes to insulin resistance. LÄS MER

  7. 5. Human vascular alpha-adrenoceptors. A study of peripheral arteries and veins in vitro and in vivo

    Författare :Stig Steen; Thoraxkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : By means of a sensitive myograph and alpha-receptor subtype selective agonists and antagonists the postjunctional alpha-adrenoceptors were characterized in small omental and groin arteries and veins and in long saphenous veins obtained from 52 "healthy" adults during surgery. These vessels were found to have a mixed population of contraction mediating postjunctional alpha-receptors with a predominance of apha1-receptors in the arteries and a predominance of alpha2-receptors in the veins, although regional variations occurred.
