  1. 21. The role of the MAP- and SAP- kinase pathways in the survival, proliferation and death of Schwann cells of the injured sciatic nerve

    Författare :Lisa Mårtensson; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns alterations in signal transduction in Schwann cells as a response to nerve injury as well as their survival, proliferation and death. Enzymes and transcription factors belonging to the mitogen activated protein kinase (MAPK) and the stress activated protein kinase (SAPK) pathways were studied. LÄS MER

  3. 22. Signaling and Adhesive Mechanisms in Acute Pancreatitis

    Författare :Darbaz Awla; Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; trypsinogen activation; Acute pancreatitis; leukocyte recruitment and adhesion;

    Sammanfattning : Acute pancreatitis (AP) is an inflammatory disease with variable severity ranging from mild interstitial edematous to severe necrotizing disease. The overall mortality rate of AP is 8-9%. Specific treatment of AP is lacking which is partly related to an incomplete understanding of the basic pathophysiology behind the disease. LÄS MER

  4. 23. Aspects of proteinase-activated receptor-2: A sensor of enzymatic activity at the cell surface

    Författare :Anna-Karin Alm; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; Neurology; endometrium.; coagulation; signalling; proteinase; G-protein; cell; receptor; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Information about extracellular proteolytic activity is transduced to the cell by a transmembrane G-protein coupled receptor subfamily. These receptors are activated by proteolytic cleavage in the extracellular amino-terminal domain and are thus termed proteinase-activated receptors (PARs). LÄS MER

  5. 24. Laminin G Domains, their Receptors, and Activation of Intracellular Pathways

    Författare :Hao Yu; Klinisk minnesforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicinska vetenskaper allmänt ; General biomedical sciences; cell-matrix interaction; signaling; receptor; Basement membrane; laminin;

    Sammanfattning : Basement membranes are sheet like structures underlying epithelial, endothelial, adipocytes, muscle and peripheral nerve cells. Laminins are an important family of basement membrane proteins implicated in various biological functions through their interactions with cell surface receptors. Laminins are trimers composed of a, b and g chains. LÄS MER

  7. 25. Mechanisms of stretch-induced growth and contractile differentiation in vascular smooth muscle

    Författare :Asad Zeidan; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysiologi; Physiology; SM22a; ERK1 2; caveolae; stretch; Smooth muscle; differentiation;

    Sammanfattning : Vascular smooth muscle can adapt to increased intraluminal pressure by remodelling and hypertrophy, as seen in hypertension. The molecular mechanisms responsible for this are still incompletely characterized. LÄS MER
