  1. 1. The role of platelets in whole blood coagulation

    Författare :Sofia Ramström; Nils Olav Solum; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The body's first line of defence against bleeding is the platelets, small cell fragments with multiple roles in the coagulation process. The platelets are patrolling our blood vessels, looking for damage in the endothelial cell layer, to which they attach and transform, recruit more platelets and assemble the plasma coagulation proteases on their surfaces.

  2. 2. Tissue Factor regulation, signaling and functions beyond coagulation with a focus on diabetes

    Författare :Desireé Edén; Agneta Siegbahn; Sofia Ramström; Uppsala universitet; []
    Nyckelord :Tissue factor; diabetes; cell signaling; coagulation; beta cells; adipocytes; apoptosis; lipolysis; micro RNA; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Background: Tissue factor (TF) is a 47 kDa transmembrane glycoprotein best known for initiating the coagulation cascade upon binding of its ligand FVIIa. Apart from its physiological role in coagulation, TF and TF/FVIIa signaling has proved to be involved in diseases such as diabetes, cancer and cardiovascular diseases. LÄS MER

  3. 3. Formation and Relevance of Platelet Subpopulations

    Författare :Anna Södergren; Sofia Ramström; Karin Öllinger; Riitta Lassila; Linköpings universitet; []

    Sammanfattning : Platelets are important players in the hemostatic system, acting as guardians of vessel integrity. When they come across a breach in the vessel wall, they quickly adhere to the damaged surface, secrete activating and adhesive compounds from their secretory granules, recruit additional platelets into a growing platelet plug and support the action of the coagulation system.

  4. 4. The role of platelet thrombin receptors PAR1 and PAR4 in platelet activation

    Författare :Karin Vretenbrant Öberg; Tomas Lindahl; Sofia Ramström; Johan Heemskerk; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Platelets play a pivotal role in coagulation and haemostasis. Their most prominent task is to seal damaged blood vessels by the formation of a platelet plug at the damaged area. Once the injury is covered, platelets retract the coagulum to close the wound and allow the blood to flow freely in the vessel. LÄS MER
