  1. 1. Role of adhesion molecules and chemokines in TNF-alpha-induced leukocyte recruitment

    Författare :Xiao Wei Zhang; Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; intravital microscopy; microcirculation; inflammation; adhesion; leukocyte; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Migration of leukocytes from the circulating blood into the extravascular tissue is a key component in inflammatory reactions. Leukocyte extravasation (rolling-activation-adhesion-transmigration) is strictly coordinated by adhesion molecules and chemokines expressed on cell surfaces and in tissues. LÄS MER

  3. 2. Thrombospondin 1, an autocrine regulator in T cell adhesion and migration

    Författare :ShuShun Li; Karl-Gösta Sundqvist; Jan Holgersson; Claes Dahlgren; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; T cell; adhesion; migration; thrombospondin; Immunologi; Immunology; Immunologi; immunologi; Immunology;

    Sammanfattning : Lymphocytes, the principal cells of the immune system, perform the immune function throughout the body by their unique capacity to circulate in blood stream and lymphatic vessels and migrate in lymphoid and non-lymphoid tissues. The mechanisms regulating lymphocyte adhesion and migration, interactions with cells and components within the extracellular matrix are not fully understood. LÄS MER

  4. 3. Dendritic cells from human blood : Antigen handling and expression of adhesion molecules

    Författare :Marie Larsson; Annika Scheynius; Östergötlands Läns Landsting; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Dendritic cells are a system of professional antigen-presenting cells that initiate the immune responses. Dendritic cells are widely distributed in the body, both in nonlymphoid tissues, lymphoid tissues and fluids of the body. LÄS MER

  5. 4. Protein tyrosine kinases and the regulation of signalling and adhesion in drosophila melanogaster

    Författare :Caroline Grabbe; Ruth Palmer; Tapio Heino; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drosophila; Signalling; Adhesion; Protein Tyrosine Kinase; Development; Endocytosis; Molecular biology; Molekylärbiologi;

    Sammanfattning : In order to build a multi-cellular organism and to regulate cellular functions, cells need to communicate with each other, as well as tightly regulate their behaviour in response to environmental changes. For these purposes all eukaryotic cells express a large number of membrane spanning receptors that either themselves contain catalytic activity or via cytoplasmic effector enzymes, function to transmit “signals” from the cell exterior to induce appropriate responses within the cell.

  7. 5. Adhesion molecules and synapse remodeling during motoneuron regeneration

    Författare :Johan Zelano; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Spinal motoneurons integrate a vast synaptic input and are the final conveyors of motor commands to skeletal muscle. Motoneuron regeneration includes altered contacts between the motoneuron and several other cell types. LÄS MER
