  1. 16. 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

  3. 17. 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

  4. 18. Bacillus Cereus. Adhesion Ability to Biological and Non-Biological Surfaces, Enterotoxins, Characterization

    Författare :Annika Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; characterization; Bacillus cereus; spores; adhesion; enterotoxin;

    Sammanfattning : The organism investigated in this thesis was Bacillus cereus, which is important as a food spoilage organism and as a pathogen. The adhesion of endospores to and the removal of endospores from siliconized glass surfaces were investigated to increase the knowledge of adhesion mechanisms and to improve the removal of endospores from surfaces.

  5. 19. 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. 20. Granulocyte Adhesion to Matrix Proteins and the Effect on the Release of Granule Proteins : Development of a Simple Method and its Application in Experimental and Clinical Studies

    Författare :Xiaoyan Xu; Joachim Lundahl; Uppsala universitet; []
    Nyckelord :Medical sciences; Eosinophils; Neutrophils; Adhesion; Release of ECP; Extracellular matrix proteins; Granulocytes; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

    Sammanfattning : Granulocyte adhesion and release of their granule proteins are key steps during selective accumulation of a certain cell to an inflammatory site. Eosinophils are specifically recruited to sites of allergic inflammation and parasitic infection, whereas neutrophil influx predominates in bacterial infection and rheumatoid arthritis. LÄS MER
