  1. 21. Novel signaling pathways : induced by bacterial toxins in eukaryotic cells

    Författare :Camilla Oxhamre; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Inflammation is the process by which the host counteracts microbes that are constantly exposing the human body. These microbes rarely cause disease, due to the effective defense mechanisms of the host immune system. Although inflammation is essential for preventing infections, it can also damage the host.

  3. 22. Regulation of B cell motility and adhesion in health and disease

    Författare :Lisa Westerberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :B cells; Migration; Adhesion; WASP; immune deficiency;

    Sammanfattning : Migration and adhesion of lymphocytes are crucial to induce an efficient immune response. These activities rely on cytoskeletal dynamics, mediated by assembly of actin and microtubuli monomers leading to changes in cell shape and signaling. LÄS MER

  4. 23. Novel findings on cellular trafficking and targeting for granule storage of neutrophil elastase, a multifunctional effector molecule of innate immunity

    Författare :Linda Källquist; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic cell; CD63; neutrophil elastase; targeting; trafficking; intracellular sorting; neutrophil; azurophil granule;

    Sammanfattning : Neutrophil elastase (NE) has important roles in innate immunity, killing pathogens and controlling the immune response; but how NE is targeted to developing granules is not understood. Therefore, the aim of this thesis was to investigate the sorting of NE. LÄS MER

  5. 24. Integration of signalling in smooth muscle caveolae

    Författare :Yulia Shakirova; Cellulär biomekanik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caveola; caveolin; detrusor; cavin; smooth muscle contractility; remodelling; NO; vascular dysfunction; smooth muscle; erectile dysfunction;

    Sammanfattning : Caveolae and lipid rafts are plasma membrane microdomains that are considered to play a role in cellular signalling. Caveolins and cavins as well as cholesterol are required for the structure and function of caveolae. The papers summarized in this thesis examine the role of caveolae in smooth muscle function.

  7. 25. Ubiquitination and Receptor Endocytosis

    Författare :Kaisa Haglund; Carl-Henrik Heldin; Ivan Dikic; Harald Stenmark; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Ubiquitination; receptor tyrosine kinase; endocytosis; Cbl; CIN85; EGFR; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : Protein ubiquitination is an evolutionary conserved mechanism that controls a wide variety of cellular functions. Polyubiquitinated proteins are generally degraded in the proteasome, whereas monoubiquitination controls various other cellular processes, including endocytosis and endosomal sorting. LÄS MER
