  1. 21. Coordination of endocytosis at the synaptic periactive zone

    Författare :Emma Evergren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Synapse; endocytosis; clathrin; dynamin; amphiphysin; synapsin; intersectin; actin cytoskeleton; immunogold electron microscopy.;

    Sammanfattning : Neurons in the central nervous system communicate via specialized junctions called synapses. Neurotransmitter-filled vesicles are clustered at these junctions, where they are released in response to synaptic activity. To sustain reliable neurotransmission the synaptic vesicles are recycled locally. LÄS MER

  3. 22. Signaling capacity of ß2-integrins in relations to neutrophil motility

    Författare :Ragnhild Löfgren; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The neutrophil granulocyte is one of the most mobile cell types in the human body and represents the first line of defense against invading pathogens. Adhesion and chemotactic receptors on the cell surface work together through modulations of the cytoskeleton and thereby cause the cell to move. LÄS MER

  4. 23. Water Fluxes and Cell Migration : How Aquaporin 9 Controls Cell Shape and Motility

    Författare :Thommie Karlsson; Karl-Eric Magnusson; Roger Karlsson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Prerequisites for all modes of cell migration are cell-substratum interactions that require a sophisticated interplay of membrane dynamics and cytoskeletal rearrangement. Generally, a migrating cell is polarized with a distinct rear and front, from which it extends a wide and thin membrane protrusion- lamellipodium, small fingerlike projections- filopodia, and membrane blisters- blebs.

  5. 24. Oxidative stress and muscle weakness associated with rheumatoid arthritis

    Författare :Maarten Michiel Steinz; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Muscle weakness is a common comorbidity of several severe diseases which results in a reduced independence and quality of life and for the afflicted patients. For instance, patients with rheumatoid arthritis (RA), a disease characterized by a chronic inflammation of the joints, commonly report of muscle weakness as a complication. LÄS MER

  7. 25. Phagocytic-receptor signaling in human neutrophils

    Författare :Ragnhild Löfgren; Matthias P. Wymann; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The neutrophil granulocyte is one of the most mobile cells in the body and through a number of functions represents the first line of defense against invading pathogens. Adhesion and chemotactic receptors on the cell surface work together through modulation of the cytoskeleton, thereby enabling cell movement. LÄS MER
