  1. 16. Antiphagocytosis by Yersinia pseudotuberculosis : role of the YopH target proteins

    Författare :Ming Yuan; Maria Fallman; Tommy Nilsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular biology; Cas; Fyb; mAbp1; SKAP-HOM; Yersinia pseudotuberculosis; YopH; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The enteropathogenic bacterium Yersinia pseudotuberculosis binds to β1 integrins on a host cell via its surface protein invasin. This event stimulates signal transduction to the actin cytoskeleton of the eukaryotic cell, which allows the cell to engulf the bacterium that is attached to its surface. However, the pathogen Y.

  3. 17. Adipocyte size and function in the epididymal and inguinal fat depots

    Författare :Claes Fryklund; Glukostransport och proteintrafficking; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 2 Diabetes; Adipocytes; Inguinal fat; Epididymal fat; Insulin resistance; Hypertrophy; Hyperplasia;

    Sammanfattning : Nearly 60% of the worlds adult population is projected to be overweight or obese by 2030. The prevalence of obesity- related diseases, such as type 2 diabetes (T2D), has increased markedly in the past decades. The adipose tissue plays an important role in disease progression of T2D.

  4. 18. Membrane mechanisms during exo- and endocytosis in excitable cells

    Författare :Gianvito Arpino; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Excitable cells, like endocrine cells and neurons release hormones and transmitters through exocytosis to mediate many important functions, such as stress responses, immune responses, control of blood glucose, and synaptic transmission that mediates communication between neurons in the brain. This process relies on delicate endocytic mechanisms, to retrieve vesicular membranes and proteins previously fused at the plasma membrane and thus maintains the ability of exocytosis for excitable cells.

  5. 19. Functional characterization of cellulose and chitin synthase genes in Oomycetes

    Författare :Johanna Fugelstad; Vincent Bulone; Carol Munro; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cellulose biosynthesis; chitin biosynthesis; cellulose synthase gene; chitin synthase gene; Oomycetes; Phytophthora infestans; Saprolegnia monoica; pleckstrin homology domain; Microbiology; Mikrobiologi;

    Sammanfattning : Some species of Oomycetes are well studied pathogens that cause considerable economical losses in the agriculture and aquaculture industries. Currently, there are no chemicals available that are environmentally friendly and at the same time efficient Oomycete inhibitors. LÄS MER

  7. 20. Nitric oxide modulates neutrophil function

    Författare :Tony Forslund; Per Venge; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : An important role of the neutrophils is to attack and destroy microbial intruders. In order to do so, these leukocytes must adhere to the blood vessel wall, pass through the endothelial cell layer, move through the tissues to the point of infection, ingest the intruder and destroy it.
