  2. 21. Butyrophilin- and Butyrophilin-like genes and their role in epithelial cell-intraepithelial T lymphocyte cross-talk

    Author : Cristina Lebrero-Fernandez; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Butyrophilin-like Btnl ; Butyrophilin Btn ; Intraepithelial lymphocytes IELs ; Mucosal immunity; Intestinal epithelial cells; γδ T cells; Intestinal inflammation; Colon cancer; Ulcerative colitis;

    Abstract : More than 50% of our immune system is located in the gut. The intestinal epithelium, which forms an interface between the organism and the environment, harbors intraepithelial lymphocytes (IELs) that comprise a mixture of conventional αβ T cells and unconventional αβ- and γδ T cells.

  4. 22. The HDZip Class I Transcription Factors in Arabidopsis thaliana : Characterisation of HDZip Genes Involved in the Mediation of Environmental Signals

    Author : Eva Henriksson; Peter Engström; Julio Salinas; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; Plant physiology; Växtfysiologi;

    Abstract : Homeodomain leucine zipper (HDZip) proteins constitute a large family of transcription factors characterised by the presence of a DNA-binding homeodomain and an adjacent leucine zipper motif, which mediates protein-dimer formation. The HDZip genes of Arabidopsis have been divided into four classes, HDZip I-IV. READ MORE

  5. 23. Ready to pull : force transmission during vascular development

    Author : Yuanyuan Zhang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The transmission of mechanical forces controls a multitude of cellular processes such as migration, the formation of new organs, muscle contraction, and resistance to the continuous stress that blood flow exerts on the blood vessel wall. These forces are sensed and replayed at the sites of cellular adhesion to the basal membrane as well as cell-cell junctions, where protein complexes connect to the cellular cytoskeleton to relay force into the cell.

  6. 24. The dynamic envelope of a fusion class II virus : molecular reorganizations during prefusion stages of Semliki forest virus

    Author : Lars Haag; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Alphavirus; SFV; fusion; cryo-EM; formaldehyde; reorganization; cross-link; 3D reconstruction; acid pH; Pepscan; MAb; inactivation; dissociation; monoclonal antibody;

    Abstract : The aim of this study was to explore a membrane fusion mechanism, prevailing in alphaviruses and known as virus class 11 fusion. The model virus for this mechanism is Semliki Forest virus (SFV) of the alphavirus family. READ MORE

  7. 25. Applications of nanotechnology in neuroscience : functionalized superparamagnetic nanoparticles as contrast enhancers in experimental magnetic resonance imaging

    Author : Fu-Hua Wang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Magnetic resonance imaging (MRI) is a noninvasive imaging technique that helps clinicians not only to diagnose but also to plan the treatment of invasive surgery and actually treat medical conditions. Superparamagnetic iron oxide nanoparticles (SPIONs) are a family of MRI contrast agents that improves MRI sensitivity/specificity. READ MORE
