  1. 11. Spatial analysis of lipids in tissue samples applying mass spectrometry imaging

    Författare :Masoumeh Dowlatshahi Pour; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SIMS; MALDI; Mass spectrometry imaging; Lipid; ME-SIMS; Sample preparation;

    Sammanfattning : Lipids are important naturally occurring components in all living cellular organisms. They serve as the main building blocks of cellular membranes, participate in many signaling pathways and are also stored as an energy source. LÄS MER

  3. 12. Outer membrane vesicle-mediated export of virulence factors from Gram-negative bacteria

    Författare :Pramod Kumar Rompikuntal; Sun Nyunt Wai; Ann-Beth Jonsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Outer membrane vesicles; CDT; PGN; PrtV; Campylobacter jejuni; Vibrio cholerae; Aggregatibacter actinomycetemcomitans; molekylärbiologi; Molecular Biology;

    Sammanfattning : The Gram-negative, motile bacterium Campylobacter jejuni is a causative agent of food-borne gastroenteritis. Cytolethal distending toxin (CDT) is one of the important virulence factors for C. jejuni pathogenesis. It was not previously known how CDT is released from C. LÄS MER

  4. 13. Analysis of extracellular vesicles and their application in immunotherapy

    Författare :Rosanne E Veerman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Extracellular Vesicles (EVs) are nano-sized particles secreted by most, if not all, cell types. They are important mediators in intercellular communication and carry a broad array of biomolecules such as lipids, nucleic acids and proteins. LÄS MER

  5. 14. Controlling Chemistry and Membrane Proteome Composition in Nanotube-Vesicle Networks

    Författare :Brigitte Bauer; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis presents a combination of experimental and theoretical techniques to elucidate the dynamics of chemical reactions in confined biological systems and bridges the gap between biomimetic and biological systems by using cell membranes as simplified biomimetic devices. These are in turn used and analyzed to draw conclusions about the cellular membrane makeup. LÄS MER

  7. 15. Deciphering conformational ensembles and communication pathways in biomolecules

    Författare :Annie M. Westerlund; Lucie Delemotte; Erik Lindahl; Kresten Lindorff-Larsen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; Clustering; Machine learning; Network analysis; Calmodulin; KCNQ1; Biological Physics; Biologisk fysik;

    Sammanfattning : Life is constructed by small building blocks called cells. Proteins are the biomolecules within these cells which carry out different functions. Proteins located in the cell membrane, for example, allow for the transport of ions and small molecules, as well as communication, across the cell membrane. LÄS MER
