  1. 1. Live Single Cell Imaging and Analysis Using Microfluidic Devices

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Mohammad Ali Khorshidi; KTH.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Single cell analysis; time-lapse fluorescence imaging; automated image analysis; microwell; droplet microfluidics; NK cells; single cell tracking; migration behavior analysis; cell-cell interaction; optical microscopy; image analysis; image processing; microfluidics; immune cells; tracking; counting; morphology analysis;

    Sammanfattning : Today many cell biological techniques study large cell populations where an average estimate of individual cells’ behavior is observed. On the other hand, single cell analysis is required for studying functional heterogeneities between cells within populations. LÄS MER

  2. 2. Macrophage-material surface interactions

    Detta är en avhandling från Göteborg

    Författare :Christina Gretzer; Göteborgs universitet.; Gothenburg University.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Apoptosis; biomaterials; cell-cell interactions; cell-material interactions; cytokines; differentiation; fibrinogen; hydrogen peroxide; LPS; monocytes; particles;

    Sammanfattning : Material surface-stimulated activation of the macrophage and the release of mediators has been suggested to be an important factor for inflammation and tissue regeneration around biomedical implants. Macrophage interactions with particles released from implants as well as macophage-bacteria interactions are also involved in implant loosening processes. LÄS MER

  3. 3. Effects of galectins and antibodies in HIV infection; Novel Assays

    Detta är en avhandling från Microbiology, Immunology and Glycobiology, MIG, Lund University

    Författare :Enas Sheik-Khalil; Lunds universitet.; Lund University.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV-1; galectin-1; galectin-8; neutralizing antibodies; cell-cell fusion; Microscale anisotropy assay; virus binding assay; glycosylation; gp120; Automated plaque reduction assay; CellProfiler; NeutNet;

    Sammanfattning : The high variability of the HIV envelope glycoproteins (Env), and their heavy glycan coating, contributes to the limited host immune control. Still, broadly neutralizing antibodies (bnAbs) are found in some chronically infected HIV-infected individuals, which has spurred the research on antibody-based vaccines. LÄS MER

  4. 4. Interactions between the stroma and thyroid epithelial cells of normal and malignant origin

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Thérèse Dahlman; Uppsala universitet.; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical sciences; Thyroid gland; carcinoma; collagen type I; EGF; TGF-b1; interaction; integrins; E-cadherin; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : Endocrine and locally produced factors as well as interactions between epithelial cells and the stroma important in the control of growth and function of the thyroid gland. In this study, the effects of, and mechanism(s) for, such cross-talk under some normal and pathological conditions were investigated. LÄS MER

  5. 5. Plasma membrane arabinogalactan proteins

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lars Snogerup; Lunds universitet.; Lund University.; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; arabinogalactan protein plant development cell-cell interaction plasma membrane; Plant biochemistry; Växtbiokemi;

    Sammanfattning : Arabinogalactan proteins (AGPs) are proteoglycans found at the outer side of the plasma membrane and in the extracellular matrix of plants. To be able to study the plasma membrane bound AGPs, a method using SDS-agarose gel electrophoresis (SDS-AGE) was developed to overcome the problems associated with electrophoretic separation of highly glycosylated proteins.
