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

    Författare :Mohammad Ali Khorshidi; Helene Andersson-Svahn; Håkan Jönsson; Carolina Wählby; Johan Elf; KTH; []
    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

  3. 2. Macrophage-material surface interactions

    Författare :Christina Gretzer; Göteborgs universitet; []
    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

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

    Författare :Enas Sheik-Khalil; Institutionen för laboratoriemedicin; []
    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

  5. 4. Development of multi-cellular human lung models to study inflammatory mechanisms and cell-cell interactions

    Författare :Jie Ji; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : It is well known that exposure to toxicants in the environment is associated with a wide range of health effects. The airway epithelium which forms the first line of defense, plays critical roles in the defence against inhaled particles, pathogens and toxic agents. LÄS MER

  7. 5. Too close for comfort : The role of Contact-Dependent growth Inhibition (CDI) in interbacterial competition and cooperation

    Författare :Marcus Wäneskog; Sanna Koskiniemi; Paul Rainey; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacterial interactions; cell-cell binding; contact-dependent growth inhibition; CDI; CdiB; CdiA; CdiI; outer-membrane receptor; BamA; OmpC; OmpF; extracellular toxin delivery; Toxin-Antitoxin; TA-system; persister cells; stress tolerance; stress response; rpoS; rssB; quorum sensing; multicellular behavior; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Contact-Dependent growth inhibition (CDI) was discovered in 2005 in the E. coli isolate EC93. Since then our knowledge of CDI systems and their impact on bacterial communities have increased exponentially. LÄS MER
