    Sammanfattning : A balanced tear film is essential for a healthy ocular surface. Insufficient tear production may result in dry eye, a common disorder in the elderly population. Dry eye causes significant discomfort in the patients and may lead to visual impairment and ocular infections. LÄS MER

  3. 2. Adhesion Dependent Signals : Cell Survival, Receptor Crosstalk and Mechanostimulation

    Författare :Anjum Riaz; Staffan Johansson; Bengt Hallberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Integrins; Signal transduction; Protein kinase B; Akt; PI3K; Heparanase; ROS; Mechanosignalling; Molekylär cellbiologi; Molecular Cellbiology; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi; Cellforskning; Cell Research;

    Sammanfattning : The integrin family of cell surface receptors is evolutionary conserved and found in all multicellular animals. In humans 8-alpha and 18-beta integrins are non-covalently associated into 24 dimers. Integrins mediate cell-extracellular matrix and cell-cell interactions and participate in cell signalling.

  4. 3. Imaging-based methods for NK cell studies at the single-cell level

    Författare :Quentin Verron; Björn Önfelt; Niklas Sandström; Michael Dustin; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; NK cells; microscopy; single-cell; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : The immune system provides defense against infectious agents such as viruses, bacteria and parasites. Besides eliminating extracellular agents, the immune system also constantly monitors our own cells for signs of transformation, including tumor development and virus infection. LÄS MER

  5. 4. Exploring Cellular Dynamics : From Vesicle Tethering to Cell Migration

    Författare :Parham Ashrafzadeh; Johan Kreuger; Jonas Fuxe; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; cancer; cell migration; exocyst complex; exocytosis; FGD5; lipid rafts; plasma membrane; receptor trafficking; VEGFR2;

    Sammanfattning : Cells in the body communicate with each other in order to cooperate efficiently. This communication is in part achieved by regulated secretion of signaling molecules, which when released from a cell may activate receptors present at the plasma membrane of an adjacent cell. Such signals affect both cell fate and behavior. LÄS MER

  7. 5. New Approaches for Chemical Analysis of Single Cells and Vesicles

    Författare :Johan Dunevall; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrochemistry; Analytical chemistry; Chemistry; Exocytosis; Catecholamines;

    Sammanfattning : Exocytosis is the major cell-to-cell communication process in the nervous system, involving the conversion of an electrical signal (e.g. action potential) to a chemical one. Signaling molecules like neurotransmitters, hormones and/or peptides are stored in vesicles inside the cell. LÄS MER
