    Sammanfattning : Diabetes mellitus (DM) is a disease with epidemic proportions due to increased incidences worldwide, persistence of undiagnosed cases, uncontrolled forms of the disease, association with cardiovascular complications, and lack of definitive treatment options. In particular, type 2 DM (T2DM) is placing an enormous financial burden on worldwide healthcare systems that will increase in the futureThere is a need to develop physiological assay platforms that provide functionally relevant models of diabetes in order to accelerate the discovery of new treatments.

    Sammanfattning : High-throughput drug screening (HTS) in live cells is often a vital part of the preclinical anticancer drug discovery process. So far, two-dimensional (2D) monolayer cell cultures have been the most prevalent model in HTS endeavors. However, 2D cell cultures often fail to recapitulate the complex microenvironments of in vivo tumors. LÄS MER

  3. 3. Protein tyrosine kinases in insulin producing cells : Expression and putative importance for beta-cell function

    Författare :Charlotte Öberg-Welsh; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Protein tyrosine kinase; insulin producing cells; fetal development; VEGF; Src-family; Bsk; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : Protein tyrosine kinases are of importance for cell replication and differentiation in manysystems. The mechanisms controlling the replication and differentiation of insulin producingcells are unknown. LÄS MER

  4. 4. 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. 5. 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
