    Sammanfattning : Ultrastructural studies of airway epithelium in airway disease are important for diagnosis and understanding the underlying pathology which helps clinicians to improve the patients' treatment.Airway biopsies from a 5-month old boy with respiratory problems and gastro-oesophageal reflux were studied by transmission electron microscopy (TEM).

  3. 2. Mammalian sperm flagella and cilia

    Författare :Jikui Guan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In mammals, both sperm flagella and cilia are axoneme-containing organelles. The sperm flagella are major parts of the spermatozoa that are male gametes produced in the testis from progenitor spermatogonia through a process called spermatogenesis. LÄS MER

  4. 3. The study of sensory cilia development in caenorhabditis elegans

    Författare :Evgeni Efimenko; Peter Swoboda; Philippe Bastin; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Cilia and flagella are widespread eukaryotic subcellular components that are conserved from green algae to mammals. In different organisms they function in cell motility, movement of extracellular fluids and sensory reception. LÄS MER

  5. 4. Interplay between mitochondria, primary cilium, diabetes and its complications

    Författare :Noah Moruzzi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Diabetes is one of the major health problems of the 21st century. Dysfunction of the insulin secreting pancreatic β-cell together with insulin resistance is central to the pathogenesis of type 2 diabetes mellitus (T2DM). The cause of the disease and the underlying mechanisms linking hyperglycemia to diabetes complications are still unclear. LÄS MER

  7. 5. Differential expression pattern of CEACAM1 isoforms in polarized epithelial cells : it's regulation and some functional consequences

    Författare :Ulla Sundberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :CEACAM1; adhesion; lateral localization; adherens junctions; desmosomes; primary cilia;

    Sammanfattning : The cell adhesion molecule CEACAM1 is expressed in epithelia, small vessel endothelia and leukocytes as two major, co-expressed isoforms, CEACAM1-L and CEACAM1-S, which differ in their cytoplasmic domains. CEACAM1 has been found both in cell-cell contact areas and on apical surfaces of polarized epithelial cells. LÄS MER
