  1. 6. Functional role of cerebrospinal fluid contacting cells in the spinal cord and hypothalamus

    Författare :Elham Jalalvand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cerebrospinal fluid-contacting (CSF-c) cells are found lining the walls of the central canal and the ventricles throughout the vertebrate phylum, but their function has remained elusive. The aim here was to investigate the physiological role of CSF-c cells in the spinal cord and hypothalamus. LÄS MER

  3. 7. Studies on lipid transport and extracellular vesicle production in Caenorhabditis elegans ciliated neurons

    Författare :Shapour Rahmani; Simon Tuck; Jonathan D. Gilthorpe; Anders Olsen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C. elegans; cilia; extracellular vesicles; tat; phospholipid translocase; P4-family ATPase;

    Sammanfattning : The cilium is a protrusion of cell membrane. Both the protein and lipid contents of cilia are different from those of other parts of the cell membrane. While the transport of proteins into and out of cilia has been intensively studied, much less is known about how the lipid content of ciliary membranes is regulated. LÄS MER

  4. 8. Vitamin A regulated neuronal regeneration and homeostasis

    Författare :Sofia Håglin; Anna Berghard; Staffan Bohm; Leif Carlsson; Ola Hermanson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Activity dependent; Adult stem cells; Ageing; CYP26B1; Homeostasis; Metaplasia; Neurogenesis; Olfactory epithelium; Regeneration; Respiratory epithelium; Retinoic acid; Sensory map; Vitamin A;

    Sammanfattning : The olfactory epithelium is a dynamic tissue maintained by continuous neurogenesis throughout life. Upon injury, neurons and other olfactory cell types are regenerated through proliferation of horizontal stem cells. Some genes that regulate vitamin A metabolism are spatially expressed in the olfactory epithelium. LÄS MER

  5. 9. Regulation and function of the Clara cell secretory protein

    Författare :Magnus Nord; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Lung Clara cells Uteroglobin Polychlorinated biphenyls Rat Mouse Hu-man Fetal development Glucocorticoids Cells; cultured Gene expression regulation CEBP Calcium Protein conformation Computer simulation Mutagenesis; site-directedCalcium binding pr;

    Sammanfattning : The Clara cell secretory protein (CCSP; also known as Polychlorinated Biphenyl-binding protein (PCB-BP) or Uteroglobin) is specifically produced and secreted into the distal airway lumen by the non-ciliated Clara cell. It is a low molecular weight homodimeric protein and binds certain metabolites of PCBs as well as progestins and calcium. LÄS MER

  7. 10. 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
