  1. 1. Hyaluronan receptors of liver endothelial cells, their purification and characterisation

    Författare :Peter A. G. McCourt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; hyaluronan; scavenger receptors; ICAM-1; liver endothelial cells; Biokemi; Biochemistry; Biokemi; fysiologi; Physiology;

    Sammanfattning : Hyaluronan (HA) is a polysaccharide common throughout the connective tissues. and is found at low concentrations in the blood. The major site of its clearance is via an endocytic receptor on liver endothelial cells (LEC). This process is vital, as excessive serum levels of HA lead to clotting disorders and overly viscous blood. LÄS MER

  3. 2. Proteomic and Functional Analysis of In Vitro Systems for Studies of Drug Disposition in the Human Small Intestine and Liver

    Författare :Magnus Ölander; Per Artursson; Pär Matsson; Edward L. LeCluyse; Volker Lauschke; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteomics; drug disposition; ADMET; drug transport; drug metabolism; hepatotoxicity; small intestine; liver; caco-2; human hepatocytes; cryopreservation; apoptosis; liver zonation; non-parenchymal cells; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : To reach the bloodstream, an orally administered drug must be absorbed through the small intestine and avoid extensive clearance in the liver. Estimating these parameters in vitro is therefore important in drug discovery and development. LÄS MER

  4. 3. The role of Lhx2 in the hematopoietic stem cell function, liver development and disease

    Författare :Ewa Wandzioch; Leif Carlsson; Stephen A Duncan; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; liver fibrosis; liver development; Lhx2; hematopoietic stem cells; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; molecular cell biology; molekylär cellbiologi;

    Sammanfattning : During embryonic development, generation of functional organs is dependent on proper interactions between different cell types. Elucidation of the mechanisms operating during organ formation might provide insights into the origin of many pathological disorders in the adult. LÄS MER

  5. 4. Immune interactions with the liver

    Författare :Azza Karrar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Liver sinusoid; endothelial cells; apoptosis; antibodies; liver immunity; biliary cells; autoimmune liver diseases; estrogen;

    Sammanfattning : The liver has an important role in the induction of immune tolerance and can be a target for immune mediated damage. The following studies are performed to address the role of liver sinusoidal endothelial cells (LSEC) in tolerance induction and to understand some of the mechanisms involved in the pathogenesis of primary sclerosing cholangitis (PSC).

  7. 5. Mechanisms of liver allograft rejections

    Författare :Xupeng Ge; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Liver transplantation; acute rejection; antibody; biliary epithelial cell; sinusoidal endothelial cell; cholangitis; toll-like receptor;

    Sammanfattning : Liver transplantation (M) has become a standard treatment for many end-stage liver diseases. However, acute rejections still occur in about half of the liver transplant recipients even treated with a combination of different modem immunosuppressants. LÄS MER
