  3. 12. CD47–SIRPα : an interaction of importance for bone cell differentiation

    Författare :Cecilia Koskinen; Pernilla Lundberg; Per-Arne Oldenborg; Riku Kiviranta; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CD47; SIRPalpha; osteoblast; osteoclast; SHP-2; Akt2; cell research; cellforskning;

    Sammanfattning : Bone tissue is continuously remodeled by bone-forming osteoblasts and bone-resorbing osteoclasts, in processes tightly regulated by hormones, cytokines and growth factors. CD47, a ubiquitously expressed protein, and one of its ligands, signal-regulatory protein alpha (SIRPα), are two cell-surface proteins belonging to the immunoglobulin (Ig)-superfamily. LÄS MER

  4. 13. Influences of in vivo and in vitro loading on the proteoglycan synthesis of articular cartilage chondrocytes

    Författare :Mikko Lammi; Markku Tammi; Jukka Finne; Tim Hardingham; Finland Kuopio University of Kuopio Department of Anatomy; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Articular cartilage; proteoglycans; loading; stress; hydrostatic pressure; biokemi; Biochemistry; cell research; cellforskning; molekylärbiologi; Molecular Biology; ortopedi; Orthopaedics;

    Sammanfattning : In this study, the biosynthesis of proteoglycans (PGs) was examined in articular cartilage of canine hip joint after long-distance running experiment and in bovine chondrocyte cultures during in vitro loading with hydrostatic pressure. In addition, new assays were developed for more sensitive quantitation of glycosaminoglycans (GAGs) and PGs. LÄS MER

  5. 14. Heparan Sulfate in the Amyloidosis and Inflammation of Alzheimer’s Disease

    Författare :Paul O'Callaghan; Xiao Zhang; Lars Lannfelt; Jeremy Turnbull; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; amyloidosis; amyloid-β; apolipoprotein E; astrocytes; glia; heparanase; heparan sulfate; heparan sulfate proteoglycans; microglia; neuroinflammation; Geriatrics; Geriatrik; Cellforskning; Cell Research; Neuroscience; Neurovetenskap; Pathology; Patologi;

    Sammanfattning : Alzheimer’s disease (AD) is a neurodegenerative disorder, with extensive evidence implicating the misfolding, aggregation and deposition of the amyloid-β (Aβ) peptide as central to the pathogenesis. Heparan sulfate (HS) is an interactive glycosaminoglycan, attached to core proteins as HS proteoglycans (HSPGs). LÄS MER

    Författare :Chengjuan Qu; Mikko Lammi; Heikki Helminen; Juha Töyräs; Anna-Marja Säämänen; Finland Kuopio University of Kuopio Anatomy Department of Biomedicine; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cartilage; Chondrocytes metabolism; Chondroitin sulfates; Glycosaminoglycans; Osteoarthritis; Proteoglycans; Glucosamine; Sulfation; Biochemistry; biokemi; cellforskning; cell research; Orthopaedics; ortopedi;

    Sammanfattning : Glucosamine (GlcN) and glucosamine sulfate (GS) have been used to treat the patients with osteoarthritis(OA) as a disease-modifying agent. Previousin vitro studies have focused on the effects of GlcN or GSon cartilage metabolism, whereas in vivo studies have investigated their potential for the treatment of OA. LÄS MER
