  2. 6. Novel Insights into Inflammatory Disturbed Bone Remodelling

    Author : Elin Kindstedt; Pernilla Lundberg; Östen Ljunggren; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone; osteoblast; osteoclast; chemokines; CCL11; periodontitis; rheumatoid arthritis; innate lympoid cells; odontologi; Odontology; immunologi; Immunology; biology; biologi; reumatologi; rheumatology;

    Abstract : Bone is a dynamic tissue that is continuously remodelled, a process that requires equal amounts of osteoclastic bone resorption and osteoblastic bone formation. Inflammation may disturb the equilibrium and result in local and/or systemic bone loss. Negative bone mass balance occurs in several chronic inflammatory diseases, e.g. READ MORE

  4. 7. Insights into the processes preceding the onset of rheumatoid arthritis

    Author : Linda Johansson; Solbritt Rantapää Dahlqvist; Mikael Brink; Felipe Andrade; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rheumatoid arthritis; pre-symptomatic individuals; autoantibodies; anti-citrullinated protein peptides antibodies; Epstein-barr virus; neutrophil extracellular traps; periodontitis; Porphyromonas gingivalis; receptor activator of nuclear factor kappa-B ligand; reumatologi; rheumatology;

    Abstract : Rheumatoid arthritis (RA) is a chronic inflammatory disease, characterized by the production of anti-citrullinated protein antibodies (ACPA) in the majority of all patients and a persistent inflammation in the synovial tissue leading to joint destruction. The aetiology of RA remains to a large extent unknown but is believed to be a complex interplay between genetic, environmental and stochastic factors. READ MORE

  5. 8. Toll-like receptors (TLRs) and inflammatory bone modeling

    Author : Ali Kassem; Ulf Lerner; Pernilla Lundberg; Pedro Souza; Timothy Arnett; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toll-like receptor; osteoclast; osteoblast; bone resorption; bone formation; P. gingivalis; S. aureus; flagellin.;

    Abstract : Patients with inflammatory or infectious conditions such as periodontitis, peri-implantitis, osteomyelitis, rheumatoid arthritis, septic arthritis and loosened joint prosthesis display varying severity of destruction in the adjacent bone tissue. Bone loss in inflammatory diseases is considered a consequence of cytokine induced RANKL and subsequent enhanced osteoclast formation. READ MORE

  6. 9. Osteotropic cytokines : expression in human gingival fibroblasts and effects on bone

    Author : Py Palmqvist; Andersson Göran; Umeå universitet; []
    Keywords : osteoblasts; osteoclasts; fibroblasts; cytokines; IL-6; LIF; OSM; IL-4; IL-3; bone resorption; odontologi; Odontology;

    Abstract : Bone metabolism is regulated by endocrine and paracrine signalling molecules influencing bone cells in the continuously remodelling bone tissue. These molecules include a variety of osteotropic stimulatory and inhibitory cytokines. READ MORE

  7. 10. Vitamin A and Osteoporosis : Experimental and Clinical Studies

    Author : Sara Johansson; Håkan Melhus; Andreas Kindmark; Monica Lind; Göran Toss; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal medicine; vitamin A; bone; osteoporosis; Invärtesmedicin; Internal medicine; Invärtesmedicin;

    Abstract : Vitamin A in high doses is severely toxic to the rat skeleton, and the active metabolite retinoic acid (RA) can induce bone resorption in vitro. An excessive dietary intake of vitamin A has been associated with reduced bone mineral density and an increased risk of hip fracture. READ MORE
