    Sammanfattning : Periodontitis is one of the most common adult infections. Duing bacteremia in healthy individuals or patients with chronic periodontitis, a number of oral bacteria such as Porphyromonas gingivalis encounter inflammatory cells in the blood eg. platelets, neutrophils and monocytes.

  5. 4. Regulation of fibroblast activity by keratinocytes, TGF-β and IL-1α : studies in two- and three dimensional in vitro models

    Författare :Anita Koskela von Sydow; Mikael Ivarsson; Torbjörn Bengtsson; Hans Törmä; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fibroblast; Keratinocyte; TGF-β; IL-1α; coculture; fibrosis CTGF CNN 2; dermal; organotypic culture;

    Sammanfattning : Dysregulated wound healing is commonly associated with excessive fibrosis. Connective tissue growth factor (CTGF/CCN2) is characteristically overexpressed in fibrotic diseases and stimulated by transforming growth factor-β (TGF-β) in dermal fibroblasts. Reepithelialisation and epidermal wound coverage counteract excessive scar formation. LÄS MER

  7. 5. The Role of Chlamydia pneumoniae-induced Platelet Activation in Cardiovascular Disease : In vitro and In vivo studies

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chlamydia pneumoniae; Platelet; atherosclerosis; Infection; LDL-oxidation; Percutaneous coronary intervention; Cardiovascular disease; Serotonin; Reactive oxygen species production; Pharmacology; Farmakologi;

    Sammanfattning : The common risk factors for atherosclerosis, such as obesity, high cholesterol levels, sedentary lifestyle, diabetes and high alcohol intake, only explain approximately 50% of cardiovascular disease events. It is thereby important to identify new mechanisms that can stimulate the process of atherosclerosis. LÄS MER
