  2. 1. Role of Inducible Nitric Oxide Synthase and Melatonin in Regulation of β-cell Sensitivity to Cytokines

    Author : Annika K. Andersson; Stellan Sandler; Nils Welsh; Décio L. Eizirik; Nils Billestrup; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; β-cell; Cyclooxygenase; Cytokine; Diabetes; IFN-γ; IL-1β; iNOS; Insulin; Melatonin; Nitric oxide; Pancreatic islets; Phospholipase D; Prostaglandin E2; Streptozotocin; Cellbiologi; Cell biology; Cellbiologi;

    Abstract : The mechanisms of β-cell destruction leading to type 1 diabetes are complex and not yet fully understood, but infiltration of the islets of Langerhans by autoreactive immune cells is believed to be important. Activated macrophages and T-cells may then secrete cytokines and free radicals, which could selectively damage the β-cells. READ MORE

  4. 2. Innate immunity in human atherosclerosis and myocardial infarction : Role of CARD8 and NLRP3

    Author : Geena Paramel Varghese; Karin Fransén; Allan Sirsjö; Liza Ljungberg; Johan Frostegård; Örebro universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atherosclerosis; Inflammasome; NLRP3; CARD8; Myocardial infarction; Endothelial cells; Polymorphism; IL-1β; Cytokines; Innate immunity; Biomedicin; Biomedicine;

    Abstract : Atherosclerosis is complex inflammatory disease of the arterial wall with progressive accumulation of lipids and narrowing of the vessel. Increasing evidence suggest that inflammation plays an important role in plaque stability and often accelerate cardiovascular events such as myocardial infarction (MI). READ MORE

  5. 3. Inflammatory cell death of human macrophages induced by Aggregatibacter actinomycetemcomitans leukotoxin

    Author : Peyman Kelk; Anders Johansson; Charels A Dinarello; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aggregatibacter actinomycetemcomitans; leukotoxin; IL-1β; caspase-1; inflammatory cell death; pyroptosis; ODONTOLOGY; ODONTOLOGI; odontologi; Odontology;

    Abstract : Aggregatibacter (Actinobacillus) actinomycetemcomitans is a bacterium mainly associated with aggressive forms of periodontitis. Among its virulence factors, a leukotoxin is suggested to play an important role in the pathogenicity. READ MORE

  6. 4. Signal transduction pathways leading to apoptosis or necrosis in insulin-producing cells and prevention of cell death using gene transfer

    Author : Johan Saldeen; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; β-cells; apoptosis; Bcl-2; p38 mitogen activated kinase; NF-kB; necrosis; sphingomyelmase; ceramide; poly ADP-ribose polymerase; nitric oxide; IL-1β; TNF-a; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Signal transduction pathways potentially involved in destruction of insulin-producing β-cells in type-l diabetes and gene transfer to prevent β-cell death were studied in vitro. Adenovirus-polylysine/DNA complexes (AdpL) or polycationic liposomes mediated high reporter gene expression in dissociated primary human, fetal porcine, rat and mouse islet cells whereas gene transfer to intact islets was less efficient.

  7. 5. Influence of inflammation and of stage of lung development on the development of neonatal lung injury

    Author : Erica Bäckström; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : premature birth; BPD; inflammation; IL-1β; lung development; gastric aspirates;

    Abstract : Bronchopulmonary dysplasia (BPD) is a major cause of mortality and long-term morbidity in prematurely born infants. Pulmonary inflammation, and abnormal alveolar and vascular development of the lung are histological characteristics of BPD. Interleukin (IL)-1β is a central cytokine in inflammation. READ MORE
