  1. 1. Interactions between platelets and complement with implications for the regulation at surfaces

    Författare :Per H. Nilsson; Kristina Nilsson Ekdahl; John Lambris; Ian Nicholls; Berhane Ghebrehiwet; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; complement system activation; regulation ; platelets activation; regulation ; biomaterials; biocompatibility; chondroitin sulfate-A; apyrase; C1q; C3; factor H; C4BP; ADP; Biomedical Sciences; Biomedicinsk vetenskap;

    Sammanfattning : Disturbances of host integrity have the potential to evoke activation of innate immunologic and hemostatic protection mechanisms in blood. Irrespective of whether the activating stimulus is typically immunogenic or thrombotic, it will generally affect both the complement system and platelets to a certain degree. LÄS MER

  3. 2. The role of the thromboinflammatory response under hemolytic conditions : pathophysiological mechanisms and therapeutic inhibition

    Författare :Alexandra Gerogianni; Per H. Nilsson; Camilla Mohlin; Tom Eirik Mollnes; Kristina Nilsson Ekdahl; Mihály Józsi; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hemolysis; heme; thromboinflammation; biomaterials; complement inhibition; LVAD; IONPs; Biomedical Sciences; Biomedicinsk vetenskap; Immunologi; Immunology;

    Sammanfattning : In blood circulation, the complement and the coagulation cascades, together with platelets and endothelial cells form a complex network of crosstalk. When dysregulated, these interactions can lead to inflammation in combination with thrombosis (thromboinflammation) and the manifestation of pathophysiological complications. LÄS MER

  4. 3. The Origin of the Genus Flavivirus and the Ecology of Tick-Borne Pathogens

    Författare :John H.-O. Pettersson; Thomas Jaenson; Sven Bergström; Kenneth Nilsson; Mikael Thollesson; Per-Eric Lindgren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Flavivirus; Virus dating; Molecular dating; Biogeography; Ixodes ricinus; Minimum infection rate; TBE; Tick-borne encephalitis virus; Rickettsia helvetica; Anaplasma phagocytophilum; Infection prevalence; RT-PCR; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Sammanfattning : The present thesis examines questions related to the temporal origin of the Flavivirus genus and the ecology of tick-borne pathogens. In the first study, we date the origin and divergence time of the Flavivirus genus. It has been argued that the first flaviviruses originated after the last glacial maximum. LÄS MER

  5. 4. Hemiparasites in the Subarctic: Resource acquisition, growth and population dynamics

    Författare :Carin H Nilsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; population dynamics; selectivity; Phenotypic plasticity; fitness; Plant ecology; Växtekologi;

    Sammanfattning : Parasitic plants are found in nearly every major terrestrial ecosystem and can be divided into two groups, holoparasites (lacking chlorophyll) and hemiparasites (chlorophyllous). The host-parasite connection is either situated above (stem parasites) or below ground (root parasites). LÄS MER

  7. 5. Clinical and immunological aspects of IgG subclass deficiency : Predictors for the need of immunoglobulin replacement therapy

    Författare :Per Wågström; Charlotte Dahle; Sofia N. Nyström; Åsa Nilsdotter-Augustinsson; Mats Nilsson; Ola Winqvist; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunoglobulin G subclass deficiency; inflammation; lymphocytes; fatigue; co-morbidity; immunoglobulin G replacement therapy;

    Sammanfattning : Background: Predominantly antibody deficiencies (PAD) are inborn errors of immunity, and associate with increased susceptibility to infections. Life-long immunoglobulin replacement therapy (IgRT) is introduced based on Ig-levels and the frequencies and severity of infections. LÄS MER
