  1. 6. Inflammasomes : defense guardians in host-microbe defence

    Författare :Berolla Sahdo; Eva Särndahl; Bo Söderquist; Anna Norrby Teglund; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Innate immunity; inflammasome; leukocytes; cytokines; Staphylococcus aureus; Propionibacterium acnes; inflammation; infection; gene variants; polymorphism.; Biomedicin; Biomedicine;

    Sammanfattning : The inflammasomes are emerging as key regulators of the innate immune response as they response to cellular infection, tissue damage and/or stress. Activated inflammasomes provide a signalling platform for caspase-1 activation which subsequently processes the maturation of interleukin (IL)-1β and IL-18, and in addition promotes cell death, named pyroptosis.

  3. 7. Plant-seed predator interactions – ecological and evolutionary aspects

    Författare :Hannah Östergård; Johan Ehrlén; Peter Hambäck; William Kunin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; apparent competition; community context; fruit abortion; defence; host range; monophagous; offence; oligophagous; plant-animal interactions; pre-dispersal seed predation; selection; spatio-temporal variation; Biology; Biologi; Plant Ecology; växtekologi;

    Sammanfattning : Plant-animal interactions are affected by both abundance and distribution of interacting species and the community context in which they occur. However, the relative importance of these factors is poorly known. LÄS MER

  4. 8. The plasticity and geography of host use and the diversification of butterflies

    Författare :Jessica Slove Davidson; Niklas Janz; Tommi Nyman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nymphalidae; host range; phylogeny; distribution; latitude; phylogeography; local specialisation; colonisation; host shift; polyphagy; speciation; diversification; zoologisk ekologi; Animal Ecology;

    Sammanfattning : Our world is changing rapidly and factors like urbanisation, changed agricultural practices and climate change are causing losses in butterfly diversity. It is therefore of importance to understand the source of their diversity. LÄS MER

  5. 9. On airway host defence during allergic inflammation

    Författare :Anele Gela; allergologi och palliativ medicin Lungmedicin; []
    Nyckelord :Asthma; COPD; Antimicrobial peptide; chemokines; immunology;

    Sammanfattning : Asthma is a chronic inflammatory disease of the airways, affecting and disablingapproximately 300 million people worldwide. The inflammatory profile ischaracterized by infiltration of eosinophils, which are a rich source of factors thatare implicated in tissue remodeling. LÄS MER

  7. 10. Novel host defence mechanisms during bacterial infections

    Författare :Malin Elvén; Lund Dermatologi och venereologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ApoE; Complement System; TFPI-2; Antimicrobial peptides; AMP; Immunolgobulins; endotoxins; Staphylococcus aureus; Pseudomonas aeruginosa; Escheria coli;

    Sammanfattning : The immune system has evolved through thousands of years and its architecture has challenged the medical field since the first hieroglyphs and will likely continue do so. With our co-evolution with millions of other species, the complexity to treat infectious diseases has been a race in increasing speed ever since. LÄS MER
