  1. 11. Immune defense reactions in freshwater crayfish : Cellular components

    Författare :Charlotta Ekblom; Irene Söderhäll; Kallaya Sritunyalucksana-Dangtip; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; crustaceans; hemocytes; immunity; crayfish; proteomics; transcriptomics; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Sammanfattning : The freshwater signal crayfish, Pacifastacus leniusculus, is a well-established model for studying the immune system of invertebrates. Many important discoveries have been made in this species, among others related to the clotting reaction, hematopoiesis, the prophenoloxidase activating system, the functions of crustacean immune cells, and pathogen recognition.

  2. 12. 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

  3. 13. Identification and characterisation of five innate immune genes in the cabbage looper Trichoplusia ni

    Författare :Annika Lundström; Lage Cerenius; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mikrobiologi; Microbiology;

    Sammanfattning : When insects are infected with bacteria, they respond by producing a range of different antibacterial peptides and by activating protease cascades leading to coagulation and melanisation. Cellular defence mechanisms are also involved in killing of microorganisms through phagocytosis and encapsulation. LÄS MER

  4. 14. Trade-offs between life history traits and immune defence in the collared flycatcher Ficedula albicollis

    Författare :Dag Nordling; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Animal Ecology; zooekologi;

    Sammanfattning : This thesis examines the effects of reproductive effort on immune function and parasite resistance in breeding collared flycatchers, Ficedula albicollis. It also focuses on the role of the immune function in the trade-off between number and fitness of offspring. LÄS MER

  5. 15. Brain Stem Involvement in Immune and Aversive Challenge

    Författare :Jakob Paues; Anders Blomqvist; Finn Hallböök; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lipopolysaccharide; Lithium Chloride; anorexia; aversion; parabrachial; brain stem; melanocortin; CGRP; enkephalin; Neurobiology; Neurobiologi;

    Sammanfattning : Activation of the immune system by e.g. bacteria induces the acute-phase-response and sickness behaviour. The latter encompasses among other things fever, lethargy, anorexia and hyperalgesia. LÄS MER
