  2. 1. Functional Studies of Some Immune Relevant Genes in a Crustacean

    Author : Haipeng Liu; Kenneth Söderhäll; Irene Söderhäll; Lage Cerenius; Ingrid Faye; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anti-LPS factor; crayfish; hemocyte; innate immunity; melanization; phenoloxidase; RNA interference; WSSV; Biology; Biologi;

    Abstract : The freshwater crayfish, Pacifastacus leniusculus, mounts a strong innate immune response against microbes such as viruses and bacteria. In this thesis, a novel RNA interference (RNAi) method mediated with histone H2A was developed and applied in crayfish hematopoietic tissue cell cultures for gene functional studies. READ MORE

  4. 2. Innate Immune Proteins in a Crustacean Pacifastacus leniusculus

    Author : Chenglin Wu; Irene Söderhäll; petr Kopácek; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 2-DE; hematopoiesis; marker protein; melaniztion inhibiting protein; proPO-system; pattern recognition protein; PGN; ficolin-like protein; Immunology; Immunologi; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Abstract : Hemocytes (blood cells) are important in the immune defense against pathogens in invertebrates. In crusteacean, the hemocytes and plasma components mount a strong innate immune response against different pathogens including bacteria and virus. READ MORE

  5. 3. Molecular and functional characterization of the insect hemolymph clot

    Author : Malin Lindgren; Ulrich Theopold; Andreas Vilcinskas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Innate immunity; hemolymph coagulation; transglutaminase; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : All metazoans possess an epithelial barrier that protects them from their environment and prevents loss off body fluid. Insects, which have an open circulatory system, depend on fast mechanism to seal wounds to avoid excessive loss of body fluids. READ MORE

  6. 4. Characterization of some molecules in the prophenoloxidase-activating and clotting systems in the freswater crayfish Pacifastacus leniusculus

    Author : Ruigong Wang; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; fysiologisk mykologi; Physiological Mycology;

    Abstract : A lipopolysaccharide- and β-1,3-glucan-binding protein (LGBP) was purified from crayfish hemocytes. LGBP has binding activity to lipopolysaccharide, curdlan (insoluble β-1,3-glucans) and laminarin (soluble β-1,3-glucans), but not to peptidoglycan. READ MORE

  7. 5. Toll-mediated cellular immune response in Drosophila melanogaster

    Author : Martin Rudolf Schmid; Dan Hultmark; Louisa Wu; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molekylärbiologi; Molecular Biology;

    Abstract : Insects are amongst the most abundant and diversified multi-cellular organisms on earth. As pollinators of the vast majority of our food crops their socio-economic value is hard to overestimate. READ MORE
