  2. 1. Melanization and Hemocyte Homeostasis  in the Freshwater Crayfish, Pacifastacus leniusculus

    Author : Chadanat Noonin; Irene Söderhäll; Kenneth Söderhäll; Smith Valerie; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; melanization; prophenoloxidase; caspase; hematopoiesis; thymosin; astakine; circadian rhythm; reactive oxygen species; tyrosinase; prokineticin;

    Abstract : Blood cells or hemocytes play important roles in immunity. They are a major source of many immune-related molecules such as antibodies in adaptive immunity of vertebrates and prophenoloxidase (proPO) in invertebrates. READ MORE

  4. 2. 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

  5. 3. Immunity & the butterfly : A functional genomic study of natural variation in immunity

    Author : Naomi L.P. Keehnen; Christopher W. Wheat; Brian Lazzaro; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; eco-immunology; functional genomics; transcriptomics; innate immunity; selection dynamics; melanization; phagocytosis; population genetics; Pieris napi; populationsgenetik; Population Genetics;

    Abstract : Butterflies are ubiquitous and abundant, occurring in a wide variety of environments that contain diverse microbial communities with varied pathogenic pressures. These pathogens and parasites present a constant threat to organisms, and have led to the evolution of complex and intricate immune responses. READ MORE

  6. 4. Genetic and molecular dissection of hemolymph coagulation and melanization in Drosophila melanogaster

    Author : Gawa Bidla; Ulrich Theopold; David Schneider; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Abstract : Injury to epithelial barriers puts metazoans at risk of loss of body fluid and contamination of their body by foreign particles. This risk is even exacerbated in insects, which have an open circulatory system and as a result, quickly need to seal wounds in order to keep a fairly constant internal milieu. READ MORE

  7. 5. 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
