  1. 1. Innate Immune Proteins in a Crustacean Pacifastacus leniusculus

    Author : Chenglin Wu; Irene Söderhäll; petr Kopácek; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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

  2. 2. Initiation of Innate Immune Responses in the Freshwater Crayfish Pacifastacus leniusculus

    Author : Lee So Young; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; pattern recognition protein; innate immunity; crayfish; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; fysiologisk mykologi; Physiological Mycology;

    Abstract : Prophenoloxidase (proPO) is a key enzyme for generation of melanin and is activated by the proPO activating enzyme (ppA) to its active form, PO. The active ppA was purified and cloned from crayfish hemocytes and it is a typical serine proteinase containing a clip, a proline-rich, and a glycine-rich domain. READ MORE

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

    Author : Chadanat Noonin; Irene Söderhäll; Kenneth Söderhäll; Smith Valerie; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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. 4. Interaction between crayfish and some microorganisms; Effect of temperature

    Author : Gül Gizem Korkut; Chadanat Noonin; Kenneth Söderhäll; Javier Diéguez Uribeondo; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Innate immunity, which constitutes the first line of defense in vertebrates, is the only immune system that invertebrates rely on to protect themselves from pathogens. The invertebrate immune system is composed of cellular and humoral components. Cellular immunity is phagocytosis, opsonization and encapsulation. READ MORE

  5. 5. Characterisation of Some Immune Genes in the Black Tiger Shrimp, Penaeus monodon

    Author : Kallaya Sritunyalucksana; C. J. Secombes; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; fysiologisk mykologi; Physiological Mycology;

    Abstract : The molecular mechanisms of the immune system in shrimp, Penaeus monodon, are completely unknown, despite its economic importance as an aquaculture species, especially in Asia and Latin America. The genes and their gene products involved in the prophenoloxidase activating system, which is considered to be a non-self recognition and defence system in many invertebrates, have been isolated and characterised in shrimp.
