  2. 1. Insect immunity : fractionation and characterization of some immune proteins induced by primary infections of giant silk moth pupae

    Author : Torgny Rasmuson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A potent antibacterial activity in hemolymph of giant silk moth pupae is demonstrated. The system is inducible and RNA and protein synthesis are needed for the expression of the activity. Both Gram-positive and Gram-negative bacteria were found to be susceptible. The activities could be selectively inhibited, indicating a multicomponent system. READ MORE

  4. 2. Insect immunity : Inducible antibacterial proteins from Hyalophora cecropia

    Author : Dan Hultmark; Hans Boman; Sten Hammarström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; immunologi; Immunology;

    Abstract : A powerful bactericidal activity can be induced in the hemolymph of many insects as a response to an injection of bacteria. The nature of the effector molecules of this immune response was investigated, using pupae of the Cecropia moth, Hyalophora cecropia. 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. Distribution and actions of insect tachykinin-related peptides

    Author : Åsa Winther; Peter D. Evans; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Insects; Insekter;

    Abstract : Tachykinin-related peptides (TRPs) have been identified in a number of invertebrates belonging to the mollusca, euchiurdea, crustacea and insecta. The TRPs are named after their sequence similarities and possible common evolutionary relationship to the vertebrate tachykinins. READ MORE

  7. 5. Proteomics of the Drosophila hemolymph clot and the function of transglutaminase

    Author : Christine Wilhelmsson; Ulrich Theopold; Iréne Söderhäll; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drosophila; clotting; transglutaminase; innate immunity; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Abstract : Insects rely on a fast and effective coagulation and wound response to avoid loss of body fluids and immobilize pathogens. Arthropod coagulation is in some respect equivalent to vertebrate coagulation but most factors and the regulation of coagulation systems seem not to be phylogenetically conserved. READ MORE
