1. 1. Functional study of hemolymph coagulation in Drosophila larvae

   Författare :Zhi Wang; Ulrich Theopold; Brian Lazzaro; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; innate immunity; hemolymph coagulation; clot components; Drosophila larvae; Molecular Biology; molekylärbiologi;

   Sammanfattning : Many pathogen infections in nature are accompanied by injury and subsequent coagulation. Despite the contribution of hemolymph coagulation to wound sealing, little is known about its immune function. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

7. 5. 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
