1. 21. Drosophila immune responses in a model for epithelial hypertrophy

   Författare :Robert Krautz; Ulrich Theopold; Hugo Stocker; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular Biology; molekylärbiologi;

   Sammanfattning : Apoptosis, differentiation and proliferation have to be tightly balanced and thus regulated to maintain tissue homeostasis. Stress, metabolic cues, genetic variability, infections and physiological host-commensal interactions influence this balance and thus need to be integrated. Therefore, beyond the discrimination between self and non-self (i.e. LÄS MER

3. 22. Molecular characterization of the Drosophila responses towards nematodes

   Författare :Md. Badrul Arefin; Ulrich Theopold; Ioannis Eleftherianos; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila; nematodes; infection; danger situations; immune response; coagulation; apoptosis; nitric oxide; leukemia; Molecular Biology; molekylärbiologi;

   Sammanfattning : A sophisticated evolutionary conserved innate immune system has evolved in insects to fight pathogens and to restrict damage in harmful (danger) situations including cancer. A significant amount of knowledge about different infection models in Drosophila has been generated in past decades, which revealed functional resemblances and implications for vertebrate systems.

4. 23. Timing Matters : Wounding and entomopathogenic nematode infection kinetics

   Författare :Alexis Dziedziech; Ulrich Theopold; Angela Giangrande; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drosophila melanogaster; Heterorhabditis bacteriophora; Photorhabdus luminescens; entomopathogenic nematodes; worms; high-resolution microscopy; time-lapse; infection; kinetics; sepsis; septic wounding; injury; clotting; glutactin; transglutaminase; prophenoloxidase; cell death; pyroptosis; caspase; molekylär biovetenskap; Molecular Bioscience;

   Sammanfattning : Over time, insects have developed complex strategies to defend themselves against presenting threats. However, in the evolutionary arms race of survival, pathogens have adapted to quickly overcome the immune response mounted by the host. LÄS MER

5. 24. Activation of the Cellular Immune Response in Drosophila melanogaster Larvae

   Författare :Ines Anderl; Dan Hultmark; Paul Badenhorst; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; immunity; blood cells; hematopoiesis; flow cytometry; in vivo imaging; genetic screens; Tl10b; fat body; Toll signaling; molekylärbiologi; Molecular Biology;

   Sammanfattning : During the last 40 years, Drosophila melanogaster has become an invaluable tool in understanding innate immunity. The innate immune system of Drosophila consists of a humoral and a cellular component. While many details are known about the humoral immune system, our knowledge about the cellular immune system is comparatively small. LÄS MER

7. 25. Innate immune gene expression and function studied in insects and mammals

   Författare :Gang Liu; Ulrich Theopold; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mikrobiologi; Microbiology;

   Sammanfattning : Insects and mammals possess innate immune responses to effectively recognize and eliminate invading microorganisms. Insects, who share with mammals conserved molecules for immune defense, are good model systems for innate immunity studies. LÄS MER
