1. 1. 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.

3. 2. 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

4. 3. 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. 4. Peptide and GABA regulation of Peptide Hormone Release in the Drosophila Brain

7. 5. Stress and immune signaling in a Drosophila tumor model

   Författare :Dilan Khalili; Ulrich Theopold; Mirka Uhlirova; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drosophila; cancer; innate immunity; fibrosis; antimicrobial peptides; chitinase-like proteins; molekylär biovetenskap; Molecular Bioscience;

   Sammanfattning : Cancer cells contain multiple biological alterations that allow them to escape from host surveillance mechanisms. One of the mechanisms that play an essential role in host protection against tumor growth is immunity. LÄS MER
