Project description:Expression data in dSTING knockdown S2 cells and whole flies after mock or pathogenic infection
Project description:Parental flies (y1v1;P{TRiP.JF01138}attP2 and y1w*;P{Act5C-GAL4}25FO1/CyO,y+) were mated to obtain progeny with genotypes for ubiquitous DmSTING RNAi and sibling controls. 2-7 day old flies were used for all infections. 23 nl of listeria monocytogenes (strain 10403S) at 1e7 CFU/ml was injected intrathoracically. Mock inoculation was performed with PBS. Whole flies were homogenized 24 h post-infection.
Project description:<p>Viral studies of Drosophila melanogaster typically involve virus injection with a small needle, causing post-injury a wounding/wound healing response, in addition to the effects of viral infection. However, the metabolic response to the needle injury is understudied, and many viral investigations neglect potential effects of this response. Furthermore, the wMel strain of the endosymbiont bacterium Wolbachia pipientis provides anti-viral protection in Drosophila. Here we used NMR-based metabolomics to characterise the acute wounding response in Drosophila and the relationship between wound healing and the Wolbachia strain wMel. The most notable response to wounding was found on the initial day of injury and lessened with time in both uninfected and Wolbachia infected flies. Metabolic changes in injured flies revealed evidence of inflammation, Warburg-like metabolism and the melanisation immune response as a response to wounding. In addition, at five days post injury Wolbachia infected injured flies were metabolically more similar to the uninjured flies than uninfected injured flies were at the same time point, indicating a positive interaction between Wolbachia infection and wound healing. This study is the first metabolomic characterisation of the wound response in Drosophila and its findings are crucial to the metabolic interpretation of viral experiments in Drosophila in both past and future studies.</p>

Project description:A method for the long-term maintenance of germ-free flies was established using aseptic isolators. The methodology effectively and reliably yields large numbers of germ-free flies in homogeneous cultures. Germ-free flies exhibited increased lifespan (only female flies) and decreased egg production, markedly reduced fat storage, less midday sleep, and enhanced aggressiveness (male flies). Fructilactobacillus—a species of fly intestinal microbes—was re-colonized in germ-free flies, and these gnotobiotic flies were successfully maintained for numerous generations. The proteome of those flies were analyzed.
