The bacterial metabolite 2-aminoacetophenone promotes association of pathogenic bacteria with flies
(2014)Bacteria contaminate insects and secrete metabolites that may affect insect behaviour and potentially fitness through unknown mechanisms. Here we show that the 'grape-like' odorant 2-aminoacetophenone (2AA), secreted by ...

Article
Challenge of Drosophila melanogaster with Cryptococcus neoformans and role of the innate immune response
(2004)We found that the ingestion of Cryptococcus neoformans by Drosophila melanogaster resulted in the death of the fly but that the ingestion of Saccharomyces cerevisiae or the nonpathogenic Cryptococcus kuetzingii or Cryptococcus ...

Article
Drosophila and the hallmarks of cancer
(2013): Cancer was the disease of the twentieth century. Today it is still a leading cause of death worldwide despite being intensively investigated. Abundant knowledge exists regarding the pathological and molecular mechanisms ...

Article
Drosophila immune priming against Pseudomonas aeruginosa is short-lasting and depends on cellular and humoral immunity
(2013)Immune responses are traditionally divided into the innate and the adaptive arm, both of which are present in vertebrates, while only the innate arm is found in invertebrates. Immune priming experiments in Drosophila ...

Article
Drosophila melanogaster as a model for human intestinal infection and pathology
(2011)Recent findings concerning Drosophila melanogaster intestinal pathology suggest that this model is well suited for the study of intestinal stem cell physiology during aging, stress and infection. Despite the physiological ...

Article
Drosophila melanogaster as a model host for studying Pseudomonas aeruginosa infection
(2009)Conservation of host signaling pathways and tissue physiology between Drosophila melanogaster and mammals allows for the modeling of human host-pathogen interactions in Drosophila. Here we present the use of genetically ...

Article
Drosophila melanogaster: A first step and a stepping-stone to anti-infectives
(2013)Following an expansion in the antibiotic drug discovery in the previous century, we now face a bottleneck in the production of new anti-infective drugs. Traditionally, chemical libraries are screened either using in vitro ...

Article
Exploiting position effects and the gypsy retrovirus insulator to engineer precisely expressed transgenes
(2008)A major obstacle to creating precisely expressed transgenes lies in the epigenetic effects of the host chromatin that surrounds them. Here we present a strategy to overcome this problem, employing a Gal4-inducible luciferase ...

Article
Human pathogenic bacteria, fungi, and viruses in Drosophila
(2014)Drosophila has been the invertebrate model organism of choice for the study of innate immune responses during the past few decades. Many Drosophila-microbe interaction studies have helped to define innate immunity pathways, ...

In vivo high-resolution magic angle spinning magnetic and electron paramagnetic resonance spectroscopic analysis of mitochondria-targeted peptide in Drosophila melanogaster with trauma-induced thoracic injury
(2016)Trauma is the most common cause of mortality among individuals aged between 1 and 44 years and the third leading cause of mortality overall in the US. In this study, we examined the effects of trauma on the expression of ...

Article
In vivo high-resolution magic angle spinning magnetic resonance spectroscopy of Drosophila melanogaster at 14.1 T shows trauma in aging and in innate immune-deficiency is linked to reduced insulin signaling
(2010)In vivo magnetic resonance spectroscopy (MRS), a non-destructive biochemical tool for investigating live organisms, has yet to be used in the fruit fly Drosophila melanogaster, a useful model organism for investigating ...

Article
In vivo high-resolution magic angle spinning proton NMR spectroscopy of Drosophila melanogaster flies as a model system to investigate mitochondrial dysfunction in Drosophila GST2 mutants
(2014)In vivo nuclear magnetic resonance spectroscopy (NMR), a non-destructive biochemical tool used for investigating live organisms, has recently been performed in studies of the fruit fly Drosophila melanogaster, a useful ...

Article
In vivo imaging of Drosophila melanogaster pupae with mesoscopic fluorescence tomography
(2008)We report a technique for fluorescence tomography that operates beyond the penetration limits of tissue-sectioning fluorescence microscopy. The method uses multi-projection illumination and photon transport description in ...

Article
Involvement of skeletal muscle gene regulatory network in susceptibility to wound infection following trauma
(2007)Despite recent advances in our understanding the pathophysiology of trauma, the basis of the predisposition of trauma patients to infection remains unclear. A Drosophila melanogaster/Pseudomonas aeruginosa injury and ...

Magnetic resonance spectroscopy of live drosophila melanogaster using magic angle spinning
(2010)High-Resolution Magic Angle Spinning (HRMAS) proton magnetic resonance spectroscopy (1H-MRS) is a novel non-destructive technique that improves spectral line-widths and allows high-resolution spectra to be obtained from ...

Magnetic resonance spectroscopy of live Drosophila melanogaster using magic angle spinning.
(2010)High-Resolution Magic Angle Spinning (HRMAS) proton magnetic resonance spectroscopy ((1)H-MRS) is a novel non-destructive technique that improves spectral line-widths and allows high-resolution spectra to be obtained from ...

Article
Mesoscopic fluorescence tomography for in-vivo imaging of developing Drosophila.
(2009)Visualizing developing organ formation as well as progession and treatment of disease often heavily relies on the ability to optically interrogate molecular and functional changes in intact living organisms. Most existing ...

Neuralized Encodes a Peripheral Membrane Protein Involved in Delta Signaling and Endocytosis
(2001)Activation of the Notch (N) receptor involves an intracellular proteolytic step triggered by shedding of the extracellular N domain (N-EC) upon ligand interaction. The ligand Dl has been proposed to effect this N-EC shedding ...

The pathogenic properties of a novel and conserved gene product, KerV, in proteobacteria
(2009)Identification of novel virulence factors is essential for understanding bacterial pathogenesis and designing antibacterial strategies. In this study, we uncover such a factor, termed KerV, in Proteobacteria. Experiments ...

Profiling early infection responses: Pseudomonas aeruginosa eludes host defenses by suppressing antimocrobial peptide gene expression
(2005)Insights into the host factors and mechanisms mediating the primary host responses after pathogen presentation remain limited, due in part to the complexity and genetic intractability of host systems. Here, we employ the ...
