Blind killing of both male and female Drosophila embryos by a natural variant of the endosymbiotic bacterium Spiroplasma poulsonii

Bruno Lemaitre, Samuel Rommelaere, Florent François Masson, Juan Camilo Paredes Escobar, Mario Gonzalo Garcia Arraez

Spiroplasma poulsonii is a vertically transmitted endosymbiont of Drosophila melanogaster that causes male-killing, that is the death of infected male embryos during embryogenesis. Here, we report a natural variant of S. poulsonii that is efficiently verti ...

Renal Purge of Hemolymphatic Lipids Prevents the Accumulation of ROS-Induced Inflammatory Oxidized Lipids and Protects Drosophila from Tissue Damage

Bruno Lemaitre, Samuel Rommelaere, Xiaoxue Li

Animals require complex metabolic and physiological adaptations to maintain the function of vital organs in response to environmental stresses and infection. Here, we found that infection or injury in Drosophila induced the excretion of hemolymphatic lipid ...

When neighbours become competitors - Autotrophic assimilation rates of individual symbionts depend on local density when Stylophora pistillata is regularly fed

Anders Meibom, Thomas Krüger, Maoz Fine

The symbiosis between dinoflagellate microalgae and their cnidarian host represents the fundamental mechanism that allows zooxanthellate corals to access the inorganic nutrient pool of the surrounding seawater and conserve and recycle nutrients within thei ...

Analyse des pesticides dans les cheveux: une nouvelle approche pour l’évaluation de l’exposition professionnelle

Christelle Oltramare

pesticides. A high number of pesticides are known as endocrine disrupting chemicals or having a supposed or verified carcinogenic effect. These toxic compounds are found in the environment, in water or in food. Once in our organism these molecules can be m ...

Genomic diversity and disease prevalence in Ugandan cattle

Stéphane Joost, Sylvie Stucki, Elia Vajana, Pierre Taberlet

Ugandan cattle are represented by three main types: the long-horned Ankole, the short-horned zebu, and the Ankole-zebu crosses called “Nganda”. In the course of the EU-funded project Nextgen, Ugandan cattle have been extensively sampled over the whole coun ...

NanoSIMS isotopic imaging - Deciphering the nature of coral-symbiont metabolic interactions

Anders Meibom, Isabelle Domart-Coulon, Christophe Kopp, Thomas Krüger, Maoz Fine

The ability of endosymbiotic Symbiodinium to fix inorganic nutrients and their translocation to the coral host is considered a key element for the growth of coral reefs in tropical coastal waters and has been a fundamental research topic for over 50 years. ...

Mechanosensory interactions drive collective behaviour in Drosophila

Dario Floreano, Pavan P Ramdya, Pawel Lichocki, Lukas Frisch, Winnie Wing Yee Tse

Collective behaviour enhances environmental sensing and decision-making in groups of animals. Experimental and theoretical investigations of schooling fish, flocking birds and human crowds have demonstrated that simple interactions between individuals can ...

From Embryo to Adult: Hematopoiesis along the Drosophila Life Cycle

Bruno Lemaitre, Elodie Julie Virginie Ramond

Studies on Drosophila hematopoiesis have thus far focused on the embryonic and larval origin of hemocytes, the fly blood cells. In this issue of Developmental Cell, Ghosh et al. (2015) identify adult hematopoietic hubs containing progenitors that can diffe ...

Clocks do not tick in unison: isolation of Clock and vrille shed new light on the clockwork model of the sand fly Lutzomyia longipalpis

Antonio Carlos Alves Meireles Filho

Background: Behavior rhythms of insect vectors directly interfere with the dynamics of pathogen transmission to humans. The sand fly Lutzomyia longipalpis is the main vector of visceral leishmaniasis in America and concentrates its activity around dusk. De ...

Editing at the crossroad of innate and adaptive immunity

Didier Trono, Priscilla Turelli

Genetic information can be altered through the enzymatic modification of nucleotide sequences. This process, known as editing, was originally identified in the mitochondrial RNA of trypanosomes and later found to condition events as diverse as neurotransmi ...
