Mammalian adipogenesis regulator (Areg) cells use retinoic acid signalling to be non- and anti-adipogenic in age-dependent manner

Bart Deplancke, Julie Marie Russeil, Horia Hashimi, Daniel Alpern, Maria Litovchenko, Pernille Yde Rainer, Magda Zachara, Radiana Ferrero

Adipose stem and precursor cells (ASPCs) give rise to adipocytes and determine the composition and plasticity of adipose tissue. Recently, several studies have demonstrated that ASPCs partition into at least three distinct cell subpopulations, including th ...

Postnatal expansion of mesenteric lymph node stromal cells towards reticular and CD34(+) stromal cell subsets

Bart Deplancke, Vincent Roland Julien Gardeux, Julie Marie Russeil, Jörn Pezoldt, Guido Van Mierlo, Maria Litovchenko, Wanze Chen, Marjan Biocanin

Gut-draining mesenteric lymph nodes (LN) provide the framework to shape intestinal adaptive immune responses. Based on the transcriptional signatures established by our previous work, the composition and immunomodulatory function of LN stromal cells (SC) v ...

cis-regulatory variation modulates susceptibility to enteric infection in the Drosophila genetic reference panel

Bart Deplancke, Vincent Roland Julien Gardeux, Virginie Sandra Braman, Maroun Bou Sleiman, Riccardo Dainese, Maria Litovchenko, Michael Vincent Frochaux, Dani Osman, Brian Dennis Hollis, Tommaso Andreani

Background: Resistance to enteric pathogens is a complex trait at the crossroads of multiple biological processes. We have previously shown in the Drosophila Genetic Reference Panel (DGRP) that resistance to infection is highly heritable, but our understan ...

ASAP 2020 update: an open, scalable and interactive web-based portal for (single-cell) omics analyses

Bart Deplancke, Vincent Roland Julien Gardeux, Maria Litovchenko

Single-cell omics enables researchers to dissect biological systems at a resolution that was unthinkable just 10 years ago. However, this analytical revolution also triggered new demands in 'big data' management, forcing researchers to stay up to speed wit ...

Mitochondrial haplotypes affect metabolic phenotypes in the Drosophila Genetic Reference Panel

Johan Auwerx, Bart Deplancke, Virginie Sandra Braman, Adamantia Kapopoulou, Maria Litovchenko, Brian Dennis Hollis, Roel Paulus Josephus Bevers

The nature and extent of mitochondrial DNA variation in a population and how it affects traits is poorly understood. Here we resequence the mitochondrial genomes of 169 Drosophila Genetic Reference Panel lines, identifying 231 variants that stratify along ...

Commensal Gut Bacteria Buffer the Impact of Host Genetic Variants on Drosophila Developmental Traits under Nutritional Stress

Bart Deplancke, Virginie Sandra Braman, Maroun Bou Sleiman, Maria Litovchenko, Michael Vincent Frochaux

Eukaryotic genomes encode several buffering mechanisms that robustly maintain invariant phenotypic outcome despite fluctuating environmental conditions. Here we show that the Drosophila gut-associated commensals, represented by a single facultative symbion ...

Bayesian association scan reveals loci associated with human lifespan and linked biomarkers

Johan Auwerx, Bart Deplancke, Murielle Bochud, Hao Li, Vincenzo Sorrentino, Maria Litovchenko, Roel Paulus Josephus Bevers, Sina Rüeger, Andrea Komljenovic

The enormous variation in human lifespan is in part due to a myriad of sequence variants, only a few of which have been revealed to date. Since many life-shortening events are related to diseases, we developed a Mendelian randomization-based method combini ...

TEMPLE: analysing population genetic variation at transcription factor binding sites

Stefan Jean Laurent, Maria Litovchenko

Genetic variation occurring at the level of regulatory sequences can affect phenotypes and fitness in natural populations. This variation can be analysed in a population genetic framework to study how genetic drift and selection affect the evolution of the ...
