Heterogeneity and developmental dynamics of mammalian neocortical progenitors

Gioele La Manno, Antonio Herrera Camacho, Leila Haj Abdullah Alieh

The central nervous system develops from a pool of neural progenitors which, depending on their location and time of division, generate cells committed to differentiate into specific kinds of neurons or glia. In the last decades, the developmental neurobio ...

Preparation of Single-Somite Explants from Zebrafish Embryos

Andrew Charles Oates, Sundar Ram Naganathan

The body axis of vertebrate embryos is periodically subdivided into 3D multicellular units called somites. While genetic oscillations and molecular prepatterns determine the initial length-scale of somites, mechanical processes have been implicated in sett ...

Targeted search for scaling genes reveals matrix metalloproteinase 3 as a scaler of the dorsal-ventral pattern in Xenopus laevis embryos

Daria Korotkova

How embryos scale patterning according to size is still not fully understood. Through in silico screening and analysis of reaction-diffusion systems that could be responsible for scaling, we predicted the existence of genes whose expression is sensitive to ...

Astrocyte-targeting RNA interference against mutated superoxide dismutase 1 induces motoneuron plasticity and protects fast-fatigable motor units in a mouse model of amyotrophic lateral sclerosis

Patrick Aebischer, Bernard Schneider, Nathalie Marie Géraldine Bernard, Cylia Cloé Rochat

In amyotrophic lateral sclerosis (ALS) caused by SOD1 gene mutations, both cell-autonomous and noncell-autonomous mechanisms lead to the selective degeneration of motoneurons (MN). Here, we evaluate the therapeutic potential of gene therapy targeting mutat ...

Hunting for the wavefront: investigation of somite boundary positioning in zebrafish

Arianne Bercowsky Rama

Somitogenesis is the rhythmic and sequential formation of somites, which are tissue blocks that give rise to segmented adult body structures including the vertebrae and associated muscle. Somite formation is controlled by the segmentation clock, a populati ...

Towards engineering an artificial neural tube

Jisoo Park

In this thesis, I present a self-organizing neural tube organoid that is strikingly similar in morphology, cell-type composition, and patterning to the mouse embryonic neural tube. When exposed to a sequence of epiblast culture conditions and neural differ ...

The angiopoietin-Tie2 pathway regulates Purkinje cell dendritic morphogenesis in a cell-autonomous manner

Michele De Palma

Neuro-vascular communication is essential to synchronize central nervous system development. Here, we identify angiopoietin/Tie2 as a neuro-vascular signaling axis involved in regulating dendritic morphogenesis of Purkinje cells (PCs). We show that in the ...

Maladaptive emotion regulation traits predict altered corticolimbic recovery from psychosocial stress

Dimitri Nestor Alice Van De Ville

Background: Adaptive recovery from stress promotes healthy cognitive affective functioning, whereas maladaptive recovery is linked to poor psychological outcomes. Neural regions, like the anterior cingulate and hippocampus, play critical roles in psychosoc ...

In vitro modeling of early mouse development

Mehmet Ugur Girgin

Previous attempts to recapitulate embryogenesis in a developmentally relevant context started with aggregates composed of a few thousand ESCs, termed embryoid bodies (EB), that upon induction of differentiation reveal a surprising level of autonomous cell ...

Tail Bud Progenitor Activity Relies on a Network Comprising Gdf11, Lin28, and Hox13 Genes

Denis Duboule

During the trunk-to-tail transition, axial progenitors relocate from the epiblast to the tail bud. Here, we show that this process entails a major regulatory switch, bringing tail bud progenitors under Gdf11 signaling control. Gdf11 mutant embryos have an ...

Structurally-Informed Deconvolution Of Functional Magnetic Resonance Imaging Data

Dimitri Nestor Alice Van De Ville, Thomas William Arthur Bolton, Younes Farouj, Mert Inan

Neural activity occurs in the shape of spatially organized patterns: networks of brain regions activate in synchrony. Many of these functional networks also happen to be strongly structurally connected. We use this information to revisit the fundamental pr ...

Parkin mediates the ubiquitination of VPS35 and modulates retromer-dependent endosomal sorting

Liliane Glauser, Elpida Tsika, Darren Moore

Mutations in a number of genes cause familial forms of Parkinson's disease (PD), including mutations in the vacuolar protein sorting 35 ortholog (VPS35) and parkin genes. In this study, we identify a novel functional interaction between parkin and VPS35. W ...

Male-killing toxin in a bacterial symbiont of Drosophila

Bruno Lemaitre, Toshiyuki Harumoto

Several lineages of symbiotic bacteria in insects selfishly manipulate host reproduction to spread in a population 1 , often by distorting host sex ratios. Spiroplasma poulsonii2,3 is a helical and motile, Gram-positive symbiotic bacterium that resides in ...

In vitro modeling of complex microenvironmental regulation of stem cells

Yoji Tabata

Although stem cells hold tremendous potential for clinical applications, their in vitro manipulation remains very challenging. In vivo, stem cells reside in intricate 3D microenvironments, termed niche, in which many local and systemic extrinsic factors ar ...

Transient networks of spatio-temporal connectivity map communication pathways in brain functional systems

Jean-Philippe Thiran, Pierre Vandergheynst, Alessandra Griffa, Kirell Maël Benzi, Patric Hagmann, Alessandro Daducci, Xavier Bresson, Benjamin Ricaud

The study of brain dynamics enables us to characterize the time-varying functional connectivity among distinct neural groups. However, current methods suffer from the absence of structural connectivity information. We propose to integrate infra-slow neural ...

The importance of neuronal networks for motor rehabilitation after a stroke

Friedhelm Christoph Hummel

Every year in Europe 1.5 million patients suffer a new stroke. Despite the further developments in acute therapy with nationwide stroke units, thrombolysis, thrombectomy and post-acute neurorehabilitation, only a small proportion of patients recover to a s ...

Materials and technologies for soft implantable neuroprostheses

Stéphanie Lacour, Grégoire Courtine

Implantable neuroprostheses are engineered systems designed to restore or substitute function for individuals with neurological deficits or disabilities. These systems involve at least one uni-or bidirectional interface between a living neural tissue and a ...

Methylglyoxal, the dark side of glycolysis

Pierre Magistretti, Igor Allaman

Glucose is the main energy substrate for the brain. There is now extensive evidence indicating that the metabolic profile of neural cells with regard to glucose utilization and glycolysis rate is not homogenous, with a marked propensity for glycolytic gluc ...

ProNodal acts via FGFR3 to govern duration of Shh expression in the prechordal mesoderm

Daniel Constam

The secreted glycoprotein sonic hedgehog (Shh) is expressed in the prechordal mesoderm, where it plays a crucial role in induction and patterning of the ventral forebrain. Currently little is known about how Shh is regulated in prechordal tissue. Here we s ...

3D Reconstitution of the Patterned Neural Tube from Embryonic Stem Cells

Matthias Lütolf, Adrian Ranga

Inducing organogenesis in 3D culture is an important aspect of stem cell research. Anterior neural structures have been produced from large embryonic stem cell (ESC) aggregates, but the steps involved in patterning such complex structures have been ill def ...
