Abstract: Malgre sa simplicite anatomique, le nematode Caenorhabditis elegans (C. elegans) est un organisme multicellulaire complexe. Au travers des etudes qui ont contribue a une meilleure comprehension de certains aspects de la physiologie du ver, nous presentons dans cette revue les elements concernant les bases cellulaires et moleculaires des interactions entre C. elegans et son environnement, notamment les capacites sensorielles, l’horloge biologique interne qui gouverne la vitesse de developpement du ver, et certains facteurs controlant sa longevite. Nous exposons aussi brievement les resultats tres recents qui demontrent l’existence d’une immunite innee chez ce nematode. Finalement, nous soulignons certaines methodologies recentes qui ouvrent la voie a des etudes fonctionnelles systematiques chez C. elegans.

TL;DR: How members of two multigene families—nuclear hormone receptors and G protein–coupled receptors—perceive and translate environmental cues to regulate diapause stages in the larval and adult reproductive stages, respectively are revealed.

Un Nématode Prix Nobel : Caenorhabditis elegans
J. Savel,F. Clostre +1 more
TL;DR: The Nematode Caenorhabditis elegans (C. elegans) is an established model increasingly used for studying human disease pathogenesis as discussed by the authors, which can give new insights on the cellular and molecular mechanisms that are altered in some neurodegenerative diseases like Duchenne's muscular dystrophy, Huntington's disease and Alzheimer's disease.

TL;DR: It is found that genes of similar functions are clustered in distinct, multi-megabase regions of individual chromosomes; genes in these regions tend to share transcriptional profiles.

Increased dosage of a sir-2 gene extends lifespan in Caenorhabditis elegans
TL;DR: In this paper, the lifespan of C. elegans strains containing duplications of chromosomal regions was surveyed and it was shown that a duplication containing sir-2.1-the SIR2 gene most homologous to yeast-confers a lifespan that is extended by up to 50%.

C. elegans Locomotory Rate Is Modulated by the Environment through a Dopaminergic Pathway and by Experience through a Serotonergic Pathway
TL;DR: The basal and enhanced slowing responses are distinct and separable neuromodulatory components of a genetically tractable paradigm of behavioral plasticity.

TL;DR: The developing animal appears to contain a regulatory system that monitors mitochondrial activity early in life and, in response, establishes rates of respiration, behavior, and aging that persist during adulthood.
