Genetic manipulations of neuronal activity are a cornerstone of studies aimed to identify the functional impact of defined neurons for animal behavior. With its small nervous system, rapid life cycle, and genetic amenability, the fruit fly Drosophila melanogaster provides an attractive model system to study neuronal circuit function. In the past two decades, a large repertoire of elegant genetic...

The Caenorhabditis elegans LET-418/Mi2 plays a conserved role in lifespan regulation

Vaux, Véronique De ; Pfefferli, Catherine ; Passannante, Myriam ; Belhaj, Khaoula ; Essen, Alina von ; Sprecher, Simon G. ; Müller, Fritz ; Wicky, Chantal

In: Aging Cell, 2013, p. –

The evolutionarily conserved nucleosome-remodeling protein Mi2 is involved in transcriptional repression during development in various model systems, plays a role in embryonic patterning and germ line development, and participates in DNA repair and cell cycle progression. It is the catalytic subunit of the nucleosome remodeling and histone deacetylase (NuRD) complex, a key determinant of...

The serotonergic central nervous system of the drosophila larva: anatomy and behavioral function

Huser, Annina ; Rohwedder, Astrid ; Apostolopoulou, Anthi A. ; Widmann, Annekathrin ; Pfitzenmaier, Johanna E. R. ; Maiolo, Elena M. ; Selcho, Mareike ; Pauls, Dennis ; Essen, Alina von ; Gupta, Tripti ; Sprecher, Simon G. ; Birman, Serge ; Riemensperger, Thomas ; Stocker, Reinhard F. ; Thum, Andreas S.

The Drosophila larva has turned into a particularly simple model system for studying the neuronal basis of innate behaviors and higher brain functions. Neuronal networks involved in olfaction, gustation, vision and learning and memory have been described during the last decade, often up to the single-cell level. Thus, most of these sensory networks are substantially defined, from the sensory...
