The universal bacteria cell wall component peptidoglycan impacts the egg-laying behavior of infected Drosophila females by directly modulating the activity of few brain octopaminergic neurons.
A molecular mechanism that involves highly conserved transcription factors enables cholinergic motor neurons of the nematode Caenorhabditis elegans to become and remain functional.
Laser-ablating neurons of a single genetic class reveals that Dbx1-derived interneurons comprise core respiratory rhythmogenic and premotor circuits and provides quantitative cellular parameters that govern network functionality
The 'missing' class of Caenorhabditis elegans excitatory motor neurons, AS, contribute to propagation and coordination of body waves, integrating information from, and feeding back to premotor interneurons byelectrical signaling.
Actin is incorporated into the thin-filament arrays of skeletal muscle sarcomeres in discrete steps, and Fhos, the Drosophila homolog of FHOD-family formins, is an essential player in the process.
