Dopamine is able to ensure that neural networks maintain critical features of their output, such as synchrony of neuron firing, by directly increasing coupling strength to ensure robust output is maintained.
The signaling ligand (p)ppGpp regulates the enzyme HPRT across species by binding to a novel class of conserved motif, yet its specificity is allosterically altered through evolution of enzyme oligomerization.
Autophagic flux assays in the nematode Caenorhabditis elegans suggest that autophagy decreases during normal aging, whereas long-lived daf-2 and glp-1 mutants maintain autophagic capacity in distinct spatiotemporal-specific manners to extend lifespan.
Experiments in C. elegans reveal how synaptotagmin and Rab3, the 'yin and yang' of synapses, control whether transmitter vesicles remain docked at the presynaptic membrane or release their contents into the synapse.
Spinal Shox2 interneurons are strongly interconnected by gap junctional coupling in a function-specific manner, which provides a mechanism for synchronization of rhythm-generating neurons and may contribute to locomotor rhythmicity.
Unbiased ChIP-seq screens and genetic knockouts of large Kruppel associated box zinc finger protein (KRAB-ZFP) clusters reveal that evolutionarily young KRAB-ZFPs play a redundant role in retrotransposon restriction in mice.
