An atomic model of the bacterial chemosensory array obtained through the synthesis of cryo-electron tomography and large-scale molecular-dynamics simulations reveals a new kinase conformation during signaling events.
Regenerating neural progenitors of the Xenopus tropicalis tail prioritize differentiation to motor neuron types earlier than proliferation, a decision partly regulated by the transcription factors Pbx3 and Meis1.
Neuronal participation in generation of motor patterns in the spinal circuits is lognormal, which is an indication of a rich diversity of activity within the mean-driven as well as the fluctuation-driven regimes.
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.
Although central nervous system (CNS) regeneration has been considered to be controlled by CNS microenvironment, CNS injury causes leading to leakage of circulating factors into CNS, which promotes CNS regeneration.
