The team of researchers collaborated with colleagues from Utrecht and Trento to investigate the molecular changes that occur during the process known as synapse elimination. This developmental process sculpts and refines connections between nerve and muscle at sites known as neuromuscular junctions (NMJs). The researchers have revealed rapid and dynamic changes in new protein production within motor neurons, regulated via the process of translation. The research provides a foundation from which to explore the physiology of normal neuromuscular development and may provide clues to the pathophysiology of neuromuscular disease.
The paper has been published in the journal Science Signaling: Dynamic modulation of the motor neuron translatome during developmental synapse elimination (external website).
