Nature Releases Paper Discovering Intrinsic Cytoskeletal Oscillator Establishing Neuronal Polarity

Nature released a paper on the discovery of an intrinsic cytoskeletal oscillator that establishes neuronal polarity. The journal posted the study on 08 July 2026 according to its website. The paper is titled An intrinsic cytoskeletal oscillator establishes neuronal polarity. It reports that neurons acquire polarity by specifying one neurite as the axon whereas the others become dendrites. Using live imaging and genetic loss-of-function approaches in vivo combined with optogenetic control and local cytoskeletal perturbations in cultured neurons we uncover a soma-initiated oscillatory program that primes axon selection the authors said in the paper. The work finds periodic actin branching that depends on the actin-related protein 2/3 (ARP2/3) complex at the soma remodels a global actomyosin network thereby generating an actin wave that retracts neurites before propagating into a single neurite tip. The study shows that the neuronal soma acts as a central organiser of axon-dendrite polarity through a soma-initiated Arp2/3-driven actin oscillator. Periodic somatic actin waves remodel a global actomyosin network transiently relax myosin-II contractility at a single neurite tip and bias that neurite toward axon fate the paper said.
