High-resolution spatiotemporal analysis of single serotonergic axons in an in vitro system
Frontiers in Neuroscience, 2022 Vertebrate brains have a dual structure, composed of (i) axons that can be well-captured with graph-theoretical methods and (ii) axons that form a dense matrix in which neurons with precise connections operate.

The Role of Apoptotic Signaling in Axon Guidance
Journal of Developmental Biology, 2018 Navigating growth cones are exposed to multiple signals simultaneously and have to integrate competing cues into a coherent navigational response. Integration of guidance cues is traditionally thought to occur at the level of cytoskeletal dynamics ...

To Stick or Not to Stick: The Multiple Roles of Cell Adhesion Molecules in Neural Circuit Assembly
Frontiers in Neuroscience, 2022 Precise wiring of neural circuits is essential for brain connectivity and function. During development, axons respond to diverse cues present in the extracellular matrix or at the surface of other cells to navigate to specific targets, where they ...

Cell Reports, 2017 During brain wiring, cue-induced axon behaviors such as directional steering and branching are aided by localized mRNA translation. Different guidance cues elicit translation of subsets of mRNAs that differentially regulate the cytoskeleton, yet little ...

Mechanisms of growth cone repulsion [PDF]
F1000 Biology Reports, 2010 Research conducted in the last century suggested that chemoattractants guide cells or their processes to appropriate locations during development. Today, we know that many of the molecules involved in cellular guidance can act as chemorepellents that prevent migration into inappropriate territories. Here, we review some of the early seminal experiments

Frontiers in Molecular Neuroscience, 2021 During the establishment of neural circuitry axons often need to cover long distances to reach remote targets. The stereotyped navigation of these axons defines the connectivity between brain regions and cellular subtypes.

Actin dynamics in growth cones [PDF]
The Journal of Neuroscience, 1991 The mechanism of actin incorporation and turnover in the nerve growth cone was examined by immunoelectron microscopy and low-light-level video microscopy of cultured neurons injected with biotin-labeled actin or fluorescently labeled actin. We first determined the sites of actin incorporation into the cytoskeleton of growth cones by immunoelectron ...

Frontiers in Physiology, 2019 Cytoplasmic Actin Gamma 1 (ACTG1) gene variant are autosomal dominant and can cause CNS anomalies (Baraitser Winter Malformation Syndrome; BWMS). ACTG1 anomalies in offspring include agenesis of the corpus callosum (ACC) and neuronal heterotopia which ...

Translational regulation in growth cones [PDF]
Current Opinion in Genetics & Development, 2011 Axonal growth cones (GCs) steer in response to extrinsic cues using mechanisms that include local protein synthesis. This adaptive form of gene regulation occurs with spatial precision and depends on subcellular mRNA localisation. Recent genome-wide studies have shown unexpectedly complex and dynamically changing mRNA repertoires in growing axons and ...

Neuronal Growth Cone Size-Dependent and -Independent Parameters of Microtubule Polymerization
Frontiers in Cellular Neuroscience, 2018 Migration and pathfinding of neuronal growth cones during neurite extension is critically dependent on dynamic microtubules. In this study we sought to determine, which aspects of microtubule polymerization relate to growth cone morphology and migratory ...
