Benamer et al. Nat Commun. 2020


Myelination of parvalbumin interneurons shapes the function of cortical sensory inhibitory circuits. Benamer N, Vidal M, Balia M, Angulo MC. Nat Commun 11, 5151 (2020). https://doi.org/10.1038/s41467-020-18984-7   Abstract Myelination of projection neurons by oligodendrocytes is key to optimize action potential conduction over long distances. However, a large fraction of myelin enwraps the axons of parvalbumin-positive fast-spiking interneurons (FSI), exclusively involved in local cortical circuits....

Gallo et al. J Cell Sci. 2020


  Role of the Sec22b-E-Syt complex in neurite growth and ramification. Gallo A, Danglot L, Giordano F, Hewlett B, Binz T, Vannier C, Galli T. J Cell Sci. 2020 Sep 15;133(18):jcs247148. doi: 10.1242/jcs.247148. PMID: 32843578. Download from HAL-INSERM Abstract Axons and dendrites are long and often ramified neurites that need particularly intense plasma membrane (PM) expansion during the development of the nervous system. Neurite growth depends on non-fusogenic Sec22b-Stx1 SNARE complexes at...

  Whole-Cell Photobleaching Reveals Time-Dependent Compartmentalization of Soluble Proteins by the Axon Initial Segment. Nicholson L, Gervasi N, Falières T, Leroy A, Miremont D, Zala D, Hanus C. Front. Cell. Neurosci., 10 July 2020 | https://doi.org/10.3389/fncel.2020.00180.   By limiting protein exchange between the soma and the axon, the axon initial segment (AIS) enables the segregation of specific proteins and hence the differentiation of the somatodendritic compartment and the axonal compartment....
