Christophe Leterrier, leader of the NeuroCyto ATIP team, wrote a Spotlight in the Journal of Cell Biology highlighting a nice recent paper from the group of Pei-Lin Cheng in Taiwan. In this article, Lee et al. showed how degradation of the chloride transporter NKCC1 by proteasomes anchored at the AIS have a key role in lowering the intracellular chloride concentration, leading to the perinatal reversal of GABA effect from excitatory to inhibitory.
