- description: "Dravet Syndrome (DS) is a\nsevere neurodevelopmental disorder caused by loss of function variants in SCN1A\nwhich encodes the voltage-gated sodium channel subunit Nav1.1. We recently\nshowed that neocortical vasoactive intestinal peptide interneurons (VIP-INs)\nexpress Nav1.1 and are hypoexcitable in DS (Scn1a+/-) mice. Here,\nwe investigated VIP-IN function at the circuit and behavioral level by\nperforming in vivo 2-photon calcium imaging in awake WT and Scn1a+/-\nmice. VIP-IN and pyramidal neuron activation during behavioral transition from\nquiet wakefulness to active running was diminished in Scn1a+/-\nmice, and optogenetic activation of VIP-INs restored pyramidal neuron activity\nto WT levels during locomotion. VIP-IN selective Scn1a deletion reproduced\ncore autism spectrum disorder-related behaviors in addition to cellular- and\ncircuit-level deficits in VIP-IN function, but without epilepsy, sudden death, or\navoidance behaviors seen in the global model. Hence, VIP-INs are impaired in\nvivo and may underlie non-seizure cognitive and behavioral comorbidities in\nDS."
