Abstract

We report that the oxytocin-mediated neuroprotective γ-aminobutyric acid (GABA) excitatory-inhibitory shift during delivery is abolished in the valproate and fragile X rodent models of autism. During delivery and subsequently, hippocampal neurons in these models have elevated intracellular chloride levels, increased excitatory GABA, enhanced glutamatergic activity, and elevated gamma oscillations. Maternal pretreatment with bumetanide restored in offspring control electrophysiological and behavioral phenotypes. Conversely, blocking oxytocin signaling in naïve mothers produced offspring having electrophysiological and behavioral autistic-like features. Our results suggest a chronic deficient chloride regulation in these rodent models of autism and stress the importance of oxytocin-mediated GABAergic inhibition during the delivery process. Our data validate the amelioration observed with bumetanide and oxytocin and point to common pathways in a drug-induced and a genetic rodent model of autism.

  • There is a prominent delay in the normal excitatory to inhibitory switch of GABA during postnatal development due to abnormally high levels of NKCC1 beyond P10 in Fmr1 mutant mice.

    “In particular, there is a prominent delay in the normal excitatory to inhibitory switch of GABA during postnatal development due to abnormally high levels of NKCC1 beyond P10 in Fmr1 mutant mice 108,109 .”
  • Oxytocin treatment in the embryonic period suppresses GABA-mediated excitation in mice, and these effects were blocked by infusion of an OTR antagonist.

    “Tyzio et al. (2014) showed that oxytocin treatment in the embryonic period suppresses GABA-mediated excitation in mice and that these effects were blocked by the infusion of an OTR antagonist (Tyzio et al. 2014).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
