Abstract

Neuroligins (NLs) are a family of neural cell-adhesion molecules that are involved in excitatory/inhibitory synapse specification. Multiple members of the NL family (including NL1) and their binding partners have been linked to cases of human autism and mental retardation. We have now characterized NL1-deficient mice in autism- and mental retardation-relevant behavioral tasks. NL1 knock-out (KO) mice display deficits in spatial learning and memory that correlate with impaired hippocampal long-term potentiation. In addition, NL1 KO mice exhibit a dramatic increase in repetitive, stereotyped grooming behavior, a potential autism-relevant abnormality. This repetitive grooming abnormality in NL1 KO mice is associated with a reduced NMDA/AMPA ratio at corticostriatal synapses. Interestingly, we further demonstrate that the increased repetitive grooming phenotype can be rescued in adult mice by administration of the NMDA receptor partial coagonist d-cycloserine. Broadly, these data are consistent with a role of synaptic cell-adhesion molecules in general, and NL1 in particular, in autism and implicate reduced excitatory synaptic transmission as a potential mechanism and treatment target for repetitive behavioral abnormalities.

  • In mice, ablation of nrxn1 resulted in detrimental effects on prepulse inhibition and spatial memory, and increased grooming and motor learning.

    “In mice, ablation of nrxn1 resulted in detrimental effects on prepulse inhibition and spatial memory, and increased grooming and motor learning (Etherton et al. 2009; Blundell et al. 2010)”

    The Introduction reports impaired spatial memory and increased grooming after neuroligin-1 (NL1) deletion, while the Discussion notes increased grooming in neurexin-1-deficient mice. This paper does not attribute the spatial-memory deficit to nrxn1 ablation. Its Results section also reports normal prepulse inhibition and motor learning in NL1 knockout mice, not impaired prepulse inhibition or increased motor learning. (LLM, conf=0.90)

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.
