α2‐glycine receptors modulate adult hippocampal neurogenesis and spatial memory
Bibliographic record
Abstract
The α2-glycine receptors (GlyRs) play important roles during early central nervous system development. However, these receptors' possible involvement in neurodevelopmental events occurring in the adult brain remains to be explored. Adult hippocampal neurogenesis (AHN) is the process by which new granule cell neurons are added to the dentate gyrus (DG) throughout adulthood. In this study, we observed that hippocampal adult neural stem cells (ANSCs) express α2-containing GlyRs. Pharmacological inhibition of GlyRs by strychnine or picrotoxin decreased the proliferation of ANSCs, both in vivo and in vitro. Mice knockout for glra2, the gene coding for the GlyR α2 subunit, were determined to display impaired AHN, and this phenomenon was accompanied by deficits in spatial memory. These results, which reveal neurodevelopmental roles for α2-GlyRs in the adult brain, may be clinically relevant, given that a mutation in GLAR2, as well as AHN impairments, have been reported in autism spectrum disorder. © 2017 Wiley Periodicals, Inc.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
