Persistence of learning-induced synapses depends on neurotrophic priming of glucocorticoid receptors
Bibliographic record
Abstract
Significance Signal transduction upon activation of receptor tyrosine kinases by neurotrophins and nuclear receptors by glucocorticoids is essential for homeostasis. Phosphorylation (PO 4 ) is one way these receptors communicate with one another to support homeostatic reactions in learning and memory. Using a newly developed glucocorticoid receptor (GR)-PO 4 –deficient knock-in mouse, we show that consolidation of learning-induced neuroplasticity depends on both GR-PO 4 and neurotrophic signaling. Cross-talk between these pathways affects experience-dependent neuroplasticity and behavior, extending previous implications of neurotrophic priming of glucocorticoid response for adaptive plasticity to chronic stress and antidepressant response. Therefore, a disruption of cross-talk between these pathways by, for example, the misalignment of circadian glucocorticoid release and experience-dependent neurotrophic signaling may contribute to the pathophysiology of stress-related disorders.

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.
