Test whether under OXTR antagonist or Oxtr LOF that abolishes OXTR-class social-recognition / anxiolysis attribution, oxytocin still retains social-memory or anxiolytic phenotype
Oxytocin is framed as supporting social recognition and anxiolysis through OXTR-class attribution, yet that framing is often assumed to exhaust the phenotype. This discussion asks whether residual exogenous oxytocin social-memory or anxiolysis under an OXTR antagonist or Oxtr LOF that abolishes OXTR-class social-recognition / anxiolysis attribution still requires a path beyond OXTR-class attribution.
Claim
On a matched social-recognition / anxiolysis panel ± exogenous oxytocin ± OXTR antagonist or Oxtr genetic LOF (e.g. L-368,899, site-specific OXTR antagonist, or Oxtr-/- / cell-type Oxtr ablation) titrated so the block abolishes OXTR-class social-recognition / anxiolysis attribution, plus social-memory or anxiolytic endpoint: under that OXTR-abolish condition, residual oxytocin social-memory / anxiolytic phenotype remains ≥50% of the oxytocin without-OXTR-abolish arm on the same panel (named comparator = oxytocin without-OXTR-abolish arm under matched panel) — assumption-kill / oxtr-insufficiency.
Why it matters
Ferguson maps OXTR activation in medial amygdala as necessary and sufficient for mouse social recognition; Takayanagi / Hung / Matsumoto map Oxtr LOF social-discrimination and allogrooming deficits. P23 asks whether residual exogenous oxytocin social-memory / anxiolysis under an OXTR antagonist or Oxtr LOF that abolishes OXTR-class attribution still requires a path beyond OXTR-class attribution — oxtr-insufficiency assumption-kill. Distinct from P15 (BPC residual-FBXO22), P16 (LKKTETQ-Cc), P17 (MOTS-c/folate), P18 (SS-31/ROS-scavenger), P19 (ARA290/IRR), P20 (Semax/TrkB; oxytocin≠Semax; OXTR≠TrkB), P21 (Selank/GABA; oxytocin≠Selank; OXTR≠GABA), and P22 (Dihexa/c-Met; oxytocin≠Dihexa; OXTR≠c-Met); NOT FOXO4×LOF; skip-list unused; orthosteric_drift=false. Soft-claims: discussion — matched residual-under-OXTR-abolish H2H UNKNOWN; PRIOR_ART PARTIAL (necessity AGAINST residual); soft-complete empty ≠ novelty / ≠ failure; P1–P22 ≠ proof.
Mechanism sketch
oxtr-insufficiency assumption-kill: Ferguson shows OXTR MeA necessary and sufficient for social recognition LITERATURE (OT antagonist; OT peptide-KO rescue requires intact OXTR — necessity AGAINST residual); Takayanagi shows Oxtr(-/-) social discrimination deficits LITERATURE; Hung shows Oxtr mossy-cell social discrimination LITERATURE; Matsumoto shows Oxtr indispensable allogrooming LITERATURE — none score residual exogenous oxytocin under an OXTR antagonist / Oxtr LOF that abolishes OXTR-class social-recognition / anxiolysis attribution on the same panel. Promoted Tsai (PMID 35811321; out of public prior_art ≤4) shows PVH OXT-neuron SRM enhance BLOCKED by L-368,899 into dCA2 — stronger necessity H2H AGAINST residual; not residual-positive. OXTR-class social-recognition / anxiolysis framing is the class PRIOR under kill — PRIOR necessity / phenotype ≠ matched residual-positive H2H under OXTR-abolish. P23 scores residual social-memory / anxiolysis under OXTR antagonist or Oxtr LOF that first abolishes OXTR-class attribution, on the same panel ± oxytocin ± OXTR-abolish (prefer MeA / mossy-cell / dCA2 circuit or slice block-QC with OXTR antagonist / Oxtr ablation before new animal social-recognition / anxiolysis panels). Explicitly NOT FOXO4×LOF (SERIES_FROZEN); NOT BPC-157 / FBXO22 / VEGFR2 / OpenLabs skip-list 8e5ba06c or 7db12286 orthosteric dialect; NOT P15 residual-FBXO22; NOT P16 LKKTETQ under G-actin Cc; NOT P17 MOTS-c residual under folate repletion; NOT P18 SS-31 residual under matched ROS-scavenger; NOT P19 ARA290 residual under hematopoietic-matched EPO; NOT P20 Semax residual under TrkB antagonist / BDNF neutralize (oxytocin ≠ Semax; OXTR ≠ TrkB); NOT P21 Selank residual under GABA-A/BDZ match (oxytocin ≠ Selank; OXTR ≠ GABA); NOT P22 Dihexa residual under HGF/c-Met block (oxytocin ≠ Dihexa; OXTR ≠ c-Met). Soft-complete empty ≠ novelty / ≠ failure.

Actionable limitations
- Do not treat P1–P22 as proving P23 — Ferguson/Takayanagi/Hung/Matsumoto necessity priors are not a residual-under-OXTR-abolish H2H; Tsai L-368899 block leans AGAINST residual; soft-complete empty ≠ demonstrated residual phenotype; do not invent residual when UNKNOWN.
- Skip-list / series distinctness (critical) — do not freeze or collapse to OpenLabs 8e5ba06c / 7db12286 BPC orthosteric dialect, P15 residual-FBXO22, P16 LKKTETQ-Cc, P17 MOTS-c/folate, P18 SS-31/ROS-scavenger, P19 ARA290/IRR, P20 Semax/TrkB (oxytocin≠Semax; OXTR≠TrkB), P21 Selank/GABA (oxytocin≠Selank; OXTR≠GABA), or P22 Dihexa/c-Met (oxytocin≠Dihexa; OXTR≠c-Met); orthosteric_drift=false; REJECT if claim drifts to BPC/FBXO22/VEGFR2 or LKKTETQ/Tβ4 sequestration or MOTS-c/folate or SS-31/cardiolipin/MitoTEMPO or ARA290/IRR or Semax/TrkB/BDNF or Selank/GABA/BDZ or Dihexa/HGF/c-Met; NOT FOXO4×LOF (SERIES_FROZEN).
- Ferguson/Takayanagi/Hung/Matsumoto lack an exogenous-OT residual arm under OXTR-abolish on the same panel; incomplete OXTR block / OXTR-class attribution not abolished / no residual to score / block-QC failure leave the test inconclusive rather than refuted; do not misread OT peptide-KO rescue (11588199) as Oxtr-LOF residual; no dosing; reviews ≠ experimental anchors.

Ablate
- remove matched social-recognition / anxiolysis panel ± exogenous oxytocin ± OXTR antagonist or Oxtr LOF under OXTR-abolish that first abolishes OXTR-class social-recognition / anxiolysis attribution, then scores residual oxytocin social-memory / anxiolysis: Without the OXTR-abolish × residual H2H, separate Ferguson necessity LITERATURE, Takayanagi Oxtr LOF LITERATURE, Hung mossy-cell LITERATURE, and Matsumoto allogrooming LITERATURE cannot show oxtr-insufficiency of residual oxytocin under OXTR-abolish.
- remove OXTR-abolish gate plus oxytocin without-OXTR-abolish arm as the named residual comparator (vs Ferguson/Takayanagi/Hung/Matsumoto necessity-alone / OXTR-class attribution-alone / Tsai L-368899 block-alone): Without the OXTR-abolish gate and oxytocin without-abolish comparator under the same block condition, the card collapses into Ferguson/Takayanagi/Hung/Matsumoto necessity prior or generic OXTR-class framing and loses oxtr-insufficiency contrast.

On the pre-registered matched social-recognition / anxiolysis panel ± exogenous oxytocin ± OXTR antagonist or Oxtr genetic LOF (e.g. L-368,899, site-specific OXTR antagonist, or Oxtr-/- / cell-type Oxtr ablation) where OXTR-abolish abolishes OXTR-class social-recognition / anxiolysis attribution, residual oxytocin social-memory / anxiolytic phenotype is <50% of the oxytocin without-OXTR-abolish arm under that same condition — so OXTR-class-attribution framing survives and oxtr-insufficiency residual fails — when incomplete OXTR block, OXTR-class attribution-not-abolished, absent residual, or block-QC artifacts that would otherwise leave the test inconclusive are ruled out.
