P31 — Substance P residual phenotype under NK1R/Tacr1 abolish
Substance P is framed as supporting nociception, neurogenic inflammation, and stress attribution through NK1R-class (Tacr1) attribution, yet that framing is often assumed to exhaust the phenotype. This discussion asks whether residual Substance P phenotype under Tacr1/NK1R genetic LOF or NK1R-matched antagonism (e.g. RP67580 / CP-96345 / aprepitant-class) that abolishes NK1R-class nociception / neurogenic-inflammation / stress attribution still requires a path beyond NK1R-class attribution.
Claim
On a matched rodent nociception / neurogenic-inflammation / stress-attribution panel (Cao-class tachykinin pain / neurogenic-inflammation endpoints, Garret-class RP67580 NK1 antagonist tool QC, Hershey-class NK1R identity honesty, or De Felipe-class Tacr1 LOF stress/aggression/wind-up QC style matched rodent panel) ± Substance P ± NK1R-matched antagonism (RP67580 / CP-96345 / aprepitant-class) or Tacr1 genetic LOF titrated so the block abolishes NK1R-class nociception / neurogenic-inflammation / stress attribution, plus nociceptive or neurogenic-inflammation or stress/aggression endpoint: under that NK1R-abolish condition, residual Substance P phenotype remains ≥50% of the Substance P without-NK1R-abolish arm on the same panel (named comparator = Substance P without-NK1R-abolish arm under matched panel) — assumption-kill / nk1r-insufficiency.
Why it matters
Cao maps primary afferent tachykinin pain / neurogenic-inflammation phenotype via Tac1/PPT-A ligand KO (SP+NKA; intact NK1R expected; not Tacr1 residual — Tac1≠Tacr1 CRITICAL); Garret maps RP67580 selective NK1 antagonist TOOL; Hershey maps SP receptor = NK1R identity FOUNDATION (SP IS canonical NK1R ligand); De Felipe maps Tacr1/NK1R KO tool + stress/aggression/wind-up necessity (abstract does NOT test exogenous SP-in-KO retain). P31 asks whether residual Substance P phenotype under Tacr1/NK1R genetic LOF or NK1R-matched antagonism that abolishes NK1R-class attribution still requires a path beyond NK1R-class attribution — nk1r-insufficiency assumption-kill. Distinct from P15–P29; ESPECIALLY ≠P30 (NK1R≠RAMP1; SP≠CGRP; Q_P30_tight=1 NON-MATCH); ≠P29 OX1R; ≠P28 VPAC2; ≠P27 Y1; ≠P26 PAC1; ≠P25 GHSR; ≠P24 GLP1R; ≠P23 OXTR; NOT FOXO4×LOF; skip-list unused; orthosteric_drift=false; SP-is-NK1R-ligand honesty; MRGPRX2/NK2/NK3/hemokinin-1 caveats (document; do not invent residual); necessity ≠residual-positive.

Mechanism sketch
nk1r-insufficiency assumption-kill: Cao shows primary afferent tachykinins required for moderate-to-intense pain via PPT-A/Tac1 ligand KO (encodes Substance P and neurokinin A; behavioural response to moderate-to-intense pain reduced; neurogenic inflammation almost absent) LITERATURE — phenotype PRIOR with intact NK1R expected; NOT residual under NK1R abolish; do NOT confuse Tac1−/− with Tacr1−/− CRITICAL; Garret shows RP67580 potent selective nonpeptide substance P (NK1) antagonist TOOL LITERATURE (competitive NK1; inactive on NK2/NK3; blocks plasma extravasation / neurogenic inflammation; analgesic in writhing/formalin — not residual H2H); Hershey shows molecular characterization of rat substance P receptor — GPCR identity FOUNDATION / necessity-leaning NK1R attribution LITERATURE — SP IS canonical NK1R ligand; residual under NK1R abolish would imply non-NK1R bridge; empty residual expected OK; De Felipe shows mice lacking the receptor for substance P (NK-1 / Tacr1 KO) — wind-up and intensity coding of nociceptive reflexes absent; SP essential for full stress-induced analgesia and aggressive response to territorial challenge LITERATURE — Tacr1 genetic LOF TOOL + necessity-leaning; abstract does NOT test exogenous Substance P retain in KO — NOT residual-positive SP-in-KO H2H.

Actionable limitations
- Do not treat P1–P30 as proving P31 — Cao Tac1 phenotype, Garret antagonist tool, Hershey NK1R identity, De Felipe Tacr1 LOF stress/aggression necessity, and RP67580-occlusion necessity priors are not a residual-under-NK1R-abolish H2H for Cao/Garret/Hershey/De Felipe panels; soft-complete empty ≠demonstrated residual phenotype; do not invent residual when EMPTY/UNKNOWN; do not treat necessity as residual-positive; do not misread Cao Tac1 as Tacr1 residual; do not misread De Felipe LOF as residual-positive SP-in-KO; document SP-is-NK1R-ligand / MRGPRX2 / NK2 honesty.

- remove matched nociception / neurogenic-inflammation / stress-attribution panel ± Substance P ± NK1R-matched antagonism or Tacr1 LOF under NK1R-abolish that first abolishes NK1R-class nociception / neurogenic-inflammation / stress attribution, then scores residual Substance P phenotype: Without the NK1R-abolish × residual H2H, separate Cao phenotype LITERATURE, Garret tool LITERATURE, Hershey identity LITERATURE, De Felipe LOF/stress necessity LITERATURE, and RP67580-occlusion necessity LITERATURE cannot show nk1r-insufficiency of residual Substance P under NK1R-abolish on the claimed panel.
- remove NK1R-abolish gate plus Substance P without-NK1R-abolish arm as the named residual comparator (vs Cao phenotype-alone / Garret tool-alone / Hershey identity-alone / De Felipe stress-alone / RP67580 necessity-alone): Without the NK1R-abolish gate and Substance P without-abolish comparator under the same block condition, the card collapses into Cao/Garret/Hershey/De Felipe phenotype / tool / identity / necessity prior or generic NK1R-class framing and loses nk1r-insufficiency contrast.
