Tachykinins: Effects on Motility and Metabolism of Rat Polymorphonuclear Leucocytes
Bibliographic record
Abstract
Chemotactic and chemoluminescent activities of substance P, substance K, kassinin and the substance P fragments SP 4-11, SP 7-11, SP 1-4 have been investigated in order to identify the minimum active molecular structure responsible for rat polymorphonuclear activation. Substance P, SP 4-11 and SP 7-11 stimulated directed locomotion (chemotaxis) and were found to be active also in the chemoluminescence assay while SP 1-4 had no effect. Moreover, all peptides, except substance K and SP 1-4, inhibited the chemotactic response of polymorphonuclears to the peptide formyl-methionyl-leucyl-phenylalanine and, to a minor extent, also to leukotriene B4. A maximum of activity was observed with the C-terminal sequence SP 4-11. Substance K was found to be inactive. Kassinin exhibited a weak chemotactic effect and exerted a slight inhibition of attracting activity of peptide-formyl-methionyl-leucyl-phenylalanine. Considering that substance P and related peptides are active only at very high concentrations, it cannot be affirmed that these agents activate specific receptors. If receptors are involved, they would be of the SP-P type, since substance K is inactive.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
