Abstract
Abstract Proteinase‐activated receptors (PARs) represent a novel family of G‐protein coupled receptors that mediate the diverse biologic effects of proteinases on target cells. Four different members of the PAR family have been identified so far: PAR 1 , PAR 3 , and PAR 4 act as receptors for thrombin, and PAR 2 is activated by trypsin/tryptase. It is now known that all four subtypes of PARs are widely expressed in the central nervous system, and there is increasing evidence to suggest roles for proteinases and PARs in development and pathogenesis in the nervous system. Harnessing different G proteins and a variety of signal transduction cascades, PARs can affect neural cell proliferation, morphology, and electrical activities. PARs have also been considered as major players in neuroinflammatory/degenerative processes in which they play both neuroprotective and neuropathogenic roles. The advent of PARs agonistic and antagonistic peptides, which selectively activate their cognate receptor and mediate a broad spectrum of PAR‐executed effects in the nervous system, makes these peptides attractive therapeutic possibilities. Herein we review different aspects of PARs activities in the normal development and function of the brain and address some evidence related to PARs roles in nervous system pathogenesis with a focus on neuroinflammatory/degenerative disorders.

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 it
