Pannexin‐1 in the CNS: Emerging concepts in health and disease
Bibliographic record
Abstract
Pannexin-1 (Panx1) is a large pore membrane channel with unique conduction properties ranging from non-selective ion permeability to the extracellular release of signalling molecules. The release of ATP by Panx1 has been particularly well-characterized with implications in purine signalling across a variety of biological contexts. Panx1 activity is also important in inflammasome formation and the secretion of pro-inflammatory molecules such as interleukin-1β. Within the central nervous system (CNS), Panx1 is expressed on both neurons and glia, and is thought to mediate crosstalk between these cells. A growing body of literature now supports the pathological activity of Panx1 in contributing to disease processes including seizure, stroke, migraine headache and chronic pain. Emerging evidence also reveals a physiological function of Panx1 in regulating neural stem cell survival, neuronal maturation and synaptic plasticity, with possible relevance to normal cognitive functioning. The aim of this review is to summarize the current evidence regarding the roles of Panx1 in the CNS, with emphasis on how putative signalling properties and activation mechanisms of this channel contribute to various physiological and pathophysiological processes.

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.
