Abstract
Mammalian spinal cord injury (SCI) occurs by a primary mechanical trauma that is exacerbated by a secondary cellular insult in the form of neuroinflammation, cell death, and reactive gliosis. The lack of functional recovery may be attributed to the inability of mammals to replace lost neurons. In zebrafish (Danio rerio), the secondary insult is attenuated and allows for the development of a spinal microenvironment that fosters regeneration. Radial glia lining the zebrafish central canal undergo injury-induced proliferation and neuronal differentiation, yet the molecular mechanisms that underlie these processes remain elusive. Previous reports have identified roles for purinergic P2Y2 and P2X7 receptors in mammalian neural progenitor cell proliferation and neuronal differentiation, respectively. Given that the purinergic system is evolutionarily conserved among vertebrates, we hypothesize that radial glia proliferation and neurogenesis following zebrafish SCI may be mediated by P2X7 and P2Y2 signaling. Preliminary immunohistochemical data suggests that radial glia express P2X7 and P2Y2 receptors. Preliminary Western blotting data shows significant upregulation of P2Y2 receptor expression at 1 day following zebrafish SCI, as well as significant downregulation of P2X7 receptor expression at 7 days. This contrasts the more gradual increase in P2Y2 receptor expression as well as the general increase in P2X7 receptor expression following mammalian SCI. Specific blockers for P2X7 and P2Y2 will be used to ascertain the roles of these receptors in the zebrafish SCI response. This work is well suited to advance our current understanding of successful central nervous system regeneration and elucidate the signaling pathways involved.

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
