Abstract
Brain phospholipids are highly enriched in docosahexaenoic acid (DHA; 22:6n-3). Recent advances indicate that 22:6n-3 is released from brain phospholipids via the action of phospholipase A2 (PLA2) in response to several stimuli, including neurotransmission, where it then acts as a secondary messenger. Furthermore, it is now known that released 22:6n-3 is a substrate for several oxygenation enzymes whose products are potent signaling molecules. One emerging candidate PLA2 involved in the release of 22:6n-3 from brain phospholipids is the group VI calcium-independent phospholipase A2 (iPLA2). After a brief review of brain 22:6n-3 metabolism, cell culture and rodent studies facilitating the hypothesis that group VI iPLA2 releases 22:6n-3 from brain phospholipids are discussed. The identification of PLA2s involved in cleaving 22:6n-3 from brain phospholipids could lead to the development of novel therapeutics for brain disorders in which 22:6n-3 signaling is disordered.

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
