The emerging role of group VI calcium-independent phospholipase A2 in releasing docosahexaenoic acid from brain phospholipids
Bibliographic record
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 machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
