Dioleoyl‐phosphatidic acid selectively binds to α‐synuclein and strongly induces its aggregation
Bibliographic record
Abstract
α-Synuclein (α-syn), which causally links to Parkinson's disease, binds to vesicles containing phosphatidic acid (PA). However, the effects of the fatty acyl chains of PA on its ability to bind to α-syn protein remain unclear. Intriguingly, we reveal that among several PA species, 18:1/18:1-PA is the most strongly bound PA to the α-syn protein. Moreover, 18:1/18:1-PA more strongly enhances secondary structural changes from the random coil form to the α-helical form than 16:0/18:1-PA. Furthermore, 18:1/18:1-PA more markedly accelerates generation of multimeric and proteinase K-resistant α-syn protein compared to 16:0/18:1-PA. These results indicate that among phospholipids examined so far, 18:1/18:1-PA demonstrates the strongest binding to α-syn, as well as the most effective enhancement of its secondary structural changes and aggregation formation.

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.
