Autotaxin and lysophospholipids in rheumatoid arthritis.
Bibliographic record
Abstract
Autotaxin (ATX) is an autocrine motility-stimulating factor and an extracellular enzyme that catalyzes the hydrolysis of lysophosphatidylcholine (LPC) to lysophosphatidic acid (LPA). Although ATX can also hydrolyze sphingosylphosphorylcholine (SPC) to sphingosine-1-phosphate (S1P), the major source of extracellular S1P originates from the intracellular phosphorylation of sphingosine by sphingosine kinases (SphKs). LPA and S1P are well-characterized bioactive lysophospholipid mediators, which have critical roles in multiple cellular processes through binding and activating GPCRs. These two lipids have been implicated in various physiological (eg, cell growth, differentiation, migration and survival) and pathological (eg, angiogenesis, metastasis and autoimmunity) processes. The roles of LPA and S1P in autoimmune diseases, including rheumatoid arthritis (RA), have recently emerged. This review discusses recent findings suggesting that the LPA- and S1P-induced cellular functions of synoviocytes from patients with RA may contribute to the pathophysiology of the disease by exacerbating the disease process. ATX and the lysophospholipid mediators are potential targets for the treatment of patients with RA.

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.
