The Mechanistic Function of the NOD-like Receptor NLRX1 in Apoptosis and Cell Death in the Nervous System
Bibliographic record
Abstract
The mitochondrial protein NLRX1 belongs to the family of cytosolic nucleotide-binding and oligomerization domain (NOD)-like receptors (NLRs). NLRs respond to invasive pathogens, and danger signals released from dead or dying cells. The function of NLRX1 was previously reported to be in anti-viral immunity, however we propose a non-immune role for this protein in apoptosis. We show here the function of NLRX1 to be inhibitory to extrinsic apoptosis and permissive to intrinsic apoptosis. Furthermore, we validate the previously reported interaction between NLRX1 and sterile-α and TIR motif containing protein 1 (SARM1). SARM1 is expressed in the nervous system, and has a pro-apoptotic function in addition to its role in promoting Wallerian degeneration. We found NLRX1 to have both SARM1-dependent and -independent functions during apoptosis. Furthermore, we test NLRX1 function during Wallerian degeneration following axotomy, and a central nervous system injury model involving ischemic stroke.

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.
