Dysfunctional RNA‐binding protein biology and neurodegeneration in experimental autoimmune encephalomyelitis in female mice
Bibliographic record
Abstract
Abstract Altered stress granule (SG) and RNA‐binding protein (RBP) biology have been shown to contribute to the pathogenesis of several neurodegenerative diseases, yet little is known about their role in multiple sclerosis (MS). Pathological features associated with dysfunctional RBPs include RBP mislocalization from its normal nuclear location to the cytoplasm and the formation of chronic SGs. We tested the hypothesis that altered SG and RBP biology might contribute to the neurodegeneration in experimental autoimmune encephalomyelitis (EAE). C57BL/6 female mice were actively immunized with MOG 35‐55 to induce EAE. Spinal cords were examined for mislocalization of the RBPs, heterogeneous nuclear ribonucleoprotein A1 (hnRNP A1) and TAR‐DNA binding protein‐43 (TDP‐43), SGs, neurodegeneration (SMI‐32), T cells (CD3), and macrophages (CD68). In contrast to naive mice, mice with EAE showed SG formation ( p < 0.0001) and mislocalization of hnRNP A1 ( p < 0.05) in neurons of the ventral spinal cord gray matter, which correlated with clinical score ( R = 0.8104, p = 0.0253). In these same areas, there was a neuronal loss ( p < 0.0001) and increased SMI‐32 immunoreactivity (both markers of neurodegeneration) and increased staining for CD3 + T cells and IFN‐gamma. These findings recapitulate the SG and RBP biology and markers of neurodegeneration in MS tissues and suggest that altered SG and RBP biology contribute to the neurodegeneration in EAE, which might also apply to the pathogenesis of MS.

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.
