Experimental Diabetic Neuropathy With Spontaneous Recovery
Bibliographic record
Abstract
Progressive diabetic neuropathy has hitherto been irreversible in humans. New approaches raise the question of whether islet cell reconstitution rendering euglycemia can reverse specific features of neuropathy. We evaluated physiological and structural features of experimental neuropathy in a long-term murine model of diabetes induced by streptozotocin. By serendipity, a subset of these diabetic mice spontaneously regained islet function and attained near-euglycemia. Our hypotheses were that this model might better reflect axon loss observed in human disease and that spontaneous recovery from diabetes might identify the features of neuropathy that are reversible. In this model, experimental neuropathy closely modeled that in humans in most critical aspects: declines in motor conduction velocities, attenuation of compound muscle (M waves) and nerve action potentials, axon atrophy, myelin thinning, loss of epidermal axons, and loss of sweat gland innervation. Overt sensory neuron loss in dorsal root ganglia was a feature of this model. In mice with recovery, there was robust electrophysiological improvement, less myelin thinning, and remarkable epidermal and sweat gland reinnervation. There was, however, no recovery of populations of lost sensory neurons. Our findings identify a robust model of human diabetic neuropathy and indicate that overt, irretrievable loss of sensory neurons is one of its features, despite collateral reinnervation of target organs. Sensory neurons deserve unique protective strategies irrespective of islet cell reconstitution.

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.
