Driving Therapeutic Innovation in Neurodegenerative Disease With Hydrogen Deuterium eXchange Mass Spectrometry
Bibliographic record
Abstract
Human neurodegenerative conditions such as Parkinson's and Alzheimer's disease are characterized by the formation and deposition of toxic protein species which exacerbate neuronal dysfunction, impacting the structure and function of the healthy brain. Deciphering the mechanisms underlying protein (mis)folding and aggregation is not only essential for a more coherent view of neurodegeneration, but also crucial for the development of novel therapeutics targeting this family of disorders. Key pathological drivers of neurodegeneration, such as alpha-synuclein and tau proteins, have traditionally proved extremely challenging to characterize structurally due to their intrinsic and widespread structural plasticity. Hydrogen-Deuterium eXchange Mass Spectrometry has emerged as a powerful tool to help circumvent this, owing to its ability to capture protein intrinsic disorder in solution, in addition to the transient structural conformations that typify protein aggregation pathways. This review brings together the most recent research where Hydrogen-Deuterium eXchange Mass Spectrometry has shed light on mechanisms of neurodegeneration. We highlight how the technique has been successfully integrated into therapeutic development workflows targeting some of the most prevalent neurodegenerative diseases.

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.
