Tauopathies: Calmodulin Regulates Tau Hyperphosphorylation and Its Transformation into Disease-Specific Aggregates
Bibliographic record
Abstract
Tauopathies are a diverse group of neurodegenerative diseases characterized by the presence of Tau inclusions in neurons and glia. Rather than the classic steps in the transformation of Tau into neurofibrillary tangles, as first studied in Alzheimer's disease, studies on tauopathies reveal the presence of diverse Tau aggregates that appear to be disease-specific. Regardless, the phosphorylation and hyperphosphorylation of Tau, involving various kinases and phosphatases, appear to be central to all tauopathies. As in other neurodegenerative diseases, calcium dysregulation is an early event in multiple tauopathies, where it activates calmodulin to effect downstream events. Here, the events of Tau phosphorylation and hyperphosphorylation, which involve several CaM-dependent kinases and a single CaM-regulated phosphatase, are covered. In addition, CaM has been linked to other events, including Tau aggregation. As a central player in tauopathies, CaM offers several alternative therapeutic routes that are worth investigating. For example, evidence is presented here that supports targeting specific binding motifs of key CaM-regulated Tau kinases as a novel therapeutic approach.

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.
