Viral mimicry and memory deficits upon microglial deletion of ATRX
Bibliographic record
Abstract
Abstract The importance of chromatin-mediated processes in neurodevelopmental and intellectual disability disorders is well recognised. However, how chromatin dysregulation in glial cells impacts cognitive abilities is less well understood. Here, we demonstrate that targeted loss of the ATRX chromatin remodeler in microglia alters chromatin accessibility profiles, leading to the de-repression of endogenous retroelements, triggering viral mimicry. Functionally, we find that ATRX microglial deficiency alters the electrophysiological properties of hippocampal neurons and causes deficits in object recognition and spatial memory. Overall, these findings demonstrate that ATRX is required in microglia to preserve chromatin structure and maintain microglial homeostasis. Disruption of these functions elicit neuroinflammation and cognitive deficits and potentially contribute to the pathology of human neurological disorders caused by ATRX mutations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
