Peroxisomes exhibit compromised structure and matrix protein content in SARS-CoV-2-infected cells
Bibliographic record
Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus that has triggered global health and economic crises. Here we report the effects of SARS-CoV-2 infection on peroxisomes of human cell lines Huh-7 and SK-N-SH. Peroxisomes undergo dramatic changes in morphology in SARS-CoV-2-infected cells. Rearrangement of peroxisomal membranes is followed by redistribution of peroxisomal matrix proteins to the cytosol, resulting in a dramatic decrease in the number of mature peroxisomes. The SARS-CoV-2 ORF14 protein was shown to interact physically with human PEX14, a peroxisomal membrane protein required for matrix protein import and peroxisome biogenesis. Given the important roles of peroxisomes in innate immunity, SARS-CoV-2 may directly target peroxisomes, resulting in loss of peroxisome structural integrity, matrix protein content and ability to function in antiviral signaling.

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.
