Abstract
The stress status of the apoptotic cell can promote phenotypic changes that have important consequences on the immunogenicity of the dying cell. Autophagy is one of the biological processes activated in response to a stressful condition. It is an important mediator of intercellular communications, both by regulating the unconventional secretion of molecules, including interleukin 1β, and by regulating the extracellular release of ATP from early stage apoptotic cells. Additionally, autophagic components can be released in a caspase-dependent manner by serum-starved human endothelial cells that have engaged apoptotic and autophagic processes. The nature and the components of the extracellular vesicles released by dying autophagic cells are not known. In this study, we have identified extracellular membrane vesicles that are released by human endothelial cells undergoing apoptosis and autophagy, and characterized their biochemical, ultrastructural, morphological properties as well as their proteome. These extracellular vesicles differ from classical apoptotic bodies because they do not contain nucleus components and are released independently of Rho-associated, coiled-coil containing protein kinase 1 activation. Instead, they are enriched with autophagosomes and mitochondria and convey various danger signals, including ATP, suggesting that they could be involved in the modulation of innate immunity.

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 it
