Autophagy Recognizes Intracellular Salmonella enterica serovar Typhimurium in Damaged Vacuoles
Bibliographic record
Abstract
Autophagy is responsible for the degradation of cytosolic components within eukaryotic cells. Interestingly, autophagy also appears to play a role in recognizing invading intracellular pathogens. Salmonella enterica serovar Typhimurium (S. Typhimurium) is an intracellular pathogen that normally resides and replicates within the Salmonella-containing vacuole (SCV). However, during in vitro infection a population of S. Typhimurium damage and escape from the SCV to enter the cytosol. We have observed that some intracellular S. Typhimurium are recognized by autophagy under in vitro infection conditions. Immunofluorescence studies revealed that autophagy recognizes the population of S. Typhimurium within damaged SCVs early after infection. The consequences of autophagic recognition of S. Typhimurium are still being elucidated, though a restrictive effect on intracellular bacterial replication has been demonstrated. Results of our in vitro infection studies are consistent with autophagy playing a role in cellular defense against S. Typhimurium that become exposed to the cytosol.

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.
