Eps15 and Epsin1 Are Crucial for Enteropathogenic Escherichia coli Pedestal Formation Despite the Absence of Adaptor Protein 2
Bibliographic record
Abstract
Enteropathogenic Escherichia coli (EPEC) are primarily extracellular pathogens that generate actin-rich structures known as pedestals during their pathogenesis. Surprising evidence has demonstrated that despite maintaining an extracellular location, EPEC require the endocytic protein, clathrin, for pedestal formation. To evaluate the strategies EPEC use to usurp endocytic machinery, we investigated the roles of a number of clathrin-coated pits components, adaptor protein 2 (AP-2), Eps15 and epsin1, during EPEC infections. We demonstrated that in conjunction with clathrin, pedestal formation also required the recruitment of Eps15 and epsin1 but not AP-2. Because AP-2 orchestrates the recruitment of clathrin, Eps15, and epsin1, as well as other adaptors, during assembly of clathrin-coated pits at the plasma membrane, our findings reveal a novel internalization subversion strategy employed by EPEC. These results further emphasize the recent paradigm that endocytic proteins are important for EPEC-mediated disease.

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.
