Candida albicans Secreted Aspartic Protease 7 is Essential for Damage of Human Oral Epithelial Cells
Bibliographic record
Abstract
Aims: Candida albicans is an important human fungal pathogen in clinical settings. It possesses a wide spectrum of virulence traits, including but not limited to the production of Secreted Aspartic Proteases (SAPs), to invade host cells under predisposing conditions. The aims of the present study were to investigate the functional role of C. albicans SAP7 in invasion ability. Methods: The present study was carried out to construct C. albicans sap7Δ/Δ mutant strain using a PCR-based gene disruption method. The behaviors of this SAP7 knockout strain was evaluated and compared with the wild type and SAP7 complemented strains between human oral epithelial cells with respect to endocytosis, invasion, and tissue damage. Results: Compared with the wild type C. albicans strain, a 52% reduction in the endocytosis of the sap7Δ/Δ mutant strain by oral epithelial cells was observed, as well as a 25% attenuation of internalization, and a 27% reduction of tissue damage (P<0.05). Conclusion: Our data clearly demonstrates that C. albicans SAP7 contributes to tissue invasion into human oral epithelial cells which warrant further investigations as potential targets for antifungal interventions.

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.
