Abstract

fetched live from OpenAlex

The trimorphic fungus Candida albicans is the leading cause of systemic candidiasis, a disease with poor prognosis affecting immunocompromised patients. The capacity to switch between growth morphologies is tightly coupled to its ability to cause life-threatening infection. Recently, the molecular chaperone Heat Shock Protein 90 (Hsp90) has been implicated as a major regulator of C. albicans morphogenesis via the Ras1-PKA pathway. In model organisms from plant, animal and fungal kingdoms, Hsp90 stabilizes regulators of cell signaling and participates in many important cellular processes. Hsp90’s roles in C. albicans are beginning to be dissected. This thesis represents a comprehensive overview of the morphological response of C. albicans to compromised Hsp90 function, illuminating previously unidentified roles for this chaperone in cell cycle progression, cytokinesis and vacuole maintenance. This work sheds light on the importance of Hsp90 in fungal development and the therapeutic potential of Hsp90 inhibitors in the treatment of fungal infections.

Not 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.
