Shape-Shifting Mechanisms: Integrative Multi-Omics Insights Into Candida albicans Morphogenesis

Area of Science:

• Microbiology
• Molecular Biology
• Mycology

Background:

• Candida albicans exhibits morphological plasticity, switching between yeast, hyphal, and pseudohyphal forms, which is crucial for its pathogenicity.
• Cyclic adenosine monophosphate (cAMP)-dependent signaling has been traditionally viewed as the primary driver of hyphal growth in C. albicans.

Purpose of the Study:

• To review and integrate findings from multi-omics studies on Candida albicans morphogenesis.
• To elucidate the complex regulatory networks controlling C. albicans shape-shifting, including both cAMP-dependent and independent mechanisms.

Main Methods:

• Integration of transcriptomic, proteomic, and phosphoproteomic data.
• Analysis of signaling pathways regulating fungal morphology.

Main Results:

• Morphological changes in C. albicans are driven by both cAMP-dependent and independent mechanisms.
• Basal protein kinase A (PKA) activity, cyclin-dependent kinases (e.g., Cdc28), and other regulators influence shape-shifting.
• N-acetylglucosamine (GlcNAc) induces hyphal growth independently of its metabolic function, linking environmental cues to morphological states.

Conclusions:

• Complex regulatory networks govern C. albicans morphogenesis, involving intricate signaling pathways.
• Advanced multi-omics approaches are essential for a comprehensive understanding of these pathways.
• Further research can elucidate pathway convergence, environmental responses, and potential therapeutic targets for modulating fungal behavior.
