Abstract:
To initiate pathogenic development, pathogenic fungi respond to a set of inductive cues. Some of them are of an extracellular nature (environmental signals), while others are intracellular (developmental signals). These signals must be integrated into a single response whose major outcome is changes in the morphogenesis of the fungus. The regulation of the cell cycle is pivotal during these cellular differentiation steps; therefore, cell cycle regulation would likely provide control points for infectious development by fungal pathogens. Here, we provide clues to understanding how the control of the cell cycle is integrated with the morphogenesis program in pathogenic fungi, and we review current examples that support these connections.
Insights
Pathogenic fungi use environmental and developmental signals to change shape for infection. Cell cycle regulation is key to controlling this fungal morphogenesis during pathogenic development.
Area of Science:
- Medical Mycology
- Molecular Biology
- Cell Biology
Background:
- Pathogenic fungi require specific signals to initiate infection.
- These signals can be external (environmental) or internal (developmental).
- Fungal morphogenesis, or shape-changing, is crucial for pathogenic development.
Purpose of the Study:
- To explore the integration of cell cycle control with morphogenesis in pathogenic fungi.
- To understand how cell cycle regulation influences fungal development and infection.
- To review current knowledge on the connection between cell cycle and morphogenesis.
Main Methods:
- Review of existing scientific literature.
- Analysis of signaling pathways in fungal pathogens.
- Examination of cell cycle regulatory mechanisms.
Main Results:
- Cell cycle regulation is a critical control point for fungal pathogenic development.
- Integration of extracellular and intracellular cues dictates morphogenesis.
- Specific examples demonstrate the link between cell cycle and developmental changes.
Conclusions:
- Understanding cell cycle control offers insights into fungal pathogenesis.
- Targeting cell cycle regulation could be a strategy against fungal infections.
- Further research is needed to fully elucidate these complex interactions.
