The Flo Adhesin Family

Area of Science:

• Medical Mycology
• Molecular Biology
• Biochemistry

Background:

• Fungal pathogen adhesion to host tissues and medical devices is a critical initial step in human infections.
• Cell wall adhesins are key molecular players mediating this crucial adhesion process.

Purpose of the Study:

• To review the Flo adhesin family and their specific roles in fungal adhesion during human infections.
• To establish a new classification for Flo adhesins based on domain architecture and function.
• To identify and discuss yeasts expressing Flo adhesins relevant to human infections.

Main Methods:

• Literature review and analysis of existing research on Flo adhesins.
• Redefinition of the Flo adhesin family based on domain structures and known functions.
• Pfam database mining to identify yeasts expressing Flo adhesins.
• Analysis of solved Flo adhesin structures to understand adhesion mechanisms.

Main Results:

• A redefined classification of the Flo adhesin family based on domain architecture.
• Detailed discussion of the structure, function, and adhesion mechanisms of solved Flo adhesins.
• Identification of specific yeast species encountered in human infections that express Flo adhesins, along with their architectural features.

Conclusions:

• The Flo adhesin family plays a significant role in fungal adhesion to host cells and abiotic surfaces.
• Understanding Flo adhesin structure and function provides insights into fungal pathogenesis.
• Identification of relevant yeasts and their adhesin architectures aids in developing strategies against fungal infections.
