Glycan-mediated adhesion mechanisms in antibiotic-resistant bacteria

Area of Science:

• Microbiology
• Immunology
• Glycobiology

Background:

• Bacterial adhesins are key virulence factors mediating host-pathogen interactions.
• Many adhesins specifically bind to host glycans, influencing colonization and immune evasion.
• The World Health Organization has identified several bacterial pathogens as critical threats requiring novel therapeutic strategies.

Purpose of the Study:

• To review and summarize known glycoconjugate targets of bacterial adhesins.
• To focus on adhesin-glycan interactions in critical bacterial pathogens.
• To provide a foundation for developing new anti-bacterial therapies.

Main Methods:

• Literature review of scientific publications.
• Identification and categorization of bacterial adhesins and their glycoconjugate targets.
• Focus on pathogens designated as critical threats by the WHO.

Main Results:

• Compilation of glycoconjugate targets across 19 bacterial genera and species.
• Detailed summary of adhesin-glycan interactions relevant to critical pathogens.
• Identification of common and unique binding strategies.

Conclusions:

• Understanding adhesin-glycan interactions is vital for combating critical bacterial pathogens.
• This review consolidates knowledge on targets for therapeutic intervention.
• The findings support the development of novel anti-adhesin or glycan-based therapies.
