Bacterial lectins: multifunctional tools in pathogenesis and possible drug targets

Area of Science:

• Microbiology
• Glycobiology
• Immunology

Background:

• Glycans are essential macromolecules involved in numerous biological processes.
• Bacterial lectins, carbohydrate-binding proteins, play critical roles in pathogenesis.
• Antimicrobial resistance (AMR) is a major global health threat demanding novel therapeutic strategies.

Purpose of the Study:

• To review current knowledge on bacterial lectins, their functions, and therapeutic potential.
• To highlight bacterial lectins as promising targets for combating AMR.
• To encourage further research into novel lectins and their functions.

Main Methods:

• Literature review of existing research on bacterial lectins.
• Classification of bacterial lectins based on structure and function.
• Analysis of the roles of bacterial lectins in host-pathogen interactions.
• Exploration of therapeutic strategies targeting bacterial lectins.

Main Results:

• Bacterial lectins are involved in host recognition, adhesion, biofilm formation, cytotoxicity, and immune evasion.
• Glycomimetics and vaccines targeting bacterial lectins show early clinical success against AMR infections.
• Several well-characterized bacterial lectins and novel lectins with unknown functions have been identified.

Conclusions:

• Bacterial lectins are critical virulence factors and viable therapeutic targets for AMR.
• Targeting bacterial lectins offers a non-antibiotic approach to combat AMR.
• Further research into novel bacterial lectins is warranted to develop new anti-infective strategies.
