Bacterial lectins: multifunctional tools in pathogenesis and possible drug targets

International audience. Glycans are vital macromolecules with diverse biological roles, decoded by lectins – specialized carbohydrate-binding proteins crucial in pathogenesis. The WHO identifies bacterial antimicrobial resistance (AMR) as a critical global health challenge, necessitating innovative strategies that also target non-antibiotic pathways. Recent studies highlight bacterial lectins as key players in pathogenesis and promising therapeutic targets, with early clinical success using glycomimetics and vaccines to treat and prevent AMR-related infections. This review covers the current knowledge on bacterial lectins, their classifications, and roles in host recognition and adhesion, biofilm formation, cytotoxicity, and host immune evasion, with examples of well-characterized lectins. It also explores their therapeutic potential and highlights novel lectins with unknown functions, encouraging further research.
