Engineering quorum sensing: new directions for antimicrobial therapy.

Synthetic biology approaches to quorum sensing can be harnessed to develop innovative antimicrobial strategies targeting bacterial virulence and resistance.

• Why it matters: Bacterial quorum sensing is crucial for host colonization and pathogenicity, and disrupting it offers a promising avenue for antimicrobial therapy.
• What they did: Researchers review how QS and QS interference are used to engineer circuits in microorganisms, with applications including therapeutic microbes and pathogen detection.
• The result: This work underscores the transition of QS research from basic microbiology to translational biotechnology, enabling new methods to combat microbial virulence and antimicrobial resistance.
