Explore how decoding bacterial "conversations" can inform biomedical approaches to treating chronic cystic fibrosis infections. Use bioluminescent bacteria to investigate quorum sensing, model signal transduction pathways that regulate virulence and biofilm formation and evaluate quorum-sensing inhibitors as therapeutic targets. Examine how disrupting bacterial communication - rather than killing bacteria outright - offers an alternative treatment strategy. Leave with classroom-ready models that connect cell signaling, gene regulation, and disease pathology.
