Recent Breakthrough Increases Efficacy of Cystic Fibrosis Drugs

Different bacteria affects treatment in different ways

Émilie Maillé is the lead author of the study, as well as a research assistant within Brochiero's laboratory. She explains how the bacterial quorum-sensing gene lasR is able to control many harmful particles, "during the disease, this bacterial gene mutates and the production of harmful products varies. Our work confirms that different bacterial strains, depending on whether they come from acute infections - especially in young patients - or chronic infections - especially in older patients - affect treatment efficacy in different ways."
