Description

Johnathan D Keith and co-authors test a cystic fibrosis drug in rats in this 2024 study. The drug, ivacaftor, boosts a faulty channel protein that causes the disease. New drug mixes have changed life for patients, yet lung bacteria still persist, and the reasons were unclear. The team used rats carrying a human version of the faulty gene to see how the drug affects infection over time.

Rats given the drug had fewer lung bacteria and fewer immune cells in airways in the early phase of infection. In the later, chronic phase those gains vanished, though mucus plugs were fewer and weight recovery was better. The channel itself worked at normal levels throughout. The authors conclude the drug helps rats tolerate infection rather than clear it.
