Molecular Clocks in Translational Roadmap for Circadian‐Based Therapeutics in Lung Diseases
The FASEB Journal, Volume 40, Issue 10, 31 May 2026.High‐amplitude circadian oscillations maintain lung immune and epithelial homeostasis. Chronic inflammation dampens peripheral clock amplitude, driving chronodisruption, barrier dysfunction, and remodeling. Clock‐targeted therapies re‐entrain the lung circadian clock, restore rhythmic immune resolution, and promote functional lung repair.
