Semaglutide cuts MUC5AC mucin in cell and mouse airway model

The wire

1. 01In Frontiers in Immunology, semaglutide and pioglitazone were most effective at lowering MUC5AC expression and reactive oxygen species in bronchial cells and C57BL/6 mice exposed to Pseudomonas aeruginosa pyocyanin.
2. 02The authors frame repurposed semaglutide as a possible adjunct in COPD, a use well outside current metabolic indications clinicians see.
3. 03Work is confined to cell cultures and a mouse chronic bronchitis model; no human data support an airway indication.
