Explores how miR‐16‐5p reduces lung inflammation and fibrosis in asthma using a rat model, suggesting new treatment strategies.

To investigate the role of miR‐16‐5p in regulating airway inflammation and fibrosis in a rat model of asthma.
Created asthma model in male Sprague–Dawley rats using ovalbumin and aluminum hydroxide.
Divided rats into six treatment groups for experimental analysis.
Administered miRNA treatments via PEG-liposomes before each asthma challenge for 8 weeks.
Measured pulmonary function, inflammation levels, and fibrosis outcomes.
Examined interaction of miR‐16‐5p with the TGF‐β1/Smad3 signaling pathway.
Asthma rats showed significantly lower levels of miR‐16‐5p compared to controls.
Elevating miR‐16‐5p levels improved breathing and reduced inflammation.
miR‐16‐5p treatment prevented lung damage and fibrosis by targeting Smad3.
Regulation of the TGF‐β1/Smad3 pathway was confirmed, highlighting miR‐16‐5p's protective role.
