This systematic review and meta-analysis evaluated the effects of quercetin in preclinical models of pulmonary fibrosis, analyzing 24 studies with 570 animals. The findings indicate that quercetin significantly reduced fibrotic scores and fibrosis-related biomarkers, likely through its anti-inflammatory and antioxidant properties. However, the senolytic effects remain inconclusive.
Key findings
- Quercetin significantly reduced fibrotic scores in animal models of pulmonary fibrosis.
- The expression of fibrosis-related biomarkers was also significantly decreased with quercetin treatment.
- The beneficial effects of quercetin were linked to its ability to attenuate inflammation and oxidative stress.
Why it matters
Understanding the potential therapeutic effects of quercetin on pulmonary fibrosis could inform future treatment strategies. Given the disease's progressive nature, exploring new interventions is crucial for improving patient outcomes.
What to keep in mind
The study highlights risk of bias and heterogeneity among the included studies, suggesting caution in interpreting the results.
