Abstract: Objectives: Lung is one of the vital organs that is affected by the ageing process. Searching for natural antioxidants is mandatory to boost healthier longevity. Accordingly, we sought to explore the probable protective effect of Coenzyme Q10 (Q10) on experimentally induced lung ageing and study the supposed involved mechanistic pathways. Methods: Rats were allocated into groups; control, D-galactose (D-gal), D-gal + Q10 and D-gal + Q10+ LY294002 (LY; phosphatidylinositol 3-kinases (PI3K)/protein kinase B (AKT) inhibitor). Sera and lung tissues were gathered for evaluating markers of oxidative stress, inflammation, fibrosis, and cell senescence by different methods.Immunohistochemistry for senescence associated beta galactosidase (SA-βGal), Capsase-3, and P53 were also evaluated. Results: Induction of lung ageing resulted in deleterious lung alterations which were ameliorated by Q10; however, its protective effect was abolished by co-administration of LY. Conclusion: Q10 secured the lung against the ageing process via its antioxidant, anti-inflammatory, and anti-apoptotic effects through the activation of the PI3K/AKT/Nrf-2 pathway.
