This pathway encompasses both SMAD-dependent canonical pathway and SMAD-independent non-canonical signaling pathway. Heritable thoracic aortic aneurysms and dissection are highly correlated with genetic alterations in TGF-β canonical signaling-related genes. However, depending on the stage of the disease, the TGF-β signaling pathway can have either inhibitory or aggravation effects, making its roles in aortic disease complex and occasionally contradictory. This review aims to elucidate the biological mechanisms underlying the TGF-β signaling pathway in the most common aortic diseases, namely acute aortic syndromes and aortic aneurysms, and to evaluate the potential clinical application of TGF-β-targeting therapies in aortic diseases.
