Serpins are a superfamily of proteins characterized by their common function as serine protease inhibitors. So far, 36 serpins from nine clades have been identified. These proteins are expressed in all the organs and are involved in multiple important functions such as the regulation of blood pressure, hormone transport, insulin sensitivity, and the inflammatory response. Diseases such as obesity, diabetes, cardiovascular, and kidney disorders are intensively studied to find effective therapeutic targets. Given serpins' outstanding functionality, the deficiency or overexpression of certain types of serpin have been associated with diverse pathophysiological events. In particular, we will focus on reviewing the studies evaluating the participation of serpins, and particularly SerpinA3, in diverse diseases that occur in relevant organs such as the brain, retinas, corneas, lungs, cardiac vasculature, and kidneys. In this review, we summarize the role of serpins in physiological and pathophysiological processes, as well as recent evidence on the crucial role of SerpinA3 in several pathologies. Finally, we emphasize the importance of SerpinA3 in regulating cellular processes such as angiogenesis, apoptosis, fibrosis, oxidative stress, and the inflammatory response.
