Research advances on the restorative effect of Periplaneta americana extracts on mucosa

Abstract

In addition to the pharmacological effects of Periplaneta americana extracts (PAEs), including their antitumor, hepatic protection, antioxidant, antibacterial, anti-inflammatory, and tissue regeneration characteristics, their mucosal restorative effects have also attracted significant attention. The mucosa serves as a “gateway” into the body and its functions include the surveillance and clearance of bacteria and pathogens; it also has the immunological function of acquiring beneficial antigens from the external environment and removing non-beneficial ones, a mechanism controlled by the mucosal immune system. In the present study, the relevant modern research literature on the mucosal restorative effect of PAEs was reviewed via a summarization of its restorative effects on respiratory, digestive, dermal, and genitourinary mucosa. The aim of doing so was to present a comprehensive understanding of the mucosal restorative effect of PAEs and their related mechanisms and to provide a reference for their further development and clinical application.
