Abstract:
Engineered probiotics (EPs) are a group of probiotics whose proteome is manipulated by biotechnological techniques. EPs have attracted a lot of attention in recent researches for preventing and treating chronic diseases. The current study has been conducted to provide an overview regarding the EPs application in the treatment of chronic disease by a comprehensive systematic review of the published articles up to January 2022. To retrieve the related publications, three databases (PubMed/MEDLINE, Web of Sciences, and Scopus) were searched systematically. Finally, all human (n = 2) and animal (n = 37) studies were included. The included articles evaluated the effects of EPs on treatment of arthritis (n = 3), cancer (n = 2), autoimmune encephalomyelitis (EAE; n = 6), Parkinson disease (PD; n = 1), Alzheimer diseases (AD; n = 1), colitis (n = 11), celiac disease (n = 1), diabetes (n = 8) and cardiovascular disease (CVD; n = 6). Induction of oral tolerance (OT) is the most important mechanism of EPs action in the treatment of chronic disease. Providing oral vaccine and bioactive compounds are the other mechanisms of EPs action. PRACTICAL APPLICATIONS: The current systematic review gathered evidence about the application of EPs in the treatment of chronic diseases. Evidence suggests that EPs have very broad and potent effects in the treatment of chronic and even genetic diseases.
