Methods: This review is aimed to explore the alterations of intestinal microbiota and metabolome associated with metabolic and cardio-cerebrovascular diseases, as well as the potential application of engineered bacteria in treating these conditions.

There are a large number of people suffer from metabolic, cardiovascular, and cerebrovascular diseases, posing a significant threat to public health. Previous studies have suggested that cardiovascular and cerebrovascular diseases are frequently accompanied by changes in intestinal flora and metabolites, which play a crucial role in the progression of metabolic, cardiovascular and cerebrovascular diseases. Engineered bacteria, as a tool for efficiently expressing foreign genes within a bacterial cell line, has attracted considerable attention for cancer treatment over the past decades. In recent years, engineered bacteria has been extended to metabolic disorders, cardiovascular and cerebrovascular diseases therapy and has been a promising tool. However, several challenges persist, including the necessity of more refined strain selection and design. Furthermore, there is no relevant review on the application of engineering bacteria in the fields of metabolic diseases and cardiovascular diseases currently. Therefore, this review is aimed to explore the alterations of intestinal microbiota and metabolome associated with metabolic and cardio-cerebrovascular diseases, as well as the potential application of engineered bacteria in treating these conditions.
