Researchers have successfully engineered gut microbes to combat kidney stone formation. These genetically modified bacteria are designed to absorb key compounds, like oxalate, that contribute to the development of kidney stones. Furthermore, the microbes are engineered to thrive within the complex and competitive gut microbiome environment. This innovative approach offers a potential preventative or therapeutic strategy for individuals prone to kidney stones, addressing the issue at its source within the digestive system. Further research is focused on optimizing the microbes for long-term efficacy and safety in human trials.
