Mouse studies suggest gut microbiota that express N-acylphosphatidylethanolamines (NAPEs) could help treat or prevent obesity. In mice fed a high-fat diet, drinking water containing Escherichia coli engineered to express NAPE decreased food intake, adiposity, insulin resistance and hepatosteatosis compared with drinking water containing control bacteria or water without added bacteria. In a polygenic mouse model of obesity, NAPE-expressing E. coli decreased weight gain compared with control bacteria or vehicle. Next steps could include evaluating the safety of the bacteria.
