Purine-ifying uric acid by gut microbes

Elevated bloodstream levels of uric acid, a mammalian purine degradation product, are associated with several noncommunicable diseases. Recent studies by Kasahara et al. and Liu et al. define purine-degrading activities of the gut microbiota that lower bloodstream uric acid in atherosclerosis and gout disease models, establishing a novel microbial role in host health.
