Plantago asiatica L. extract alleviates hyperuricemia-associated renal injury by modulating gut microbiota to inhibit NLRP3 inflammasome activation

This study demonstrates that PTGA exerts hypouricemic and renoprotective effects through modulation of the gut-kidney axis by enriching Lachnospiraceae, promoting intestinal uric acid catabolism, and suppressing renal NLRP3 inflammasome activation. These findings provide novel mechanistic insights into the gut microbiota-dependent therapeutic action of herbal medicine, distinguishing this work from previous studies focused solely on direct organ-level effects.
