Nutrition & DietCommon Amino Acid Methionine Boosts Kidney Power to Fight Deadly Inflammation
Researchers at the Salk Institute discovered that methionine, a common dietary amino acid, helped mice survive severe infections by boosting kidney function rather than directly targeting the immune system. When mice with serious infections received methionine supplements, they were protected from wasting, brain barrier damage, and death caused by runaway inflammation. The kidneys, enhanced by methionine, filtered out excess pro-inflammatory cytokines before they could accumulate and damage tissues. This finding reframes the kidney as an active defender against inflammatory disease and suggests that targeted nutritional interventions could meaningfully shift disease trajectories. Published in Cell Metabolism, the study points toward potential applications in inflammatory conditions, kidney disease, and dialysis patients.
