Ammonia Metabolism in the Aging Liver: Emerging Mechanistic Insights

Age-related liver dysfunction disrupts ammonia metabolism, linking hepatic aging to brain and muscle decline.

This Aging Cell review synthesizes emerging evidence on how age-related liver dysfunction leads to impaired ammonia metabolism and systemic ammonia accumulation, connecting hepatic aging to cognitive impairment, sarcopenia, and reduced healthspan. The findings position ammonia dysregulation as a targetable systemic biomarker of biological liver aging with potential therapeutic implications.
