Overview
- Researchers describe continuous cross-talk among the liver, intestine and brain via blood, the vagus nerve and immune signaling.
- Key metabolic pathways, including tryptophan–serotonin, link intestinal serotonin production to hepatic regulation with system-wide effects.
- The INMEGEN team reports reduced INMT expression in people with liver cancer compared with healthy livers, indicating a potential progression marker.
- Investigators say early detection can allow reversal of liver injury and help restore physiological balance.
- Advanced dysfunction can lead to ammonia buildup and hepatic encephalopathy, as well as varices and intestinal alterations, prompting calls for medical follow-up, balanced nutrition, regular exercise, less alcohol and ultraprocessed foods, good sleep and no self-medication.
