This study identifies intestinal serotonergic vagal signaling as a key mediator of microbiota-induced hypertension, showing that reduced 5-HT and 5HT3aR signaling contributes to hypertension and can be reversed to alleviate it.

This study shows that Rspo2 from gustatory neurons is essential for taste bud maintenance through genetic experiments in mice.

The paper shows that hepatic vagal afferents transmit circadian signals between the liver and brain, influencing food intake and body weight.

This study investigates the role of the vagus nerve in regulating liver metabolism, finding that its ablation alters hepatic proteome and promotes lipid accumulation and steatosis.

The paper identifies lateralized vagal sensory neurons with distinct roles in satiety and food preference, revealing asymmetrical gut-brain circuits that control feeding behavior.

The paper identifies separate vagal reward circuits for fat and sugar that drive overeating when both are activated, even when calorie intake is controlled.

The paper shows that central and peripheral GLP-1 systems independently suppress eating, and PPGNTS neuron activation addsitively enhances this effect with GLP-1 agonists.
