Single cell sequencing of the nodose ganglia

Guided by gut sensory cues, humans and animals prefer nutritive sugars over non-caloric sweeteners. But how the gut differentiates such stimuli to rapidly guide preferences remains unknown. In the intestine, innervated enteroendocrine cells synapse with the vagus nerve to convey luminal sugar stimuli to the brain within seconds. Here, we sequenced individual vagal nodose neuron cells from the left and right nodose to assess their relative contribution to sugar signaling from the gut. The neurons lack expression of sugar receptors and transporters, but do express receptors for neurotransmitters and neuropeptides secreted by intestinal sensory epithelial cells.
