In this editorial, we describe how single-cell transcriptomics is advancing the field of intestinal nutrition biology, as highlighted in recent studies. These studies have uncovered potential communication between epithelial and immune cells, generating innovative hypotheses regarding nutrient metabolism in the context of mucosal immunology. We also discuss how emerging spatial transcriptomics and in vivo labeling models may propel conventional technologies forward, in terms of uncovering physical cell-cell interactions and spatial cell-cell communication that can be modulated by nutrient intervention.
