However succinate receptor SUCNR1 and free fatty acid receptor FFAR3, proposed as ‘sensing’ receptors in murine tuft cells, are not expressed, and instead ovine tuft cells are enriched for taste receptor TAS2R16 and mechanosensory receptor ADGRG6. We also identify tuft cell sub-clusters at potentially different stages of maturation, suggesting a dynamic process not apparent from mouse models of infection. This evidence concerns the gene FFAR3 and infection.
