Intestinal Tuft-2 cells exert antimicrobial immunity via sensing bacterial metabolite N-undecanoylglycine.

Tuft cells are a type of intestinal epithelial cells that exist in epithelial barriers and play a critical role in immunity against parasite infection. It remains insufficiently clear whether Tuft cells participate in bacterial eradication. Here, we identified Sh2d6 as a signature marker for CD45 Tuft-2 cells.
