Il22ra2 was exclusively detected in CD11b+ and CD11c+ myeloid cells, but not in Thy1.2+ T cells, CD19+ B cells or other CD45+ cells in both colonic polyp and non-polyp tissues (Fig. 6e), and its expression was mainly detected in CD11c+ DCs, but not in CD11c–CD11b+ or other myeloid cells (Fig. 6f). This evidence concerns the gene CD19 and polyp.
