Most CD8α+CCR2+ cells are MAIT cells and all CD8α+ MAIT cells express CCR6.

(A) Expression of CCR2 on CD8α+ memory-phenotype cells and frequencies of TCR Vα7.2+ CD161+ (MAIT) cells within the CCR2+ and CCR2- subsets (top), and expression of CCR2 within the MAIT cell population (bottom). Cells are shown from one representative of more than 30 donors. (B) Expression of chemokine receptors on naive CD8α+ T cells and memory-phenotype CD8α+ T cells divided into the following subsets: TCR Vα7.2 CCR6 (CCR6- conventional), TCR Vα7.2 CCR6+ (CCR6+ conventional), TCR Vα7.2+ CCR6+ CCR2-/low (CCR2-/low MAIT), and TCR Vα7.2+ CCR6+ CCR2+ (CCR2+ MAIT); shades of red reflect percentages of cells positive for each chemokine receptor as determined by flow cytometry and as displayed in each box. Data are averaged from cells from nine donors. (C) Expression of CCR6 on MAIT cells (right) and TCR Vα7.2+ CD161- cells (left). Numbers are percentages of cells within a quadrant or demarcated region. Cells are shown from one representative of six donors.

The 5’ flanking regions of FUT7, ST3GAL4, and CCR6 contain sequences predicted to bind C/EBPδ.

Schematic presentation of computationally predicted C/EBPδ-binding sites. Bindings sites for each gene were predicted in a 20,000 bp region immediately upstream from the start of transcription (TSS, indicated by the arrow). For each gene, the corresponding NCBI RefSeq number and the transcription start site genomic coordinate are provided below the gene name. Each black vertical bar indicates a predicted binding site on the sense strand (pointing up) or anti-sense strand (pointing down). Red boxes indicate C/EBPδ binding regions revealed by ChIP assays in Figure 7 that contain predicted C/EBPδ binding sites. * Because FUT7 is annotated on the anti-sense strand, the reverse-complement of the region was queried and displayed.
