Flow cytometry analysis showed significantly increased recruitment of CD45+CD4+Ccr6+ (Th17) cells and CD45+CD4–Ccr6+ (expected as a B cell–rich fraction) cells in arthritis tissue from Uhrf1ΔCol6a1 mice in the late but not early phase of STA (Figure 5K and Supplemental Figure 4G). This evidence concerns the gene CCR6 and Arthritis.
