For ( a , c ), human CD4 + T cell subgroups were isolated by FACS from the blood of healthy donors as in Supplementary Fig. and Fig. . a CCR6 +(high) CCR2 + cells were either left untreated (marked with a minus sign) or treated with CCL2 (100 ng/ml) just before and for four min after adding the cells to the flow chambers, and CCL2-treated cells were used without (marked with a minus sign) or with treatment with the CCR2 antagonist, BMS22. Data points in the left panel show numbers of cells rolling, arrested, and transmigrated, while the middle panel shows arrested cells as percentages of cells rolling and the right panel shows transmigrated cells as percentages of cells arresting. Each symbol shows data from one donor, with n = 4 individual donors in four separate experiments using CCL2. Two of these experiments included the additional treatment with BMS22. b Above is the CCL2-CXCL9 chimera sequence with signal peptide sequence shown in green, CCL2-sequence in black, and C-terminal GAG-binding sequence of CXCL9 in red.

Cytokine-activated endothelial cells upregulate expression of selectins and integrin ligands and secrete chemokines. Selectin-selectin ligand interactions help capture cells and allow them to roll along the endothelium. For pathogenic-like type 17 cells, endothelial cell-bound chemokines can then stimulate CCR6, CCR5, and CXCR3 to activate integrins for binding to intercellular adhesion molecules and mediate firm arrest. Secreted chemokines that fail to adhere to endothelial cells, such as CCL2 and other CCR2 ligands, are removed by blood flow to create a transendothelial gradient that drives TEM. Although for the sake of clarity the T cell depicted here co-expresses the four chemokine receptors, not all CCR6 +(high) CCR2 + CD4 + T cells express CCR5 and/or CXCR3.
