Expression of C2GlcNAcT-I correlates with P-selectin ligands but not with E-selectin ligands on activated T cells.

Two-color analysis of 1B11 versus P-RIgM (A) or E-RIgM (B) in WT Th1 cells. Concordant staining is seen with P-RIgM, but not with E-RIgM, where 1B11⁺/E-RIgM⁻ and 1B11⁻/E-RIgM⁺ subsets are also seen. (C, D) Analysis of C2GlcNAcT-I^−/− Th1 cells as for panels A and B. As expected, no staining is seen for 1B11 or P-RIgM (C), but a clear subset of cells is E-RIgM⁺ but 1B11⁻(D).
