Expression of CXCR5, CCR7, and P-Sel-Lig on adoptively transferred DO11.10 T cells. After transferring CFSE-labeled lymphocytes from DO11.10 mice into Balb/c mice recipients were immunized with OVA plus CT. Cells from the dLNs were isolated at the time points indicated. (A) The percentage of KJ1-26⁺ cells expressing CXCR5 is shown for individual mice (○); bars represent mean values (data shown derive from 4 independent experiments). The expression of CXCR5 (B) and CCR7 (C) on KJ1-26⁺ T cells 4 days after antigen application is shown in relation to CSFE dilution, which indicates cell proliferation. (C) Expression of CXCR5 and CCR7 (D) and CXCR5 and P-Sel-Lig (E) on KJ1-26⁺ cells 4 days after immunization. Similar data were obtained in 3 to 6 additional experiments.
