Figure 6. Transfer of CCR9^−/− or β7^−/− T cells impairs OT in wt mice.

T cells from CCR9^−/− or β7^−/− mice were adoptively transferred into wt mice. OT and DTH were induced as described in Fig. 1. (A) DTH responses were measured after 24h (n= 2 mice/group). Groups were compared versus wild type mice receiving oral PBS. (B) Total splenocytes were stimulated with the indicated OVA concentrations and cell proliferation was measured after 72h (n= 2 mice/group). Mean ± SEM, *p<0.05 (ANOVA)
