Temporary retention of effector TCs by modulating S1P1r expression on newly differentiated TCs (SPearly). (a) Reducing SPearly resulted in higher total TC number. (b) Number of effector TCs exited was affected more by SPearly than by Vmax, negatively correlating with SPearly (R2 > = 0.92, p < 0.005). SPearly negatively correlated with (c) CD8+ TCs exited (R2 > 0.92, p < 0.005) and (d) CD4+ TCs exited (R2 > 0.91, p < 0.005). (e). The mean number of cognate TCs contacted increased as SPearly was lowered to 0.1 at each Vmax but overall decreased with Vmax.
