PI3K activity is not essential for T cell motility within LN slices. Control (Ctl; green) and WMN-treated (red) T cells were adoptively transferred 2 h before the recording. The animation represents a 40-┬Ám z-projection with 30-s frame intervals. Note the accumulation of WMN-treated cells in restricted areas of the LN that correspond to HEVs (Fig. S4).
