M133 Tconv and Treg proliferation occurs in DCLN and CLN after FTY720 treatment.

<p>(<b>A</b>) Experimental design. M133 Tregs and M133 Tconv were mixed at a 1∶1 ratio and labeled with Violet. 1.5×10⁵ cells were transferred to Thy1 congenic mice one day prior to infection with rJ2.2. Mice were treated with FTY720 or saline 0.5 hour prior to infection and on days 1, 2, 3 p.i. (<b>B</b>) Representative plots showing Violet dilution at day 4 p.i. Numbers are percentage of divided Tregs (upper) or Tconv (lower). (C) Summary of data from three independent experiments with three mice in each.
