FTY720 decreases cerebral lymphocyte invasion.

<p>(<b>A</b>) Brain sections were stained 5d after MCAO for T cells (CD3), B cells (B220), granulocytes (MPO) and activated microglia/macrophages (IBA1). (<b>B</b>) Analysis of absolute cell counts of T cells, B cells, granulocytes and microglia/macrophages per total hemisphere in PBS and FTY720 treated animals at 5d after MCAO (n = 6–10 per group, 2–3 individual experiments).
