FTY720 Effects on Inflammation and Liver Damage in a Rat Model of Renal Ischemia-Reperfusion Injury

Figure 3

FTY720 sequesters peripheral T cells with a differential treatment effect on splenic T cell populations. Rats underwent renal ischemia by the surgical placement of a microvascular clamp around the left renal pedicle of the anesthetized rat. Rats received a single intravenous bolus of either vehicle control (black circle) or 0.3 mg/kg FTY720 (gray square) 15 min after placement of the clamp. Treatment groups were euthanized at 6, 24, or 72 hrs. Peripheral blood (a, b) and isolated splenocytes (c, d) were prepared for flow cytometry analysis by staining for T cell markers CD4, CD8, and αβ. Data are presented as the calculated number of circulating cells per mL of blood and per spleen (-10 rats per time point/group). compared with vehicle control at the same time point postinjury.
