Delayed and short course of rapamycin prevents organ rejection after allogeneic liver transplantation in rats

Figure 5 A short course of rapamycin increases myeloid-derived suppressor cells numbers on postoperative day 11 in allogeneic liver-grafted rats. The spleens of grafted animals were collected on day 11 and day 42, and myeloid-derived suppressor cells (MDSCs) were analyzed by flow cytometry. A: Gating strategy for MDSC analysis: CD11b/c⁺CD161^intMCH class II^-; B: Cumulative data indicating MDSC percentages. The results are expressed as the mean +/- SEM of the MDSC percentages. P-values are indicated when the differences between the two groups of rats are significant (^bP ≤ 0.01).
