Changes of CD8+CD28- T regulatory cells in rat model of colitis induced by 2,4-dinitrofluorobenzene

Figure 1 Body weight of experimental animals was significantly lower than that of controls (P < 0. 01), ○ controls, ● colitis.

Figure 2 Left: Colon histological manifestation of experimental animals (C: 4 × 10, upper left is colon; D: 10 × 10) compared with controls (A: 4 × 10, lower left is colon; B: 10 × 10) (haematoxylin and eosin). Right: Macroscopical and microscopical damage scores in experimental animals are higher than those in controls.

Figure 3 Flow cytometry shows the proportion of CD8+CD28- T regulatory cells was 12. 4% in experimental animals (right) and 4.9% in controls (left).
