IL27 and atherosclerosis: In the groups modeling the progression of atherosclerosis, the mice treated with IL-27 showed lower counts of Th1 (spleen: 9.7 ± 0.5% vs 13.0 ± 0.5%, respectively; P < 0.001; Figure 5) (blood: 18.0 ± 0.4% vs 22.9 ± 0.7%, respectively; P = 0.001; Figure 6), and Th17 cells (spleen: 1.19 ± 0.06% vs 2.1 ± 0.1%, respectively; P < 0.001; Figure 5) (blood: 0.87 ± 0.06% vs 1.9 ± 0.2%, respectively; P = 0.005; Figure 6) than the PBS-treated mice.
