Levels of pro-inflammatory mediators in lungs of ApoE^-/-mice exposed to CS. The levels of pro-inflammatory mediators such as MCP-1 (A) and KC (B) were measured by ELISA in lung homogenates of air- and CS-exposed WT and ApoE^-/- mice. Data are shown as mean ± SEM (n = 3-4 mice per group). **P < 0.01, ***P < 0.001, significant compared with corresponding air-exposed mice. ⁺P < 0.05, ⁺⁺P < 0.01 significant compared with CS-exposed WT mice. ^#P < 0.05, significant compared with air-exposed WT mice
