Additional file 1: Fig. S1. Effects of GPR40 inhibition on airway inflammation in asthmatic mice. (A) The number of total inflammatory cells in BALFs were calculated, and a minimum of 200 cells were employed to classify eosinophils (A), Neutrophils (B), macrophages (C) macrophages (D) and lymphocytes (E) after the last OVA challenge. BALFs were harvested to measure IL-4 (F), IL-13 (G) and IL-8 (H) release by ELISA. The data are expressed as the mean ± S.E.M (n=6). *P<0.05, **P<0.01 and ***P<0.001 compared with the control group, #P<0.05, ##P<0.01 and ###P<0.001 compared with the OVA group. Fig. S2. Mouse lung tissues were collected for the extraction of protein. The expression of GPR40 was measured by western blot. The data are expressed as the mean ± S.E.M (n=4). **P<0.01 compared with the control group, ##P<0.01 compared with the OVA model group
