Mild ER stress contributed to M2a polarization of microglia. a, b Cells were stained with an iNOS or CD206 antibody as indicated. Blue staining represents DAPI. Scale bar, 200 μm. c, d Quantitative data of the mean intensity of iNOS and CD206 fluorescence in primary microglia. Each value is expressed relative to that in the control group, which was set to 100. All experiments were repeated three times. *P < 0.05, **P < 0.01 vs. naïve group. #P < 0.05, ##P < 0.01 vs. LPS treatment group. ^P < 0.05, ^^P < 0.01 vs. TM treatment group. The data are presented as the mean ± SEM
