Effects of ECIG-aerosol exposure on MQ polarization and inflammatory response in MQ cultured at air–liquid interface. ECIG-aerosol induced MQ polarization markers CD86 and CD11c (A). The ECIG-aerosol exposure induced levels of inflammatory cytokines in gene level (B) and in secreted protein level (C). Statistical significance (p ≤ 0.05) between Sham and exposure (nicotine or without nicotine) condition was indicated as * and between nicotine and without nicotine was indicated as #
