ECIG-aerosol exposure inhibited phagocytosis of E.coli. MQ reduced phagocytosis of E. coli. after exposed to ECIG-aerosol (A) Statistical significance (p ≤ 0.05) between Sham and exposure (nicotine or without nicotine) condition was indicated as * in each group Control group, CD36 shRNA group and control shRNA group). CD35 and CD64 expression was downregulated in ECIG-aerosol-exposed MQ (B) and (C). Statistical significance (p ≤ 0.05) between Sham and exposure (nicotine or without nicotine) condition was indicated as *
