Fig. 6From: Cigarette smoke alters the ability of human dendritic cells to promote anti-Streptococcus pneumoniae Th17 responseIn vitro exposure to cigarette smoke extract (CSE) induced an oxidative stress in monocyte-derived dendritic cell (MDDC) from healthy subjects activated by S. pneumoniae (Sp). a Expression of Heme-oxygenase (HO)-1 was evaluated by qRT-PCR in MDDC exposed to CSE and then activated or not by S. pneumoniae for 6 h. b Mitochondrial oxidative stress was measured by flow cytometry by measuring the fluorescence of MitoSox in MDDC exposed to CSE and then activated or not by S. pneumoniae for 6 h. Data represent mean ± S.E.M of 4 and 6 experiments for a and b, respectively. *P < 0.05Back to article page
