From: Bronchiolar chemokine expression is different after single versus repeated cigarette smoke exposure
Long-term CS exposure dampens KC and MIP-2 expressions in LCM-retrieved bronchiolar epithelium. Mice were exposed to CS for 4, 12, 18 and 24 weeks and the expression of KC (A) and MIP-2 (B) in LCM-retrieved bronchiolar epithelium (black bars) were determined by real-time RT-PCR. Data represent the average expression relative to β2-MG ± SEM from at least six mice. The part of data in Fig. 5A and 5B are also used for comparison. Statistical significance: * = p < 0.05; ** = p < 0.01; *** = p < 0.001 vs. before CS exposure at day 0.
