Figure 4From: Cigarette smoke-promoted acquisition of bacterial pathogens in the upper respiratory tract leads to enhanced inflammation in mice Expression of inflammatory mediators in the upper respiratory tract. Mice were exposed to CS or air for 7 months and intranasally inoculated with NTHi. Total RNA was obtained by flushing the upper airways with lysis buffer. The expression of mBD-1 (A), lysozyme (B) and MIP-2 (C) was determined by qRT-PCR. Data are shown as mean ± SEM. n = 4 per group.Back to article page
