Figure 2From: Smoking decreases the response of human lung macrophages to double-stranded RNA by reducing TLR3 expressionAMø TLR3 expression does not correlate with lung function or total duration of smoking exposure. AMø were harvested, processed and analyzed as described in the legend to Figure 1. A-C. TLR3 mRNA transcripts by quantitative real-time PCR (smokers, n = 11; never-smokers, n = 6, except in panel C, which includes only current or former smokers). D-F. Flow cytometric analysis of TLR3 protein expression (smokers, n = 13; never-smokers, n = 10, except in panel F which includes only current or former smokers). A, D: FEV1 % predicted; B, E: participant age (years); C, F: smoking history (pack-years); note the difference in the vertical scale of panel F. Blue circles, smokers; red crosses, never-smokers. p values by Spearman correlation.Back to article page
