Analysis of the expression of TLR-2 (panel A), TLR-4 (panel B) and CD14 (panel C) in peripheral blood monocytes from never smokers (n = 22), AECOPD (n = 20) and COPD (n = 13) patients and smokers (n = 20). Shaded area represents TLR staining of monocytes from a representative AECOPD patient. The un-shaded area outlined by the darker line represents TLR staining in monocytes from a representative never smoker. The un-shaded area outlined by a thin line represents isotype matched PE labelled antibodies staining in monocytes from the AECOPD patient. The results were analyzed by one-way analysis of variance with Bonferroni contrasts.
