Figure 2

Quantification of TLR4 and TLR9 in COPD and control subjects. The degree of epithelial staining of TLR4 (A) and TLR9 (B) were scored according to a scale (1 = no staining; 5 = 100% staining) following immunostaining. The numbers of the positively stained immune cells were also counted, and the area of the tissue was measured. There was no significant difference in the percentage of TLR4- (A) or TLR9- (B) stained epithelium between the two groups. There was also no significant difference in the total number of inflammatory cells expressing TLR4 (C) and TLR9 (D) between the control group and COPD patients, when expressed as cells/mm2 tissue.
