From: Cigarette smoke increases TLR4 and TLR9 expression and induces cytokine production from CD8+T cells in chronic obstructive pulmonary disease

Figure 1

TLR4 and TLR9 are expressed in lung tissue. Endobronchial biopsy tissue sections from COPD patients and control subjects were processed by immunohistochemistry as described in Materials and Methods. Representative examples show similar immunoreactivity for TLR4 in the epithelium and inflammatory cells of control subjects (A) and COPD patients (B). TLR9 was also expressed at comparable levels in the epithelium and inflammatory cells in healthy controls (C) and COPD patients (D). All magnifications are 200×.
