Immunohistochemical reaction with diaminobenzidine (DAB) as a chromogen. Objective magnification 40×. Red arrows mark the area of connective tissue of dermis where immunoexpression of Toll-like receptors 2 (TLR2) and 4 (TLR4) was visible as brown pigmentation; white arrows mark the keratinocytes of epidermis where immunoexpression of TLR2 was visible as brown pigmentation. Abbreviation: C—uninfected immunocompetent mice (n = 5), CS—uninfected immunosuppressed mice (n = 5), A—immunocompetent Acanthamoeba spp. infected mice (n = 5), AS—immunosuppressed Acanthamoeba spp. infected mice (n = 5).

Figure Lengend Snippet: Each cell line was examined for total ( A, D ), cell surface ( B, E ) and intracellular ( C, F ) TLR4 expression by flow cytometry using the mouse anti-human TLR4-APC antibody. Percentage of total, cell surface and intracellular TLR4 positive cells for cell line groups are shown in panels ( A – C ). Displayed in panels ( D – F ) are mean fluorescent intensities (MFI) of TLR4 positive cells in each genotype group. All data are presented as mean ± SEM of three independent experiments. Statistical comparisons were performed using One-way ANOVA and Newman-Keuls post-hoc test among the TLR4 genotype groups (n = 3) except the Asp299Gly/Thr399Ile cell group (n = 2).

Figure Lengend Snippet: Shown in panels ( A – D ) are comparisons of dose-response curves to LPS stimulations of cell lines in each TLR4 genotype group. 3.0×10 5 cells were stimulated for 24 hours with a series of LPS concentrations and conditioned media from each cell line was tested for human IL-8 secretion by ELISA. (I) Human IL-8 production 24 hours after LPS treatment for different genotype cell groups. WT-LPS-0 and WT-LPS-20 represent TLR4 wild type cell lines stimulated with 0 and 20 ng/ml LPS (same annotation for other cell groups). ( E – H ) Percentage of TLR4- and EGFP-positive cells that are also positive for IL-8 as assessed by flow cytometry analysis. ( J ) Fold change (percentage multiplied by MFI) of intracellular human IL-8 positive cells after LPS(20 ng/ml)stimulation for the four genotype groups. # no LPS stimulation vs 20 ng/ml LPS stimulation within the same genotypic cell group, P <0.05; ** and *** vs Asp299Gly group, p <0.01 (I) and 0.001(J).
