Figure 1

Protein levels of TLRs 3, 7, 8 and 9 in human cervical epithelial cells. (a) Representative do plot analysis showing the respective gating for cervical epithelial cells (cytokeratin+ CD45-), leucocytes (cytokeratin-CD45+) and cell debris (cytokeratin-CD45-) based on their forward/sideward scatter characteristics (FSC/SSC) in three independent human cervical samples using flow cytometry. (b) The differential levels of TLRs 3, 7, 8 and 9 in gated cervical epithelial cells were shown in scatter plots as mean fluorescence intensity (MFI). Group 1 = SLE with positive HPV DNA; Group 2 = SLE with negative HPV DNA; Group 3 = Control subjects with positive HPV DNA; Group 4 = Healthy controls with negative HPV DNA.
