TLR4 interference reverses the effects of the FimA fusion protein on PBMC proliferation. (A) The expression levels of TLR4 mRNA were detected by reverse transcription quantitative polymerase chain reaction following treatment of PBMCs with or without siTLR4 transfection. Cell proliferation was detected by Cell Counting Kit-8 following treatment of PBMCs with 2, 4 and 6 μg/ml FimA fusion protein for (B) 12, (C) 24 and (D) 48 h and transfection with siTLR4. Data are expressed as the means ± standard deviation based on at least three independent experiments; *P<0.05 vs. the control group (negative siRNA-transfected). TLR4, toll-like receptor 4; FimA, Porphyromonas gingivalis fimbriae; PBMC, peripheral blood mononuclear cells; si, small interfering.
