Fig 1. Bacterial supernatants modified expression of immune-related molecules in PDLSC.

Gene expression levels determined by RT-PCR analysis showed upregulation of IL-1β (A) IL-8 (B), IL-6 (C), TLR2 (D) and TLR4 (E) in PDLSCs. Representative blots of at least three independent experiments are shown. Statistically significant differences presented as fold change relative to the untreated negative control (control, open columns) * p < 0.05. Mean ± S.D.
