Diabetes prolongs mRNA levels of inflammatory cytokines. Induction and resolution of periodontitis and application of TNF inhibitor were performed as in Fig. 1. IFN-γ (A), TNF-α (B), and IL-1β (C) mRNA levels were measured in RNA extracted from rat periodontium by RT-PCR. +P < 0.05 vs. diabetic group.
