Figure 2. Effect of siRNA-PEI-loaded MPs on cytokine levels.
Anti-FcγRIII-siRNA-PEI-loaded PLGA MPs reduced protein-level expression of inflammatory cytokines interleukin-6 (IL-6) and IL-1β. Protein was extracted from retrodiscal TMJ tissue on day 9 of the experiment, and then interleukin levels were measured via ELISAs. Values for each group are expressed relative to the total protein content; data points represent the mean ± standard error of the mean for n = 6 rats. In each panel, groups marked with * differ significantly from all other groups, while pairs of groups marked with ** or *** differ significantly from all other groups but not each other (p < 0.05).
