Figure 2. Comparison of monocytes, NK, and ${gamma}$ ${delta}$ T-cell activation between aggressive periodontitis patients and non-periodontitis subjects (n = 17, each group). Whole-blood cultures were incubated with P. gingivalis LPS (0, 1, 3, 10 ng/mL) for 48 hrs. (A) Up-regulation of monocyte CD40, CD80, and CD86 expression was analyzed by flow cytometry. Each symbol represents MFI-fold increase of each individual. Horizontal lines are means. (B). Up-regulation of CD69 expression on NK and ${gamma}$ ${delta}$ T-cells was analyzed by flow cytometry. Each symbol represents % positive cell-fold increase of each individual. Horizontal lines = means.
